The most important areas of concern dealing
with the installation of factory-built fireplaces
areclearancestocombustiblematerials,proper
assembly of component parts, height of the
chimney system, the proper use of accesso-
ries supplied by the manufacturer and the
techniques employed in using finishing mate-
rials applied to the wall surrounding the fire-
place, hearthextensionsandwallshields. 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.
CLEARANCES AND HEIGHT
REQUIREMENTS
The fireplace may be placed on or near normal
construction materials*. The combustion air
kit,firestopspacerandroofflashing(notchase
flashings) may be placed directly on or against
normal construction materials.* The chimney
and fireplace outer wrapper require a mini-
mum 1"** air space to combustibles. A com-
bustible mantle may be installed 12" above the
opening of the fireplace as per NFPA 211,
Section 7-2.3.3 (1992). In Canada, the mini-
mum is 18" above the fireplace opening.
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.
INTRODUCTION
These fireplaces have been tested and listed by
WarnockHersey(ReportNo.J99025865B-231)
to U.L. standard 127. These units are intended
for installation in residential homes and other
buildings of conventional construction includ-
ing commercial, not in mobile homes.
General Information
The minimum installed height of the completed
fireplacesystemis15'0". Themaximumheight
is 60' 0".
These fireplaces are conventional radiant heat
fireplaces with standard bar grates, optional
outside combustion air kits and optional deco-
rative glass doors.
The fireplace and chimney system must be
enclosed when installed in or passing through
alivingareawherecombustiblesorpeoplemay
come in contact with it. This is important to
prevent possible personal injury or fire hazard.
These fireplaces have been tested for installa-
tion in Canada to ULC-S610. For installations
in Canada, the chimney clearance to com-
bustibles must be 2 inches and the Cold
Climat Kit must be installed.
TYPICAL INSTALLATION
For questions, please call your distributor or
the manufacturer. Special restrictions apply to
the front and facing of the fireplace and nearby
walls (See pages 16, 17 and 18 ).
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
BOCA Basic/National Codes, the Standard Me-
chanicalCodeandtheUniformBuildingCodes.

A chase is a vertical box-like structure con-

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.

PRE-INSTALLATION NOTES
Metal Safety Strip
Platform
Floor
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, 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.
Note: Hearth extensions must not interfere with
circulating grillwork
INSTALLING THE FIREPLACE
Step 1. Slide the fireplace into prepared fram-
ing or position fireplace in its final position and
frame later.
Figure 7
Note: Install the hearth extension only as illus-
trated.
The fireplace may not be recessed into a com-
bustiblefloor.Maintainthefloortohearthclear-
ance established by the fireplace lower front
face.
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
abovethefloor,a“Z”typesafetystripshouldbe
fabricated and used to protect the front surface
ofthewoodsupportaswellasthefloorbeneath
the hearth extension (Figures 8 and 9 ). The
safety strips should be tacked down to prevent
possible movement.
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.
Step 2. Insert the provided metal safety strips,
beneaththefireplaceasillustrated(Figures6, 7
and 8 ). The safety strips should overlap ¹⁄₂" for
continual coverage of the floor.
Usually, no special floor support is needed for
the fireplace, however, to be certain:
Note: Safety strips are not required when fire-
place rests on a noncombustible surface.
Note: The “Z” type safety strip is not supplied.

which ensures an immediate, tight assembly
between sections. Plan your chimney 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.
Continue to assemble the chimney up through
framed opening. Assemble just enough to pen-
etrate the roof flashing openings (Figure 28 ).
Always maintain 1"* minimum air space to

proceeding flue pipe and locking outer stabi-
lizer section into place over the outer chimney
pipe. Position for proper clearance through
framedopeningandnailstrapssecurely(under
tension in “shear”) into place on framing. Use
8d nails. Attach successive lengths of chimney
pipe directly to stabilizer using same tech-
niques as described in Step 4 (Figure 29 ).
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 chim-
ney 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 dam-
age the chimney section (refer to Figure 32 ).
Figure 30
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-
ing (Figure 31 ).
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 trian-
gular pattern (Figure 33 ). Guy wires are not
supplied by the manufacturer.

Roof Ridge
Note: Do not apply excessive pressure to any
subsequent chimney sections following the
stabilizer when installing. Ensure each subse-
quent 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:
Figure 31
120°
Step 8. The standard Security Chimneys FTF8
roof flashing assemblies include a storm col-
lar. 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.

FTF8 CHIMNEY COMPONENT
CALCULATIONS
Refer to specific installation instructions in-
cluded with the FTF8-CTDT chase termination
for clearance and installation details.
The minimum installed height of the com-
pleted fireplace system is 15' 0". The maxi-
mum height is 60' 0".
Using a FTF8-CT1 Chase Termination:
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, ad-
verse wind conditions, etc., may require a taller
chimney should the fireplace not draft properly
(see Figure 35 ).
Refer to specific installation instructions in-
cluded with FTF8-CT1 chase terminations for
clearance and installation details.
To determine the number of chimney sections
and chimney components required, follow
these steps:
Using a FTF8-CT2 Chase Termination:
1. Determine total vertical height of the fire-
place installation. This dimension is the dis-
tance from the surface the fireplace sets on
to the point where smoke exits from the
termination.
Refer to specific installation instructions in-
cluded with FTF8-CT2 chase terminations for
clearance and installation details.
MULTIPLE TERMINATIONS
If more than one termination is located in the
samechaseorwithinthesamegeneralproxim-
ity, we suggest they should be separated in
distance at least 24" horizontally from flue cen-
ter 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 (Figure 36 ).
Note: It is recommended that all exterior ex-
posed metal fireplace components; such as ter-
minations, flashings, storm collars and/or flue
be painted with a premium quality, high tem-
perature, rust preventative paint designed for
metal. This is especially important when instal-
lationsaremadeinabnormallyadverseorcorro-
siveenvironments;suchasnearlakes,oceansor
in areas with consistently high humidity condi-
tions. Consult the paint manufacturers instruc-
tions for proper preparation and application.
2. Determine the number of chimney compo-
nents required, except chimney sections. This
wouldincludefirestopspacers,stabilizers,roof
flashing, etc.

