IMPORTANT: PLEASE READ AND
UNDERSTAND THESE RULES TO
FOLLOW FOR SAFETY.
1. Before starting your fireplace installation,
read these installation instructions carefully to
be sure you understand them completely and in
entirety. Failure to follow them could cause a
fireplace malfunction resulting in serious injury
and/or property damage.
2. Always check your local building codes. The
installation must comply with all local, regional,
state and national codes and regulations.
3. These fireplaces must be installed with
Security Chimneys FTF10 (10" inside diameter) Chimney System only. These systems
are intended for use in any application where
a traditional masonry type fireplace would
apply. The chimney system must always vent
to the outside of the building.
4. To ensure a safe fireplace system and to
prevent the build-up of soot and creosote,
inspect and clean the fireplace and chimney
prior to use and periodically during the heating
season.
5. Use solid fuel only. DO NOT use artificial
wax based logs, chemical chimney cleaners or
flame colorants in your fireplace.
6. DO NOT use charcoal or coal under any
circumstances.
7. NEVER use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen up” a fire in this
fireplace. Keep any flammable liquids at safe
distance from the fireplace.
8. NEVER leave children unattended when
there is a fire burning in the fireplace.
9. Always keep flue damper open when heat is
present in the fireplace.
10. Before servicing, allow the fireplace to
cool. Always shut off any electricity or gas to
the fireplace while working on it. This will
prevent any possible electrical shock or burns.
11. This fireplace is not intended to heat an
entire home or be used as a primary heat
source. It is designed to ensure homeowner
comfort by providing supplemental heat to the
room.
12. Always ensure that an adequate supply of
replacement combustion air from the outside
of the house is accessible to the fire to support
normal combustion. Fireplaces consume large
volumes of air during the normal combustion
process. In the event the home is tightly sealed
with modern energy efficient features, the optional combustion air kit may not provide all the
air required to support combustion.
The manufacturer is not responsible for any
smoking or related problems that may result
from the lack of adequate combustion air. It is
the responsibility of the builder/contractor to
ensure that adequate combustion air has been
provided for the fireplace.
13. DO NOT use a fireplace insert or any other
products not specified herein by the manufacturer for use with this fireplace. All gas log sets
must be operated with the damper clamped
open, including unlisted “vent free” log sets.
Listed “vent-free” log sets may be operated
with the damper closed.
14. "Smoke free” operation is not warranteed
nor are we responsible for inadequate system
draft caused by mechanical systems, general
construction conditions, inadequate chimney
heights, adverse wind conditions and/or unusual environmental factors or conditions beyond our control.
15. Never, under any circumstances, install a
fireplace, chimney component or any accessories, that has visible or suspected physical
damage as a result of handling or transportation. These items should be inspected by your
distributor or qualified factory representative
to ensure safe condition. When in doubt, consult your distributor.
16. For additional safety considerations and
complete operating instructions, refer to the
Care and Operation Manual provided with the
fireplace.

PRECAUTIONS
Note: These fireplace systems are not difficult
to install. However, in the interest of safety, it is
recommended that the installer be a qualified or
certified “tradesman” familiar with commonly
accepted fireplace installation and safety techniques as well as prevailing local codes.
The most important areas of concern dealing
with the installation of factory-built fireplaces
are clearances to combustible materials, proper
assembly of component parts, height of the
chimney system, the proper use of accessories supplied by the manufacturer and the
techniques employed in using finishing materials applied to the wall surrounding the fireplace, hearth extensions and wall shields. Each
of these topics will be covered in thorough
detail throughout this manual. Please give
each your special attention as you progress
with your installation.
INTRODUCTION
General Information
These fireplaces are conventional radiant heat
fireplaces with standard bar grates, optional
outside combustion air kits and optional decorative glass doors.
Note: Illustrations shown reflect “typical”
installations with nominal dimensions and
are for design and framing reference only.
Actual installations may vary due to individual design preferences. However, always
maintain minimum clearances to combustible materials and do not violate any specific
installation requirements.
These fireplaces have been tested and listed by
Warnock Hersey (Report No. J20017261-231)
to U.L. standard 127. These units are intended
for installation in residential homes and other
buildings of conventional construction including commercial, not in mobile homes.
CLEARANCES AND HEIGHT
REQUIREMENTS
The fireplace may be placed on or near normal
construction materials*. The combustion air
kit, firestop spacer and roof flashing (not chase
flashings) may be placed directly on or against
normal construction materials.* The chimney
and fireplace outer wrapper require a minimum
2" air space to combustibles. A combustible
mantle may be installed 12" above the opening
of the fireplace as per NFPA 211, Section 7-
2.3.3.
The minimum installed height of the completed
fireplace system is 15' 0". The maximum height
is 60' 0".
The fireplace and chimney system must be
enclosed when installed in or passing through
a living area where combustibles or people may
come in contact with it. This is important to
prevent possible personal injury or fire hazard.

