Step 8. The standard Security Chimneys FTF10
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 com-
pletely against water penetration (
Figure 30 ).
Check all joints very carefully to ensure no
water intrusion can take place.

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 ).

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 chimney joint. Locking bands wrap around
pipe joints equally covering the joints of both
pipe sections.
Step 10. Using the FTF10-CTDTM Round
Termination:
1. Hold CTDTM 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 CTDTM 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 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.
For Canadian installations, all chimney installed
outside the building must be galvalume (outer
sections only), effective January 1, 1992. The
appropriate model designations (with a “C”
suffix) are located in the back of this manual.
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' (3 m), the top of the
chimney must be at least 2' (610 mm) above
the peak of the roof.
If the horizontal distance from the chimney
edge to the peak of the roof is more than 10'
(3 m), a chimney height reference point is
established on the roof surface 10' (3 m) hori-
zontally from the chimney edge. The top of the
chimney must be at least 2' (610 mm) above
this reference point. In all cases, the chimney
cannot be less than 3' (914 mm) 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, ad-
verse wind conditions, etc., may require a taller
chimney should the fireplace not draft properly
(
see Figure 35 ).

Use the nut provided and TIGHTEN snugly. Do
not overtighten as this might damage the chim-
ney section (
refer to Figure 30 ).
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.
