IMPORTANT: PLEASE READ AND
UNDERSTAND THESE RULES TO
FOLLOW FOR SAFETY.
1. Before starting your fireplace installation,
read these installation instructions carefully to
besure you understandthemcompletely and in
entirety. Failure to follow them could cause a
fireplacemalfunction resulting inseriousinjury
and/or property damage.
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 manufac-
turerforuse 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 un-
usual environmental factors or conditions be-
yond our control.
15. Never, under any circumstances, install a
fireplace, chimney component or any acces-
sories, that has visible or suspected physical
damage as a result of handling or transporta-
tion. These items should be inspected by your
distributor or qualified factory representative
to ensure safe condition. When in doubt, con-
sult 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
recommendedthattheinstaller beaqualifiedor
certified “tradesman” familiar with commonly
accepted fireplace installation and safety tech-
niques as well as prevailing local codes.
The most important areas of concern dealing
withthe installation of factory-built fireplacesare
clearances to combustible materials, proper as-
sembly of component parts, height of the chim-
ney system, the proper use of accessories sup-
plied by the manufacturer and the techniques
employed in using finishing materials applied to
the wall surrounding the fireplace, hearth exten-
sions 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 BCF Series are wood-burning fireplaces fea-
turing a self-contained heat-circulating system.
A standard bar grate is also included to properly
position the fire. Outside combustion air kits,
decorativeglass doors,forcedair kits andthefan
adapter kit are available as optional equipment.
The BRF Series are conventional radiant-heat
fireplaces with a standard bar grate, optional
outsidecombustionairkitsandoptionaldeco-
rative glass doors.
Note: Illustrations shown reflect “typical” in-
stallations with nominal dimensions and are
for design and framing reference only. Actual
installations may vary due to individual design
preferences. However, always maintain mini-
mum clearances to combustible materials and
do not violate any specific installation require-
ments.
The BRF and BCF Series Fireplaces have been
tested and listed by Underwriters Laborato-
ries, Inc. (File No. MH8988-1/91) to the U.L.
127 standard for U.S. installations. These
unitsare intended for installation in residential
homes and other buildings of conventional
constructionincludingcommercial,notinmo-
bile homes.
These fireplace systems are designed for in-
stallation 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
BOCABasic/National Codes, the Standard Me-
chanicalCodeandtheUniformBuilding Codes.

CLEARANCES AND HEIGHT
REQUIREMENTS
The fireplace may be placed on or near normal
construction materials*. The combustion air
kit, firestop spacer and roof flashing (not chase
flashings) may be placed directly on or against
normal construction materials.* The chimney
requires a minimum 2" air space to combus-
tibles( See**Note ). Acombustiblemantlemay
be installed 12" above the opening of the fire-
place as per NFPA 211, Section 7-2.3.3.
The fireplace and chimney system must be
enclosed when installed in or passing through
aliving area wherecombustiblesor people may
come in contact with it. This is important to
prevent possible personal injury or fire hazard.

Chase Enclosure
A chase is a vertical box-like structure con-
structedtosurround thefireplaceandchimney.
Refer to
Figure 2 for a typical chase configura-
tion. 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 cli-
mate 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.Checkalsoforanyconcealed damage.
Checktheoperationofthedamper.Thedamper
is controlled through the use of a control lever
located within the firebox opening at the top
center just behind the firebox lintel (
Figure 3 ).
The control lever snaps into place at the ex-
treme range of motion, up and back in the
closed position. Firm pressure is required to
lock the damper closed. When pulled forward
and down, the damper is open.

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.
Whenlocatingthefireplace,considerationmust
be given to combustibles and final finishing.
See
Figure 5 and confine the final location of
combustible finish materials to the "Safe Zone".
If there is a continuous perpendicular side wall
closer than 15" from the nearest side of any 38"
fireplace opening or 18" from any 43" model, it
mustbeprotectedwitha40"x40"x¹⁄₂"wallshield

system including chimney and surround ma-
terials such as brick, stone, etc., to be in-
stalled. 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.Notethefloorconstruction,i.e.2x6’s,2x8’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 addi-
tional support.
CAUTION: DO NOT BLOCK THE HEAT-CIRCU-
LATING AIR INLET AND OUTLET PORTS ON