Note: Local codes may not require firestopping
at the ceiling levels for outside chase installations. However, it is recommended for safety
and the reduction of heat loss.
Chimney Height
The total height of your completed fireplace
system from the surface the fireplace rests on
to the chimney top must not exceed 60' and
must also meet minimum height requirements.
Refer to the minimum system height chart.

Chase Enclosure
A chase is a vertical box-like structure constructed to surround the fireplace and chimney.
Refer to
Figure 2
for a typical chase configuration. As with all chimney installations, avoid
overhead obstructions such as trees, power
lines, etc. A chase should be constructed and
insulated just like any outside wall. In a cold
climate, we recommend the base of the chase
should also be insulated between the solid
continuous floor beneath the fireplace and the
chase bottom. Chase insulation in a cold climate installation is not required for safety.
ASSEMBLY OUTLINE
Before You Start
Check your inventory list to be sure you have all
the necessary parts supplied in good usable
condition. Check also for any concealed damage.
Check the operation of the damper. The damper
is controlled through the use of a control lever
located within the firebox opening at the top
center just behind the firebox lintel (
The control lever snaps into place at the extreme range of motion, up and back in the
closed position. When pulled forward and
down, the damper is open.

room from under the fireplace.
The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.
Usually, no special floor support is needed for
the fireplace, however, to be certain:
INSTALLING THE FIREPLACE
Step 1. Slide the fireplace into prepared fram-
ing or position fireplace in its final position and
frame later.
The fireplace may not be recessed into a combustible floor. Maintain the floor to hearth
clearance established by the fireplace lower
front face.
Figure 5
DO NOT permanently place furniture or other
items such as decorative pillows within 60" of
the fireplace front face.
ASSEMBLY STEPS
Note: The following steps represent the normal
sequence of installation. Each installation is
unique, however, and might require a different
sequence.
1. Position firebox prior to framing or into
prepared framing.
2. Install the chimney system.
3. Install optional outside combustion air kit.
4. Plumb gas line if a decorative gas appliance
will be used. (Gas connections should only be
performed by an experienced, licensed/certified tradesman.)
5. Complete the installation, finish wall material, surround and hearth extension to your
individual taste.
6. Assemble and attach optional glass door
assembly.
Study the three dimensional illustration (
ure 1
) to get a general idea of each element of
Fig-
your fireplace system.
PRE-INSTALLATION NOTES
The fireplace may be installed directly on a
combustible floor or raised on a platform of an
appropriate height. Do not place fireplace on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, plywood, particle board or other hard surfaces.
1. Estimate the total weight of the fireplace
system including chimney and surround materials such as brick, stone, etc., to be installed. Shipping weights for the fireplace may
be found on page 18.
2. Measure the square footage of the floor
space to be occupied by the system, surrounds
and hearth extensions.
3. Note the floor construction, i.e. 2 x 6’s, 2 x 8’s
or 2 x 10’s, single or double joists, type and
thickness of floor boards.
4. Use this information and consult your local
building code to determine if you need additional support.
CAUTION: DO NOT BLOCK THE HEAT-CIRCULATING AIR INLET AND OUTLET PORTS ON
CIRCULATING MODELS. DOING SO MAY RESULT IN A POTENTIAL FIRE HAZARD.
If you plan to raise the fireplace and hearth
extension, build the platform assembly then
position fireplace and hearth extension on top.
Secure the platform to the floor to prevent
possible shifting.
CLEARANCES
Minimum clearance to combustibles for the
LA41 fireplace is as follows; sides and back –
2" (51mm), combustible floor – 0" (0mm),
adjacent wall 20" (508mm), adjacent shielded
wall (
K factor of .54 or less 24" W x 36" H
(356mm), ceiling – 37 ¹⁄₂" (953mm).
Note: Clearance at the nailing flange for both
fireplace models is 0" (0mm).
Note: Adjacent wall considerations are for an
adjacent wall on only a single side. Walls
should not be placed at minimum distance at
both sides of the fireplace.

