The analysis makes use of wind field data from Hurricane Katrina initially gathered by field
researchers from Texas Tech University and Florida International University and others, with
subsequent analysis by the NOAA Hurricane Research Division and Applied Research
Associates (ARA). The data sharing among these research groups is gratefully acknowledged.
Loss estimates and effectiveness of mitigation options were determined using FEMA’s HAZUSMH
Hurricane Wind Model, MR1 Release 39 (copyright 2004, FEMA).
Loss estimates are highly dependent on the maximum wind speeds in a hurricane and the
geographical extent of hurricane force winds. There are currently several researchers on the
ground in Louisiana and Mississippi gathering as much information as they can find on the
intensity and reach of Katrina’s wind field. As new data becomes available, a reanalysis of the
estimated losses may yield somewhat different results.
Partial funding for the study was provided by Solutia, Inc, which is also gratefully
acknowledged.

EXECUTIVE SUMARY
In order to provide context for consideration of changes to residential building codes and
construction practices in Louisiana, a quick study of the estimated wind damage caused by
Hurricane Katrina was conducted. As Louisiana did not experience the most intense winds from
Katrina due to its track over the very eastern part of the state, a ‘what if’ analysis was also
conducted with a Katrina-like storm shifted slightly to the west, bringing more of the windfield
over Louisiana. Both of these storm events were then used to investigate the impacts of several
different changes in building code requirements/construction practices. Mitigation measures
considered were opening protection (impact resistant shutters or laminated glass systems),
improved connection of the roof deck, installation of hurricane straps, and secondary moisture
protection of the roof deck. Damage estimates and the effectiveness of various mitigation
measures were made using FEMA’s HAZUS-MH Hurricane Wind Model, a state-of-the-art risk
assessment program for analyzing hurricane losses.
The number of residential structures in Louisiana that sustained damage from wind and winddriven
rain during Hurricane Katrina was estimated to be near 273,000, 16% of the total building
stock in Louisiana. Had Katrina made landfall slightly west of New Orleans instead of just east
of the city, the number of damaged and destroyed buildings in Louisiana would have been
doubled, to well over half a million residences.
Investigation of mitigation options showed all to be effective individually. When considered
together as a package, these four combined mitigation measures reduced the estimated losses by
over 75%.
The loss reduction estimates using different mitigation techniques do not include such additional
benefits as reduction in human suffering, reduced disruption of communities and local
economies, reduced emergency response costs, and other significant but difficult to quantify
losses.
These preliminary results support the need for reforms in building code requirements and
construction practices in Louisiana.

RESIDENTIAL LOSS ANALYSIS
The HAZUS-MH Wind Model was used to simulate the wind field experienced during Hurricane
Katrina. The model inputs were based upon a preliminary study of surface winds produced by
Applied Research Associates (ARA). The ARA modeled storm was based on National
Hurricane Center Forecast/Advisories (through NHC Advisory 27), H*Wind analyses of wind
speeds and radius to maximum winds from NOAA’s Hurricane Research Division (HRD) and
ground-measured wind speeds from the Florida Coastal Monitoring Program (FCMP) and
reporting airports.
The modeled wind field for Hurricane Katrina in Louisiana is shown in Figure 1. A large scale
map of the affected portion of Louisiana is shown in Figure 2. Wind speeds represent peak gusts
at 33 ft height over flat open terrain, the standard reporting methodology for wind speeds.
Figure 1 – Estimated Hurricane Katrina Peak Gust Wind Speeds
Figure 2 – Estimated Hurricane Katrina Peak Gust Wind Speeds (Southeast LA view)

To simulate the landfall of Hurricane Katrina on a more damaging path, each of the points used
to define the track of Hurricane Katrina was shifted 0.7 decimal degrees (approximately 40
miles) to the west. This track puts New Orleans on the right front side of the storm, where it will
experience more severe winds and flooding. This hypothetical Katrina-West scenario was
analyzed with the HAZUS Wind Model to produce a wind field for purposes of comparison with
the actual Katrina track. The modeled wind field for the adjusted storm track in the state of
Louisiana is shown in Figure 3. A larger scale map of the southeast corner of Louisiana is
shown in Figure 4.

The HAZUS-MH Hurricane Model uses a structural load vs. resistance methodology to calculate
damage experienced in a hurricane. The wind speeds discussed previously are the most
important inputs to determine the wind loads on the structures. The damage results provided by
HAZUS include five damage states: none or very minor, minor, moderate, severe, and
destruction. Qualitative descriptions for each of these damage categories are given below in
Table 1.

A building damage and loss analysis was completed for Hurricane Katrina using the default
settings for the HAZUS program. The state of Louisiana was used as the study region.
According to the HAZUS databases, the study area contains approximately 1,719,000 total
buildings (based on 2000 census data). From the HAZUS databases, residential buildings
constitute approximately 99% of the buildings in the study region.
The output of the HAZUS model provides building counts for each of damage categories shown
above. The Hurricane Katrina analysis results are given in Table 2. Counts represent the
estimated total number of affected buildings in Louisiana, and percentage figures represent the
percent of buildings in each of the categories. Maps of the areas affected by Hurricane Katrina
winds are shown in Figures 5 and 6. Figure 5 presents a graphical depiction of residential
properties modeled by HAZUS that sustained at least minor damage, delineated by census tract,
and Figure 6 shows properties experiencing at least moderate damage. The total estimated
damage from wind and rain (including costs to repair and loss of contents) is $10.0 billion.

A HAZUS analysis was also conducted for the simulated Hurricane Katrina on a more westerly
track. The estimated damage results are given in Table 3 below. This storm is shown to cause
much more damage. It effects more than twice as many buildings and destroys several times as
many as indicated by the Katrina estimate

ANALYSIS OF EFFECTIVENESS OF MITIGATION MEASURES
Both the actual Hurricane Katrina track and the modified track west of New Orleans were
analyzed with the HAZUS Hurricane Model to explore the effectiveness of improved building
codes and construction practices in mitigating wind damage. The mitigation options are based
upon strategies incorporated in the Dade County South Florida Building Code, described below
(see the HAZUS Technical Manual for more details).
􀂃 Protection of Building Openings
Windows and doors are the weak spots in the wall envelope. Requiring debris impact
resistant windows and doors or debris impact protective coverings (shutters) prevents
most window and door failures. This helps keep the wind and rain out of the building,
reducing structural damage, damage to finishes, and damage to contents.
􀂃 Improved Roof Sheathing Attachment
Better attachment of the plywood or OSB roof sheathing to the roof structure through
appropriate fasteners and closer fastener spacing helps prevent sections of the roof deck
from being lifted off by the wind. This reduces progressive failures and wind and water
from penetrating the building envelope.
􀂃 Improved Roof-Wall Connections
Installation of metal ‘hurricane clips’ or’ hurricane straps’ provides a continuous load
path from the roof to the foundation, helping prevent catastrophic roof uplift failures.
􀂃 Secondary Waterproofing to Roof Joints
Sealing the joints between the sheets of roof decking provides a second line of defense
against roof leaks, even if the roof coverings are damaged or destroyed.

Reduction in Building Damage Through Mitigation
The four mitigation strategies were applied to each hazard scenario individually to assess the
effectiveness of each option. A combined analysis was also performed to provide an
understanding of the effectiveness of the combination of mitigation measures. Results for this
analysis are given in the same format as for the Katrina analysis, with building counts in each
damage state and the percentage of buildings statewide that are classified in each damage state.
Additionally, the percent reduction from the basic Hurricane Katrina analysis is calculated for
each damage state.
Note that reduction in damage is not modeled by selecting secondary waterproofing for roof
joints, but results for waterproofing are included in the economic loss analysis. The results of the
mitigation analysis are given for Hurricane Katrina in Tables 4-7. Mitigation analysis results for
the hypothetical Katrina-West track (not shown here) resulted in similar percent reductions.

Reduction in Economic Loss through Mitigation
Using the mitigation strategies outlined above, HAZUS was also used to provide cost estimates
of direct losses. Direct property damage losses are the estimated costs to repair or replace the
damage caused to the building and its contents. Information from the HAZUS databases
indicates that the Louisiana study region consists of 1,718,706 buildings with an aggregate total
replacement value (excluding contents) of $235.9 billion (2002 dollars). Residential buildings
make up 86% of the building value in the state of Louisiana, with total replacement value of
$203.3 billion.
The analysis for Hurricane Katrina estimates total losses (including business interruption) in the
state of Louisiana of $13.1 billion. Residential losses make up 89% of the total loss at $10
billion. Mitigation strategies were evaluated to assess the economic effectiveness of
strengthening the residential building stock in the study area. Mitigation alternatives shutters on
exterior openings, straps/clips at the roof to wall connection, upgraded roof deck attachment,
secondary waterproofing for roof joints for single family, multi-family and mobile home
9
dwellings. Each of these mitigation strategies was applied to 100% of the study region building
stock individually to assess the economic loss reduction effectiveness. An analysis combining
all available mitigation strategies was also completed.
Table 8 provides economic loss information modeled by HAZUS for Hurricane Katrina. These
values represent modeled residential building and contents losses in the state of Louisiana.
Percent of total replacement value represents the total residential losses normalized by the total
replacement value of residential buildings in the state ($203.3 billion). Percent reduction reflects
the reduction in economic losses for each mitigation option from the default analysis. Reduction
in economic losses was seen at approximately the same percentages for each mitigation option in
the hypothetical Katrina-West simulation.

INSTALLATION NOTES
Proper planning for your DuraTech Chimney installation will result in greater safety,
efficiency, and convenience, as well as saving time and money. You must use only
authorized DuraTech Chimney parts to maintain a listed Chimney system (not
including the connector pipe). Do not mix parts or try to match with other products,
or use improvised solutions. Do not install damaged or modified parts. Table 1 lists
the authorized DuraTech Chimney components. Practice good workmanship.
Sloppy work could jeopardize your chimney’s safety. Keep electrical wiring and
insulation away from all chimneys and stovepipes. If you have any questions, be
sure to contact either your dealer or Simpson Dura-Vent directly.
CHIMNEY DIAMETER
Follow the appliance manufacturer’s instructions to determine chimney diameter
and clearances between combustible materials and your heating appliance. Never
choose a chimney with an inside diameter smaller than your appliance’s outlet. To
calculate the chimney’s outside diameter, add 2 inches to the inside diameter.
CHIMNEY HEIGHT
The National Fire Protection Association Standard #211 states: “Chimneys shall
extend at least three feet above the highest point where it passes through the roof
of a building, and at least two feet higher than any portion of a building within
ten feet.” (Fig 1) DuraTech Chimney may be installed up to 60 feet high. If the
chimney extends more than 5 feet above the roof, an Extended Roof Bracket must

be used (see page 12). Due to the overlap of
the joints, subtract 1-1/4 inches from each
Chimney Section’s height to calculate installed
height.
CHIMNEY PLACEMENT
When deciding the location of your chimney,
try to avoid modifications to roof beams and other structural components of the
building.
CHIMNEY ENCLOSURE REQUIREMENTS
Through Rooms: Interior chimneys shall be enclosed where they extend
through closets, storage areas, occupied spaces, or anyplace where the surface
of the chimney could be contacted by persons or combustible materials. The
space between the outer wall of the chimney and the enclosure shall be at least
2 inches (Fig 2).
Multi-Story: Consult local building codes for requirements in your area. In the
U.S., the National Fire Protection Association Standard #211 states: “Factorybuilt
chimneys that pass through floors of buildings requiring the protection of
vertical openings shall be enclosed with approved
walls having a fire resistance rating of not
less than one hour when such chimneys are
located in a building less than 4 stories in height,
and not less than 2 hours when such chimneys are
located in a building more than 4 stories in height.”
In Canada, except in single-family and twofamily
dwellings, chimneys which extend through
another story must have an enclosure with a fire
resistance rating equal to or greater than that of
the floor or roof assembly through which they
pass.
Cold Climates: In cold climates, chimneys
mounted on an outside wall should be enclosed in
a chase. Exterior chases reduce condensation
and creosote formation, and enhance draft. Include
an access door by the Tee Cap for chimney
cleaning (Refer to Fig 23, page 17).

