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-

require flashing spacers. Slide flashing all the
way down until the flashing base rests flat on
the roof (

position of the chimney and the 2" minimum air
space to combustibles (
see **Note ).

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
roofcaulking.Covernailheadswithroofcaulk-

Slide the storm collar over outer chimney, rest
on flashing spacers and align with top surface
offlashing. Insert tab in slot, pull tightand 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 com-
pletelyagainst water penetration ( seeFigure 28
). Check all joints very carefully to ensure no
water intrusion can take place.

Note: It is recommended that all exterior
exposed metal fireplace components; such
asterminations,flashings, storm collars and/
or flue be painted with a premium quality,
high temperature, rust preventative paint
designed for metal. This is especially impor-
tant when installations are made in abnor-
mally adverse or corrosive environments;
such as near lakes, oceans or in areas with
consistently high humidity conditions. Con-
sult 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 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 ).
