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 31 ). Guy wires are not
supplied by the manufacturer.

Step 10. Using a CTD Round Termination:
1.
Hold the CTD over top of last chimney
section (
Figure 32 ).
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.
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 Chimneys
roof flashing based on pitch of roof. Use chart
below for selection:
Next, slide roof flashing over extended chimney
section that previously has been installed above
the roof opening in Step 4. Slide flashing all the
way down until the flashing base rests flat on
the roof. Again, check the vertical position of
the chimney and the 2" (51 mm) minimum air
space to combustibles (
See
**Note
).
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 28 ). Again, check the vertical
position of the chimney and the 2" minimum air
space to combustibles.
Figure 28
Note:
Do not caulk or seal the ventilating open-
ings.
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 29 ).
** Note:
1" (25 mm) when installed with FTF10
in the U.S. only.

Step 8.
The standard Security Chimneys roof
flashing assemblies include a storm collar. Slide
storm collar over outer chimney, 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 where storm collar meets
flashing and to the tab/slot area to seal com-
pletely against water penetration (
Figure 30 ).
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 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 30 ).