bustiblefloor.Maintainthefloortohearthclear-
ance established by the fireplace lower front
face.
Step 2. Insert the provided metal safety strips,
beneaththe fireplace as illustrated ( Figures6, 7
and 8 ). The safety strips should overlap ¹⁄₂" for
continual coverage of the floor.
Note: Safety strips are not required when fire-
place rests on a noncombustible surface.
To Install
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 illus-
trated( Figures6and7 ).Thesafetystripsshould
overlap 1" for continual coverage of the floor.
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 nor-
mal sequence of installation. Each installation
is unique, however, and might require a differ-
ent sequence.
1. Position firebox prior to framing or into
prepared framing.
2. Install the chimney system.
3. Field wire main power supply to BCF models
for fan kit and install CF-ADK adapter kit. (Elec-
tricalconnections should only beperformed by
an experienced, licensed/certified tradesman.)
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/certi-
fied tradesman.)
6. Complete the installation, finish wall mate-
rial, surround and hearth extension to your
individual taste.
7. Assemble and attach optional glass door
assembly.
Study the three dimensional illustration ( Fig-
ure 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,vinylorothersoftfloorcoverings.It
may, however, be placed on flat wood, ply-
wood, 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:
Figure 7
Note: Install the hearth extension only as illus-
trated.
The safety strips should extend from front and
sides of the fireplace 2". 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
ofthe woodsupportaswell asthefloorbeneath
the hearth extension ( Figures 8 and 9 ). The
safety strips should be tacked down to prevent
possible movement.
Note: The “Z” type safety strip is not supplied
by Superior.
Step 3. Refer to fireplace drawings and speci-
fications on pages 6 and 7 for framing dimen-
sions and details. Framing header may be posi-
tioned directly on the fireplace top spacers.

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 (
Figure 18 ).
In new construction, to determine chimney
center line, use plumb line from roof or ceil-
ing 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 19 ). Then plumb from ceiling or
roof level directly above hole which has just
been completed.
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
least1/2" clearance from the firebox wrapper to
the framing at the closest point of contact,
directly adjacent to the flange.
INSTALLING THE CHIMNEY SYSTEM
Step 1. Before continuing, check the operation
of the damper, as described on page 4, ( refer to
Figure 3 ).
Step 2. Using standard construction framing
techniques,constructopeningforchimneyroute
upthroughtheceiling(s)androof orthroughan
outside chase.
Framing must maintain adequate minimum air
space clearance at all times.
CAUTION:ALLOW MINIMUM2"CHIMNEY AIR
SPACE TO COMBUSTIBLE FRAMING MEM-
BERS THROUGHOUT VERTICAL OR OFFSET
CHIMNEY INSTALLATION ( SEE **NOTE ).
A minimum 2" air space must be reserved for
all combustible materials extending for any
continuous length surrounding the chimney
( See **Note ).
**Note: 1" clearance when installing FTF8 on
38" models or FTF10 on 43" models.
Reference Figures 16 and 17 and charts Fram-
ing Dimensions for Ceiling and Roof, which
specify minimum ceiling and roof dimensions.
Figure 19
Note: If Desired the optional collar duct kit,
Model FTF8-CDK or FTF10-CDK, should be
installedafter the chimney hasbeenattachedto
the flue collar.
Step3. Position appropriate firestop spacer
at ceiling and nail temporarily with two (2)
8d nails. Use flat firestop spacer, Model
F8FS-2, or F8FS30-2, if chimney penetrates
ceiling vertically ( See *Note ). If chimney
penetrates ceiling at 30°angle (offset chim-
ney), use 30°firestop spacer, Model FS30,
F8FS30 or F10FS30 ( See *Note ). Use one
nailonopposite sides to hold firestop spacer
in position. Nail permanently, using at least
two (2) more 8d nails, after chimney sec-
tions have been assembled through the
firestop spacer and after any necessary ad-
justments have been made. Firestop spacer
must be secured by at least four (4) 8d nails
when completely installed.
*Note: Use Models F8FS-2 and F8FS30-2 to
maintain 2" clearance when installing FTF8
chimney on 43" fireplaces.

Step 4. Note: Chimney sections are con-
structed with a unique locking tab design,
which ensures an immediate, tight assembly
betweensections. Planyourchimney require-
ments carefully before assembly as chimney
is difficult to disassemble after installation. If
disassembled, the tabs might become dam-
aged. Be certain tabs are properly formed to
ensure locking tabs engage properly.
Security Chimneys FTF8 and FTF10 chimney
systems are two piece chimneys, 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
fluesection fits into the preceding fluesection.
Eachpiece snapstogetherby meansoflocking
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
(
see Figure 22 ).
Figure 21
Figure 20
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 20 and 21 ).

