CLEARANCES AND HEIGHT
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 fireplace may be placed on or near normal
construction materials*. The combustion air kit,

prevent possible personal injury or fire hazard.
These fireplaces have been tested for installa-
tioninCanadatoULC-S610. Forinstallations
in Canada, the chimney clearance to com-
bustibles must be 2 inches and the Cold
Climat Kit must be installed.

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.

The fireplace may be installed directly on a
combustiblefloor or raisedonaplatformof 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.
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.

Step 4. Fireplace should be fastened to side
framing members using the nailing tabs at the
top and bottom of the fireplace front face. Use
8d nails or equivalent (Figure 17 ).
Note:Ifthefireplaceisinstalledagainstaninside

tended 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. Ensurethatnothingblocksthehood
opening. This air duct must never terminate
higher than the fireplace chimney.
Step 8. Cut or frame a hole through the outside
wall for the installation of the duct inlet hood. A
6-1/2" (165 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
collaroninlethoodusingtwo(2)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 air duct is needed,
use Class 0 metallic duct.

Step 3. Position appropriate firestop spacer at
ceiling and nail temporarily with two (2) 8d
nails. Use flat firestop spacer, Model F8FS-2, if
chimney penetrates ceiling vertically. If chim-
neypenetratesceilingat30°angle(offsetchim-
ney), use 30° firestop spacer, Model F8FS30.
Use one nail on opposite sides to hold firestop
spacer in position. Nail permanently, using at
least two (2) more 8d nails, after chimney
sections have been assembled through the
firestop spacer and after any necessary adjust-
ments have been made. Firestop spacer must
be secured by at least four (4) 8d nails when
completely installed.

Step 4. Note: Chimney sections are con-
structed with a unique locking tab design,
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.
Note: Assemble one component of chimney at
a time (inner section first, then outer section
last) before proceeding with the next complete
section.

OR CEILING
Itmaybenecessarytoassemblethechimneyat
30° when passing through the floor or ceiling
area. Use the F8FS30 firestop spacer as shown
in Figures 22 and 23. Support the chimney at
floor or ceiling penetration with a FTF8 stabi-
lizer if distance of chimney below ceiling is 10'
or more. Maintain 1"* minimum air space to
combustibles from chimney sections.
Continue to assemble the chimney up through
framed opening. Assemble just enough to pen-
etrate the roof flashing openings (Figure 27 ).
Always maintain 1"* minimum air space to
combustible materials and always check each
chimneyjoint(innerandouter)toensureproper
engagement.Checkverticalalignmentofchim-
ney so that it projects from the roof in true

The Security Chimney's FTF8 chimney system
is a two piece chimney, which snap together
from the fireplace up. Start with the inner flue
sectionwiththelancedendup,snaplockitinto

Step 8. Slide the FTF8 storm collar (ordered
separately) over outer chimney, rest on flash-
ing 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 com-
pletely against water penetration (Figure 31 ).
Check all joints very carefully to ensure no
water intrusion can take place.
Step10.UsingaFTF8-CTDRoundTermination:
1. Hold the FTF8-CTD over top of last chimney
section (Figure 33 ).
Step 6. Select the proper Security Chimneys
roof flashing based on pitch of roof. Use chart
below for selection:
2. Center inner slip section in inner flue pipe-
slip down.

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 thechimneyextendsmorethan
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 31 ).
Using a FTF8-CTDT Chase Termination:
Refer to specific installation instructions in-
cluded with the FTF8-CTDT chase termination
for clearance and installation details.
Figure 29
Using a FTF8-CT1 Chase Termination:
Note: Do not caulk or seal the ventilating
openings.
Refer to specific installation instructions in-
cluded with FTF8-CT1 chase terminations for
clearance and installation details.
Step 7. Secure flashing by nailing along the
perimeter into roof using 8d nails. If shingled
roof, slide upper end and sides of roof flash-
ing 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 30 ).
Note: If chimney extends more than 8' above
roofsurface, guywiresarealsorecommended.
Use three (3) guy wires, attach to locking band
assembly, extend and secure to roof in a trian-
gularpattern(seeFigure32).Guywiresarenot
supplied by the manufacturer.
Using a FTF8-CT2 Chase Termination:
Refer to specific installation instructions in-
cluded with FTF8-CT2 chase terminations for
clearance and installation details.
*Note: 2" clearance to combustibles required
in Canada.

To determine the number of chimney sections
and chimney components required, follow
these steps:
Less Than 10'

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.

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.
MULTIPLE TERMINATIONS
FTF8-18
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 35 ).

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 35
SPECIAL OFFSET INSTRUCTIONS
This suggestion is provided in the interest of
betteroperation. Iftheterminationsarelocated
too close to each other, smoke may migrate
from one flue into the other.
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.
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-
versewindconditions, etc., mayrequireataller
chimney should the fireplace not draft properly
(refer to Figure 34 ).

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 36 ).
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'
(Figure37).Example:IfC =10' thenC cannot

r and k values are not.
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 non-
combustible caulking material only to seal the
black metal facing to the surround material on
the finished wall.