The safety strips should extend from front of
the fireplace at least 1 ¹⁄₂" and should extend to
be at least flush with the sides. In the event a
wooden support is used to elevate the fireplace
above the floor, a “Z” type safety strip should be
fabricated and used to protect the front surface
of the wood support as well as the floor beneath
the hearth extension (
Figures 8 and 9
). The
safety strips should be tacked down to prevent
possible movement.
Note: The “Z” type safety strip is not supplied.

Note: The nailing tabs and the area directly
behind the nailing tabs are exempt from the
clearances described on page 5. Maintain at
least 1/2" clearance from the firebox wrapper to
the framing at the closest point of contact,
directly adjacent to the flange.
INSTALLING THE CHIMNEY SYSTEM
Step 1. Before continuing, check the operation
of the damper, as described on page 4, (
Figure 3
).
Step 2. Using standard construction framing
techniques, construct opening for chimney route
up through the ceiling(s) and roof or through an
outside chase.
Framing must maintain adequate minimum air
space clearance at all times.
CAUTION: ALLOW MINIMUM 2" CHIMNEY
AIR SPACE TO COMBUSTIBLE FRAMING MEMBERS THROUGHOUT VERTICAL OR OFFSET
CHIMNEY INSTALLATION.
refer to
Figure 18
Step 3. Position appropriate firestop spacer at
ceiling and nail temporarily with two (2) 8d
nails. Use flat firestop spacer, Model F10FS-2,
if chimney penetrates ceiling vertically. If chimney penetrates ceiling at 30° angle (offset
chimney), use 30° firestop spacer, Model
F10FS30-2. Use one nail on opposite sides to
hold firestop spacer in position. Nail permanently, using at least two (2) more 8d nails,
after chimney sections have been assembled
through the firestop spacer and after any necessary adjustments have been made. Firestop
spacer must be secured by at least four (4) 8d
nails when completely installed.
Note: If there is a room above ceiling level,
firestop spacer must be installed on the bottom
side of the ceiling. If an attic is above ceiling
level, firestop spacer must be installed on top
side of ceiling joist (Figures 19 and 20 ).
Room Above
CHIMNEY 30° OFFSET THROUGH FLOOR
OR CEILING
It may be necessary to assemble the chimney at
30° when passing through the floor or ceiling
area. Use the F10FS30-2 firestop spacer as
shown in
chimney at floor or ceiling penetration with a
FTF10 stabilizer if distance of chimney below
ceiling is 10' or more. Maintain 2" minimum air
space to combustibles from chimney sections.

Note:
Chimney sections are constructed
with a unique locking tab design, which ensures an immediate, tight assembly between
sections. Plan your chimney requirements carefully before assembly as chimney is difficult to
disassemble after installation. If disassembled,
the tabs might become damaged. Be certain
tabs are properly formed to ensure locking tabs
engage properly.
Security Chimneys FTF10 chimney system is a
two piece chimney, which snap together from
the fireplace up. Start with the inner flue section
with the lanced end up, snap lock it in to the
matching collar on top of the fireplace. At all
subsequent joints, the upper flue section fits
into the preceding flue section. Each piece
snaps together by means of locking tabs (9
locking tabs per joint). Check each piece by
pulling up slightly from the top to ensure proper
engagement before installing the next section.
If the flue has been installed correctly, it will not
separate when you test it. Also, the inner flue
joint where each section is joined should be
tight and flat without gaps (
Figure 23
).
Figure 23
Outer pipe section installs in just the opposite
way; the lanced end goes down and each new
section goes OVER the outside of the previous
section installed (
Figure 24
).
Locking
Tabs
(Lances)
Note: Assemble one component of chimney at
a time (inner section first, then outer section
last) before proceeding with the next complete
section.
Continue to assemble the chimney up through
framed opening. Assemble just enough to penetrate the roof flashing openings (
Figure 25
).
Always maintain 2" minimum air space to combustible materials and always check each chimney joint (inner and outer) to ensure proper
engagement. Check vertical alignment of chimney so that it projects from the roof in true
vertical position.

