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 (Figure 23). Again, check the vertical
position of the chimney and the 1"** minimum
air space to combustibles.

step 7. Secure flashing by nailing along the
perimeter into roof using 8d nails or equivalent
fasteners. If shingled roof, slide upper end and
sides of roof flashing under shingles (trim if
necessary), seal the top and both sides of the

Seal storm collar to outer chimney with roof
caulking or mastic around entire circumfer-
ence of pipe. Also add extra roof caulking to
the tab/slot area to seal completely against
water penetration (Figure 25). Check all joints
very carefully to ensure no water intrusion can
take place.
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' 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 26). Guy wires are not
supplied by the manufacturer.

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.