STOVE RECOMMENDATIONS
Follow the stove manufacturer’s instructions. The requirements stated below
pertain to all stoves or other appliances installed with DuraTech Chimney systems.
Choice: Choose an appliance that is listed by a recognized testing laboratory, is
appropriate for your needs, and is not larger than required.
Installation: Once the chimney system is in place, install the stovepipe to
connect the appliance to the chimney as described in the appliance manufacturer’s
instructions. Be sure to maintain all required clearances.
Flues: Connect only one solid fuel appliance per chimney.
Operation: Follow the appliance manufacturer’s instructions for maximum efficiency
and safety. Overfiring can damage the appliance, stovepipe and chimney.
Fuels: Do not burn driftwood, plastic, or chemically treated wood such as railroad
ties. They are corrosive to your appliance, stovepipe and chimney. Follow the
appliance manufacturer’s instructions and safety manual in regards to fuels. Not all
appliances are equipped to burn coal. Coal with a low sulfur content will reduce
the possibility of corrosion.
Mobile Homes: Please read the appliance manufacturer’s instructions and safety
manual carefully. Not all appliances are listed for use in mobile homes.
STEP-BY-STEP DIRECTIONS
There are five general types of DuraTech Chimney installations:
1. Ceiling-supported 2. Roof-supported
3. Tee-supported (through-the-wall) 4. Masonry Fireplace
5. Zero-Clearance Fireplace
Review the step-by-step directions before beginning your installation.
CEILING SUPPORTED
1. Place Appliance: Position the appliance according to the manufacturer’s
instructions. The flue outlet collar should be placed between the rafters or joists
above, if possible.
2. Frame Support Opening: Drop a plumb bob to the center of the appliance’s
flue outlet and mark this center point on the ceiling. Refer to Table 2 for specific
framing and clearance dimensions. Mark appropriate cutting lines around the
center point. Cut a square hole in the ceiling for the Support Box. Frame a level,
square opening centered over the hole which you have cut. (Figures 3 and 4).
3. Install Support: For installation into a flat ceiling, you may use either the Round
Support Box, the Flat Ceiling Support Box, or the Square Ceiling Support Box. The
6
Flat Ceiling Support Box is primarily used for Oil Appliances and comes unpainted.
For the Square Ceiling Support Box, refer to the Square ceiling installation below.
The Round Ceiling Support Box has the option of a square or round Trim Collar
available (Fig 5). The bottom of the Round Support Box must extend at least 3
inches below the finished ceiling. Level the Support Box and secure it to the framing
using at least three 8-penny nails per side (min. of 12 total). Alternatively, you may
use 1-1/2″ #8 wood screws (min. of 12 total), instead of nails. Next, secure the Trim
Collar (round or square) to the framing members using the (4) 1″ long, round-head
wood screws provided (Fig 6).
For installation into a cathedral ceiling, you must use the Square Ceiling Support
Box and the two-piece Trim. The bottom of the square portion of the Support Box
must be a minimum of 2-inches lower (round portion is an additional 3 inches lower)
than the finished ceiling at the lowest side of the penetration (Fig 5 & 6). Level the
Support Box and secure it to the framing using
at least three (3) 8-penny nails per side (minimum
of 12 nails total), or a minimum of (3) #8, 1-1/
2″ wood screws. Adjust the overlapping “Ushaped”
Trim pieces so they cover the Support

using the (6) 1-1/4″ long, round head wood screws provided (see Fig 6).
4. Frame Openings: Frame openings in each ceiling or floor above the Support
Box (Fig 7). These openings are to hold the Firestop Radiation Shield and Attic
Insulation Shield. Locate each opening by dropping a plumb bob to the four
corners of the opening below. Maintain the minimum clearances and dimensions
as specified in Table 2. If Elbows must be used to avoid an obstruction,
refer to the Offset Elbow Installation section.
5. Cut Roof Opening: Cut an opening in the roof directly above the opening
below, and at least 4 inches larger than the chimney’s outside diameter to
provide at least a 2-inch clearance all around the chimney. The chimney must
be centered within this opening and maintain the 2-inch clearance to combustibles.
6. Install Firestop Radiation Shield: A Firestop Radiation Shield is required
in multistory installations at each floor penetration above that where the Support
Box is located. Example: in a multistory home where the appliance is on the ground
floor (Support Box is in the 1st floor ceiling), you would need a Firestop Radiation
Shield at the 2nd floor ceiling, and at the 3rd floor ceiling, etc., including where the
chimney penetrates into the attic. Figure 7 shows a typical 2-story installation with
an attic. Note: a Firestop Radiation Shield is not installed where the chimney
penetrates through the roof. The Firestop Radiation Shield is installed on the
underside of the ceiling/floor framing, with the cylindrical “tube” portion of the shield

pointing upward (Fig 8). Use a
minimum of either (1) 8 penny nail
or (1) #8, 1-1/2″ wood screws per
corner. Refer to Table 2 for framing
requirements.
7. Assemble Chimney Sections:
Lower the female end of the first
Chimney Section in the Support
Box (Fig 9). It will twist-lock
clockwise onto the male end of the
Support Box. Turn Pipe Sections
firmly clockwise to lock them together.
Sheet metal screws are not
required, but they may be used to
reinforce the connection, if desired.
Use only 1/2″ (or shorter) sheet
metal screws. Do not penetrate the
inner liner of the chimney.
8. Install Attic Insulation Shield:
Install the Attic Insulation Shield
where the chimney passes into an
attic. It’s purpose is to prevent
debris and insulation from getting
too close to the chimney (Fig 10).
An installed Attic Insulation Shield
is 15 inches high. In attic areas
where this shield cannot fit, you
must enclose the attic portion of the
chimney in a framed enclosure. If
thechimneyisfullyenclosedthrough
the attic, an Attic Insulation Shield
is not required. If the chimney
passes into the attic, install the Attic
Insulation Shield as follows:
a. If the Firestop Radiation Shield
extends above the attic floor, no
modifications are necessary. The
Table 2
9
Firestop Radiation Shield will fit inside the Attic Insulation
Shield.
b. Assemble Chimney Sections until at least 18 inches of
chimney extends above the Firestop Radiation Shield.
c. Extend the Firestop Radiation Shield tube extension
(keep at least 1″ overlap), and secure in place using sheet
metal screws.
d. Slip the Attic Insulation Shield over the Chimney and
Firestop Radiation Shield until the base sits squarely on
the framed opening (Fig 7 & 10).
e. Secure the Attic Insulation Shield to the top of the
framed opening using at least (3) 8-penny nails or (3) #8, 1-1/2″ wood screws per
side (Fig 10).
f. Wrap the Collar of the Attic Insulation Shield around the chimney and fasten
it loosely. Slide the Collar down to meet the Attic Insulation Shield. Slip the tab
through the adjacent slot and fold it back to tighten and secure the Collar (Fig 11).
9. Attach Flashing: In new construction, assemble the Chimney Sections to a
point above the roof, then slip the Flashing over the chimney. On an existing roof,
center and install the Flashing before extending the chimney above the roof. Allow
space to permit sliding the next Chimney Section up through the Flashing. Always
insure the chimney remains vertical (use level), and that at least a 2-inch clearance
to combustible materials is maintained all around. Install the upper edge of the
Flashing under the roofing. Nail to the roof along the upper edge and down each
side with 1-inch roofing nails. Do not nail the lower edge of the Flashing (Fig 12).
Be sure to follow local building practices, as needed. Seal all nail heads with a nonhardening
waterproof sealant. On flat or tarred and graveled roofs, nail and seal
the Flat Roof Flashing to the roof on all sides with roofing compound. Do not put
screws through the Flashing into the Chimney Pipe.
10. Finish Top: Apply a high-temperature (500OF), non-hardening waterproof

sealant around the chimney at the point where the Storm
Collar will meet the chimney just above the Flashing.
(Figures 12 and 13). Slide the Storm Collar down over the
chimney to the top of the Flashing. Tighten and seal the
Storm Collar against the sealant. After installing sufficient
Chimney Sections to meet the height requirement (Fig 1),
attach the Chimney Cap onto the top of the chimney by
holding the collar of the cap and twist locking it clockwise
onto the chimney. Do not hold upper portion of the cap and twist, as this may
damage the cap. The Chimney Cap can be removed for chimney cleaning as
described in the Chimney Maintenance section of the instructions. Use an Extended
Roof Bracket if the chimney extends more than 5 feet above the roof. (Figures 16
& 17 in the Extended Roof Bracket section). If you are located in heavy snow
country, it is recommended that a “splitter” be installed, and should be fabricated
from heavy gauge sheet metal (Fig 14). This will protect the chimney by routing the
snow around it. This item is not furnished by Simpson Dura-Vent.
11. Enclosures: Enclose chimneys where they pass through occupied spaces,
including closets. Always maintain at least a 2 inch clearance between the chimney
and any combustible materials. Interior enclosures may be constructed with
standard framing and sheathed with sheetrock or plywood. Use Wall Straps as
needed to maintain a minimum of 2 inches of air space between the chimney and
combustible materials.
OFFSET ELBOW INSTALLATION
Elbows are manufactured in 15° and 30° angles measured from the vertical. A 30°
Elbow is the largest that can be used in an offset. A 30° Elbow may not be combined
with a 15° Elbow to make a 45° offset. Avoid Elbows if possible, since a totally
vertical chimney is more efficient. When Elbows are necessary to avoid obstructions
such as rafters, ridgepoles, or joists, use no more than 2 pairs of Elbows in any
one chimney system.

1. Attach Elbows: Attach Elbow to Chimney
Section or other Elbow by twisting clockwise until
they lock firmly. Attach one Elbow to the Chimney
Section below, and align it for the offset. Elbows for
DuraTech have a swivel feature that allow for 360O
rotation for ease of installation. Refer to Table 3 to
determine the required offset length and attach an
appropriate length (or lengths) of Chimney
Section(s) above the Elbow. The maximum length
of chimney pipe between elbows is not to exceed
72″ (maximum of two chimney sections only).
Attach the second Elbow above the Chimney Section
to complete the offset (Fig 15).
2. Secure Offset: Place the Elbow Strap’s band around the angled portion of the
top Elbow, then tighten the nut and bolt until the clamp is firm. Wrap the Elbow
Strap end over an adjacent joist or rafter and secure it with at least (2) 8-penny nails
or (2) #8, 1-1/2 screws. Do not add more Chimney Sections until the Elbows are
supported. Be sure that the chimney remains vertical. If there is more than one
Chimney Section between the Elbows, install a second Elbow Strap around the
joint of the two Chimney Sections (Fig 15).
EXTENDED ROOF BRACKET INSTALLATION
If the chimney extends more than 5 feet above the roofline, an Extended Roof
SPLITTER
SPLITTER
TOP
VIEW
12
Bracket must be installed at every 5-foot increment
of chimney height above the roofline,
leaving no more than 5 feet of chimney extending
above the last pipe bracket. The Extended
Roof Bracket consists of the Pipe Band, the
Adjustable Legs, and the Roof Brackets.
1. Mount Pipe Band: Slip the Pipe Band
around the chimney and secure by tightening
the nut and bolt.
2. Attach the Legs: The Adjustable Legs of
the assembly will adjust from 67″ to 114″.
Secure one end of the Legs to the Pipe Band
using the nuts and bolts included (1 per Leg).
Position the Adjustable legs so they form approximately
a 60° angle with the chimney, and
with each other (Figures 16 and 17). Be sure
that there is at least 3″ of overlap between the
top and bottom halves of the Adjustable Leg.
In order to secure Legs in proper position,
there is a hole provided in the outer leg where
the outer and inner halves overlap. Use a 1/4″
drill bit to drill through the inner leg at that
location. Use the nut & bolt provided to pin the
Adjustable Legs in position.
3. Install Roof Brackets: Mount the two Roof Brackets where each of the
Adjustable Legs meets the roof, using (6) 1″ roofing nails per bracket. Seal the nail
heads carefully with a non-hardening, waterproof sealant. Attach the bottom end
of the Adjustable Legs to the Roof Brackets using the nuts & bolts provided.
ROOF SUPPORTED INSTALLATIONS
There are two types of Roof Supported Installations: (1) Using a Square Ceiling
Support Box, and (2) Using a Roof Support.
(1) For a Square Ceiling Support Box installation, make sure that the square box
portion of the Support Box can extend at least 2″ below the low side of the finished
ceiling (Fig 19). The Support Box must remain level, and the top edge of the box
must cover the edge of the roof’s decking material. Square Ceiling Support Boxes
are available in 11-inch, 24-inch, and 36-inch heights. Mobile home chimney
TABLE 3

installations are roof supported. Do not seal openings in flashing.
1. Place Appliance: Place the appliance in its proper location, referring to the
manufacturer’s instructions as to allowable distances from combustibles, etc.
2. Cut Openings: Cut a roof opening in your desired location, just as in a Ceiling-
Supported Installation (Steps 1 through 5, page 5). If a separate ceiling and roof
exists, as shown in Figure 18 (Low Attic), first cut and frame a ceiling opening as
described in Ceiling-Supported Installations (Step 2). Refer to Table 2 for
clearance and framing specifications. If it is desired to install through a cathedral
ceiling (Fig 19), then the hole is cut in the roof.
3. Install Support Box: Slip the Square Support Box into the framed opening so
the square portion projects at least 2 inches below the finished ceiling and rafters
(bottom of round portion is 5″ below), and extends above the ceiling to framing or
decking materials that it can be nailed to. Level the Support Box, and slit the
corners to the roofline where they extend beyond it. Bend the flaps (created by the
slitting) flush with the roof, and nail the Support Box to the roof or framing with at
least three (3) 8-penny nails, or (3) 1-1/2″, #8 screws, per side (Fig 20). Be sure
to keep the Support Box level. Screw the trim sections into the ceiling (Fig 6).
4. Complete Installation: Refer to Steps 7, 9 & 10 in the Ceiling Supported
Installation section to complete the Roof Supported installation.
(2) A Roof Support is also used in installations where there is a cathedral ceiling,
and a Square Ceiling Support is not desired. The Roof Support allows the
DuraTech chimney to come down into the room below the level of the ceiling (Fig
21). The Roof Support can support a maximum of 45 feet of DuraTech Chimney
total, and maximum of 20 feet below the support. If a taller stack of DuraTech
Chimney is required, you must use a Square Ceiling Support Box instead.