To Combustibles
Figure 25
Security's chimney sections do not need to be
screwed together. Additional reinforcement is
not necessary except in certain offset conditions (refer to page 12,
Figure 36
).
Step 5. The height of vertical chimney pipe
supported only by the fireplace must not exceed 30'. Chimney heights above 30' must be
supported by a Model FTF10-S4 stabilizer installed at 30' intervals.
Note: The Model FTF10-S4 adds 3" net effective
height to the total chimney system.
Install the Model FTF10-S4 stabilizer by fitting
inner section down into respective section of
proceeding flue pipe and locking outer stabilizer section into place over the outer chimney
pipe. Position for proper clearance through
framed opening and nail straps securely (under
tension in “shear”) into place on framing. Use
8d nails. Attach successive lengths of chimney
pipe directly to stabilizer using same techniques as described in Step 4 (
Figure 26
).
Note: Do not apply excessive pressure to any
subsequent chimney sections following the
stabilizer when installing. Ensure each subsequent chimney section is securely attached by
testing as noted in Step 4.
Step 6. Select the proper Security Chimneys
roof flashing based on pitch of roof. Use chart
below for selection:
Roof Pitch Model
Flat to 6/12 F10F6
6/12 to 12/12 F10F12
Next, slide roof flashing over extended chimney
section that previously has been installed above
the roof opening in Step 4. FTF10 flashings
require flashing spacers. Slide flashing all the
way down until the flashing base rests flat on
the roof (
Figure 27
). Again, check the vertical
position of the chimney and the 2" minimum air
space to combustibles.

If shingled roof, slide upper end and sides of
roof flashing under shingles (trim if necessary), seal the top and both sides of the flashing
to the roof with roof caulking. Cover nail heads
with roof caulking (
Figure 28
).

Step 8. The standard Security Chimneys FTF10
roof flashing assemblies include a storm collar.
Slide the storm collar over outer chimney, rest
on flashing spacers and align with top surface
of flashing. Insert tab in slot, pull tight and bend
tab back over slot. Seal storm collar to outer
chimney with roof caulking or mastic around
entire circumference of pipe. Also add extra
roof caulking to the tab/slot area to seal completely against water penetration (
Figure 29
).
Check all joints very carefully to ensure no
water intrusion can take place.

Step 9. Security Chimneys locking bands,
Model FLB, may be required if the chimney
extends too high above the roof flashing. As a
general rule, if the chimney extends more than
6' above the roof flashing, the use of locking
bands is advisable to strengthen the chimney
assembly. Align the locking band at the chimney joint. Locking bands wrap around pipe
joints equally covering the joints of both pipe
sections. Use the nut provided and TIGHTEN
snugly. Do not overtighten as this might damage the chimney section (
refer to Figure 29
).
Note: If chimney extends more than 8' above
roof surface, guy wires are also recommended.
Use three (3) guy wires, attach to locking band
assembly, extend and secure to roof in a triangular pattern (Figure 30 ). Guy wires are not
supplied by the manufacturer.

Min
Refer to specific installation instructions included with FTF10-CT2 chase terminations for
clearance and installation details.
Note: It is recommended that all exterior exposed metal fireplace components; such as
terminations, flashings, storm collars and/or
flue be painted with a premium quality, high
temperature, rust preventative paint designed
for metal. This is especially important when
installations are made in abnormally adverse or
corrosive environments; such as near lakes,
oceans or in areas with consistently high humidity conditions. Consult the paint manufacturers instructions for proper preparation and
application.
TEN FOOT RULE SUMMARY
The minimum chimney height above the roof
and/or to adjacent walls and buildings is specified by all major building codes.
If the horizontal distance from the peak of the
roof is less then 10', the top of the chimney
must be at least 2' above the peak of the roof.
If the horizontal distance from the chimney
edge to the peak of the roof is more than 10' a
chimney height reference point is established
on the roof surface 10' horizontally from the
chimney edge. The top of the chimney must be
at least 2' above this reference point. In all
cases, the chimney cannot be less then 3'
above the roof at the edge of the chimney.
The 2' in 10' rule is necessary in the interest of
safety but does not ensure smoke-free operation. Trees, buildings, adjoining roof lines, adverse wind conditions, etc., may require a taller
chimney should the fireplace not draft properly
(
see Figure 32

