Step 10. Using a CTD Termination:

1.

  Hold the CTD over top of last chimney section

 

(

Figure 14

)

.

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 

exposed 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 

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-

fied by all major building codes.

Step 8.

 The standard Security Chimneys FTF8 

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 circumfer-

ence of pipe. Also add extra roof caulking to 

the tab/slot area to seal completely against 

water penetration (

Figure 12

).

 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 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. Use the nut provided and TIGHTEN 

snugly. Do not overtighten as this might damage 

the chimney section (

refer to 

Figure 12

)

.

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 13

). Guy wires are not 

supplied by the manufacturer.

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 11

).

 Center inner slip section in inner flue pipe-

slip down.

Next, slide roof flashing over extended chimney 

section that previously has been installed above 

the roof opening in

 Step 4

.  Slide flashing all the 

way down until the flashing base rests flat on 

the roof

 (

Figure 10

).

 Again, check the vertical 

position of the chimney and the 1"** minimum 

air space to combustibles.

**Note: 2” clearance to combustibles required in Canada.