1. Cut and frame opening to provide a minimum 2″
clearance on all sides of the chimney pipe. Note:
Opening in finished ceiling should be circular/oval in
order for it to be covered by Trim Collar.
2. Bolt on the Roof Support Brackets to the Roof
Support Band using the supplied hardware. Attach
the Roof Support Brackets to roof using (4) 8 penny
nails or (4) #8, 1-1/2″ screws per side (Fig 21).
3. Determine how much DuraTech Chimney will be extending into the room
(minimum of 3″ below the ceiling). Be sure to maintain the proper clearance to
combustibles (walls and ceilings) for the connector pipe. Once you have identified
the proper height for your installation, attach the of the Roof Support Band to the
Chimney Section by tightening the Bolt, and secure it by using (4) supplied sheet
metal screws.
4. Attach desired length of Chimney Sections above and below the roof level (max.
of 45′ total, 20′ below the support). To transition to the Connector Pipe, attach the
Finishing Collar by twist locking it to the bottom section of DuraTech Chimney.
5. Slide Trim Collar over the DuraTech Chimney and attach the Trim Collar to the
ceiling using (4) 1-1/4″ screws provided (Fig 21).
6. Refer to Steps 10 & 11 in the Ceiling Supported Installation section (page 9)
to complete the Roof Supported installation.

basement installations. Maintain a minimum
of 2” clearance to combustibles at
all times. The DuraTech Chimney needs
to extend a minimum of 3” below the finished
ceiling or exposed framing members.
Please note that you cannot extend the
chimney all the way to the appliance – you
must have some connector pipe.
1. Cut and frame opening to provide a
minimum of 2″ clearance on all sides of the
chimney. Be sure to maintain the proper
clearance to combustibles for the
connector pipe.
2. Bolt on the Roof Support Brackets to
the Roof Support Band using the supplied hardware. Attach the Roof Support
Brackets to floor using (4) 8 penny nails or (4) #8, 1-1/2″ screws per side (Fig 22).
3. Determine how much DuraTech Chimney will be extending into the room
(minimum of 3″ below the framing), and attach the of the Roof Support Band to the
Chimney Section by tightening the Bolt, and secure it by using (4) supplied sheet
metal screws (Fig 21 & 22).
4. Install the specialized Firestop below the finished ceiling or framing members.
The Firestop can only be used when installed with the Roof Support in this type of
installation. Use a standard Firestop Radiation Shield at all other locations.
5. Follow steps 4, 5 & 6 for the Roof Support Installation (page 15).
TEE-SUPPORTED INSTALLATIONS
Tee-Supported installations are used when passing through a wall to an outside
chimney. The Tee Support can hold a maximum of 60 feet of DuraTech Chimney.
The Tee Support and Wall Straps are adjustable, allowing from 2″ – 6″ of clearance
between the chimney and the wall, as needed to fit your installation. There are two
options when installing a Tee-Supported installation: the Tee Support above the
Tee, or the Tee Support below the Tee. The required parts and general
configuration are as shown in Figures 23, 24, 25 and 26.
1. Place Appliance: Position the appliance according to the manufacturer’s
instructions. It is a good idea to try to position the appliance so it will allow the
chimney to line up centered between studs.
2. Locate, Cut & Frame Opening: Determine the location where the chimney

will pass through the wall. The chimney
should pass through the wall, centered
between two studs. The height of the
penetration can be determined by positioning
sections of stove pipe until you have the
desired configuration (refer to the appliance
manufacturer’s installation instructions for
restrictions on stove pipe). Cut and frame an
opening in the inner and outer walls at this
location. Refer to Table 2 (page for the
appropriate framing dimensions.
3. Install Wall Thimble: The Wall Thimble
is a three piece unit which includes the cover
plate, sleeve extension, and the back portion
with shield. On the outside wall, install the
back portion of the Wall Thimble. Center the back portion of the Wall Thimble
(with shield inside wall) in the framed opening of the outside wall. Be sure to seal
the flange of the Wall Thimble around the wall by using a non-hardening waterproof
sealant. Attach the back portion of the Wall Thimble to the outside wall using at least
(4) 8-penny nails or (4) #8, 1-1/2″ wood screws. Depending on the thickness of
your wall, you will need to adjust the shield extension to insure that you have a
continuous shield throughout the wall penetration. You may field-fabricate a longer
extension tube if needed. Adjustments can be made by sliding the extension in or
out of the back portion of the shield. Verify that the shield extension reaches the

that Tee is centered through Wall Thimble
(Fig 25 & 26). Use the 1/2″ sheet metal
screws provided to insure a tight connection
between support band and chimney
section. Connect support band to support
base using the 1/2″ sheet metal screws
provided (Fig 26). Twist lock Tee Cap
into bottom of Chimney Cleanout section.
6. Install Branch onto Tee: From inside
the house, attach the Chimney Branch (a
12″ or 18″ Chimney section, depending on
wall thickness, positioned horizontally used
to pass through the wall) to the Tee by twist
locking it clockwise. Important: The Chimney section used to penetrate through the
wall must extend at least 6″ into the room (Fig 25 & 27). Use high-temperature
sealant (500OF) to seal between the Wall Thimble and the Chimney on the outer
wall.
7. Install Cover Plate and Finishing Collar: After the Chimney Branch is
secured in place (penetrating at least 6″ into the room), slide the Cover Plate over
the Branch and attach it to the framing using (4) 1-1/4″ long, round head wood
screws. Be sure that the Branch is centered in the opening of the Cover Plate. Twist
lock the Finishing Collar on to the female end of the Chimney Branch by twisting
clockwise.
8. Complete Chimney: Attach the Chimney Sections as in Step 7 in the Ceiling
Supported Installation section (page 8). Secure the chimney to the wall with Wall
Straps at a minimum of 8-foot intervals and maintain at least 2 inches of clearance
to combustible materials. The Wall Straps are adjustable to allow from 2″- 6″
clearance to combustibles. Slip the Wall Straps around the chimney, tighten the
bolts, adjust the clearance, and fasten the Wall Straps to the wall with (4) #8, 1-

1/2″ long wood screws. Once the chimney is at the minimum height specified in
Figure 1, attach the Chimney Cap onto the top of the chimney by holding it by the
collar and twist locking it clockwise onto the Chimney Pipe. If the chimney
penetrates an overhang, frame for at least 2 inches of clearance, and install Flashing
and Storm Collar as described in Steps 9 & 10 for Ceiling Supported Installations
(page 9). Another option is to cut away the overhang for a 2-inch clearance (Fig
28). If the chimney extends more than 5 feet above the top Wall Strap or Flashing,
use an Extended Roof Support Bracket (See page 11).
9. Install Chase Top Flashing: It is recommended that a Tee Supported
Chimney be enclosed in a chase. If a chase enclosure has been constructed, you
can either use a standard flat-roof flashing, or you can use a Chase Top Flashing.
Using a Chase Top Flashing allows for a lower profile for the chimney. The Chase
Top Flashing has an opening that is 3″ larger in diameter than the DuraTech
Chimney. If the Chase Top Flashing can fit over your chase enclosure as required
(Fig 29) then install as directed, or trim as needed. However, if the Chase Top
Flashing is smaller than your chase enclosure, you will need to provide a galvanized
sheet capable of covering your chase and overhanging the sides by 1/2 – 3/4 inch.
Attach the Chase Top Flashing to the galvanized sheet using appropriate sheet metal
screws and non-hardening waterproof sealant. Use the Chase Top Flashing
Spacers to allow the proper air-gap clearances
on the galvanized sheet. The Chase Top Flashing
Spacers are available to insure that the

proper air-gap is maintained. Figure 29 displays in some detail, how these air gaps
are established using the Spacers and Chase Top Flashing. Secure the Chase Top
Flashing to the chase using a sufficient number of #8, 1-1/2″ wood screws, being
careful to insure the air gap is maintained between the flashing and the chase. Seal
the screw heads with non-hardening sealant. When installing the Storm Collar,
allow a 1″ air space between the bottom of the Storm Collar and the Chase Top
Flashing .
MASONRY FIREPLACE INSTALLATIONS
1. Determine Chimney Size: Use Table 4 to determine the correct diameter
chimney for your fireplace.
2. Mount Anchor Plate: Chimneys for masonry fireplaces begin with an Anchor
Plate. Make sure the surface of the masonry chimney has a level surface on which
to attach the Anchor Plate. If the top of the masonry does not have a level surface,
then you will need to modify the masonry accordingly. Center the Anchor Plate over
the masonry flue opening, and seal the Anchor Plate with a high-temperature
(1000OF) sealant. Secure Anchor Plate with (4) 1/4″ x 2″ masonry anchors (Fig
30). It is very important that the Anchor Plate is level. Be sure to maintain a 1″ min.
clearance to combustibles from the Anchor Plate.
3. Attach Chimney: Twist lock the first Chimney Section clockwise onto the
Anchor Plate.

Table 4 for chimney height requirements. Always maintain at least 2 inches of
clearance to combustible materials, and enclose the chimney where it passes
through occupied areas. Use a Wall Strap for every eight (8) feet of chimney height.
ZERO-CLEARANCE FIREPLACE INSTALLATIONS
1. Manufacturer’s Instructions: Carefully read and comply with the
manufacturer’s installation instructions for your fireplace. Be sure that DuraTech
is approved for use with your appliance.
2. Anchor Plate: Attach an Anchor Plate to the fireplace top with (4) 5/8″ sheet
metal screws (Fig 31). Check with the appliance manufacture about the use of high
temperature sealants.
3. Chimney Sections: Attach a Chimney Section to the Anchor Plate by twistlocking
clockwise.
4. Completion: Install the remainder of the chimney as instructed for a standard
Ceiling-Supported installation, (using a Firestop Radiation Shield in the 1st
floor ceiling instead of the Support Box). Always maintain at least 2 inches of
clearance to combustibles, and enclose the chimney where it passes through
occupied areas.
CONNECTION FROM APPLIANCE TO CHIMNEY SYSTEM
1. Single Wall Stovepipe: If single wall stovepipe is desired, Simpson Dura-
Vent’s “Dura-Black” single-wall stovepipe is recommended. The connection to
the Ceiling Support Box, or Finishing Collar is made with a Dura-Black Slip
Connector or a Snap-Lock Adapter. The beaded end of the Slip Connector or

Align the tabs on the Slip Connector or Snap Lock Adapter with the notches in the
face of the Support Box or Finishing Collar, push it in and rotate to lock it in place.
Further instructions for assembling Dura-Black Stovepipe are contained in their
shipping cartons. Remember, the minimum clearance to combustibles for single
wall stovepipe is 18 inches.
2. Close Clearance Connector Pipe (DVL): Simpson Dura-Vent manufactures
a close clearance connector pipe, also referred to as “DVL”. DVL may be
positioned as close as 6 inches to a combustible wall, and as close as 8 inches to
a combustible ceiling, provided the appliance installation instructions permit this
distance. In order to join this type of connector to the Support Box or Finishing
Collar, a DVL Adapter is required. The DVL Adapter slips into the opening in the
Support Box or Finishing Collar. Align the tabs on the DVL Adapter with the slots
cut into the face of the Support Box or Finishing Collar, and push it in, and rotate
to lock it in place. Detailed instructions for assembling the remainder of the close
clearance system are included in the DVL shipping cartons.
3. Connection to Oil-Burning Appliance: DVL is especially recommended for
oil appliances because of the corrosive nature of oil-burning exhaust. When
connecting to an oil burning appliance, refer to National Fire Protection
Association Standard #211. Table 6-5.1.1 in NFPA 211 states that you must
allow for 18″ clearance to combustibles if you are using single wall vent
connector. If , however, your appliance is Type-L Vent listed and you are using
a listed Type-L Vent connector, then you are permitted to use the clearances as
specified by the vent listing.
CHIMNEY MAINTENANCE
1. Creosote and Soot: When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture to produce creosote.
The creosote vapors condense in the relatively cool chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire.
2. Access: Chimneys must be installed so that access is provided for inspection
and cleaning.
3. When to Clean: The chimney should be inspected at least once every month
during the heating season to determine if creosote or soot has built up. Check spark
arrestor screens at least every 2 to 4 weeks. If creosote or soot has accumulated,
it should be cleaned or replaced to reduce the risk of chimney fire.

