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 FTF8 (8" 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 a 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 an that 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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.

The "C" models are designed as heat circulating
fireplaces and may be fitted with accessory
fans.
The BRI and BCI models are fully insulated for
installation in colder climates.

WARNING: MODELS THAT HAVE THE
"-2" SUFFIX HAVE NOT BEEN TESTED
WITH AN UNVENTED GAS LOG SET. TO
REDUCE RISK OF FIRE OR INJURY, DO
NOT INSTALL AN UNVENTED GAS LOG
SET INTO THIS FIREPLACE.
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. J99025865B-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.
These fireplaces have been tested for installation in Canada to ULC-S610. For installations
in Canada, the chimney clearance to combustibles must be 2 inches and the Cold
Climat Kit must be installed.

Hearth

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 in front of the firebox lintel (Figure 3 ).
The control lever snaps into place at either
extreme of its range of motion. When locked
in position all the way to the right, the damper
is open. When locked in position all the way to
the left, the damper is closed.

Optional
Outside Chase

Carefully consider the position of the fireplace
opening with respect to the location of adjacent or nearby stairwells, bath or kitchen exhaust fans and/or return air registers for forced
air furnaces/air conditioners that could cause
a smoking fireplace condition if the house is
tightly insulated.
When locating the fireplace, consideration must
be given to combustibles and final finishing.
See Figure 5 and confine the final location of
combustible finish materials to the "Safe Zone".
DO NOT permanently place furniture or other
items such as decorative pillows within 60" of
the fireplace front face.

individual taste.
7. Assemble and attach optional glass door
assembly.
Study the three dimensional illustration (Figure 1 ) to get a general idea of each element of
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.
Be sure fireplace rests on a solid continuous
floor or platform with appropriate framing for
support and so that no cold air can enter the
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:

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.

Step 4. Fireplace should be secured to side
framing members using the full length nailing
tabs at the top and bottom of the fireplace front
face. Use 8d nails (Figure 17 ).

Step 6. Connect the 6" (102 mm) Class 0 air
duct provided by installer, to the duct collar on
the fireplace and secure with two (2) screws
from the kit’s hardware package.

CAUTION: ALLOW MINIMUM 1"* CHIMNEY
AIR SPACE TO COMBUSTIBLE FRAMING MEMBERS THROUGHOUT VERTICAL OR OFFSET
CHIMNEY INSTALLATION.

Step 7. Route the Class 0 air duct out the back
or side wall, up through the ceiling or floor
joists to an outside wall. The air inlet hood
should be located above snow level or above
any anticipated snow level, (Figure 19 ).

A minimum 1"* air space must be reserved for
all combustible materials extending for any
continuous length surrounding the chimney.

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.

For Canadian Installations
A cold Climate Kit FTF8-CCK3-LD must be
installed. CCK3 kits are available from
FireCraft through your local dealer. Installer
must supply suitable length of 6" Diameter,
class "0" metallic air duct.

Proceed with Steps 5 through 8
Step 5. Install the Cold Climate Kit to the
fireplace following the instructions provided
with the kit, (Figure 18 ).

Figure 19
Note: If the fireplace is installed against an inside
wall, the class 0 air duct may be extended into a
ventilated attic space at least 18" (475mm) above
the attic floor. Secure the air inlet hood to a
vertical post with the inlet positioned downward.
Ensure that nothing blocks the hood opening.
This hood must never terminate higher than
three (3) feet below the termination.
Step 8. Cut or frame a hole through the outside
wall for the installation of the air inlet hood. A 61/2" diameter hole is required. Feed the loose
end of the flexible duct through the hole and
attach to the collar on the air inlet hood using two
(2) screws from the kit's hardware package.
Insert the hood into the opening. Secure the inlet
hood in place with nails driven through the holes
in the flange. Seal with noncombustible waterproof silicon type caulking.

INSTALLING THE CHIMNEY SYSTEM
Step 1. Before continuing, check the operation
of the damper, as described on page 4, (refer to
Figure 3 ).

Figure 18

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.

For remodeling, plumb to center of flue collar
from ceiling above, drive nail through ceiling
from below to mark position, then mark and cut
to passage from above ceiling (around nail)
(Figure 20 ). Then plumb from ceiling or roof
level directly above hole which has just been
completed.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Figure 20
Step 3. Position appropriate firestop spacer at
ceiling and nail temporarily with two (2) 8d
nails. Use flat firestop spacer, Model F8FS-2, if
chimney penetrates ceiling vertically. If chimney penetrates ceiling at 30° angle (offset chimney), use 30° firestop spacer, Model F8FS30.
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 21 and 22 ).

in Figures 23 and 24. Support the chimney at
floor or ceiling penetration with a FTF8 stabilizer if distance of chimney below ceiling is 10'
or more. Maintain 1"* minimum air space to
combustibles from chimney sections.