MULTIPLE TERMINATIONS
If more than one termination is located in the
same chase or within the same general proximity, we suggest they should be separated in
distance at least 24" horizontally from flue center to flue center and stacked or staggered
vertically at least 18" apart, from the termination of one smoke exit to the termination of
another smoke exit (
Figure 33
).
This suggestion is provided in the interest of
better operation. If the terminations are located
too close to each other, smoke may migrate
from one flue into the other.

CALCULATIONS
The minimum installed height of the completed fireplace system is 15' 0". The maximum height is 60' 0".
To determine the number of chimney sections
and chimney components required, follow
these steps:
1. Determine total vertical height of the fireplace installation. This dimension is the distance from the surface the fireplace sets on
to the point where smoke exits from the
termination.
2. Determine the number of chimney components required, except chimney sections. This
would include firestop spacers, stabilizers, roof
flashing, etc.
3. The effective heights of the components are:
The Fireplace = 52"
FTF10-12 = 10 ¹⁄₄"
FTF10-18 = 16 ¹⁄₄"
FTF10-36 = 34 ¹⁄₄"
FTF10-CTD Termination = 4"
FTF10-CT1 Termination = 12" to 18"
FTF10-CT2 Termination = 15" to 23"
FTF10-CTDT Termination = 12" to 18"
FTF10-S4 Stabilizer * = 3"*
* Required for every 30' of vertical chimney
and/or 10' of offset chimney.
4. Determine amount of chimney height required by subtracting total combined height of
all pre-selected components (fireplace and
chimney components from total desired height.)
Reference Vertical Elevation Chart and determine the number of chimney sections (quantity
and length) required.
SPECIAL OFFSET INSTRUCTIONS
To clear any overhead obstructions, you may
offset your chimney system using Security
Chimneys 30° offset and return elbows. Use
two elbows - an offset elbow to initiate the
offset and a return elbow to terminate it. A 30°
offset elbow, angling in any direction, may be
the first component used off the top of the
fireplace flue collar.
The offset and return elbows may be attached
together, or a section or sections of chimney
may be used between, but do not exceed 20' in
total length between elbows. If sections of pipe
exceed 10' between elbows, a chimney stabilizer must be used at the midpoint (
The stabilizer support straps must be attached
under tension (in shear) to structural framing
members above. When two sets of elbows are
used, the maximum combined length of chimney used between elbows cannot exceed 20'
(
Figure 35
). Example: If C1 = 10' then C2 cannot
exceed 10'.
If an offset exceeds 6' in length, each chimney
joint beyond the first 6' of offset to the return
elbow, must be secured by a No. 8 x ¹⁄₂" sheet
metal screw located at the underside of the
joint (
Figure 36
).
Figure 34
A ¹⁄₈" diameter hole must be drilled in the
chimney joint using a ¹⁄₈" diameter drill. Hole
should be drilled in center of joint overlap
Figure 37
(
). Be sure to drill only through the
outer chimney casting. Do not puncture the
inner flue.
Maximum offset of chimney system is 30°.
Two offsets must not be assembled to form a
60° offset. However, two sets of offset and
return elbows may be used on a single flue
system, provided the total height of the system exceeds 25'.
Return elbow support straps must be securely
attached under tension (in shear) to structural
framing members above. Do not substitute a
FTF10-30 offset elbow in place of a FTF10-E30
return elbow.
OFFSET CALCULATIONS
Step 1. Use Offset Chart to determine amount
of horizontal offset (A) and height (B) for
various chimney section assemblies.
Step 2. Use “Height of Chimney Only” column
in The Vertical Elevation Chart to determine
combinations of chimney used above return
elbow to achieve desired heights. Reference
Components Effective Height Chart in vertical
elevation chart section.
Step 3. Use Elevation Chart as job estimator
only. Add necessary firestop spacers and stabilizers as required. Firestop spacers must be
used as shown in
stabilizers as shown in
).

INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 38
Step 1. Determine the offset distance where
chimney is to pass through the first ceilingdimension “A.” To find this point on your ceiling, first determine the center point for a vertical chimney following the instructions for vertical installation.
for reference.
B
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Measure height to the ceiling from the top of
fireplace-dimension “B.” Use the appropriate
Offset Elevation Chart to find dimension “A.”
Mark point where you will drive your nail to
show the center point for your offset ceiling cut.
Step 2. Proceed by using the Straight Up Installation Instructions for cutting and framing ceiling and roof openings.
13
Note: See Framing and Dimension Chart for the
sizes of the ceiling and roof openings. The size
of the roof opening varies with the degree of
pitch of the roof.
Offset Elbow Assembly
Offset elbows install the same as chimney
sections. First, snap the inner section INTO the
preceding inner section of flue. Check connection by pulling up slightly to ensure a tight fit.
Next, the outer sections snap lock OVER the
preceding outer section of chimney. Again,
check outer section by pulling up slightly to
ensure proper connection is made.
Return Elbow Assembly
Return elbows install the same way as round
terminations and stabilizers:
Step 1. Hold return elbow over top of last
chimney section.
Step 2. Center inner slip section into inner flue
pipe-slip down.
Step 3. Center outer-locking section over outer
chimney pipe. Push down until locking joint has
firmly engaged.
Step 4. Pull up slightly on return elbow to
ensure locking joint has firmly engaged.
Step 5. Secure support straps to framing
members by nailing under tension in sheer
(
Figure 39
Figure 39
Note: The return elbow assembly performs
the same function as a stabilizer. Consider this
when determining the need for a stabilizer.
Note: Do not apply excessive pressure to any
subsequent chimney section following return
elbow assembly when installing. Ensure that
each subsequent chimney section is securely
attached by testing as noted above.

Combustion Air Kits
The installation of an outside combustion air
kit is highly recommended. It is very important to ensure good fireplace operation in
homes which are tightly weather sealed or
have ventilating appliances installed.
Step 1. Determine the source for outside air,
which can be installed through an outside wall
or into a ventilated crawl space. In either case,
a 4 1/2" diameter hole will be required for
installation of the air inlet assembly.
CAUTION: AVOID INSTALLING THE AIR INLET WHERE THE OPENING COULD BE
BLOCKED BY SNOW, BUSHES OR OTHER
OBSTACLES. THE MAXIMUM HEIGHT FOR
THE OUTSIDE AIR IS 50 FEET ABOVE THE
HEARTH, PROVING THE AIR INLET IS TERMINATED A MINIMUM OF THREE (3) FEET BELOW THE CHIMNEY CAP LEVEL.
Note: Combustion air inlet ducts must not
terminate in attic space.

