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 flashing all the
way down until the flashing base rests flat on
the roof (
Figure 29
). Again, check the vertical
position of the chimney and the 2" minimum air
space to combustibles.

4. Pull up slightly on CTD to ensure locking joint
has firmly engaged.
Using a FTF8-CTDT Chase Termination:

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.
Using a FTF8-CTT 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 31
).
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 32 ). Guy wires are not
supplied by the manufacturer.

Step 10. Using a FTF8-CTD Round Termination:
1. Hold the FTF8-CTD over top of last chimney
section (
Figure 33
).
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.
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.
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 6. Select the proper Security roof flash-
ing based on pitch of roof. Use chart below for
selection:

Note: Do not caulk or seal the ventilating open-
ings.
Step 7. Secure flashing by nailing along the
perimeter into roof using 8d nails or equivalent.
If shingled roof, slide upper end and sides of
roof flashing under shingles (trim if neces-
sary), seal the top and both sides of the flashing
to the roof with roof caulking. Cover nail heads
with roof caulking (
Figure 30
).
