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" (254mm) 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
The LBR Series fireplace is a traditional wood
burning radiant heat system. The LBC Series
fireplace is a traditional wood burning heat
circulating system. These fireplaces come with
standard bar grates, optional outside combustion air kits and optional decorative glass doors.
TYPICAL INSTALLATION
Note: Illustrations shown reflect “typical” instal-
lations 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. 629-915173A)
to U.L. standard 127 for US and ULC S610 for
Canada. These units are intended for installation in residential homes and other buildings
of conventional construction including commercial, not in mobile homes.
These fireplace systems are designed for installation in accordance with the National Fire
Protection Standard for chimneys, fireplaces
and solid fuel burning appliances; NFPA 211
and in accordance with codes such as the
BOCA Basic/National Codes, the Standard Mechanical Code and the Uniform Building Codes.
WARNING: FAILURE TO USE MANUFACTURE PROVIDED PARTS, VARIATIONS IN
TECHNIQUES AND CONSTRUCTION MATERIALS OR PRACTICES OTHER THAN
THOSE DESCRIBED IN THIS MANUAL
MAY CREATE A FIRE HAZARD AND VOID
THE LIMITED WARRANTY.
IMPORTANT: WHEN INSTALLING THESE
FIREPLACES IN CANADA, THE CHIMNEY

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 bottom left side, just behind the firebox screen
(
Figure 3
at the extreme range of motion, up and back in
the closed position. When pulled forward and
down, the damper is open.
). The control lever snaps into place
Figure 3
LOCATION OF FIREPLACE
Carefully select the proper location for heat
circulation, aesthetics, chimney obstructions
and clearance to side wall(s). With proper preplanning, a slight adjustment of a few inches
can save considerable time and expense later
during construction and assembly.

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:
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
fireplace is as follows; sides and back – 1/2"
(13mm), combustible floor – 0" (0mm), adjacent wall 18" (457mm), adjacent shielded wall
(
K factor of .84 or less 40" W x 40" H
(305mm), ceiling – 37-1/2" (953mm).

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.

Step 4. The fireplace should be anchored to the
floor. Bend down the four (4) anchor tabs
located at the base of the fireplace and secure
to the floor with 8d nails (
Figure 17
Anchor
Tab
).
Step 7. Connect the 4" (102 mm) Class 0 air
duct provided, to the collar on the chimney
collar enclosure with the screws provided in the
kit’s hardware package.
Step 8. Route the Class 0 air duct out the back
or side wall, up through the ceiling or floor
joists to an outside wall. The duct inlet should
be located above snow level or above any
anticipated snow level.
Step 2. Using standard construction framing
techniques, construct openings for the chimney through the ceiling(s) and roof or through
an outside chase. All framing must maintain the
minimum air space clearance at all times.
CAUTION: ALLOW A MINIMUM 2" (51 MM)
CHIMNEY AIR SPACE TO COMBUSTIBLE FRAMING MEMBERS THROUGHOUT VERTICAL AND/
OR OFFSET CHIMNEY INSTALLATIONS.

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 that nothing blocks the hood
opening. This duct must never terminate higher
than the fireplace chimney.
Step 9. Cut or frame a hole through the outside
wall for the installation of the duct inlet hood. A
4-1/2" (114 mm) diameter hole is required.
Feed the loose end of the flexible duct through
the hole cut for the inlet hood and attach to the
collar on the inlet hood using (2) two screws.
Insert the hood into the opening. Secure in
place with nails driven through the holes in
hood flange. Seal with noncombustible waterproof silicon type caulking. If additional duct is
needed, use Class 0 metallic air duct.
A minimum 2" (51 mm) air space must be
reserved for all combustible and noncombustible materials extending for any continuous
length surrounding the chimney.
Reference
Figures 15 and 16
and charts “Framing Dimensions for Ceiling and Roof,” which
specify minimum ceiling and roof dimensions.
For new construction, to determine chimney center line, use plumb line from ceiling or roof above
fireplace to the center of fireplace flue collar.
For remodeling, plumb to the center of the
fireplace flue collar from the ceiling or roof
above. Drive a nail through the ceiling or roof
from below to mark position. Mark and cut a hole
in the ceiling (around the nail) (
Figure 20
). Then
plumb from ceiling or roof directly above the cut
hole to determine roof hole position.
For Canadian Installations, Proceed
with Steps 6 through 9
Step 6. Attach the cold climate kit, Model
FTF10-CCK1-LD, around the chimney collar
with the screws provided (