4. How to Clean: Have your chimney cleaned by a professional chimney sweep
if you have doubts about your ability to clean it. Use a plastic, wood, or steel brush.
Do not use a brush that will scratch the stainless steel liner of your chimney. Scrub
the spark arrestor with a wire brush. To remove the Chimney Cap for cleaning,
either twist counter-clockwise to remove the entire cap, or unscrew the four (4)
screws that attach the cap’s support legs to the cap base. The Tee Cleanout Cap
can be removed by turning counter-clockwise. Be sure to replace Tee Cleanout
Cap when you are finished cleaning the chimney.
5. Coal: To reduce corrosion in chimneys where coal is burned, clean the chimney
thoroughly within 48 hours of shutting down the stove for the season.
6. Chemical Cleaners: Use chemical cleaners only as a last resort, and use only
those which the manufacturer specifically warrants as being noncorrosive to the
chimney liner. Simpson Dura-Vent will assume no liability for damage resulting from
the use of chemical cleaners.
7. In Case of Fire: If a flue fire occurs, close all appliance air inlets, and call your
Fire Department. Do not use the chimney again, until it has been inspected for
possible damage.
8. Painting: As an option, you can coat all exterior metal parts, with the exception
of the Chimney Cap, with high temperature, rust proof paint. Wash the metal with
a vinegar and water solution before painting. Painting the chimney will help to
increase chimney life.
9. Creosote Formation: Simpson Dura-Vent assumes no liability for any
structural damage or roof contamination as the result of creosote formation. It is
the owner’s responsibility to comply with inspection and cleaning requirements as
described in these instructions, and those of the appliance manufacturer.
10. Warranty: Simpson Dura-Vent proudly offers a limited lifetime warranty on
DuraTech Chimney components. The warranty includes all components except
chimney caps, which are warranted for 5 years. For specific details, refer to the
printed warranty included in the Chimney Product Catalog. Dura-Vent, DuraTech
Chimney, DVL, Close Clearance Connector, and Dura-Black are the registered

YOUR HOME IS PROBABLY YOUR BIGGEST
INVESTMENT, BUT DID YOU KNOW YOU CAN MAKE
AN INVESTMENT IN YOUR HOME THAT WILL PAY YOU
BACK WITH ENERGY SAVINGS? It’s photovoltaic power
— solar electric energy — and it harnesses the power of
sunlight to supply your home with electricity. Simply put,
photovoltaic (PV) systems produce electricity from sunlight
through cells that are installed on your roof or elsewhere
on your property. PV power doesn’t produce any noise or
pollution, it’s reliable and dependable, and it’s renewable
so it makes good sense for the environment. For example,
a 2.5 kW system will provide about 2,900 kilowatt hours
per year and can typically provide about 25 to 35% of an
average home’s electricity needs. The more energy efficient
your house is, the greater the impact of the PV system.
Power NaturallySM SM
Not only is photovoltaic power
GENTLER ON THE ENVIRONMENT, it is now
MORE AFFORDABLE than ever before.
This is because New York State is offering cash incentives to bring
down the cost of PV systems by 40 to 70%. These incentives from
NYSERDA — New York State Energy Research and Development
Authority — are available to all customers that pay the Systems
Benefit Charge to their electric utility. Working with an eligible
installer, you could receive between $4,000 and $5,000 per kilowatt
for PV systems up to a maximum of 15 kilowatts. The chart below
outlines the different incentive levels NYSERDA is now offering.

In order to help you get started, we’ve put together this comprehensive
guide, which contains essential information on PV power, including how to
choose an installer, select a PV system, and calculate your potential energy
savings. It’s not a technical installation guide — your PV installer will
handle those issues — but it will explain how PV works and help you decide
if it’s right for you.

step 1
PV BASICS
PV technology converts sunlight directly into electricity throughout the day,
allowing you to produce your own electricity with no noise, air pollution, or
moving parts. The basic building block is the PV cell, which is connected to other
cells to create larger units called modules. Typically, modules are attached as
panels onto your existing roof or are designed directly into the roof so they act as
both a part of the roof or shingles and a solar module at the same time. The
integrated roofing option may make sense if you are building a new home or
considering replacing your current roof. Modules can also be set up as
freestanding units on the ground.
A PV system includes a collection of PV modules
that is usually connected to the utility grid. Systems
must be connected to the utility grid to be eligible
for the cash incentive offered by NYSERDA. The PV
modules produce direct current (DC) electricity, which
the system then converts to alternating current (AC)
electricity so it can be used to power your lights,
appliances, and other home electrical needs. Being
connected to the utility grid provides two additional
benefits. First, when your system doesn’t produce
enough electricity to power your home (when the sun
isn’t shining, for example), you automatically receive
the additional power you need from the utility. Second,
if you produce more electricity than you need — which
can happen on most sunny days — electricity flows
back through your meter to the utility. In fact, your
meter will run in reverse when your PV system
is producing more electricity than you need, and
you can receive a credit from the utility for the energy
you’re supplying but don’t use. (See Step 6 for more
information).
A good way to think of it is that purchasing a PV system is like paying for many years’
worth of electricity at once, since the cost is in the up-front purchase. Once your system
is installed there should be minimal maintenance. With the NYSERDA incentive program,
the cost of purchasing and installing a system is reduced by about half, but you’ll want
to examine your personal energy use and savings closely before choosing a PV system.
We’ll look at these issues in more detail later in this guide.

AND NUMBER OF
MODULES YOU USE.

If you’re building a new home, you can enjoy even greater savings when you participate
in New York’s ENERGY STAR® Labeled Homes program. These homes use 30% less energy
than conventionally built homes by incorporating the best construction practices and energysaving
measures into your home. New York’s ENERGY STAR® homes are also eligible for a
PV incentive level that is $500 per kW higher than a regular home built to code.

CONDUCTING YOUR OWN SITE SURVEY
The amount of electricity generated by a PV system depends on
a number of different factors, and the first step is to look at your
own home. The reason for this is quite simple: the amount of
electricity you produce is determined by how much sun
reaches your system. You’ll want to look at a few basic areas
to make sure your house is well suited for a PV system and that
you maximize the energy your system produces by placing it in
the most advantageous location.
1.
2.
3.
The first question to ask yourself is whether your property has good
access to the sun. In New York, the sun is in the southern half of the
sky and is higher in summer and lower in winter. This means the best
location for a PV system is typically a south-facing roof, but east and
west may be fine as well.
You’ll also want to look for objects such as trees, vent pipes on your
roofs, chimneys, or buildings that could block or obstruct the sun
from reaching your system. You’ll want to determine how large the
obstruction is and how long it casts a shadow onto your roof or other
proposed PV system site. Your PV installer will have special tools to
help measure shading.
If you think there are potential trouble areas, then it’s a good idea to
use the Clean Power Estimator available at www.PowerNaturally.org
to conduct a more thorough examination. Your PV installer can also
assist with this analysis.
If all obstructions to the east and west of your PV array
are more than two times the distance from the system
as they are high, and obstructions south of the PV
system are more than three times the distance from
the system as they are high, then your PV system
should have no more than 10% loss due to shading.
A GOOD RULE OF THUMB:
step 3
CHOOSING AN INSTALLER
Your PV installer not only sells and sets up your system, he or she also ensures that
you get the system that is right for your home and your energy needs. By working
closely with your installer, you can identify any potential trouble spots and come up
with solutions so you get the most out of your PV system. Ultimately, it means your
system will run more efficiently and produce the optimal amount of energy.
Based on these conversations, you should solicit price quotes from at least three installers.
The quotes should include a clear outline of how much your system can produce at its
capacity rating, as well as estimated annual energy generation. Energy generation will
fluctuate from year to year due to changes in the amount of sunlight, so you should
remember that your actual system output may be higher or lower than the estimate.
Of course, the quote should include details on the “fully loaded” cost of getting the PV system
up and running, including hardware and installation costs, connection to the electric grid,
permitting, applicable incentives, and warranties. Lastly, remember that you’ll be working
with your PV installer for several months, so choose one you think you can work with closely.
* Neither NYSERDA nor the State of New York: (1) endorse any Eligible Installer; or (2) guaranty, warranty, or in any way represent or
assume liability for any work proposed or carried out by an Eligible Installer. Additionally, NYSERDA is not responsible for assuring that the
design, engineering and construction of the project or installation of any photovoltaic (PV) system is proper or complies with any particular
laws, regulations, codes, licensing, certification and permit requirements, or industry standards. NYSERDA does not make any
representations of any kind regarding the results to be achieved by the PV systems or the adequacy or safety of such measures.
To help you get started, take a look at the list of eligible
installers at www.PowerNaturally.org. These PV installers
are part of the NYSERDA incentive program, so they’ll be
offering you cash incentives for PV system sales and
installation. Each eligible installer who has applied for and
been accepted as part of the program provides evidence of
his or her skills, experience, and customer track record.*
And as NYSERDA incentive participants, every eligible
installer is offering a minimum five-year warranty that
covers full costs, including labor, and repair or replacement
of components or systems.
Once you’ve reviewed the list, you’ll want to narrow it
down by calling several different installers and asking
them about their experience and working practices. One
of the first considerations may be their location, since it may
be easier and less expensive if they are located close to you.
ONE OF THE MOST IMPORTANT PV DECISIONS YOU’LL MAKE IS
CHOOSING AN INSTALLER.
OTHER QUESTIONS TO CONSIDER:
Have they installed gridconnected
systems before?
How many years have they
been in business?
What is their process and
timing for installing a system
from initial site visit through
completion?
WHAT IS A CERTIFIED INSTALLER?
The North American Board of Certified Energy
Practitioners(NABCEP) has developed a national
voluntary certification program for PV installers.
Ask your installer if they are certified by NABCEP
or pursuing NABCEP certification. www.nabcep.org
UNDERSTANDING YOUR SYSTEM OPTIONS
There are several different options when it comes to choosing a system. Most PV
systems produce about 10 watts of power for each square foot of PV module. This means that
you can install a small starter system on as little as 50 square feet of roof space, or as large
as 1,000 square feet for a more powerful system. A typical two kilowatt system will need 200
to 400 square feet of unobstructed area, but always make sure you’re able to access your
system easily. This access space can add up to 20% to the total space you need for your
system.
A PV array can be built onto any type of roof, but the installation cost can vary
based on the type of roofing material. For example, composition-shingle roofs are quite
easy to work with, while slate roofs are much more difficult. Your PV installer should be
able to work with all roof types and should discuss any problem areas with you. One
area that you’ll want to look at quite closely is the age and condition of your roof. If your
roof is old and will need to be replaced soon, you may want to consider replacing the roof
and installing the PV system at the same time. This will eliminate having to take down
the PV system and reinstall it in the future.
No matter how large — or
how small — your system is,
you’ll need to decide where
to locate it. The most common
choice is to position the modules
on your roof. The system, or
array, can be mounted above
and parallel to the roof with a
space between the roof and the
array to allow for cooling. The
modules are typically positioned
parallel to the roof so that they
blend in as much as possible.
If, however, your roof is flat,
a PV array may be installed
at an angle to optimize the
amount of sunlight it receives.
step 4
A roof-integrated PV system with solar hot water collectors on the left.
NO MATTER WHAT THE SYSTEM,
YOU CAN CHOOSE ONE WITH
BATTERY BACKUP OR ONE
WITHOUT. A battery backup system
stores energy so your home can be
powered when the sun isn’t shining
(really cloudy day), at night, or during
a utility outage. The amount of
energy your battery system can
provide will depend on the storage
capacity of your system. Systems
with battery backup are more
expensive, however the incremental
investment is worth considering if
you want to have power for critical
loads during outages and the added
reliability is important to you.
If your roof isn’t made of composition shingles, then it will most likely
require a flashed penetration to ensure that it’s properly sealed against
rainwater. Make sure that your PV installer offers a written guarantee that
the roof will not leak as a result of the PV system for at least five years.
A GOOD RULE OF THUMB:
If you are considering a new roof or are
building a new home, you should investigate
a roof-integrated system – Building-Integrated
PV Array, or BIPV. This option incorporates the
PV modules into the actual roofing material, so
the roof acts as the solar collector. BIPV’s are
available as roofing shingles or metal roofing
products and are great because they’re designed
to look like traditional roofing materials. You
do need to take extra care to make sure they’re
installed properly, so be sure to discuss
this with your installer.
Lastly, you can install the array for your PV
system as a ground-mounted structure, or you
can even mount the array off the ground as a
shade or patio cover.