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. 9
Security's chimney sections do not need to be
screwed together. Additional reinforcement is
not necessary except in certain offset condi-
tions (refer to page 14,
Figure 36 ).
Step 5. The height of vertical chimney pipe
supported only by the fireplace must not ex-
ceed 30'. Chimney heights above 30' must be
supported by a Model FTF8-S4 stabilizer in-

TEN FOOT RULE SUMMARY
The minimum chimney height above the roof
and/or to adjacent walls and buildings is speci-
fied by all major building codes.
If the horizontal distance from the peak of the
roof is less then 10', the top of the chimney
must be at least 2' above the peak of the roof.
If the horizontal distance from the chimney
edge to the peak of the roof is more than 10' a
chimney height reference point is established
on the roof surface 10' horizontally from the
chimney edge. The top of the chimney must be
at least 2' above this reference point. In all
cases, the chimney cannot be less then 3'
above the roof at the edge of the chimney.
The 2' in 10' rule is necessary in the interest of
safety but does not ensure smoke-free opera-
tion. Trees, buildings, adjoining roof lines,
adverse wind conditions, etc., may require a
taller chimney should the fireplace not draft
properly ( Figure 31 ).
MULTIPLE TERMINATIONS
If more than one termination is located in the
same chase or within the same general prox-
imity, 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 termina-
tion of one smoke exit to the termination of
another smoke exit ( see Figure 32 ).

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.
CHIMNEY COMPONENT CALCULATIONS
The minimum installed height of the BRF-3875
and BCF-3885 Series Fireplace Systems is 12'.
The minimum installed height of the BRF-4375
and BCF-4385 Series Fireplace Systems is 15'.
The maximum height for all systems is 80'.
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
wouldincludefirestopspacers,stabilizers,roof
flashing, etc.
3. The effective heights of the components are:
The Fireplace = 38"
SS Starter Section = 19 ¹⁄₄"
FTF8/10-12 = 10 ¹⁄₄"
FTF8/10-18 = 16 ¹⁄₄"
FTF8/10-36 = 34 ¹⁄₄"
FTF8-48 = 46 ¹⁄₄"
FTF8/10-CTD Termination = 4"
FTF8/10-CT1 Termination = 12" to 18"
FTF8/10-CT2 Termination = 15" to 23"
FTF8/10-CTDT Termination = 12" to 18"
FTF8/10-S4 Stabilizer * = 3"
* Required for every 30' of vertical chimney
and/or 10' of offset chimney.
4. Determine amount of chimney height re-
quired by subtracting total combined height of
all pre-selected components (fireplace and
chimneycomponentsfromtotaldesiredheight.)
Reference Vertical Elevation Chart and deter-
minethe number of chimney sections (quantity
and length) required.
SPECIAL OFFSET INSTRUCTIONS

Figures 33 and 34 . Support the chimney at
floor or ceiling penetration with a FTF8 stabi-
lizer if distance of chimney below ceiling is 10'
or more. Maintain 2" minimum air space to
combustibles from chimney sections.
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.
When offsetting directly off the 43" systems,
always use a FTF10-30 offset elbow. A starter
section, Model BC8-SS or FTF8-SS, must then
be used as a transition to the BC8 or FTF8
chimney system.

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 ( see
Figure 35
). The stabilizer support straps must
be attached under tension (in shear) to struc-
tural framing members above. When two sets
of elbows are used, the maximum combined
length of chimney used between elbows can-
not exceed 20' ( see Figure 36 ). Example:If C1
= 10' then C2cannot 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 ( see Figure 37 ).
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 ( see
Figure 38 ). 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 sys-
tem exceeds 25'.
Return elbow support straps must be securely
attached under tension (in shear) to structural
framing members above. Do not substitute a
FTF8/10-30 offset elbow in place of a FTF8/10-
E30 return elbow.
OFFSET CALCULATIONS
Step 1. Use Offset Chart to determine amount
of horizontal offset (A) and height (B) for vari-
ous chimney section assemblies.
Step 2. Use “Height of Chimney Only” column
in The Vertical Elevation Chart to determine
combinations of chimney used above return
elbow to achieve desired heights. Reference
Components Effective Height Chart in vertical
elevation chart section.
Step 3. Use Elevation Chart as job estimator
only.Add necessary firestopspacersandstabi-
lizers as required. Firestop spacers must be
used as shown in Figures 21 and 22 and stabi-
lizers as shown in Figure 26 .

