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.  
Vinyl siding is not recommended for use  
on the front of the fireplace due to the heat  
the unit produces. This can cause the vinyl  
siding to deteriorate.  
WARNING  
If insulation is used, the fireplace  
mustnotbeplaceddirectlyagainst  
it. Insulation or vapor barriers, if  
used, must first be covered with  
gypsum board, plywood, particle  
board or other material to assure  
insulation and vapor barriers  
remain in place.  
Note: Illustrations shown reflect “typical”  
installations with nominal dimensions and  
are for design and framing reference only.  
Actual installations may vary due to individual  
design preferences. However, always maintain  
minimum clearances to combustible materials  
and do not violate any specific installation  
requirements.  
INTRODUCTION

Refer to Figure 4 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  
chasebottom.Chaseinsulationinacoldclimate

(Required on All Indoor Instlaltions. When  
an Outside Air Kit is installed, see assembly  
steps on Page 6).  
Notes:  
Indoor Installations: 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  
29 & 30).  
*Note: 2"airspacetoinsulationandconstruc-  
tion materials required in Outdoor Installa-  
tions when system height is less than 15 feet  
(see Table 2, Page 4).  
Install the Air Gate Kit per the instructions  
provided with kit and on Page 6 (see Page 23  
for ordering information).  
In Canada, the chimney and outer wrapper  
require a minimum 2" air space to insulation  
and construction materials.  
Step 7. Outside Air Kit (provided)  
Outdoor Installations: If patio installation  
requires that a chimney passes through a roof  
or room above, be sure to comply with all local  
building codes.

Continue to assemble the chimney up through  
framed opening. Assemble just enough to  
penetrate the roof flashing openings (Figure  
36). Always maintain 1"* minimum air space to  
insulation and construction materials. Always  
check each chimney joint (inner and outer)  
to ensure proper engagement. Check vertical  
alignment of chimney so that it projects from  
the roof in true vertical position.  
The Security Chimney's FTF8 chimney system  
is a two piece chimney, 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 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 34).

Using a FTF8-CTDTM Chase Termination:  
Refer to specific installation instructions  
(750,205M) included with the FTF8-CTDTM  
chase termination for clearance and installa-  
tion details.  
Step9.SecurityChimneyslockingbands,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 chimney 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 damage the chimney  
section (refer to Figure 40).  
Figure 38  
Note: Do not caulk or seal the ventilating open-  
ings or seal the flashing at the chimney.  
Using a FTF8-CT1 or FTF8-CT1P Chase  
Termination:  
Refer to specific installation instructions  
(750,015M) included 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 39).  
Using a FTF8-CT2 Chase Termination:  
Refer to specific installation instructions  
(750,016M) included with FTF8-CT2 chase  
terminations for clearance and installation  
details.  
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  
triangular pattern (see Figure 41). Guy wires  
are not supplied by the manufacturer.  
* Notes  
• 2" clearance to insulation and construction  
materials required in Canada.  
Using a FTF8-CTT Chase Termination:  
Refer to specific installation instructions  
(750,077M) included with FTF8-CTT chase  
terminations for clearance and installation  
details.  
• Outdoor installations less than 15’ height  
require chimney clearance of 2” air space to  
insulation and construction materials.

Note: It is recommended that all exterior ex-  
posed metal fireplace components; such as  
terminations, flashings, storm collars and/or  
flue be painted with a premium quality, high  
temperature, rust preventative paint designed  
for metal. This is especially important when  
installations are made in abnormally adverse  
or corrosive environments; such as near lakes,  
oceans or in areas with consistently high  
humidity conditions. Consult the paint manu-  
facturers instructions for proper preparation  
and application.

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,thechimneycannotbelessthen3'above  
the roof at the edge of the chimney.  
4.Determineamountofchimneyheightrequired  
by subtracting total combined height of all pre-  
selected components (fireplace and chimney  
components from total desired height).  
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.

FTF8 CHIMNEY COMPONENT  
CALCULATIONS  
The 2' in 10' rule is necessary in the interest  
of safety but does not ensure smoke-free op-  
eration. Trees, buildings, adjoining roof lines,  
adverse wind conditions, etc., may require a  
taller chimney should the fireplace not draft  
properly (refer to Figure 43).  
SPECIAL OFFSET INSTRUCTIONS  
The minimum installed height of the completed  
fireplace system is 15' 0" for indoor installa-  
tions and 7' 9" for outdoor installations. The  
maximum height is 60' 0."  
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.  
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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  
exceed10'betweenelbows,achimneystabilizer  
must be used at the midpoint (Figure 45). 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  
chimney used between elbows cannot exceed  
20' (Figure 46). Example: If C1 = 10' then C2  
cannot exceed 10'.

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  
INSIDE THE FIREPLACE. DO NOT REMOVE  
THE KNOCKOUT UNLESS YOU ARE INSTALL-  
ING 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  
refractory material is very thin in this area  
and is easily removed. Once a small hole has  
been made, continue tapping until you have  
reached sufficient diameter for the gas line to  
fit through. The entire knockout does not have  
to be removed. Remove insulation in the gas  
line channel.

WARNING  
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.  
When installing hearth extension  
in front of a non-circulating fire-  
place model, the fireplace must be  
raised if height of hearth extension  
exceeds 7" above the bottom of  
fireplace (Figure 54).  
If common brick is used so that the 3 1/2”  
dimension is the height, “R” for the common  
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  
noncombustible caulking material only to seal  
the black metal facing to the surround material  
on the finished wall.
