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" (250 mm) 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 chemical
chimney cleaners or flame colorants in your
fireplace.
Never burn treated construction lumber or
scraps. These woods burn excessively hot
and may contain chemicals used to treat
insects and fungus. When burned, these
chemicals can pose a significant hazard.
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.
IMPORTANT: WHEN INSTALLING IN CANADA,
THE CHIMNEY AIR KIT MUST BE INSTALLED
PER THE WARNOCK HERSEY INC. LISTING.
IMPORTANT: THE MINIMUM AIR SPACE TO
COMBUSTIBLES FOR THE CHIMNEY SYSTEM
IS 2" (51 MM).

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 (
Push back and up (away from the front of the
fireplace) to lock the damper blade in the
OPEN position. To lock the damper in the
CLOSED position, the damper handle needs
to be pulled forward and up (towards the
front of the fireplace).

sequence.
1. Position firebox prior to framing or into
prepared framing.
2. Install chimney air kit (Canada only).
3. Install the chimney system.
4. Install optional outside combustion air kit.
5. Plumb gas line if a decorative gas appliance
will be used. (Gas connections should only be
performed by an experienced, licensed/certified tradesman.)
6. Complete the installation, finish wall material, surround and hearth extension to your
individual taste.
7. 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.
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 17.
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
Colonial fireplace is as follows; sides and back
– 1" (25.4 mm), combustible floor – 0" (0 mm),
adjacent wall 18" (457 mm), adjacent shielded
wall (
K factor of .84 or less 24" W x 36" H
(305 mm), ceiling – 37 ¹⁄₂" (953 mm).
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.
) 12"
INSTALLING THE FIREPLACE
Step 1. Slide the fireplace into prepared fram-
ing or position fireplace in its final position and
frame later.
Step 2. Insert the metal safety strips, packaged
with the fireplace, beneath the fireplace as
illustrated (

Step 5. 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 or equivalent (
Framing Stud
Figure 18
Nailing Tab
8d Nail
).
Figure 18
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
Proceed with Steps 6–9
Step 6. Remove one of the knockouts from the
fireplace transition and attach the 4" (102 mm)
collar from the air kit to the transition with four
(4) No. 8 x ¹⁄₂" screws provided (
Figure 19
Optional
Connection
).
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"
(457 mm) above the attic floor. Secure the duct
hood to a vertical post with the inlet positioned
downward. Ensure nothing blocks the hood
opening. This air duct must never terminate
higher than the chimney.
Step 9. Cut or frame hole through the outside
wall for the installation of the duct inlet hood. A
4 ¹⁄₂" (114 mm) diameter hole is sufficient. Feed
the loose end of the flexible duct through the
hole cut for the inlet hood and attach to collar on
inlet hood using two (2) No. 6 x ³⁄₈" screws
provided. Insert hood into opening. Secure
hood in place with the No. 8 x 1 ¹⁄₂" screws
provided or with nails driven through holes in
hood flange. Seal with noncombustible waterproof silicon type caulking. If additional duct is
needed, use Class 0 metallic duct.
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
Plumb Line
Figure 20
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 (refer to page 14 and
and 43
). Use one nail on opposite sides to hold
Figures 42
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 ).
Room Above

Air Kit
Figure 19
Step 7. Connect the 4" (102 mm) Class 0 air
duct to the collar with two (2) No. 8 x ¹⁄₂" screws
provided in the hardware kit.
Step 8. Route the Class 0 air duct out the back
wall or side wall, up through the ceiling or floor
joists to an outside wall. The air duct should be
located above snow level.
8
A minimum 2" air space must be reserved for
all combustible materials extending for any
continuous length surrounding the chimney.
Reference
Figures 16 and 17
and charts Framing Dimensions for Ceiling and Roof, which
specify minimum ceiling and roof dimensions.
In new construction, to determine chimney center line, use plumb line from roof or ceiling above
fireplace to center of flue collar on fireplace.
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.

Firestop Spacer
Figure 22
For Canada Only
When installing the chimney system through
an open attic space, the attic shield assemblyfirestop spacer must be used (
installation procedure is Warnock Hersey Inc.
listed only for use in Canada.
Open Attic Space
Figure 23
). This
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 25
).
Locking
Tabs
(Lances)
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 27
).
Figure 23
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.
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 24
).
Figure 25
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 (

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.

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 28
). Again, check the vertical
position of the chimney and the 2" minimum air
space to combustibles.
Figure 24
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 38
).
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.

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 29
).
Figure 29
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 30
Check all joints very carefully to ensure no
water intrusion can take place.
Locking Band

Figure 30
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 30
).
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 31 ). Guy wires are not
supplied by the manufacturer.

Note: It is recommended that all exterior ex-
posed related metal fireplace components; such
as terminations, flashings, storm collars and/
or flue be painted with a premium-quality, hightemperature, 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.
For Canadian installations, all chimney installed
outside the building must be galvalume (outer
sections only), effective January 1, 1992. The
appropriate model designations (with a “C”
suffix) are located in the back of this manual.
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' (3 m), the top of the
chimney must be at least 2' (610 mm) above
the peak of the roof.
If the horizontal distance from the chimney
edge to the peak of the roof is more than 10'
(3 m), a chimney height reference point is
established on the roof surface 10' (3 m) horizontally from the chimney edge. The top of the
chimney must be at least 2' (610 mm) above
this reference point. In all cases, the chimney
cannot be less than 3' (914 mm) 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
).
10
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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" (610 mm) horizontally
from flue center to flue center and stacked or
staggered vertically at least 18" (457 mm) apart,
from the termination of one smoke exit to the
termination of another smoke exit (