Figure 19
INSTALLING THE CHIMNEY SYSTEM
Step 1. Check the flue damper for proper op-
eration. When the flue damper is in the fully
).
closed position, the damper control lever is
pushed all the way to the rear of the firebox.
When the damper is in the fully open position,
the flue damper control lever is pulled all the
way to the front of the firebox.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Figure 20
Note: The optional collar duct kit, Model FTF10-
CDK, should be installed after the chimney has
been attached to the flue collar.
Step 3. Position the appropriate firestop
spacer at the ceiling and nail temporarily with
two (2) 8d nails. Use a flat firestop spacer,
Model F10FS-2, for the FTF10 system if chimney penetrates vertically. If the chimney penetrates through the ceiling at a 30° angle (offset
chimney) then use a 30° firestop spacer, Model
F10FS30-2. Use one nail on opposite sides of
the firestop to hold in position. Nail permanently, using at least two (2) more 8d nails,
after the chimney sections have been assembled
through the firestop spacer and after necessary
adjustments have been made. The firestop
spacer must be secured in place by at least four
(4) 8d nails when completely installed.
Note: If there is a room above the ceiling level,
the firestop spacer must be installed on the
bottom side of the ceiling. If an attic is above the
ceiling level, the firestop spacer must be installed on the top side of the ceiling joists
(Figures 21 and 22 ).

January 1, 1992. The appropriate model designations are located in the back of this manual.
The FTF10 chimney system is a two piece chimney that snap locks together from the fireplace
up. Always start with the inner flue section. With
the lanced end up, snap lock the joint into the
matching collar on top of the fireplace. At all
subsequent joints, the upper flue section fits into
the lower or preceding flue section. Each section
snaps together by means of locking tabs (9 tabs
per joint). Check each section by pulling up
slightly from the top to ensure proper engagement before installing succeeding sections. If
the flue has been installed correctly, it will not
separate when tested. Also, the inner flue joint
where each section is joined should be tight and
flat without gaps (
Figure 26
).

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.

Step 4.
Note: All chimney sections are con-
structed with a unique locking tabs and hem
design, which ensures and immediate, tight
assembly between sections. Plan your chimney
requirements carefully before assembly, as the
chimney is difficult to disassemble after installation. If disassembled, the tabs might become
damaged. Be certain that the tabs are properly
formed to ensure they engage properly.

Note: Assemble one component of chimney at a
time (inner section first; then outer section last)
before preceding 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 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 30
). Again, check the vertical
position of the chimney and the 2" minimum air
space to combustibles.
Step 8. The standard Security 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 32
). Check
all joints very carefully to ensure no water
intrusion can take place.
Locking Band
Waterproof
Caulk
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 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 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 29
).

Note: Do not caulk or seal the ventilating openings.
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
).
Figure 32
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 33 ). Guy wires are
not supplied by the manufacturer.

Note: It is recommended that all exterior ex-
posed 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.
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 (
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.

3. Center the outer locking section over outer
flue pipe. Push down until all locking tabs are
firmly engaged and locked.
4. Pull up slightly on CTDTM to ensure the
locking joint is firmly engaged and locked.
Using a FTF10-CT1 Chase Termination:
Refer to specific installation instructions included with FTF10-CT1 chase terminations for
clearance and installation details.
Using a FTF10-CT2 Chase Termination:
Refer to specific installation instructions included with FTF10-CT2 chase terminations for
clearance and installation details.
Less Than 10'
3'
Min
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 (

FTF10 CHIMNEY COMPONENT
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.
Figure 35
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

3. The effective heights of the components are:
The Fireplace = 48-3/8"
FTF10-12 = 10-1/4"
FTF10-18 = 16-1/4"
FTF10-36 = 34-1/4"
FTF10-CTDTM Termination = 13"
FTF10-CT1 Termination = 12" to 18"
FTF10-CT2 Termination = 15" to 23"
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'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 (
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
).
Figure
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
see
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 on page 13.
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 41
for reference.
14
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
Combustion Air Kits
Forced Air Kit
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 42
Figure 42
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.

