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 chim-

ney 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 dam-

age the chimney 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.

Step 10. Using a FTF13-CTD Round Termination:

1. Hold the FTF13-CTD over top of last chimney

section (

Figure 32

2. Center inner slip section in inner flue pipe-

slip down.

Step 8. The standard Security Chimneys F10

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.

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.

Using a FTF13-CT1 Chase Termination:

Refer to specific installation instructions in-

cluded with FTF13-CT1 chase terminations for

clearance and installation details.

Using a FTF13-CT2 Chase Termination:

Refer to specific installation instructions in-

cluded with FTF13-CT2 chase terminations for

clearance and installation details.

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, ad-

verse wind conditions, etc., may require a taller

chimney should the fireplace not draft properly