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.
FTF10 CHIMNEY COMPONENT
CALCULATIONS
The minimum installed height of the completed
fireplace fireplace system is 16'0" (4.8 m). The
maximum system height is 80'0" (24.38 m).
Less Than 10' (3m)
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 compo-
).
nents required, except chimney sections. This
would include firestop spacers, stabilizers, roof
flashing, etc.
3. The effective heights of the components are:
The Fireplaces = 65 ¹⁄₄" (1657 mm)
FTF10-12 = 10 ¹⁄₄" (260 mm)
FTF10-18 = 16 ¹⁄₄" (413 mm)
FTF10-36 = 34 ¹⁄₄" (870 mm)
CTDTM Termination = 10" (254 mm)
CT2 Termination = 15" to 23"
(381–584 mm)
S4 Stabilizer * = 3" (76 mm)*
* Required for every 30' (9.1 m) 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'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 must not exceed
20' (6.1 m) in total length between elbows
(
Figure 36
m) 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' (6.1 m)
(
Figure 37
C2 cannot exceed 10' (3 m).
If an offset exceeds 6' (1.8 m) in length, each
chimney joint beyond the first 6' (1.8 m) 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 (
A ¹⁄₈" (13 mm) diameter hole must be drilled in
the chimney joint using a ¹⁄₈" (13 mm) diameter drill. Hole should be drilled in center of
joint overlap (
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 22' (6.7 m) (
Figure 42
).
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
Underside of Chimney
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

INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 40
for reference.
OPTIONAL EQUIPMENT
CONSIDERATIONS
Combustion Air Kits
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.
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.
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 41
).
Return
Elbow
Figure 41
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.
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.

Refer to installation instructions packed with
the air kit for specific installation information.
The outside air kit must be installed before the
fireplace is framed and enclosed in the finished walls.
Outside air drawn into the fireplace supplies air
to the fire for combustion. Only one combustion air duct on the left side of the fireplace is
necessary if installed (
Provision for
Outside Air
Figure 44
).
Figure 44
If additional length of duct is necessary, purchase locally available U.L. Class 0 or Class 1
metallic duct. The duct may extend up to 50'
(15.24 m) in any direction.
Note: When installing the air duct vertically,
DO NOT terminate the duct closer than 3'
(914mm) below the chimney top.
There is a one-hand operated shut-off valve
located in the left side of the fireplace opening
behind the screen. To open, rotate handle upwards. The handle should lock open at 45°.
The combustion air damper should be fully
open when the fireplace is in use and fully
closed when the fireplace is not in operation to
prevent outside air from entering your home.
CAUTION: NEVER LOCATE INLET WHERE IT
CAN BE BLOCKED BY SHRUBS, SNOW
DRIFTS, ETC. NEVER LOCATE INLET IN GARAGE OR ANY AREA WHERE THERE IS ANOTHER FUEL-BURNING APPLIANCE OR
PRODUCTS EMITTING COMBUSTIBLE GASES
SUCH AS PAINT, GASOLINE, ETC. IN COLD
CLIMATES IT IS RECOMMENDED THE COMBUSTION AIR DUCT BE INSULATED.
14
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Outside combustion air ducting may be run
upwards or vertically through framing and ceiling joists, with the hood installed through an
outside wall and 3' (914 mm) below the termination. Ducting may also be run downward
through floor joists and under the home to a
ventilated crawlspace not considered part of
the living area of the home.
Note: Do not terminate combustion air kit in
attic space under any circumstances.
FTF10-TMS Termination Shroud
An optional termination shroud is available to
partially conceal the FTF10-CTDTM when installed on a chase. Model FTF10-TMS is adjustable for chases measuring a minimum of 27" x
27" (686 mm x 686 mm) up to a maximum of
40 ¹⁄₂" x 40 ¹⁄₂" (1029 mm x 1029 mm). Consult
the FTF10-TMS installation instruction for specific installation information.
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.
GAS LINE CONNECTION
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.
Install a ¹⁄₂" (13 mm) 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.
IMPORTANT: RE-PACK INSULATION MATERIAL IN SQUARE HOLE AROUND GAS LINE;
INTERIOR AND EXTERIOR, TO SEAL.
This provision is intended only 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.
Install in accordance with the National Fuel Gas
Code, ANSI Z223.1. This complies with the
revised U.L. 127 standard.
CAUTION: WHEN USING THE DECORATIVE
GAS APPLIANCE, THE FIREPLACE DAMPER
MUST BE SET IN THE FULLY OPEN POSITION.
Vent Free Appliances
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 against chimney
sections.
Note: A 2" (51 mm) 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

The Colonial Series fireplaces have been approved to accept a ¹⁄₂" (13 mm) gas line for an
approved gas appliance. Always have the appliance installed by a qualified, licensed plumber
in accordance with all local building codes. The
gas line may enter either side of the fireplace.
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 a 1 ¹⁄₈"
(29 mm) round indentation located at the bottom
and slightly off center in the side refractories.
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
Figures 45 and 46
.
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.

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) (

that equals or exceeds r = 1.19 HR °F FT2/
BTU IN. With these values, determine the
minimum thickness/material required using
the formula and
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 12" of the
fireplace opening (

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.
Figure 48
Calculating Minimum Thickness if Multiple
Materials are 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
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
“R”M = rM x TS = 0.20 x 1/2" = .10
mortar
17
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:
Also see NFI Certification Manuals for
expanded explanation on calculating “R values” when multiple materials are used.

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