step 5
DETERMINING ENERGY OUTPUT AND SAVINGS
One of the most important questions you’ll have when you’re considering
PV power is how much your system will cost and how much it will save
you. A good place to start is to understand how much electricity you currently
use. You can do this by looking at your electricity bills for the past year or by
contacting your utility. This will give you a baseline so you know how much
electric energy you’re using now and how much you’ll be able to offset by
installing a PV system.
Your energy savings with a PV system can be estimated by multiplying the energy
in kilowatt-hours (kWh) that your system might produce each year by the electric
energy rate charged by your utility. The chart below shows the estimated annual
energy savings from a small (2 kW) and a large (4 kW) system to illustrate a range
of savings based on four different electric rates.
To get a better idea of
your own savings, use the
Clean Power Estimator at
With the Clean Power Estimator
you’ll be able to run several in-depth
analyses with your own details so
you can see if solar electric power
makes financial sense for you. The

Syracuse 1035-1279
Binghamton 1017-1256
Poughkeepsie 1116-1379
If you’re installing a roof-mounted system, the tilt and orientation of your roof
will affect your system’s output. For example, in New York State, a 30-degree
roof tilt facing south produces the greatest output, while an east-facing roof
with the same tilt will generate 19% less electricity.
A GOOD RULE OF THUMB:
The larger the system, the more
electricity you’ll be able to generate,
but at a higher up-front cost. You
should consider four factors when
choosing a system: your energy
needs, the amount of the energy
you can generate, whether you
want a battery backup system, and
the system costs. What you should
remember is that no matter what
system you choose, the actual output
will vary due to environmental and
system fluctuations. The adjacent
chart is designed to give you a
conservative estimate of the amount
of power generated by a one-kilowatt
(1kW) system. Ask your PV provider
how much electricity your system
will produce each year and how that
compares with the amount of
electricity you typically use each year.
THE QUESTION WILL THEN BE HOW LARGE A SYSTEM YOU WANT TO INSTALL.
step 6
OBTAINING PERMITS AND APPROVALS
If you have a PV system installed, you’ll need to make sure you have the
proper permits and approvals before you begin work. Your installer should be
able to handle most of these details, but you should be familiar with them as well
to make sure you have everything you need.
CODES, COVENANTS, AND RESTRICTIONS
Often called CC&Rs, these are requirements imposed by neighborhoods
or local jurisdictions that often govern the aesthetics of a project.
If CC&Rs are in place in your area, you may need to submit plans
and obtain approval before you can begin work. Check with your
neighborhood association or town council to find out if there are
any applicable CC&Rs.
ELECTRICAL AND STRUCTURAL PERMITS
The most common permit you’ll need for your PV system is an electrical
permit. Photovoltaic systems are included in the National Electrical Code
in Article 690. Your installer should be familiar with this and ensure you
have the proper permit before work commences.
Also, you should determine if you’ll need a structural permit as well.
Normally, structural permits are issued if it is deemed that the project
will have a significant impact on an existing structure or involve a new
structure that could put people or property at risk if the structure
collapsed.
A GOOD RULE OF THUMB:
If your home is less than 30 years old, it should not
need structural enhancements as long as the PV
system weighs less than five pounds, per square foot.
Most PV systems meet this weight restriction. However,
if you have two layers of shingles on your roof, you
must remove both layers and install new shingles
before you install a system.
• In order to be connected to the grid, you and your installer will need to
complete a contract with the utility. This contract includes important system
information and shows that you understand your responsibilities in running
and maintaining your system. Normally, the contract will be finalized once
the utility confirms that the equipment has been installed properly and that
all requirements have been met.
• One requirement of the interconnection agreement is that you have a
minimum level of insurance in place. This should be covered by your
current homeowner’s insurance policy, but make sure your current
coverage is sufficient to meet the interconnection requirements.
• You will also need to complete a net metering agreement
with the utility for residential systems of 10kW or less.
Interconnecting a photovoltaic system to the utility grid
requires an interconnection agreement as well as a sale
and purchase agreement, or a net metering agreement
with your local utility. Your PV installer and utility
company will be able to go through this with you in
more detail.
UTILITY INTERCONNECTION
STANDARDS AND CONTRACTS
In order to be connected to the utility grid,
you must follow interconnection standards
as set out in Institute of Electrical and
Electronic Engineers (IEEE) 929-2000
(www.ieee.org) and New York State
Public Service Commission’s Standard
Interconnection Requirements
(www.dps.state.ny.us/distgn.html).
It is vital that you inform your utility
as early as possible that you will be
installing a grid-connected PV system
and adhere to their rules exactly. Your
PV installer should be familiar with
entering into an interconnection
agreement with your utility.
PERFORMANCE EVALUATION
Once your system is installed, your PV installer will run a series of
tests to make sure your system is up and running properly. Make sure
you receive a copy of this evaluation, and keep it as part of your system
documentation. Other vital documents to keep with this are your owner’s
manual, copies of any plan drawings, and instructions for any future
maintenance.
UTILITY AND INSPECTION SIGN-OFFS
After your system is installed, it must be inspected by the local
permitting agency (typically this is a building and/or electrical inspector).
Most likely, your system will be inspected by the utility as well. These
inspections may identify problem areas that need to be corrected, so
don’t be alarmed — this is fairly common and your PV installer can
deal with most issues easily. Additionally, NYSERDA may inspect systems
that have been installed through any of its incentive programs.
SYSTEM MAINTENANCE AND MONITORING
PV systems require very little maintenance, but you should discuss
this with your installer and review any recommended maintenance
procedures. One of the easiest ways to check your system’s performance
is to monitor your own electricity meter. This will give you an idea of
how much electricity you are using and if your PV system is performing
properly. Through the NYSERDA program, your system will include an
easy-to-read digital meter that can help you monitor real-power output
and energy production.
WARRANTIES
All PV installers operating under the NYSERDA incentive program
will provide you with a full five-year guarantee that covers full costs,
including labor, and repair or replacement of components or systems.
Some installers may offer additional warranties, and you should discuss
this with them in detail to make sure you understand what they cover
in case a problem arises.

How to Build and Install a Rain Barrel
STEP 2. Set Up Barrel and Modify Downspout
! Set up barrel
Since water will only flow from the garden hose when the hose is below the barrel, place the barrel on
high ground or up on cinder blocks or a sturdy wooden crate underneath your downspout.
! Modify your downspout
Cut your existing downspout using a saw so that the end can be placed over the top of your rain barrel.
Use a 3” vinyl downspout elbow to connect the two downspout pieces (or use a downspout adapter and
a piece of corrugated plastic pipe). Trim the end of the downspout if necessary.
STEP 1. Cut Holes in Barrel
! Cut lower drain hole
Measure about 1 inch above the bottom of the barrel where the barrel side begins to rise toward the
top. Using a ¾” bit (or hole saw), drill a hole through the barrel.
! Cut upper drain hole
Mark the upper drain hole according to where you want the overflow to be located in relationship to the
lower drain. Use a 1-5/8” hole saw to cut out the overflow hole.
! Cut top hole for atrium grate (filter)
Using the atrium grate as a template for size, mark a circle at the center of the top of the drum
(locating the rainwater inlet in the center of the barrel lets you pivot the barrel without moving the
downspout). Drill a ½” hole inside of the marked circle. Use a router, jigsaw or coping saw to cut until
the hole is large enough to accommodate the atrium grate, which filters out large debris. Don’t make
the hole too big – you want the flange of the atrium grate to fit securely on the top of the barrel without
falling in.
! Cut notch to hold hose
Using a ½” bit or hole saw, cut out a notch at the top of the barrel rim (aligned so that it is above the
lower drain hole). The notch should be large enough so that the end of the hose with the adapter will
firmly snap into place.
STEP 3. Assemble Parts
! Attach garden hose to lower drain hole
Screw in the ½” PVC male adapter to the lower drain hole. The hard PVC threads cut matching
grooves into the soft plastic of the barrel. Unscrew the ½” PVC male adapter from the hole. Wrap
threads tightly with teflon tape (optional). Coat the threads of the coupler with waterproof sealant
(optional). Screw the coated adapter back into the hole and let it sit and dry for 24 hours (optional).
Attach 5’ foot garden hose to the PVC male adapter. Attach the ¾” x ½” PVC male adapter to the other
end of the hose (this can be readily adapted to fit a standard garden hose).
! Attach drain hose to upper drain hole
Put the 1¼” male threaded coupling inside the barrel with the threads through the hole. From the
outside, screw the 1¼” female barbed fitting onto the threaded coupling. Use silicone on the threads
(optional). Attach 5’ section of drain hose to upper fitting.
! Place atrium grate and screen in top hole
Using PVC glue, secure a piece of fine mesh window screen inside or outside of the atrium grate to
filter out debris and control mosquitoes (optional). Place the atrium grate into the hole (basket down).
! Position the downspout
Position the end of your downspout so it drains onto the atrium grate on the rain barrel.
What Is a Rain Barrel?
A rain barrel collects and stores rainwater
from your rooftop to use later for things
like lawn and garden watering. Water collected
in a rain barrel would normally flow
through your downspout, onto a paved
surface, and eventually into a storm drain.
Why Use Rain Barrels?
!Rain barrels help lower water costs
(a rain barrel can save approximately
1,300 gallons of water during
peak summer months).
Instructions
Steps 1-3 below explain how to build and install your rain barrel. The supplies listed above can all be
found at most home improvement and hardware stores. The 55-gallon drums are available for $5 from
the Pepsi Bottling Company in Baltimore, or you can purchase a ready-to-install barrel from the South
River Federation. For more information contact the Rain Barrel Community Action Team at #410-
721-0661 or actionteams@southriverfederation.org.

Step 1: Size and Locate your Rain Garden
First, measure the footprint of your house and determine how much of your rooftop area drains to the
downspout you’re using for your garden (for gutters with a downspout at each end, assume that half
the water goes to each downspout). Be sure you measure the house footprint only; do not take the
roof slope into account. The surface area of your rain garden should be between 20% and 30% of the
roof area that will drain into the rain garden. Locate the garden at least 10 feet away from the house
(to prevent soggy basements), and maintain a minimum 1% slope from the lawn down to the rain
garden (you can also create a shallow ditch to ensure the water flows from roof to the garden, or use
a downspout extension to direct the flow into the garden). Lay out the boundary of the garden with a
rope.
Rain garden sizing example:
30’ x 30’ house area
1/4 of this area drains to one downspout
15’ x 15’ = 225 ft2
20% of 225ft2 = 45ft2
30% of 225ft2 = 67.5ft2
The rain garden area should be between 45 and 67.5 square feet,
depending on soil type (use 20% for sandier soils).
Step 2: Dig the Rain Garden
To enable the rain garden to hold several inches of water during a storm, you’ll have to dig a hole 3-
4 inches deep across the entire surface of the garden. If the soil lacks organic material, you can
improve it by digging the hole 5-6 inches deep, and adding 2-3 inches of humus or other organic
material. Make sure the bottom is level. Next, test how the garden will hold water during a storm by
letting water flow into the rain garden from a hose placed at the downspout. Based on this test,
make any necessary adjustments (e.g., create a berm on the lower side of the garden using the
diggings, or use a downspout extension or shallow ditch to direct the water into the garden).
Step 3: Add Plants to the Rain Garden
Choose drought-tolerant plants that won’t require much watering, but make sure they can withstand
wet soils for up to 24 hours. A list of native plants that meet these criteria is provided below. Also
take into account how much sun your garden receives. It’s often helpful to draw out a planting plan
before you start, and mark planting areas within the garden with string. After planting, weeding may
be required until the plants become more established. You may also need to periodically prune some
of the plants to let others grow. In the winter, leave dead or dormant plants standing and cut back in
the spring. Your garden may need a bit more maintenance than a lawn in the beginning, but in the
long run it will be easier to care for and provide many added benefits!
What Is a Rain Garden?
A rain garden uses native landscaping to soak up rain water from your downspout. The middle
part of the garden holds several inches of water, allowing it to slowly infiltrate into the ground
instead of being delivered to the stormdrain all at once.

Why Install a Rain Garden?
A rain garden allows 30% more water to infiltrate into the ground than a conventional lawn. This helps replenish the groundwater supply (important during
a drought!), and reduces the amount of pollution that reaches our streams through stormwater runoff. Since studies show that the first inch of rainfall is
responsible for the bulk of the pollutants in stormwater, a rain garden is designed to temporarily
hold water from a one-inch rainstorm, and slowly filter out many common pollutants like sediment,
oil, grease and nutrients. Rain gardens require less watering and fertilizer than conventional lawns,
and provide habitat for birds and butterflies.

