Step 10. Using an FTF8-CTD Round Termi-
nation:
1. Hold FTF8-CTD over top of last chimney
section (
Figure 40 ).
2. Center inner slip section in inner flue pipe-
slip down.
3. Center outer locking section over outer flue
pipe. Push down until locking tabs are firmly
engaged.
4. Pull up slightly on CTD to ensure locking
joint has firmly engaged.
Using a FTF8-CTDT Chase Termination:
Refer to specific installation instructions in-
cluded with the FTF8-CTDT chase termination
for clearance and installation details.
Using a FTF8-CT1 Chase Termination:
Refer to specific installation instructions in-
cluded with FTF8-CT1 chase terminations for
clearance and installation details.
Using a FTF8-CT2 Chase Termination:
Refer to specific installation instructions in-
cluded with FTF8-CT2 chase terminations for
clearance and installation details.
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-
lations are made in abnormally adverse or corro-
sive environments; such as near lakes, oceans or
in areas with consistently high humidity condi-
tions. Consult the paint manufacturers instruc-
tions for proper preparation and application.
Step 6. Select proper Security Chimneys roof
flashing based on pitch of roof. Use chart below
for selection:
Roof Pitch FTF8
Flat to 6/12 F8-F6
6/12 to 12/12 F8-F12
Next, slide roof flashing over extended chimney
section that previously has been installed above
the roof opening in Step 4. FTF8 flashings
require flashing spacers. Slide flashling all the
way down until the flashing base rests flat on
the roof (
Figure 36 ). Again, check the vertical
position of the chimney and the 2" (51 mm)
minimum air space to combustibles.
Note: Do not caulk or seal the ventilating
openings.
Figure 38
Step 9. Security Chimneys locking band,
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' (1.8 m) above the roof/flashing, the
use of locking bands is advisable to strengthen
the chimney joints. Align the locking band at
the pipe joint. Locking bands wrap around
pipe joints equally covering the joints of both
pipe sections. Use nut provided and TIGHTEN
snugly. Do not over tighten as this might
damage chimney section (
Figure 38 ).
Note: If chimney extends more than 8' (2.4 m)
above roof surface, guy wires are also recom-
mended. Use three (3) guy wires, attach to
locking band assembly, extend and secure to
roof in a triangular pattern (Figure 39 ). Guy
wires are not supplied by the manufacturer.

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 37 ).

Step 8. The standard Security Chimneys FTF8
roof flashing assembly includes a storm col-
lar. Slide storm collar over outer chimney,
align with top surface of flashing, insert storm
tab in slot, pull tight and bend tab back over
slot. Seal storm collar to outer chimney with
roof caulking or mastic around entire circum-
ference of pipe. Also add extra roof caulking
where storm collar meets flashing and to the
tab/slot area to seal completely against water
penetration (
Figure 38 ). Check all joints very
carefully to ensure no water intrusion can
take place.
