Step 10. Using a FBTM Termination:
1.
Hold the FBTM over top of last chimney
section (
Figure 30 ).
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 FBTM to ensure locking
joint has firmly engaged.
Note:
It is recommended that all exterior ex-
posed 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 hu-
midity conditions. Consult the paint manufac-
turers instructions for proper preparation and
application.
TEN FOOT RULE SUMMARY
The minimum chimney height above the roof
and/or to adjacent walls and buildings is speci-
fied by all major building codes.
If the horizontal distance from the peak of the
roof is less then 10', the top of the chimney
must be at least 2' above the peak of the roof.
If the horizontal distance from the chimney
edge to the peak of the roof is more than 10' a
chimney height reference point is established
on the roof surface 10' horizontally from the
chimney edge. The top of the chimney must be
at least 2' above this reference point. In all
cases, the chimney cannot be less then 3'
above the roof at the edge of the chimney.
The 2' in 10' rule is necessary in the interest of
safety but does not ensure smoke-free opera-
tion. Trees, buildings, adjoining roof lines,
adverse wind conditions, etc., may require a
taller chimney should the fireplace not draft
properly (
Figure 31 ).

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
extra roof caulking to the tab/slot area to seal
completely against water penetration (
Figure
28 ). Check all joints very carefully to ensure
no water intrusion can take place.

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
triangular pattern (Figure 29 ). Guy wires are
not supplied by the manufacturer.
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 cover-
ing 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 23 ).
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 27 ).