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. 15
Step 1. Determine the offset distance where
chimney is to pass through the first ceiling-
dimension “A.” To find this point on your ceil-
ing, first determine the center point for a verti-
cal chimney following the instructions for ver-
tical 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
showthecenterpointforyouroffsetceilingcut.
Step2.Proceed byusingtheStraightUpInstal-
lation Instructions for cutting and framing ceil-
ing and roof openings.
Note:See Framing and Dimension Chart forthe
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 connec-
tion 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. Centerouter-locking section over outer
chimneypipe.Pushdownuntillockingjointhas
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 40 ).
Note: The return elbow assembly performs the
same function as a stabilizer. Consider this
when determining the need for a stabilizer.

If you are installing a forced air kit, Model
FAK-1500, on BCF models; see the installa-
tion instructions provided with the kit for
electrical wiring requirements. Use a fan
adapter kit, Model CF-ADK, to allow the fire-
place to be connected to the main power
supply. The fireplace must be connected to
main power supply at time of installation if a
forced air kit 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 QUALI-
FIED,LICENSEDELECTRICIAN.MAINPOWER
MUST BE OFF WHEN CONNECTING THE CF-
ADK ADAPTER 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.
Combustion Air Kits
Use combustion air kit, Model AK-4 or AK4-LD,
withthe BCF andBRFSeries fireplaces. Referto
installation instructions packed with the air kits
for specific installation information. The out-
sideair kit must be installed beforethefireplace
is framed and enclosed in the finished walls.

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 IN-
SIDE 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 refrac-
torymaterialis verythininthisareaandiseasily

Glass Doors
If glass doors are to be installed on these
fireplaces, refer to specific installation instruc-
tions packed with the glass doors. Use only the
doors that are listed for use with these fire-
places. 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 FIRE-
PLACE. IF THE FIREPLACE HAS BEEN FACED
WITHNONCOMBUSTIBLEMATERIALS,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.
Outside air drawn into the fireplace supplies air
to the fire for combustion. Only one combus-
tion air duct on the left side of the fireplace is
necessary if installed (
Figure 41 ).
Gas Line Connection
Install a ¹⁄₂" gas supply line through fireplace
wall for connection to a decorative gas appli-
anceinside 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 con-
nection with a match or open flame.
This provision is intended for connection to a
decorative gas appliance incorporating an au-
tomatic 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 re-
quirementsforGas-FiredLogLightersforWood
Burning Fireplaces, Draft No. 4 dated August,
1993. Install in accordance with the National
Fuel Gas Code, ANSI Z223.1. This complies
with the revised U.L. 127 standard.
Vent Free Appliances
These fireplaces have been tested and ap-
provedto ANSI/IAS/AGAZ21.11.2foruse with
unvented gas appliances and comply with the
standard for Factory-Built fireplaces, UL 127,
when installed with unvented gas log sets.
Special instructions with regards to mantle
installations must be taken into consideration
when installing such appliances.
These fireplaces have been tested for use
with any unvented log set having a maximum
rating of 26,000 BTU (38 Models) and 32,000
BTU (43 Models). The minimum mantle con-
figuration for these log sets are outlined in
Figure 42 .
Log sets with 40,000 BTU may be installed
provided that no combustible mantle projec-
tions are placed lower than 18 inches from the
fireplace opening.
These fireplaces have been marked with a
maximum rating of 26,000 BTU (38 Models)
and 32,000 BTU (43 Models) to assure that
homeowners do not exceed the allowable lim-
itsfor allallowedinstallations of mantles. That
limit may be increased to 40,000 BTU, pro-
vided that the mantle installed complies with
the 18-inch limitation and a copy of these
instructions are available.

There is a one hand operated shut-off valve
located in the left side of the fireplace opening
behind the screen. To open, pull out all the way.
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.