*Note: 2" clearance to combustibles required
in Canada.

Note: For Canadian installations, all chimney
installed outside the building must be constructed
with galvalume (outer sections only) effective
January 1, 1992. The appropriate model designations are located in the back of this manual.
Step 4. 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.
The Security Chimneys FTF8 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.

Figure 27
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 28 ).
Always maintain 1"* 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Security's chimney sections do not need to be
screwed together. Additional reinforcement is
not necessary except in certain offset conditions (refer to page 14, Figure 39 ).
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 FTF8-S4 stabilizer installed at 30' intervals.

Note: The Model FTF8-S4 adds 3" net effective
height to the total chimney system.
Install the Model FTF8-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 29 ).

Next, slide roof flashing over extended chimney
section that previously has been installed above
the roof opening in Step 4. FTF8 flashings
require flashing spacers. Slide flashing all the
way down until the flashing base rests flat on
the roof (Figure 30 ). Again, check the vertical
position of the chimney and the 1"* minimum
air space to combustibles.

Step 7. Secure flashing by nailing along the
perimeter into roof using 8d nails. 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 31 ).

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 32 ).

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 33 ). Guy wires are not
supplied by the manufacturer.
Roof Ridge

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:

Step 8. The standard Security Chimneys FTF8
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
32 ). Check all joints very carefully to ensure
no water intrusion can take place.

Step 10. Using a FTF8-CTD Round Termination:
1. Hold the FTF8-CTD over top of last chimney
section (see Figure 34 ).
2. Center inner slip section in inner flue pipeslip down.
3. Center outer locking section over outer flue
pipe. Push down until locking tabs are firmly
engaged.

Using a FTF8-CTDT Chase Termination:
Refer to specific installation instructions included with the FTF8-CTDT chase termination
for clearance and installation details.
Using a FTF8-CT1 Chase Termination:
Refer to specific installation instructions included with FTF8-CT1 chase terminations for
clearance and installation details.
Using a FTF8-CT2 Chase Termination:
Refer to specific installation instructions included with FTF8-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.

Figure 35
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 35 ).

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 36 ).

TEN FOOT RULE SUMMARY

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.

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:

CTDT

The minimum chimney height above the roof
and/or to adjacent walls and buildings is specified by all major building codes.

The minimum installed height of the completed fireplace system is 15' 0". The maximum height is 60' 0".

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

* 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.

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 Figures 23 and 24 and
stabilizers as shown in Figure 29.

FTF8 VERTICAL ELEVATION CHART

SPECIAL OFFSET INSTRUCTIONS
To clear any overhead obstructions, you may
offset your chimney system using Security's
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 (Figure 37 ).
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 38 ). 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 39 ).
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 40 ). 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
FTF8-30 offset elbow in place of a FTF8-E30
return elbow.

The FBK-100/200 Blower Kits are design certified by Warnock Hersey for use with these
appliances.

To operate, push the end of the actuator to the
left as shown in Figure 45, until it "pops" free of
its "locked" position. Pull the actuator forward
to open the combustion air door, and push it
back to close. To "lock" the combustion air
door closed, ensure the actuator is pushed all
the way back then push the end of the actuators to the right until the step in the actuator
moves behind the appliance front face within
the slotted opening.

Always check local building codes. Installation
of the FBK Blower Kits must comply with local
regulations as well as the National Electric
Code.

Combustion Air Kits
These appliances are equipped with an outside
(make-up) air door and integral actuator arm. If
the appliance is to be installed with an outside
air vent system, use only FireCraft Models
FAOK or FAOK-LD Combustion Air Kits. These
kits come complete with detailed installation
instructions and all components necessary in
completing a combustion air vent system.
After completing the installation of the optional
combustion air vent system the actuator arm
must be put in service and tested to ensure
proper operation before completing any enclosure around the firebox. Failure to do so may
result in extensive and costly rework.

WARNING: DO NOT REMOVE THE ACTUATOR ARM LOCKING SCREW UNLESS
THE COMPLETE OUTSIDE AIR VENT SYSTEM HAS BEEN INSTALLED IN ACCORDANCE WITH THE DETAILED INSTRUCTIONS PROVIDED WITH THE KIT.
Locate the actuator arm along the right side of
the appliance firebox opening and refer to
Figure 45. After completing the installation of
the Outside Combustion Air Kit remove and
discard the actuator arm locking screw.

Operate the actuator through several cycles
including the "lock position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the locked position.

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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Log sets with 40,000 BTU may be installed
provided that no combustible mantle projections are placed lower than 18 inches from the
fireplace opening.
These fireplaces have been marked with a
maximum rating of 32,000 BTU to assure that
homeowners do not exceed the allowable limits for all allowed installations of mantles. That
limit may be increased to 40,000 BTU, provided that the mantle installed complies with
the 18-inch limitation and a copy of these
instructions are available.
NEVER INSTALL AN UNVENTED GAS LOG
SET WITH A BTU GREATER THAN 32,000 IF
COMBUSTIBLE MANTLE PROJECTIONS ARE
LOWER THAN 18 INCHES ABOVE THE FIREPLACE OPENING.

