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 FireCraft roof flash-
ing based on pitch of roof. Use chart below for
selection:
Roof Pitch
Flat to 6/12
6/12 to 12/12
Next, slide roof flashing over extended chimney
section that previously has been installed above
the roof opening in Step 4. F8 flashings require
flashing spacers. Slide flashing all the way
down until the flashing base rests flat on the
roof ( Figure 27 ). Again, check the vertical
position of the chimney and the 2" minimum air
space to combustibles.

Note: Do not caulk or seal the ventilating
openings.
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
flashing to the roof with roof caulking. Cover
fastener heads with roof caulking ( Figure 28 ).

Step 8. The standard FireCraft Technologies'
FTF8 roof flashing assemblies include a storm
collar. Slide the storm collar over outer chim-
ney, 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
Model
extra roof caulking to the tab/slot area to seal
completely against water penetration ( Figure
F8F6
29 ). 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 chim-
ney extends more than 6' above the roof flash-
ing, 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 over-
tighten as this might damage the chimney
section ( refer to Figure 24 ).
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 30 ). Guy wires are not
supplied by the manufacturer.

Step 10. Using a CTD Termination:
1. Hold the CTD over top of last chimney
section ( Figure 31 ).
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: It is recommended that all exterior ex-
posed related metal fireplace components,
such as terminations, flashings, storm collars
and/or flue be painted with a premium-quality,
high-temperature, rust-preventative paint de-
signed 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 consis-
tently high humidity. Consult the paint manu-
factures instructions for proper preparation
and application.