COLD CLIMATE INSULATION
If you live in a cold climate, it is especially
important to seal all cracks around the fire-
place 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 noncombus-
tible caulking material only on fireplace facing
to seal. Also, the outside air inlet duct should
bewrappedwith noncombustible insulation to
minimize the formation of condensation. Do
not place insulation materials on top of fire-
place 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
(See **Note).
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 fire-
place or chimney system.
FIREPLACE FINISHES
Mantels and Trim
It is sometimes best to frame your fireplace
after it is positioned and the chimney is in-
stalled. Frame enclosure for chimney and fire-
place with 2 x 4’s (or heavier) lumber.
Note:Theheader may restonthetwo(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 combus-
tible surface. A 2" air space is required be-
tween combustible framing and the chimney
( See **Note ). Combustible mantels and trim
may be installed 12" above the fireplace open-
ing as per NFPA 211, Section 7-3.3.3. and
Figure 42 . If a mantel is of a non-combustible
material, it is exempt from these requirements
as long as it does not interfere with the instal-
lation or operation of glass doors or block the
inlets and outlets on the BCF Series fireplaces.
**Note: 1" clearance when installing FTF8 on
38" models or FTF10 on 43" models.

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 ( see Figure 43 ). Use a
hearth extension constructed of a durable
noncombustible material having an equal or
greater insulating value of k = .84BTU/In Hr
Ft2 °F or a thermal resistance that equals or
exceeds r = 1.19 In Ft2Hr °F /BTU. With
these values, determine the minimum thick-
ness/material required using the formula
and the Table on page 17.
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 and 7 ).
A wall shield is required where a continuous
perpendicular side wall is within 12" of the
fireplace opening, (
see Figure 44 ). Use a 24"
W x 30" H wall shield constructed of millboard
or a durable, noncombustible material having
an equal or greater insulating value than K =
.54BTU/IN FT2HR °F. At no time may a
perpendicular side wall be closer than 7".

40" x ¹⁄₂" wall shield constructed of millboard or
a durable non-combustible material with equal
or greater insulating value than:
K = .84BTU-IN./SQ.FT.-HR.-°F
In no case shall a continuous perpendicular side
wall be closer to the fireplace opening than 8".
If fireplace is installed diagonally across a 90°
corner no wall shields are required.

MethodsofDeterminingHearthExtension
and Wall Shield Equivalents
To determine the thickness required for any
material when either the k or r values are
known:
TM= Thickness of material in inches
kM= K value of desired material
rM= R value of desired material
TL= Minimum listed thickness
Example: Micore CV230 is to be used for the
hearthextension fireplace. How thick must this
material be?
Using the k formula:
Desired k value of desired Min.thickness
Required = material (per inch) x of Listed
Thickness k value of listed Material
material (per inch)
TM (inches) = kMx TL
0.84
TM (inches) = 0.43* x ⁵⁄₈"
0.84
Answer using k = 0.51 x ⁵⁄₈" = 0.32 = ³⁄₈"
³⁄₈" thickness Micore will be required.
Using the r formula:
Desired r value of listed Min.thickness
Required = material (per inch)x of Listed
Thickness r value of desired Material
material (per inch)
TM(inches) = 1.19 x TL
rM
TM(inches) = 1.19 x ⁵⁄₈"
2.33*
Answer using r = 0.51 x ⁵⁄₈" = 0.32 = ³⁄₈"
³⁄₈" thickness Micore will be required.
At times it is important to know what combina-
tion of materials are acceptable for use as
hearth extensions. The “R values” are used to
determine acceptable combinations of materi-
als because “R values” are additive where r and
k values are not.
“R value” = 1 = r x thickness of material used

*value taken from chart
Example: Given that the required “R value” for
a suitable hearth extension used must be equal
to or greater than:
“R” = r x TL = 1.19 x ⁵⁄₈" = 0.74.
If it is desired to elevate a marble hearth exten-
sion 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:
“R”M = r x TM= 0.20 x 3 ¹⁄₂" = 0.70
Using ¹⁄₂" of mortar to set the brick, “R” for the
mortar is calculated as follows:
“R”M = r x TM = 0.20 x ¹⁄₂" = 0.10
A ³⁄₄" marble slab set in ¹⁄₂" mortar covers the
brick, “R” for the marble and mortar becomes:
“R”M= r x TM= 0.09 x ³⁄₄" = .068
“R”M= r x TM= 0.20 x ¹⁄₂" = .10
The sum of all “R values” is:
.70 + .10 +. 068 + .10 = .968
Thiswould not be anacceptablecombinationof
material for the hearth extension since the total
calculated “R value” of the materials used does
not exceed the required “R value” of 1.19.

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.
Onlynoncombustible 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 opera-
tion 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 illus-
trated in Figures 47 and 48 .