You may use the combustion air kit, Model
FOAK-4 or FOAK-4LD, with the LBR/LBC Series
fireplaces. Refer to the installation instructions
packed with the air kit for specific installation
information. The outside air kit must be installed before the fireplace is totally framed and
enclosed within the finished walls.
The combustion air kit provides for outside air
to be drawn into the fireplace as an aid for
combustion. If installed, only one combustion
air kit is needed and it will be installed on the left
side of the fireplace. If additional length of air
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 air duct closer than 3'
(914 mm) below the chimney top.
There is a hand operated shut-off lever located in
the left side of the fireplace opening behind the
screen. To open, pull all the way. The combustion air damper should be fully open when the
fireplace is in use and completely closed when
the fireplace is not being used. This will prevent
outside cold air from entering the dwelling.
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.
CAUTION: NEVER LOCATE THE AIR INLET
WHERE IT COULD BE BLOCKED BY SHRUBS,
SNOWDRIFTS, ETC. NEVER LOCATE AIR INLET
IN A GARAGE OR IN 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 THAT THE
COMBUSTION AIR DUCT BE INSULATED.
The outside air ducting may be installed upwards
through framing and ceiling joists, with the inlet
hood installed through an outside wall. Air ducting may also be installed downward through
floor joists and under the dwelling to a ventilated
crawlspace not considered part of the living area.
Note: Do Not terminate the combustion air kit
in an attic space under any circumstances.
If you are installing the Lennox Forced Air Kit,
Model LFAK-2000, see the instruction sheet
provided with the kit for electrical wiring requirements. The fireplace has been pre-wired
at the factory but must be connected to main
power supply at the time of installation if the
LFAK-2000 is to be installed later. The electrical
connections must be made before the fireplace
is framed and enclosed in the finished walls.
CAUTION: ELECTRICAL CONNECTIONS
SHOULD ONLY BE PERFORMED BY A QUALIFIED, LICENSED ELECTRICIAN. MAIN POWER
MUST BE OFF WHEN CONNECTING FANS TO
MAIN ELECTRICAL POWER SUPPLY OR PERFORMING SERVICE.
Variable Speed Wall Switch
Refer to the installation instructions provided
with the Variable Speed Wall Switch, Model
VSWS, for installation details.
OPTIONAL EQUIPMENT
CONSIDERATIONS
Gas Line Connection
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.
15
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
Figures 43 and 44
.
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.
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.
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.
The installation of the CCK1 is recommended.
Refer to Steps 6 thru 9 on Page 8.
FIREPLACE FINISHES
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.
Mantels and Trim
These fireplaces may sit directly on a combustible surface. A 2" air space is required between
combustible framing and the chimney. In
Canada, the minimum height for a combustible
mantel is 18" (457 mm) above the fireplace
opening.
installations. For installations other than Canada,
combustible mantels and trim may either project
in front or be flush with the finished wall as per
NFPA 211 section 7-2.3.3. and
Figure 43
shows typical Canadian
Figure 44
.
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, or block the air
circulating opening of the fireplace

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 12" beyond both sides of the fireplace
opening and 20" beyond the front (
45 )
. Use a hearth extension constructed of a
durable noncombustible material having an
equal or better (lower k value) insulating value
of k = .84 BTU IN/FT2 HR °F or a thermal
resistance 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

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.

** 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.

(38mm)
Max. Thickness of Hearth Extension when
LBC Models are on the Floor
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
(refer to
Figures 6 & 7)
.
A wall shield is required where a continuous
perpendicular side wall is within 12" of the
fireplace opening (
Figure 46 )
. Use a 36" W x
36" H wall shield constructed of a durable,
noncombustible material having an equal or
better (lower k value) insulating value than k =
.54 BTU IN/FT2 HR °F. At no time may a
perpendicular side wall be located closer than
9" from the fireplace opening.
If fireplace is installed diagonally across a 90°
corner; no wall shields are required.
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 cov-
ers 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

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
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.
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 7-3/4" (197MM)

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