FRSA/TRI Model Tile Guidelines – August 2005
PREFACE
In January, 1987, the Roof Tile Committee of the FRSA/NTRMA was commissioned to develop and write
consensus guidelines for the installation of concrete and clay roof tiles. Recently, the National Tile
Roofing Manufacturers Association (NTRMA) changed its name to Tile Roofing Institute. The consensus
document process included meetings over a period of eighteen (18) years, made up of roofing contractors,
manufacturers, suppliers, academia, roofing consultants, and engineers.
These guidelines were approved by a consensus vote of participating members. These guidelines are
updated or reaffirmed by the same process at intervals not exceeding three (3) years.
These guidelines were developed to summarize for the designer, applicator or developer good roofing
practice and industry guidelines for the installation of the mechanically-set and mortar/ adhesive-set tiles,
which have been developed over a period of time from actual trade practice and the requirements of various
building code agencies. These guidelines may not be applicable in all geographical areas. It is the
responsibility of those individuals who are referring to these guidelines to independently research and
determine which is best for their particular project. Accordingly, the Florida Roofing, Sheet Metal and Air
Conditioning Contractors Association and the Tile Roofing Institute and their members expressly disclaim
any express or implied warranties or any liability for any damages or loss that might be incurred as a result
of the use of these guidelines.

metal flashings with edge returns. Tiles are applied over the
underlayment with mechanical fasteners to the deck with or
without horizontal battens.
DISCLAIMER NOTICE (PLEASE READ CAREFULLY):
These mechanically fastened tile guidelines are a consensus document developed by a joint Task Force
of the Florida Roofing, Sheet Metal and Air Conditioning Contractors Association (FRSA) and the
Florida Chapter of the Tile Roofing Institute (TRI). It is important to recognize that these
recommendations are neither warranties, explicit or implicit, nor representative of the only method by
which a mechanically fastened tile system can be installed. Rather, they try to summarize for the
designer, applicator or developer good roofing practice and some of the industry standards for the
installation of the mechanically-set tiles which have been developed over a period of time from actual
trade practice and the requirements of various building code agencies. These guidelines may not be
applicable in all geographical areas. It is the responsibility of those individuals who are referring to
these guidelines to independently research and determine which is best for their particular project.

System Two
Mechanically Fastened Tile Guidelines
Sealed underlayment system using metal flashings without
edge returns. Tiles are applied with mechanical fasteners
direct to water-proofed deck.
DISCLAIMER NOTICE (PLEASE READ CAREFULLY):
These mechanically fastened tile guidelines are a consensus document developed by a joint Task
Force of the Florida Roofing, Sheet Metal and Air Conditioning Contractors Association (FRSA) and
the Florida Chapter of the Tile Roofing Institute (TRI). It is important to recognize that these
recommendations are neither warranties, explicit or implicit, nor representative of the only method by
which a mechanically fastened tile system can be installed. Rather, they try to summarize for the
designer, applicator or developer good roofing practice and some of the industry standards for the
installation of the mechanically-set tiles which have been developed over a period of time from actual
trade practice and the requirements of various building code agencies. These guidelines may not be
applicable in all geographical areas. It is the responsibility of those individuals who are referring
to these guidelines to independently research and determine which is best for their particular
project.

Anchor Sheet Fastening Table Instructions
The mean roof height limitations for attaching an anchor sheet to a wood surface substrate are based on many
variables. The nail spacing, type of nail, thickness of the sheathing, type of anchor sheet, and the pitch of the
roof are the variables we took into account to determine the mean roof height limitations in Tables 1.
Table 1
Table 1 is to be used when utilizing a two-ply, hot or cold process, underlayment system or for systems where a
cap sheet is bonded to an anchor sheet and applying roof tiles with an adhesive-set or mortar-set system. This
table indicates the fastening pattern for the field, the underlayment laps, any back nailing requirements of the
cap sheet for both smooth or deformed shank nails.
Tables 2A through 2D and 3A through 3D
Tables 2A through 2D are the required underlayment design pressures and required (conservative) hip and ridge
design pressures based on Exposure B. Tables 3A through 3D are the required underlayment design pressures
and required (conservative) hip and ridge design pressures based on Exposure C. (See the classification of
buildings and other structures for importance factors on page 104 and Exposure Categories on page 105.)
Instructions
Step 1) Determine the required underlayment design pressure from Tables 2A through 3D based on
the following parameters:
a) Classification of Buildings and Other Structures for Importance Factors: Determine from
the Classification of Buildings and Other Structures for Importance Factors and the
Exposure Categories listed on page 104 and 105.
b) Pitch of Roof: Acquire from job site.
c) Mean Roof Height: Acquire from job site.
d) Basic Wind Speed: Determine basic wind speed for your area from Basic Wind Speed
Map on page 106 and be sure to check with the local building code, especially for areas
where the boundary lines intersect a county.
Example
a) Exposure Category: B
b) Building Category: II
c) Importance Factor: 1.00
d) Type and Pitch of Roof: Gable – 5:12
e) Mean Roof Height: 20 feet
f) Basic Wind Speed: 140 mph
Based on the above mentioned parameters and Table 1, the required underlayment design pressure
for the example above = 77.7 psf
FRSA/TRI Model Tile Guidelines – August 2005
Anchor Sheet Table Instructions 102
Step 2) Determine the appropriate fastening pattern required to meet or exceed the underlayment
design pressures as determined in step 1 above. Refer to Table 1, the allowable uplift resistance
values are determined by the following parameters:
a) Determine the thickness of the sheathing (15/32” or 19/32”) from the job site.
b) Determine the type of nail to be used on the job site (smooth or ring shank).
c) Find the allowable uplift pressure from Table 1 that meets or exceeds the required design
pressure as determined from step 1 above. The anchor sheet must be attached to the
substrate according to the required fastening pattern determined above.
Example:
30 / 90 hot mop system
19/32” plywood (5/8”) – Use 19/32” columns
Ring Shank nails – use “Deformed” column under the 19/32” column
Using the example in step 1 above, use a fastening pattern that meets or exceeds 77.7 psf.
The minimum options are as follows:
1) Two rows 6” on center in the field 6” at the laps and back nail the cap sheet 12” on center. This
fastening pattern achieves 82.9 psf.
or,
2) Three rows 10” on center in the field 6” at the laps and back nail the cap sheet 12” on center.
This fastening pattern achieves 78.3 psf.
Either one of these fastening pattern options is an acceptable anchor sheet fastening pattern.

The above design pressures are conservative for any hip/ridge tile with an exposed area of 144 sq. inches
(1 sq. ft.) or less. Determine the actual square foot area of the tile being used using the following formula:
(A) ft2 = (W) (in inches) x (L) (in inches) / 144 (sq. in.)
(A) = Actual hip/ridge area (ft2)
(W) = The average exposed width of the hip/ridge tile (in inches).
(L) = The actual length of the hip/ridge tile (in inches) minus the head lap being used (typically 2”).
To determine the required hip/ridge design pressure for the tile being used, multiply (A) (sq. ft.) times the
appropriate design pressures listed in Tables 2A through 3D.

The above design pressures are conservative for any hip/ridge tile with an exposed area of 144 sq. inches
(1 sq. ft.) or less. Determine the actual square foot area of the tile being used using the following formula:
(A) ft2 = (W) (in inches) x (L) (in inches) / 144 (sq. in.)
(A) = Actual hip/ridge area (ft2)
(W) = The average exposed width of the hip/ridge tile (in inches).
(L) = The actual length of the hip/ridge tile (in inches) minus the head lap being used (typically 2”).
To determine the required hip/ridge design pressure for the tile being used, multiply (A) (sq. ft.) times the
appropriate design pressures listed in Tables 2A through 3D.

The above design pressures are conservative for any hip/ridge tile with an exposed area of 144 sq. inches
(1 sq. ft.) or less. Determine the actual square foot area of the tile being used using the following formula:
(A) ft2 = (W) (in inches) x (L) (in inches) / 144 (sq. in.)
(A) = Actual hip/ridge area (ft2)
(W) = The average exposed width of the hip/ridge tile (in inches).
(L) = The actual length of the hip/ridge tile (in inches) minus the head lap being used (typically 2”).
To determine the required hip/ridge design pressure for the tile being used, multiply (A) (sq. ft.) times the
appropriate design pressures listed in Tables 2A through 3D.
The required aerodynamic uplift moment values for determining the attachment of clay and concrete tiles are
based on many variables. The building category, importance factor, building exposure, basic wind speed, slope
of roof, and a generic tile dimension (tile factor) of 1.407 are the variables we took into account to determine
the required uplift moment in Tables 4A through 5D.
Tables 4A through 5D
Tables 4A through 4D are to be used for non-coastal construction.
Tables 5A and 5D are to be used for coastal construction.
1. Determine the building category and importance factor from page 104, and the exposure category from
page 105.
2. Determine the mean roof height and slope of the roof.
3. Select the appropriate table based on then information gathered from numbers 1 and 2 above.
4. Follow across the basic wind speed row to the appropriate basic wind speed for the project. Then follow
down the column to the appropriate mean roof height to determine the required aerodynamic uplift
moment.
Tables 6, through 10
1. Select Tables 6, 8 or 9 based on the thickness of the decking and if tiles will be attached directly to the
deck, or use Table 7 if the tiles will be attached to battens. Refer to Table 10 for Adhesive-set or Mortarset
systems.
2. Select an attachment method where the uplift capacity from Tables 6 through 9 is equal to or greater
than the appropriate aerodynamic values listed in Tables 4A through 5D. Refer to the adhesive, mortar
or roof tile manufacturer’s product approval or evaluation report for the resistance values for these
attachment systems.

Hip and ridge support member attachment recommendations.
For Hip and Ridge Attachment Requirements
FRSA/TRI Model Tile Guidelines – August 2005
Anchor Sheet Table Instructions 116
Required Aerodynamic Uplift Moment Tables Instructions
Note1: To determine the required design pressures for the hip/ridge tiles, use the appropriate table from
Tables 2A through 3D based on the job site parameters. The design pressures are conservative for any
hip/ridge tile with an exposed area of 144 sq. inches (1 sq. ft.) or less. Determine the actual square foot
area of the tile being used using the following formula:
(A) ft2 = (W) (in inches) x (L) (in inches) / 144 (sq. in.)
(A) = Actual hip/ridge area (ft2)
(W) = The average exposed width of the hip/ridge tile (in inches).
(L) = The actual length of the hip/ridge tile (in inches) minus the head lap being used (typically 2”).
Note2: Resistance values for the hip and ridge tile are proprietary, and are dependent on the system used
for attachment of the hip and ridge tile. Refer to Table 10 and the appropriate manufacturer’s product
approval or evaluation report to determine the proper attachment method to meet or exceed the
hip/ridge design pressures.

Foreword
These recommendations were developed after surveying the recent hurricanes and with input from the
code, roofing and tile manufacturing community. They are designed to further clarify the current
installation procedures as they pertain to the specific roof tile systems (Mechanically fastened, Adhesiveset
or Mortar-set).
The following recommendations provide for only products approved by the FBC (Florida Building Code),
tested according to SSTD-11 and verified by third party independent FBC approved laboratories, to
determine the wind uplift limitations of the various hip and ridge attachment methods or by installation
methods currently recognized in the HVHZ (High Velocity Hurricane Zone) section of the FBC.
A joint sub-committee consisting of members from the FRSA (Florida Roofing, Sheet Metal and Air
Conditioning Contractors Association, Inc) and the TRI (Tile Roofing Institute) drafted these
recommendations and they were approved by consensus by the FRSA Roof Tile Committee.

1. Introduction
1.1. Purpose
1.1.1. This document is to be used as a supplement to the FRSA/TRI “Concrete and Clay Roof
Tile Installation Manual” – Fourth Edition, specifically the sections of Systems 1, 2, 3 and
4, pertaining to hip and ridge attachment. Recent wind events have established the need to
provide greater attention to hip and ridge attachment systems. In order to prevent similar
occurrences, all hip and ridge attachment systems must be tested to show compliance to the
wind loads set forth by the FBC. The test results will establish the mean roof height
limitations for each of the hip and ridge attachment systems. The prescriptive method of
hip and ridge applications will no longer be accepted.
1.2 Scope
1.2.1 These recommendations set the requirements for the hip and ridge attachment for Systems
1, 2, 3 and 4 of the FRSA/TRI “Concrete and Clay Roof Tile Installation Manual” -
Fourth Edition.
1.2.2 These recommendations and any other newly developed recommendation shall be tested
under laboratory conditions according to SSTD-11 to determine the wind uplift resistance
of the specific hip and ridge attachment system. An additional tile factor of 2-to-1 above
that specified in SSTD-11 or TAS 101 shall be applied in determining the ‘allowable
overturning moment’ or ‘attachment resistance expressed as a moment (Mf)’ to account
for any interdependence hip and ridge attachment methods used.
1.2.3 The wind resistance performance of the hip and ridge system depends in part on its ability
to resist the uplift forces at the perimeter edge and the attachment of the adjoining field
tile.
1.2.4 These recommendations are not intended to determine which hip and ridge system is more
or less suitable for the user of the product. Conditions, under which the hip and ridge
attachment system is used, vary widely. It is the ability of the manufacturer and the user to
determine the suitability of the hip and ridge system for the intended job location.
1.2.5 These recommendations are not intended to determine which hip and ridge system is more
or less suitable as a weather blocking system or the system’s ability to restrict or prevent
the infiltration of air or water into the tile system. It is the responsibility of the user to
determine the most effective weather blocking system for the intended job location.
1.3 Basis for Requirements
1.3.1 These recommendations are based on experience, research and testing and/or the
standards of other organizations. The advice of manufacturers, users, and trade
associations was also considered.
FRSA/TRI Model Tile Guidelines – August 2005
Hip and Ridge Installation Instructions Page 5 of 30
1.3.2 These recommendations prohibit component substitution without proper laboratory testing
and a FBC Product Approval.
1.3.3 The recommendations reflect tests and practices used to examine characteristics of hip and
ridge attachment. These recommendations are intended as guides and strict conformity is
not always mandatory. Hip and ridge attachment systems having characteristics not
anticipated by these recommendations may be satisfactory if performance equal or
superior to that required by these recommendations is demonstrated.

