INTRODUCTION
General Information
CLEARANCES AND HEIGHT
REQUIREMENTS
Note: These fireplace systems are not difficult
to install. However, in the interest of safety, it is
recommendedthattheinstallerbeaqualifiedor
certified “tradesman” familiar with commonly
accepted fireplace installation and safety tech-
niques as well as prevailing local codes.
These fireplaces are conventional radiant heat
fireplaces with standard bar grates, optional
outside combustion air kits and optional deco-
rative glass doors.
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
and fireplace outer wrapper require a minimum
2" air space to combustibles. A combustible
mantle may be installed 12" above the opening
of the fireplace as per NFPA 211, Section 7-
2.3.3.
Note: Illustrations shown reflect “typical”
installations with nominal dimensions and
are for design and framing reference only.
Actual installations may vary due to indi-
vidual design preferences. However, always
maintain minimum clearances to combus-
tible materials and do not violate any specific
installation requirements.
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.
The minimum installed height of the completed
fireplacesystemis15'0". Themaximumheight
is 60' 0".

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.
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.
TYPICAL INSTALLATION
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.
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 and 17 ).
CHIMNEY SYSTEM
These fireplaces are designed and code listed
for use with Security Chimneys FTF10 chimney
System only. Always use Security Chimneys
FTF10 chimney components with these fire-
places. Do not modify or alter these compo-
nents as this may cause a potential serious
hazard and void the Warranty.

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-

Step4.Note:Chimneysectionsareconstructed
with a unique locking tab design, which en-
sures an immediate, tight assembly between
sections.Planyourchimneyrequirementscare-
fully before assembly as chimney is difficult to
disassembleafterinstallation. Ifdisassembled,
the tabs might become damaged. Be certain
tabsareproperlyformedtoensurelockingtabs
engage properly.
Note: Assemble one component of chimney at
a time (inner section first, then outer section
last) before proceeding with the next complete
section.
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.
Continue to assemble the chimney up through
framed opening. Assemble just enough to pen-
etrate the roof flashing openings (Figure 25 ).
Always maintain 2" minimum air space to com-
bustiblematerialsandalwayscheckeachchim-
ney joint (inner and outer) to ensure proper
engagement. Checkverticalalignmentofchim-
ney so that it projects from the roof in true

Step 6. Select the proper Security Chimneys
roof flashing based on pitch of roof. Use chart
below for selection:
Security Chimneys FTF10 chimney system is a
two piece chimney, which snap together from
thefireplaceup. Startwiththeinnerfluesection
with the lanced end up, snap lock it in to the
matching collar on top of the fireplace. At all
subsequent joints, the upper flue section fits
into the preceding flue section. Each piece
snaps together by means of locking tabs (9
locking tabs per joint). Check each piece by
pullingupslightlyfromthetoptoensureproper
engagement before installing the next section.
If the flue has been installed correctly, it will not
separate when you test it. Also, the inner flue
joint where each section is joined should be
tight and flat without gaps (Figure 23 ).

Outer pipe section installs in just the opposite
way; the lanced end goes down and each new
section goes OVER the outside of the previous
section installed (Figure 24 ).
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 caulk-
ing (Figure 28 ).
Install the Model FTF10-S4 stabilizer by fitting
inner section down into respective section of
proceeding flue pipe and locking outer stabi-
lizer section into place over the outer chimney
pipe. Position for proper clearance through

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 26 ).

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.
Figure 31
3. Center outer locking section over outer flue
pipe. Push down until locking tabs are firmly
engaged.
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.
4.PullupslightlyonCTDtoensurelockingjoint
has firmly engaged.
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.
Figure 29
Using a FTF10-CTDT Chase Termination:
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 29 ).
Refer to specific installation instructions in-
cluded with the FTF10-CTDT chase termination
for clearance and installation details.

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 32 ).
Refer to specific installation instructions in-
cluded with FTF10-CT1 chase terminations for
clearance and installation details.
Using a FTF10-CT2 Chase Termination:
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 30 ). Guy wires are not
supplied by the manufacturer.

3. The effective heights of the components are:
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 37 ). Be sure to drill only through the
outer chimney casting. Do not puncture the
inner flue.
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 33 ).

Maximum offset of chimney system is 30°.
Two offsets must not be assembled to form a

SPECIAL OFFSET INSTRUCTIONS
Figure 33
To clear any overhead obstructions, you may
offset your chimney system using Security
Chimneys 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.
FTF10 CHIMNEY COMPONENT
CALCULATIONS
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 21 and 22 and
stabilizers as shown in Figure 26.
The minimum installed height of the com-
pleted fireplace system is 15' 0". The maxi-
mum height is 60' 0".
To determine the number of chimney sections
and chimney components required, follow
these steps:
A1
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 34 ).
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'
(Figure35). Example:IfC1 =10'thenC2 cannot
exceed 10'.

INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 38 for reference.
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.
87
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.ProceedbyusingtheStraightUpInstal-
lation Instructions for cutting and framing ceil-
ing and roof openings.