OPTIONAL EQUIPMENT
CONSIDERATIONS
Gas Line Connection
Install a ¹⁄₂" gas supply line through fireplace
wall for connection to a decorative gas appliance inside the firebox. Outside, the gas supply
line connects to a gas shut-off valve recessed
flush into the wall or floor. The valve should be
controlled by a removable valve key for safety.
Always plumb gas line installation per local
codes. Check all connections with soap suds;
leaks will bubble. Never test any gas line connection with a match or open flame.
This provision is intended for connection to a
decorative gas appliance incorporating an automatic shut-off device and complying with the
Standard for Decorative Gas Appliances for
installation in vented fireplaces, ANSI Z21.60
(1991) or American Gas Association draft requirements for Gas-Fired Log Lighters for Wood
Burning Fireplaces, Draft No. 4 dated August,
1993. Install in accordance with the National
Fuel Gas Code, ANSI Z223.1. This complies
with the revised U.L. 127 standard.
Vent Free Appliances
These units have been tested and approved to
ANSI/IAS/AGA Z21.11.2 for use with unvented
gas appliances and complies with the standard for Factory-Built fireplaces, UL 127.
The unit has been tested for use with any
unvented gas log sets having a maximum
rating of 40,000 BTU. The minimum mantle
configurations are outlined in
Figure 42
.
14
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
These fireplaces have been marked with a
maximum rating of 40,000 BTU to assure that
homeowners do not exceed the allowable limits for all allowed installations of mantles.
NEVER INSTALL AN UNVENTED GAS LOG
SET WITH A BTU GREATER THAN 40,000.
CAUTION: WHEN USING THE DECORATIVE
GAS APPLIANCE, THE FIREPLACE DAMPER
MUST BE SET IN THE FULLY OPEN POSITION.
CAUTION: PLUMBING CONNECTIONS SHOULD
ONLY BE PERFORMED BY A QUALIFIED, LICENSED PLUMBER. MAIN GAS SUPPLY MUST
BE OFF WHEN PLUMBING GAS LINE TO FIREPLACE OR PERFORMING SERVICE.
If you’re installing a gas line, connect it before
the fireplace is framed and enclosed in the
finished wall. The gas knockout is determined
by the indentation located at the bottom and
slightly off center in the side refractories. THE
KNOCKOUT IS ALWAYS REMOVED FROM INSIDE THE FIREPLACE. DO NOT REMOVE THE
KNOCKOUT UNLESS YOU ARE INSTALLING A
GAS LINE. If removal is attempted from the
outer wrapper, side refractory damage may
occur. With a medium-sized hammer, lightly
tap the surface of the indentation. The refractory material is very thin in this area and is easily
removed. Once a small hole has been made,
continue tapping until you have reached sufficient diameter for the gas line to fit through. The
entire knockout does not have to be removed.
Remove insulation in the gas line channel.
IMPORTANT: REPACK INSULATION MATERIAL
IN SQUARE HOLE AROUND GAS LINE, INTERIOR AND EXTERIOR OF FIREPLACE, TO SEAL.
Glass Doors
If glass doors are to be installed on these
fireplaces, refer to specific installation instructions packed with the glass doors. Use only the
doors that are listed for use with these fireplaces. Use of other non-listed glass door on
these fireplaces may constitute a potential fire
hazard and is not recommended.
COLD CLIMATE INSULATION
If you live in a cold climate, it is especially
important to seal all cracks around the fireplace opening with noncombustible material
and wherever cold air could enter the room.
Surrounding materials must be caulked where
it meets the black metal facing of the fireplace
to avoid cold air intrusion. Use noncombustible caulking material only on fireplace facing
to seal. Also, the outside air inlet duct should
be wrapped with noncombustible insulation to
minimize the formation of condensation. Do
not place insulation materials on top of fireplace or against chimney sections.
Note: A 2" air space must be preserved for all
combustible materials extending for any continuous length adjacent to the chimney.
It is especially important to insulate between
the studs of an outside chase cavity and under
the floor if the floor is above ground level. Do
not place insulation directly against the fireplace or chimney system.
FIREPLACE FINISHES
Mantels and Trim
It is sometimes best to frame your fireplace

These fireplaces may sit directly on a combustible surface. A 2" air space is required between combustible framing and the chimney.
Combustible mantels and trim may be installed 12" above the fireplace opening as per
NFPA 211, Section 7-2.3.3. and
Figure 42
. If
a mantel is of a noncombustible material, it is
exempt from these requirements as long as it
does not interfere with the installation or operation of glass doors.
Hearth Extensions and Wall Shields
A hearth extension must be installed with
all fireplaces. It is to protect the combustible
floor in front of the fireplace from both
radiant heat and sparks. The hearth extension must extend beyond the front at
least 20" (508 mm) and both sides at least
12" (305 mm) (
Use a hearth extension constructed of a
durable noncombustible material having an
equal or better (lower k value) insulating

Note: Any noncombustible material whose k
value is less than .84 or whose r value is more
than 1.19 is acceptable.
If the fireplace is installed on a combustible
floor, use the metal safety strips (provided)
on the floor extending half under the fireplace and half under the hearth extension.
A wall shield is required where a continuous
perpendicular side wall is within 15" of the
fireplace opening (
see Figure 44 )
. Use a 40" W
x 40" H wall shield constructed of a durable,
noncombustible material having an equal or
better (lower k value) insulating value than k =
.84 BTU IN/FT2 HR °F. At no time may a
perpendicular side wall be located closer than
12" from the fireplace opening.
If fireplace is installed diagonally across a 90°
corner; no wall shields are required.

Methods of Determining Hearth Extension and Wall Shield
Equivalents - To determine the thickness required for the alternate
material when either the “k” value or “r” value is known, use either the
k formula or r formula.