2. General Information
2.1. Hip and Ridge Attachment System Information
2.1.1. Hip and ridge attachment systems are used for weather blocking at the terminations of two
adjoining roof planes. Experience has shown that adequate attachment of the hip and ridge
tile systems is extremely important to maintaining weather blocking and to minimize
ancillary missiles from being created which may occur when hip and ridge tiles impact the
field roof tile. Adequately secured field tiles may be vulnerable to wind damage if the hip
and ridge tile system is improperly installed. To achieve the specified wind uplift results,
follow the hip and ridge application procedures, which shall be representative of the tested
assembly.
2.1.2. Hip and ridge attachment system failures occur when wind uplift or pressure exerts forces
beyond the resistance strength of the hip and ridge attachment and/or of the structural
support to the substrate. When the hip and ridge tile and/or the adjoining field tile are not
properly secured, the resulting prying action and uplift forces may cause the hip and ridge
attachment to fail. When this occurs the roof tile system becomes vulnerable and may
cause ancillary damage and may subject the building to additional rain and/or additional
roof tile securement damage.
2.1.3. Hip and ridge tile systems must adequately terminate the adjoining planes. There are three
basic types of weather blocking methods used in Florida, foil-faced self-adhered
membrane, adhesive and mortar:
Foil-faced self-adhered Membrane System is typically used when a wood hip and ridge
frame has been secured to the substrate, the foiled backed membrane is applied in a step
fashion sealing to both sides of the adjoining field tile planes prior to the mechanically
attachment to the wood frame. It can also be used on a metal hip and ridge frame where
mechanical attachment of the hip and ridge tile is an acceptable attachment method. Can
be used with all roof tile systems.
Adhesive is used to weather block the entire cavity of the adjoining planes of field tile to
the sides of the structural support. Can be used with all roof tile systems.
Mortar (pre-bagged or job-site mix) is used to weather block the longitudinal edges of
the hip and ridge tiles to the adjoining field tile roof planes. Can be used with all tile
systems.
FRSA/TRI Model Tile Guidelines – August 2005
Hip and Ridge Installation Instructions Page 7 of 30
2.1.4 Hip and Ridge tiles must be adequately attached to transfer the loads to the substrate.
There are three basic attachment methods of the hip and ridge tiles used in Florida,
mechanical attachment, adhesive-set and mortar- set attachment systems:
Mechanical Attachment is the securement of the hip/ridge tiles with nails or screws at the
head of the tile in addition to a FBC approved adhesive at the hip/ridge tile overlaps.
Adhesive-set is the securement of the hip/ridge tiles to a structural support with a full bed
of adhesive or other FBC approved paddy method.
Mortar-set is the securement of the hip/ridge tiles along both longitudinal edges of the
adjoining planes of field tile embedded in a full bed of pre-bagged FBC approved
mortar only.
2.1.5 Hip and Ridge tile attachment methods are also categorized by whether or not the
attachment system is an independent attachment system or an interdependent attachment
system. An example of an independent attachment is when the hip/ridge tile is attached in
a full bed of adhesive or mortar. An interdependent attachment system is when the load is
being applied to more than one tile. An example is a mechanical fastener used at the head
of the hip/ridge tile and adhesive used at the overlap joining both tiles together. When the
load is being applied to the hip/ridge tile, the resistance is shared with the nail installed at
the head of the tile and the adhesive at the hip/ridge tile overlap, which is transferring the
load to the nail of the previously installed hip tile.
2.2. Approval Ratings and Limitations
2.2.1. The uplift resistance values achieved from the laboratory testing shall determine the mean
roof height limitation of the hip and ridge attachment system.
2.2.2. The resistance values for mechanical fasteners shall be posted in the roof tile
manufacturers FBC Product Approval.
2.2.3. The resistance values for adhesive-set system shall be posted in the roof tile adhesive
manufacturers FBC Product Approval.
2.2.4. The resistance values for mortar-set system shall be posted in the roof tile mortar
manufacturers FBC Product Approval.

3.4.1 The adhesive-set and mortar-set manufacturers shall provide a joint qualified applicator
program.
4. Hip and Ridge Tile Attachment Systems
NOTE: This document was written for projects utilizing hip and ridge tile. For mitered hip and
ridge applications refer to the tile manufacturers recommendations.
4.1 Hip and Ridge Tile Attachment Descriptions
4.1.1 There are four roof tile installation systems currently listed in FRSA/TRI ‘Concrete and
Clay Roof Tile Installation Manual, System One, System Two, System Three and System
Four ‘A’ & ‘B’. Only System Three and System Four ‘B’ allows for the use of a FBC
approved pre-bagged mortar to attach hip and ridge tiles without the use of a wood,
metal or other structural support.
The three (3) most common methods for installing hip and ridge tile are mechanically
fastened, Adhesive-set and mortar-set attachment systems:
1) Mechanically Fastened Hip and Ridge Attachment System – This attachment
system consists of installing typically a wood hip and ridge frame (or other
structural support equal to or superior to resist the pullout of mechanical fastener)
secured to the substrate according to the FRSA/TRI Concrete and Clay Roof Tile
Installation Manual or the requirements of the HVHZ requirements of the (FBC)
Florida Building Code, or having a FBC product approval meeting the
requirements of the FBC, specifically rule 9B-72. The weather blocking
mechanism is either accomplished with adhesive tested for a weather block, prebagged
or job site mix mortar or with a step flashing using a foil-faced self-adhered
membrane. The hip/ridge tiles are mechanically attached to the structural support
with mechanical fasteners and a FBC code-approved roof tile adhesive at the
hip/ridge tile overlaps.
FRSA/TRI Model Tile Guidelines – August 2005
Hip and Ridge Installation Instructions Page 9 of 30
2) Adhesive-set Hip and Ridge Attachment System – This attachment system
consists of installing a wood or metal hip and ridge frame (or other structural
support) secured to the substrate according to the FRSA/TRI Concrete and Clay
Roof Tile Installation Manual or to the requirements of the HVHZ requirements of
the (FBC) Florida Building Code, or having a FBC product approval meeting the
requirements of the FBC, specifically rule 9B-72. The weather blocking
mechanism is either accomplished with mortar or with a FBC code-approved roof
tile adhesive or other FBC code-approved weather blocking material, designed and
tested specifically for roof tile weather blocking applications. The hip/ridge tiles are
attached to the structural support with a FBC approved adhesive according to the
adhesive manufacturers recommendations based on the FBC approved independent
laboratory testing or according to the requirements of the HVHZ requirements of
the FBC. For slopes over 7:12, additional securement at the hip may be necessary
to prevent tile movement until adhesive is cured.
3) Mortar-set Hip and Ridge Attachment System – This attachment system consists
of installing hip and ridge tiles into a bed of FBC approved mortar tested
specifically for hip and ridge tile applications and meet the requirements of the
(FBC) Florida Building Code, specifically rule 9B-72. The mortar is used as the
attachment and waterproofing mechanism. For slopes over 7:12, additional
securement at the hip may be necessary to prevent tile movement until mortar is
cured.
4.2 Field Cut Roof Tile Requirements
4.2.1 All field cut tiles (two tiles on each side of hip) and the top course of ridge must be
attached to the substrate with code-approved adhesive, code-approved mortar or
mechanical fasteners and adhesive. (See Drawings 1 and 2). In situations where the ridge
course of tile has been cut, the field cut tile and the full tile course below the cut tile must
be attached to the substrate as well. This requirement is designed to minimize any dynamic
movement of the field cut tiles, at the most stringent zones of the roof, which may occur
during a high wind event such as hurricanes. (See Drawings 3).
4.2.2 The minimum head lap when installing the hip and ridge tiles is 2”, as stated in the
FRSA/TRI manual. It may be necessary to increase the head lap to cover exposed hip/ridge
tile fastening holes or adhesive. Cover exposed fasteners with a UV resistant sealant.
4.3 Hip and Ridge/Field Tile System Limitations
4.3.1 There are three attachment methods for securing hip and ridge tile, mechanically attached,
adhesive attached, and Mortar attached. These methods can only be used on field tile
attachment systems as follows:
Mechanically Attached Hip and Ridge Tiles – Can be used on field tile attachment
Systems One, Two, Three and Four, as listed in the FRSA/TRI Manual.
Adhesive-set Hip and Ridge Tiles – Can be used on field tile attachment Systems One,
Two, Three and Four, as listed in the FRSA/TRI Manual.
Mortar-set Hip and Ridge Tiles – Can be used on field tile attachment Systems Three and
Four ‘B’ only, as listed in the FRSA/TRI Manual.
FRSA/TRI Model Tile Guidelines – August 2005

5.2 Weather Blocking Options
5.2.1. After completion of the structural support attachment choose the desired weather
blocking method for the specific attachment system. The three most common
weather blocking methods are:
1) Foil-faced Self-adhered Membrane Weather Blocking System
2) FBC Approved Adhesive Tested as a Weather Blocking System
3) (Pre-bagged or Jobsite Mix) Mortar Hip/Ridge Weather Blocking System
5.2.2. Foil-faced Self-adhered Membrane as a Weather Block.
5.2.2.1. This system uses self-adhered membrane as weather block. No mortar is used
along the longitudinal edges of the tile. Mortar can be used at the hip/ridge,
hip/valley, ridge/valley, and ridge/gable (etc) junctions as a weather block.
5.2.2.2. Install foil-faced self-adhered membrane over hip/ridge frame (foil side up) in
a step flashing method per membrane manufacturer’s recommendations and
seal to field tile. (See Drawings 7 &
5.2.2.3. Care should be taken to ensure the self-adhered membrane is sealed to the tile
surface. Ensure hip/ridge, ridge/gable, ridge/valley and hip/eave junctions are
sealed to prevent water entry of those areas.

5.2.3 Adhesive Used as a Weather Block
5.2.3.1 This system uses adhesive as weather blocking system. There is no mortar
placed along the longitudinal edges of the hip and ridge tile. Adhesive is
placed where the field tile abuts to the structural support. A bead of adhesive
is placed parallel to the hip and/or ridge board tile junction to act as a weather
block and is applied prior to the attachment of the hip and ridge tile.
5.2.3.2 Install adhesive to seal all voids between the tile and the structural support
according to the adhesive manufacturers recommendations. Care should be
taken to ensure all areas are sealed with adhesive to prevent water entry.

