Step 10. Using a CTD Termination:
1. Hold the CTD over top of last chimney section
(Figure 27).
2. Center inner slip section in inner fl ue pipe-
slip down.
3. Center outer locking section over outer fl ue
pipe. Push down until locking tabs are fi rmly
engaged.
4. Pull up slightly on CTD to ensure locking
joint has fi rmly engaged.
Note: It is recommended that all exterior
exposed metal fi replace components; such as
terminations, fl ashings, storm collars and/or
fl ue 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.
TEN FOOT RULE SUMMARY
The minimum chimney height above the roof
and/or to adjacent walls and buildings is speci-
fi ed 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 op-
eration. Trees, buildings, adjoining roof lines,
adverse wind conditions, etc., may require a
taller chimney should the fi replace not draft
properly (Figure 28).
Step 8. The standard Security Chimneys FTF8
roof fl ashing assemblies include a
storm collar. Slide the storm collar over
outer chimney, rest on fl ashing spacers
and align with top surface of fl ashing.
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 25). 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 trian-
gular pattern (Figure 26). 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 fl ashing. As
a general rule, if the chimney extends
more than 6' above the roof fl ashing,
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).
Step 7. Secure fl ashing by nailing along the
perimeter into roof using 8d nails or
equivalent fasteners. If shingled roof,
slide upper end and sides of roof fl ash-
ing under shingles (trim if necessary),
seal the top and both sides of the
fl ashing to the roof with roof caulking.
Cover fastener heads with roof caulking
(Figure 24).