Table 1
** If the hearth extension material(s) that is intended to be used is NOT listed
on Table 1, the material can still be used if the material(s) is noncombustible.
However, the manufacturer of the material must provide either the listed kvalue per inch or r-value per inch with listed thickness so that the minimum
thickness required for the hearth can be calculated (per instructions on this
Page and/or as specified in the NFI Certification manuals).
Note: Also see NFI (National Fireplace Institute) Certification Manuals showing
other acceptable calculation methods and acceptable alternate materials
which can be used.
At times it is important to know what
combination of materials are acceptable for
use as floor protection. The “R values” are
used to determine acceptable combinations of
materials because “R values” are additive where
r and k values are not.
“R value” = 1/k = “r” x thickness of material
used
Example:
Given that the required “R value”
for a suitable floor protector used must be
equal to or greater than:
x TL = 1.19 x 1” = 1.19.”
“R” = r
L
If it is desired to elevate a marble hearth extension to a level of 5” or more above the floor
surface. What combination of noncombustible materials can be used to accomplish this?
If common brick is used so that the 3 1/2”
dimension is the height, “R” for the common
brick becomes:
brick
“R”M = rM x TS = 0.20 x 3 1/2" = .70
Using 1/2” of mortar to set the brick, “R” for
the mortar is calculated as follows:
mortar
“R”M = rM x TS = 0.20 x 1/2" = .10
Next, a 3/4" marble slab set in 1/2" mortar covers the brick, “R” for the marble and mortar
becomes:
marble
“R”M = rM x TS = 0.05 x 3/4" = .038
mortar
“R”M = rM x TS = 0.20 x 1/2" = .10
The sum of all “R values” is: .70 + .10 +. 038
+ .10 = .938
This would NOT be an acceptable combination
of material for the hearth extension since the
total calculated “R value” of the materials used
is under the required “R value” of 1.19. An
additional layer of insulating materials must
be used.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Note:
Also see NFI Certification Manuals for
expanded explanation on calculating “R values” when multiple materials are used.

Example: Given that the required “R value” for
a suitable hearth extension used must be equal
to or greater than:
“R” = r x T
= 3.70 x 1" = 3.70.

INSTALLATION COMPONENTS
The following items are available for use in the
installation of this appliance.
7 ¹⁄₂"
If common brick is used so that the 3 ¹⁄₂"
dimension is the height, “R” for the common
brick becomes:
“R”M = r x TM = 0.20 x 3 ¹⁄₂" = .70
Using ¹⁄₂" of mortar to set the brick, “R” for the
mortar is calculated as follows:
“R”M = r x TM = 0.20 x ¹⁄₂" = .10
A ³⁄₄" marble slab set in ¹⁄₂" mortar covers the
brick, “R” for the marble and mortar becomes:
“R”M = r x TM = 0.09 x ³⁄₄" = .068
“R”M = r x TM = 0.20 x ¹⁄₂" = .10
The sum of all “R values” is:
.70 + .10 +. 068 + .10 = .968
This would not be an acceptable combination
of material for the hearth extension since the
total calculated “R value” of the materials used
is under the required “R value” of 3.70. An
additional layer of insulating materials must
be used.
WARNING: THE CRACK BETWEEN THE
FIREPLACE AND THE HEARTH EXTENSION MUST BE SEALED WITH A NONCOMBUSTIBLE MATERIAL.
WARNING: WHEN INSTALLING HEARTH
EXTENSION IN FRONT, THE FIREPLACE
MUST BE RAISED IF HEIGHT OF HEARTH
EXTENSION EXCEEDS 7 ¹⁄₂" ABOVE THE
BOTTOM OF FIREPLACE (

FINISH TO YOUR TASTE
There are a wide variety of “finished looks” for
these fireplaces, from formal wall decor with
elaborate mantels to rustic wood paneling or
warm brick facings.
Only noncombustible materials like stone, tile,
brick, etc., may overlap the black front facing.
Do not extend these materials beyond the black
facing and into the firebox area. Be sure not to
interfere with the installation and operation of
glass doors or block the upper or lower grilles.
Seal all joints between the black facing and wall
surrounds to prevent air intrusion. Use noncombustible caulking material only to seal the
black metal facing to the surround material on
the finished wall.
Combustible materials may project beyond the
sides of the fireplace opening as long as they
are kept within the shaded areas illustrated in