5.3. Hip and/or Ridge Starter Tile Attachment
5.3.1 Starting at the eave, place hip starter tile over wood hip frame, positioning in the center of
the structural support. Secure the head of the starter tile to the structural support with a
mechanical fastener conforming to the FRSA/TRI Concrete and Clay Roof Tile Installation
Manual.
5.3.2 Care must be taken to properly secure the first (starting) hip and ridge tile of the hip/ridge
attachment system. Additional securement at the hip starter tile installed at the eave and at
the starting ridge tile installed at either the ridge/hip or ridge/gable junctions are necessary
to prevent the tile from overturning during a high wind event.
5.3.3 Typically the structural support is kept 6” to 12” back from the eave to allow for the
aesthetic placement of mortar used as a weather block and closing off the hip end at the
eave. It may be necessary to extend or cantilever the structural support toward the eave to
ensure adequate support for the hip tile attachment. (See Drawing 25) All hip or ridge
starter tile must be secured at the both ends of the tile either with mechanical fasteners or
adhesive. Although this section mentions hip starter tiles, the same is true for the starting
ridge tile. Some options are listed below:
1) Drill a 3/16”hole within lower one-third of the tile length, from the eave end of
the hip starter tile. Secure the eave end of the starter tile with a mechanical
fastener embedding into the structural support, a minimum of ”. Seal the head
of the fastener with a UV resistant sealant. Adhesive may also be used in lieu of
a fastener at the starting end of the tile as long as the structural member has
been cantilevered to provide a base for adhesive attachment.
2) Prior to installing the hip starter tile, apply a code-approved roof tile adhesive
along the entire length of the hip starter tile according to the adhesive
manufacturers installation instructions. Secure the head of the tile with
mechanical fastener embedding into structural support, a minimum of ”.
3) Prior to installing the hip starter tile, place a full bed of only FBC codeapproved
pre-bagged mortar according to the mortar manufacturers
installations instructions under the entire hip starter tile. Within 2 minutes of
placing the bed of mortar, embed the entire hip starter into the solid bed of
mortar. Secure the head of the tile with mechanical fastener embedding into
structural support, a minimum of ” . Point mortar to desired finish. When
using this mortar method for securing the starter hip tile, ensure
underlayment is approved for use with mortar-set applications.
FRSA/TRI Model Tile Guidelines – August 2005
Hip and Ridge Installation Instructions Page 19 of 30
5.4 Hip and Ridge Tiles Mechanically Attached to Structural Support
5.4.1 Prior to installing subsequent hip/ridge tiles place a minimum 4” to 5” bead of FBC
approved roof tile adhesive along the head of the hip starter tile. Install the next hip
tile, centering over the wood frame and lapping the starter tile a minimum of 2”.
(See Drawing 8). If the overlap is restricted by product design, refer to the tile
manufacturers installation instructions. Continue in same manner working from the
lowest point toward the highest point of the roof. At intersecting junctions (i.e.
hip/ridge, ridge/gable, ridge/valley) cut tile to form a solid fit and ensure the first
and the last hip/ridge tile is securely fastened. Any exposed fasteners must be
sealed with a UV resistant sealant.
5.4.2 Optional: Prior to installing the tiles at these adjoining junctions, place a full bed
(filling entire cavity) of FBC approved pre-bagged mortar under the entire
adjoining hip/ridge tile. Embed the entire hip/ridge tile into the solid bed of mortar.
Point mortar to desired finish. Fasten as mentioned above. Use the three methods
under Note 5 above as guidelines and/or options at these junctions.
6.0 Adhesive-set Hip and Ridge Attachment System
6.1. Adhesive-set Hip and Ridge Attachment System – Structural Support Options
6.1.1 Adhesive-set hip and ridge tiles can be installed directly to a structural support. The
most common structural supports are:
1) Wood Hip and Ridge Frame (See Drawings 4, 5, & 6)
2) Metal Hip and Ridge Frame (Metal Channel) (See Drawing 14)
6.1.2. Determine how you want to attach the wood hip and ridge frame to the substrate. The three
most common methods to attach the wood hip and ridge frame to the substrate are:
1) Metal Brackets – (See Drawing 4)
2) Metal Straps – (See Drawing 5)
3) FBC approved Adhesive – (See Drawings 15 & 17)
6.1.3. Attachment of the wood or metal hip and ridge frame to the substrate must be according to
Table 11 of the FRSA/TRI Concrete and Clay Roof Tile Installation Manual or according
to the HVHZ requirements of the FBC. (See Appendix A for a copy of the FRSA/TRI
Table 11).

6.2 Adhesive Weather Blocking System Options
6.2.1 Once the attachment method has been completed a choice has to be made on the
weather blocking method. The two most common methods are:
1) FBC Approved Adhesive Tested as a Weather Blocking System –
(See Drawings 15 and 17)
2) (Pre-bagged or Jobsite Mix) Mortar Weather Blocking System –
(See Drawings 11,12 and 13)
6.2.2. Adhesive Used as a Weather Block
6.2.2.1.This system uses adhesive as weather blocking system. There is no mortar
placed along the longitudinal edges of the hip and ridge tile. Adhesive is placed
where the field tile abuts to the structural support. A bead of adhesive is placed
parallel to the hip and/or ridge board tile junction to act as a weather block and
is applied prior to the attachment of the hip and ridge tile.
6.2.2.2.Install adhesive to seal all voids between the field tile and the structural support
according to the adhesive manufacturers recommendations. Care should be
taken to ensure all areas are sealed with adhesive to prevent water entry.

6.2.3 Mortar Used as a Weather Block
6.2.3.1 This system uses mortar as weather blocking system and for aesthetics. A full
bed of mortar is placed along the longitudinal edges of the hip and ridge tile
either during the application of the hip and ridge tiles or may be packed in
after the hip and ridge tiles are installed and the adhesive has cured. The hip
and ridge tiles are adhesive-set to the structural support in addition to the
mortar.
6.2.3.2 Install mortar to seal all voids between the field tile and the hip/ridge tile
according to the mortar manufacturers recommendations. Care should be taken
to ensure enough mortar is used, to create a wedge, to eliminate the potential
of the mortar from dislodging from the hip/ridge and field tile junction. Ensure
areas are sealed to prevent water entry. After mortar is packed into place point
mortar to desired finish. (See Drawings 11, 12 & 13)

6.3. Adhesive-set Hip and Ridge Starter Tile Attachment
6.3.1 Starting at the eave, and prior to installing the hip starter, place a bead or paddy of FBC
approved roof tile adhesive parallel to and on top of the wood or metal frame according to
the adhesive manufacturer’s instructions. An alternate method is to place the adhesive in
the center of the underside of the hip/ridge tile, turn hip/ridge tile over and carefully place
and center the tile over the structural support. The method of the paddy placement
location must be representative of how the adhesive manufacturer tested the hip and ridge
attachment method.
6.3.2 At the eave, place first hip (starter) tile over the metal or wood hip frame, positioning the
tile in the center of the frame. Install the hip starter tile over the adhesive paddy or bead.
Fasten hip tiles when the roof slope is greater than 7:12. The fasteners hold the tiles in
place until the adhesive can cure.
6.3.3 Optional: Prior to installing subsequent hip tiles, Place a minimum 4” bead of codeapproved
roof tile adhesive along the head of the hip starter tile.
6.4 Adhesive-set Hip and Ridge Tile Attachment
6.4.1 Install the next hip tile, centering over the frame and lapping the starter tile a minimum of
2”. (See Drawings 16, 17 & 18). If the overlap is restricted by product design, refer to the
tile manufacturers installation instructions. Continue in same manner working from the
lowest point toward the highest point of the roof. At intersecting junctions (i.e. hip/ridge,
ridge/gable, ridge/valley) cut tile to form a solid fit and ensure the first and the last
hip/ridge tile is securely fastened. Any exposed fasteners must be sealed with a UV
resistant sealant.
6.4.2 Optional: Prior to installing the tiles at these adjoining junctions, place a full bed (filling
entire cavity) of FBC approved pre-bagged mortar under the entire adjoining hip/ridge
tile. Embed the entire hip/ridge tile into the solid bed of mortar. Point mortar to desired

7.1. Mortar-set Hip and Ridge Tile Attachment limitations
7.1.1 Mortar-set Hip and Ridge Tile Attachment System can only be used with field tile
attachment Systems Three and Four ‘B’ and can only be installed with pre-bagged
FBC approved (specifically according to Rule 9B-72) mortar tested to determine
the limitations of the product application.
7.2. Mortar-set Hip and Ridge Starter Tile Attachment
7.2.1 Prior to installing any hip/ridge tile, a full solid bed of mortar is placed at the eave
end of the hip or ridge starter tile and parallel to the hip and/or ridge structural
support under where the longitudinal edge of the hip/ridge tile is to be placed. (See
Drawings 19, 20, 21, 22, 23 & 24) For Medium, High or Two-piece Barrel
profiled tiles, it will be necessary to stack 10” trowel full of mortar on top of each
other in the pan portions of the tile, to get the proper height of the mortar to
properly embed the hip/ridge tile 1 ” into the mortar bed. (See Drawing 22)
Pre-bagged or job site mixed

excess mortar and point to desired finish.
7.2.4. Care must be taken to embed the tile into the mortar a minimum of 1 ”. (Do not
just fill the voids of the tile edges with mortar). The packing of mortar into the
cavities between the hip/ridge tiles and the field tile are not allow for the structural
attachment of the hip and ridge tiles. The tile must be embedded into the mortar.

7.3 Mortar-set Hip and Ridge Tile Attachment
7.3.1 Position and install the next hip tile, centering over the hip junction and lapping the
starter tile a minimum of 2”. Embed the tile into the mortar bed a minimum of 1
”. (See Drawing 22). If the overlap is restricted by product design, refer to the
tile manufacturers installation instructions. Continue in same manner working from
the lowest point toward the highest point of the roof. At intersecting junctions (i.e.
hip/ridge, ridge/gable, ridge/valley) cut tile to form a solid fit and ensure the first
and the last hip/ridge tile is securely fastened. Any exposed fasteners must be
sealed with a UV resistant sealant.
7.3.2 At all junctions (i.e. hip/ridge, ridge/gable, ridge/valley etc.) fill all voids with
mortar. Prior to installing the junction tiles a bed of mortar must be placed to
minimize any cracking of the mortar. These cut or mitered tile must be embedded
into the mortar. Point mortar to desired finish.
7.3.3 Optional: The entire cavity of the hip and ridge tile may be filled a bed of mortar
in lieu of longitudinal beads placed parallel to the hip and ridge junction.
(See Drawing 20)
Use only FBC approved mortar that has
been tested according to ICC – SSTD-11
and has data substantiating compliance.

CREOSOTE AND SOOT – Formation and need for removal
When wood is burned slowly it produces tar and other organic vapours,
which combine with expelled moisture to form creosote. The creosote
vapours condense in the relatively cool chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on the flue lining. When
ignited this creosote makes an extremely hot fire.
COAL
Some coals contain large quantities of Sulphur (up to 7%). When coal is
burned, Sulphur and coal ash are deposited in the chimney flue. This
deposit combines with moisture to form a highly corrosive acid (Sulphuric
Acid).
In order to protect your chimney, we recommend that you:
1. Burn only low Sulphur coals (less than 1% Sulphur).
2. Have your chimney cleaned within 48 hours of shutting down your
stove at the end of the heating season. Be certain that all the soot is
removed.
WOOD AND COAL STOVES
If you are planning to install a wood stove, we recommend that you:
1. Choose a stove that has a label of a recognized Testing Laboratory
(such as WH, ULC, ULC, CSA). The EPA approved, low emissions
stoves are highly recommended.
2. Connect only one solid fuel burning appliance to a chimney. Do not
connect an oil or gas burning appliance to a chimney venting a solid
fuel burning appliance.
3. Never over fire your stove. If any part of the stove or stove pipe is
glowing red, then you are over firing. Immediately close the stove’s
damper until the system cools. The high temperatures caused by over
firing can permanently damage the stove and stove pipe and may overheat
nearby combustible walls and furniture.
4. Install the stove and stove pipe as described in the Installation
Instructions accompanying the stove. BE CERTAIN TO MAINTAIN
THE REQUIRED CLEARANCES TO COMBUSTIBLE
CONSTRUCTION.
5. Keep your flue gases between 300°F and 500°F. This will maximize
efficiency while minimizing condensation and creosote formation.
6. Do not burn sea driftwood. Salt is highly corrosive to all types of
stainless steel. Do not burn treated lumber.

RETROFIT APPLICATION
1. Mark the ceiling location for your skylight. Try to install between the
rafters to minimize your work (reference section 3). Before cutting, carefuly
check for electrical wiring above the ceiling. A carefully cut inspection hole
should be used. Cut and remove ceiling and insulation.
2. Make a 3/8’ or 1/2” thick plywood backer board to fit on top of the
rafters under the roof sheet metal. This backer board is used to give the
skylight mounting screws an attachment under the thin sheet metal
roof. The hole in the backer board is the same size as the skylight
roof opening. The backerboard outside dimensions are the same or
larger than the overall dimensions of the skylight. flanges.

3. Locate the roof openings directly above the hole in the ceiling (use a
square). Draw lines perpendicular with the room ceiling up to the
underside of the roof. Use a sharp object like an awl or ice pick to
push four dents or holes in the roof. This defines the corners of the
skylight opening on to the roof. Use 2 x 4’s or 2 x 2’s to frame the
tunnel up to the roof. Make sure all ceiling and tunnel paneling
edges are supported.
4. On top of the roof, locate the awl or icepick dents and mark the
dotted cut lines.
The cut lines on many roofs can be deeply scribed with a utility
knife and peeled open like a rooftop tin can. If the roof metal is too thick
to peel, use tin snips. Fold the one inch wide edges over flat on top of the
roof and nail onto the backer board and rafter.

5. ALL CAULKING IS TO BE APPLIED TO SKYLIGHT BEFORE MOUNTING. Do not remove protective plastic
cover from the glaze until the skylight is completely installed. Center the skylight above roofing (holding the
skylight away from the roof surface). When you are satisfied with the location, rest the skylight on the roof. Be
sure bottom pane is resting on the roof around the entire perimeter. Install the fasteners, first from the center
of each side and work to each corner. Tighten the fasteners only to the point when you can visually see
uniform compresssion of the caulk. Do not over-tighten fasteners, as it will distort the material making sealing
more difficult. Apply additional caulk to cover screws and to fill any voids around the perimeter, smooth excess
by hand. Finish interior tunnel and then remove the protective plastic from the interior glaze WARNING:
BOTTOM PANE MUST BE SUPPORTED!
SUGGESTED INTERIOR FINISH
Clean plastic with soap and water
ONLY.
6. Insulate tunnel with fiber glass batts stapled or taped in
place. Cut tunnel wall panels from matching ceiling or paneling
and nail in place