WARNING: MODELS THAT HAVE THE
"-2" SUFFIX HAVE NOT BEEN TESTED
WITH AN UNVENTED GAS LOG SET. TO
REDUCE RISK OF FIRE OR INJURY, DO
NOT INSTALL AN UNVENTED GAS LOG
SET INTO THIS FIREPLACE.
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.
CAUTION: CERTAIN GLASS DOORS OVERLAP
THE BLACK METAL FACING OF THE FIREPLACE. IF THE FIREPLACE HAS BEEN FACED
WITH NONCOMBUSTIBLE MATERIALS, THERE
MIGHT NOT BE SUFFICIENT CLEARANCE TO
INSTALL THE GLASS DOORS OF YOUR
CHOICE. ENSURE ADEQUATE CLEARANCE IS
MAINTAINED AT ALL TIMES SO AS NOT TO
INTERFERE WITH THE INSTALLATION AND
OPERATION OF GLASS DOORS.

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.

Note: A 1"* air space must be preserved for all
combustible materials extending for any continuous length adjacent to the chimney.

FIREPLACE FINISHES

Combustible
Mantel
and Trim

Mantels and Trim
It is sometimes best to frame your fireplace
after it is positioned and the chimney is installed. Frame enclosure for chimney and fireplace with 2 x 4’s (or heavier) lumber.

Note: The header may rest on the two (2) metal
top spacers on top of the unit but the header
must not be notched to fit around the spacers.
These fireplaces may sit directly on a combustible surface. A 2" air space is required between combustible framing and the chimney.
A 1" air space is required between combustible
framing and fireplace outer wrapper. In Canada,
the minimum height for a combustible mantel
is 18" (457 mm) above the fireplace opening.
Figure 46 shows typical Canadian installations. For installations other than Canada,
combustible mantels and trim may be installed 12" above the fireplace opening as per
NFPA 211, Section 7-2.3.3. and Figure 47. 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.

*Note: 2" clearance to combustibles required
in Canada.
Finished
Wall

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.

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 8" beyond both sides of the fireplace
opening and 16" beyond the front (Figure 48 ).
Use a hearth extension constructed of a durable noncombustible material having an equal
or greater insulating value of k = .43BTU IN/FT2
HR °F or a thermal resistance that equals or
exceeds r = 2.33 HR °F FT2/BTU IN. With these
values, determine the minimum thickness/
material required using the formula and the
Table on page 17.

Note: Any noncombustible material whose k
value is less than .43 or whose r value is more
than 2.33 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 (refer to Figures 6 and 7 ).
A wall shield is required where a continuous
perpendicular side wall is within 12" of the
fireplace opening, (Figure 49 ). Use a 36" x 36"
wall shield constructed of millboard or a durable, noncombustible material having an equal
or greater insulating value than K = .54BTU IN/
FT2 HR °F. At no time may a perpendicular side
wall be positioned closer than 9 inches.

If fireplace is installed diagonally across a 90°
corner; no wall shields are required.

Example: Given that the required “R value” for
a suitable hearth extension used must be equal
to or greater than:
“R” = r x TL = 2.33 x 1" = 2.33.
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?

TM (inches) = 2.33 x TL
rM

If common brick is used so that the 3 ¹⁄₂"
dimension is the height, “R” for the common
brick becomes:

TM (inches) = 2.33 x 1"
2.33*

“R”M = r x TM = 0.20 x 3 ¹⁄₂" = .70

Answer using r = 1 x 1" = 1 =
1" thickness Micore will be required.
At times it is important to know what combination of materials are acceptable for use as
hearth extensions. The “R values” are used to
determine acceptable combinations of materials because “R values” are additive where r and
k values are not.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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

*value taken from chart

A ³⁄₄" marble slab set in ¹⁄₂" mortar covers the
brick, “R” for the marble and mortar becomes:

INSTALLATION COMPONENTS
The following items are available for use in the
installation of this appliance.

“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:

5 1/2"

.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 2.33. An
additional layer of insulating materials must
be used.

Figure 51

WARNING: THE CRACK BETWEEN THE
FIREPLACE AND THE HEARTH EXTENSION MUST BE SEALED WITH A NONCOMBUSTIBLE MATERIAL.

Secure the hearth extension to the floor to
prevent possible shifting.

WARNING: WHEN INSTALLING HEARTH
EXTENSION IN FRONT OF A NON-CIRCULATING FIREPLACE MODEL, THE FIREPLACE MUST BE RAISED IF HEIGHT OF
HEARTH EXTENSION EXCEEDS 7" ABOVE