Note: SeeFramingandDimensionChartforthe
sizes of the ceiling and roof openings. The size
of the roof opening varies with the degree of
pitch of the roof.
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.
Step 2. Install the air inlet eyebrow (FOAK-
4 or FOAK-4LD) through the wall opening
(Figure 40 ). Push a 4 inch diameter NON-
COMBUSTIBLE Class 0 or Class I flexible
duct onto the eyebrow.
Offset Elbow Assembly
Step 3. With the two remaining sheet metal
screws and the two clamp brackets supplied,
secure the duct to the air gate assembly as
shown in Figure 41.
Combustion Air Kits
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.
The installation of an outside combustion air
kit is highly recommended. It is very impor-
tant to ensure good fireplace operation in
homes which are tightly weather sealed or
have ventilating appliances installed.
Step 1. Determine the source for outside air,
which can be installed through an outside wall
or into a ventilated crawl space. In either case,
a 4 1/2" diameter hole will be required for
installation of the air inlet assembly.
Return Elbow Assembly
Return elbows install the same way as round
terminations and stabilizers:
CAUTION: AVOID INSTALLING THE AIR IN-
LET WHERE THE OPENING COULD BE
BLOCKED BY SNOW, BUSHES OR OTHER
OBSTACLES. THE MAXIMUM HEIGHT FOR
THE OUTSIDE AIR IS 50 FEET ABOVE THE
HEARTH, PROVING THE AIR INLET IS TERMI-
NATED A MINIMUM OF THREE (3) FEET BE-
LOW THE CHIMNEY CAP LEVEL.
Step 1. Hold return elbow over top of last
chimney section.
Step 2. Center inner slip section into inner flue
pipe-slip down.
Figure 41
Step 3. Center outer-locking section over outer
chimneypipe.Pushdownuntillockingjointhas
firmly engaged.
OPTIONAL EQUIPMENT
CONSIDERATIONS
Note: Combustion air inlet ducts must not
terminate in attic space.
Step 4. Pull up slightly on return elbow to
ensure locking joint has firmly engaged.
Gas Line Connection
AIR INLET
EYEBROW
ASSEMBLY
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.
Step 5. Secure support straps to framing
members by nailing under tension in sheer
(Figure 39 ).
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.

tinuous length adjacent to the chimney.
Vent Free Appliances
Glass Doors
These units have been tested and approved to
ANSI/IAS/AGA Z21.11.2 for use with unvented
gas appliances and complies with the stan-
dard for Factory-Built fireplaces, UL 127.
If glass doors are to be installed on these
fireplaces, refertospecificinstallationinstruc-
tionspackedwiththeglassdoors. Useonlythe
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.
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.
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 Figure 42.
CAUTION: CERTAIN GLASS DOORS OVER-
LAPTHEBLACKMETALFACINGOFTHEFIRE-
PLACE. IF THE FIREPLACE HAS BEEN FACED
WITH NONCOMBUSTIBLE MATERIALS,
THERE MIGHT NOT BE SUFFICIENT CLEAR-
ANCE TO INSTALL THE GLASS DOORS OF
YOUR CHOICE. ENSURE ADEQUATE CLEAR-
ANCE IS MAINTAINED AT ALL TIMES SO AS
NOT TO INTERFERE WITH THE INSTALLA-
TION AND OPERATION OF GLASS DOORS.
FIREPLACE FINISHES
Mantels and Trim
These fireplaces have been marked with a
maximum rating of 40,000 BTU to assure that
homeowners do not exceed the allowable lim-
its for all allowed installations of mantles.
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.
NEVER INSTALL AN UNVENTED GAS LOG
SET WITH A BTU GREATER THAN 40,000.
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.
CAUTION: WHEN USING THE DECORATIVE
GAS APPLIANCE, THE FIREPLACE DAMPER
MUST BE SET IN THE FULLY OPEN POSITION.
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
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.
These fireplaces may sit directly on a combus-
tible surface. A 2" air space is required be-
tween combustible framing and the chimney.
Combustible mantels and trim may be in-
stalled 12" above the fireplace opening as per
NFPA 211, Section 7-2.3.3. and Figure 42. 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.

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-
tory material is very thin in this area and is
easily removed. Once a small hole has been
made, continuetappinguntilyouhavereached

The entire knockout does not have to be re-
moved. Remove insulation in the gas line

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 (Figure 43 ).
Use a hearth extension constructed of a du-
rablenoncombustiblematerialhavinganequal
orgreaterinsulatingvalueofk=.27BTU/INFT2
HR °F or a thermal resistance that equals or
exceeds r = 3.70 HR °F FT2 IN/BTU. With these
values, determine the minimum thickness/
material required using the formula and the
Table on page 17.

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.
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 Fig-
ures 6 and 7 ).

If common brick is used so that the 3 ¹⁄₂"
dimension is the height, “R” for the common
brick becomes:
Figure 45
“R”M = r x TM = 0.20 x 3 ¹⁄₂" = .70
Secure the hearth extension to the floor to
prevent possible shifting.
Using ¹⁄₂" of mortar to set the brick, “R” for the
Outside Combustion Air Kits
mortar is calculated as follows:

“R”M = r x TM = 0.20 x ¹⁄₂" = .10
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.
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
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 non-
combustible caulking material only to seal the
black metal facing to the surround material on
the finished wall.
The sum of all “R values” is:
.70 + .10 +. 068 + .10 = .968

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 3.70. An
additional layer of insulating materials must
be used.
Combustible materials may project beyond the
sides of the fireplace opening as long as they
are kept within the shaded areas illustrated in
Figure 46.
WARNING: THE CRACK BETWEEN THE
FIREPLACE AND THE HEARTH EXTEN-
SION MUST BE SEALED WITH A NON-
