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.  
These fireplaces have been tested and  
listed by Omni-Test Laboratories (Report  
No. 116-F-52-2) to U.L. standard 127.  
These units are intended for installation  
in residential homes and other buildings  
of conventional construction including  
commercial, not in mobile homes.

1. The Fireplace  
2. The Chimney and Termination  
3. The Optional Glass Doors  
4. The Optional Combustion Air Kits  
5. Optional Cold Climate Kit (Mandatory in  
Canada).  
These fireplaces have been tested for instal-  
lation in Canada to ULC-S610. For installa-  
tions in Canada, the chimney clearance to  
combustibles must be 2 inches and the  
Cold Climate 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.

PRE-INSTALLATION NOTES  
Metal Safety Strip  
Platform  
Floor  
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.  
INSTALLING THE FIREPLACE  
Note: Hearth extensions must not interfere with  
circulating grillwork  
Step 1. Slide the fireplace into prepared fram-  
ing or position fireplace in its final position and  
frame later.

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

The safety strips should extend from front of  
thefireplaceatleast1-1/2"andshouldextendto  
be at least flush with the sides. In the event a  
wooden support is used to elevate the fireplace  
abovethefloor,a“Ztypesafetystripshouldbe  
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,  
beneath the fireplace as illustrated (Figures 6,  
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.

Step 4. Fireplace should be secured 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 ).  
Step 7. Route the Class 0 metallic air duct out  
thebackwallorsidewall,upthroughtheceiling  
or floor joists to an outside wall. The air duct’s  
inlet should be located above any anticipated  
snow level.  
Note: If the fireplace is installed against an  
inside wall, the Class 0 metallic air duct may be  
extendedintoaventilatedatticspaceatleast18"  
(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.  
8d Nail Or  
Equivalent  
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.  
Figure 19  
Step 3. Position appropriate firestop spacer at  
ceiling and fasten temporarily with two (2) 8d  
nails or equivalent. Use flat firestop spacer,  
Model F8FS-2, if chimney penetrates ceiling  
vertically. If chimney penetrates ceiling at 30°  
angle(offsetchimney),use30°firestopspacer,  
Model F8FS30-2. Use one nail on opposite  
sidestoholdfirestopspacerinposition. Fasten  
permanently, using at least two (2) more 8d  
nailsorequivalent,afterchimneysectionshave  
been assembled through the firestop spacer  
andafteranynecessaryadjustmentshavebeen  
made. Firestop spacer must be secured by at  
least four (4) 8d nails or equivalent when com-  
pletely installed.  
Figure 17  
Note: The nailing tabs and the area directly  
behind the nailing tabs are exempt from the  
clearances described on page 5. Maintain at  
least 1" 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  
ofthedamper, asdescribedonpage4, (referto  
Figure 3 ).  
For Canadian Installations Proceed  
with Steps 5 through 8  
Step 5. Attach the cold climate kit, Model  
CCK-HCRD, around the chimney collar with  
the screws provided (see Figure 18 ).

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.  
CHIMNEY 30° OFFSET THROUGH FLOOR  
OR CEILING  
Itmaybenecessarytoassemblethechimneyat  
30° when passing through the floor or ceiling  
area. Use the F8FS30-2 firestop spacer as  
shown in Figures 22 and 23. Support the  
chimney at floor or ceiling penetration with a  
FTF8 stabilizer if distance of chimney below  
ceiling is 10' or more. Maintain 2" 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 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

The Security 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.  
Ifthefluehasbeeninstalledcorrectly, itwillnot

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 26 ).  
Install the Model FTF8-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  
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 28 ).

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 8. Slide the FTF8 storm collar (ordered  
separately) over outer chimney, rest on flash-  
ing spacers and align with top surface of flash-  
ing. Insert tab in slot, pull tight and bend tab  
back over slot. Seal storm collar to outer chim-  
ney 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 31 ). Check  
all joints very carefully to ensure no water  
intrusion can take place.

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 ).

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  
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  
installationsaremadeinabnormallyadverseor  
corrosive environments; such as near lakes,  
oceans or in areas with consistently high hu-  
midity conditions. Consult the paint manufac-  
turers instructions 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 ).

TEN FOOT RULE SUMMARY  
18"  
The minimum chimney height above the roof  
and/or to adjacent walls and buildings is speci-  
fied by all major building codes.  
CTDT  
* Required for every 30' of vertical chimney  
and/or 10' of offset chimney.  
CTDT  
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. Determine amount of chimney height re-  
quired by subtracting total combined height of  
all pre-selected components (fireplace and  
chimneycomponentsfromtotaldesiredheight.)  
24"  
24"  
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.

minethenumberofchimneysections(quantity  
and length) required.  
This suggestion is provided in the interest of  
betteroperation. Iftheterminationsarelocated  
too close to each other, smoke may migrate  
from one flue into the other.  
SPECIAL OFFSET INSTRUCTIONS  
To clear any overhead obstructions, you may  
offset your chimney system using Security's  
30° offset and return elbows. Use two elbows -  
anoffsetelbowtoinitiatetheoffsetandareturn  
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.  
FTF8 CHIMNEY COMPONENT  
CALCULATIONS  
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  
(see Figure 34 ).  
The minimum installed height of the com-  
pleted fireplace system is 15' 0". The maxi-  
mum height is 60' 0".

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

POWER TO THE FIREPLACE  
The Optional Blower Kit  
Operates on 115 volt 60 Hz  
150 watts AC  
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.  
Note: Using a soapy water solution (50% dish  
soap, 50% water) is an effective leak test  
solution but it is not recommended, because  
the soap residue that is left on the pipes/  
fittingscanresultincorrosionovertime. Never  
use an open flame to check for leaks.

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-  
torymaterialisverythininthisareaandiseasily  
removed. Once a small hole has been made,  
continue tapping until you have reached suffi-  
cientdiameterforthegaslinetofitthrough.The  
entire knockout does not have to be removed.  
Remove insulation in the gas line channel.  
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.

Glass Doors  
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.  
Hearth Extensions and Wall Shields  
In Canada, the minimum height for a com-  
bustible mantel is 18" (457 mm) above the  
fireplace opening. Figure 45 shows typical  
Canadianinstallations. Forinstallationsother  
than Canada, combustible mantels and trim

ing as per NFPA 211, Section 7-2.3.3. and  
Figure 46. If a mantel is of a noncombustible  
material, it is exempt from these require-  
ments as long as it does not interfere with the  
installation or operation of glass doors.  
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 (see Figure  
47 ). Use a hearth extension constructed of a  
durable noncombustible material having an  
equal or better (lower kvalue) insulatingvalue  
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

COLD CLIMATE INSULATION  
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.  
Combustible  
Mantel  
If the fireplace is installed on a combustible  
floor, use the metal safety strips (provided)  
on the floor extending half under the fire-

Answer - The minimum required thickness of the Micore 160 is .875,  
therefore round up to 7/8” and use the nearest standard thickness  
available which is 1.  
Using the r formula:

** If the hearth extension material(s) that is intended to be used is NOT listed  
on Table 1, the material can still be used if the material(s) is noncombustible.  
However, the manufacturer of the material must provide either the listed k-  
value per inch or r-value per inch with listed thickness so that the minimum  
thickness required for the hearth can be calculated (per instructions on this  
Page and/or as specified in the NFI Certification manuals).
