step 8. The standard Security Chimneys FTF8
roof flashing assemblies include a
storm collar. Slide the storm collar over
outer chimney, rest on flashing spacers
and 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 to the
tab/slot area to seal completely against
water penetration (Figure 30). Check
all joints very carefully to ensure no
water intrusion can take place.

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: It is recommended that all exterior
exposed 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.

step 9. FTF 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 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 25).
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 31). Guy wires
are not supplied by the manufacturer.