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.
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.
* 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.)
Step 2. Use “Height of Chimney Only” column
in The Vertical Elevation Chart to determine
combinations of chimney used above return
elbow to achieve desired heights. Reference
Components Effective Height Chart in vertical
elevation chart section.
Step 3. Use Elevation Chart as job estimator
only. Add necessary firestop spacers and sta-
bilizers as required. Firestop spacers must be
used as shown in Figures 23 and 24 and
stabilizers as shown in Figure 29.

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, an-
gling in any direction, may be the first compo-
nent 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 stabi-
lizer must be used at the midpoint (Figure 37 ).
The stabilizer support straps must be attached
under tension (in shear) to structural framing
members above. When two sets of elbows are
used, the maximum combined length of chim-
ney used between elbows cannot exceed 20'
(Figure38 ). Example:IfC1 =10'thenC2 cannot
exceed 10'.

tors to the right until the step in the actuator
moves behind the appliance front face within
the slotted opening.
The FBK-100/200 Blower Kits are design certi-
fied by Warnock Hersey for use with these
appliances.
These fireplaces have been marked with a
maximum rating of 32,000 BTU to assure that
homeowners do not exceed the allowable lim-
itsforallallowedinstallationsofmantles. 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.
Always check local building codes. Installation
of the FBK Blower Kits must comply with local
regulations as well as the National Electric
Code.
NEVER INSTALL AN UNVENTED GAS LOG
SET WITH A BTU GREATER THAN 32,000 IF
COMBUSTIBLE MANTLE PROJECTIONS ARE
LOWER THAN 18 INCHES ABOVE THE FIRE-
PLACE OPENING.
Combustion Air Kits
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.
These appliances are equipped with an outside
(make-up)airdoorandintegralactuatorarm. If
the appliance is to be installed with an outside
air vent system, use only FireCraft Models
FAOK or FAOK-LD Combustion Air Kits. These
kits come complete with detailed installation
instructions and all components necessary in
completing a combustion air vent system.
WARNING: MODELS THAT HAVE THE
"-2" SUFFIX HAVE NOT BEEN TESTED
WITH AN UNVENTED GAS LOG SET. TO
REDUCE RISK OF FIRE OR INJURY, DO
NOT INSTALL AN UNVENTED GAS LOG
SET INTO THIS FIREPLACE.
Gas Line Connection
Install a ¹⁄₂" gas supply line through fireplace
wall for connection to a decorative gas appli-
anceinsidethefirebox. Outside, thegassupply
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.
After completing the installation of the optional
combustion air vent system the actuator arm
must be put in service and tested to ensure
proper operation before completing any enclo-
sure around the firebox. Failure to do so may
result in extensive and costly rework.
CAUTION: WHEN USING THE DECORATIVE
GAS APPLIANCE, THE FIREPLACE DAMPER
MUST BE SET IN THE FULLY OPEN POSITION.
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.

1993. Install in accordance with the National
Fuel Gas Code, ANSI Z223.1. This complies
with the revised U.L. 127 standard.
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.
Locate the actuator arm along the right side of
the appliance firebox opening and refer to
Figure 45. After completing the installation of
the Outside Combustion Air Kit remove and
discard the actuator arm locking screw.

Glass Doors
These fireplaces may sit directly on a combus-
tible surface. A 2" air space is required be-
tween combustible framing and the chimney.
A 1" air space is required between combustible
framingandfireplaceouterwrapper. InCanada,
the minimum height for a combustible mantel
is 18" (457 mm) above the fireplace opening.
Figure 46 shows typical Canadian installa-
tions. For installations other than Canada,
combustible mantels and trim may be in-
stalled 12" above the fireplace opening as per
NFPA 211, Section 7-2.3.3. and Figure 47. If
a mantel is of a noncombustible material, it is
exempt from these requirements as long as it
does not interfere with the installation or op-
eration of glass doors.
Typical Installation
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.
Figure 47
Hearth Extensions and Wall Shields
A hearth extension must be installed with
all fireplaces. It is to protect the combustible
floor in front of the fireplace from both radiant
heat and sparks. The hearth extension must
extend 8" beyond both sides of the fireplace
opening and 16" beyond the front (Figure 48 ).
Use a hearth extension constructed of a du-
rablenoncombustiblematerialhavinganequal
orgreaterinsulatingvalueofk=.43BTUIN/FT2
HR °F or a thermal resistance that equals or
exceeds r = 2.33 HR °F FT2/BTU IN. With these
values, determine the minimum thickness/
material required using the formula and the
Table on page 17.
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

COLD CLIMATE INSULATION
Note: Any noncombustible material whose k
value is less than .43 or whose r value is more
than 2.33 is acceptable.
8" Max.
(203mm)
If you live in a cold climate, it is especially
importanttosealallcracksaroundthefireplace
opening with noncombustible material and
wherever cold air could enter the room. Sur-
rounding 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 fire-
place or against chimney sections.

This would not be an acceptable combination
of material for the hearth extension since the
total calculated “R value” of the materials used
is under the required “R value” of 2.33. An
additional layer of insulating materials must
be used.
