Note: Do not apply excessive pressure to any subsequent chimney sections following the stabilizer when installing. Ensure each subsequent chimney section is securely attached by testing as noted in Step 4.
Step 6. Select the proper Security Chimneys roof flashing based on pitch of roof. Use chart below for selection:
Roof Pitch | FTF8 | FTF10 |
|
|
|
Flat to 6/12 | ||
|
|
|
6/12 to 12/12 | ||
|

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. Again, check the vertical position of the chimney and the 2" (51 mm) minimum air space to combustibles (See **Note).
Next, slide roof flashing over extended chimney section that previously has been installed above the roof opening in Step 4. FTF8 flashings require flashing spacers. Slide flashing all the way down until the flashing base rests flat on the roof (Figure 28 ). Again, check the vertical position of the chimney and the 2" minimum air space to combustibles.

Step 8. The standard Security Chimneys roof flashing assemblies include a storm collar. Slide storm collar over outer chimney, 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 where storm collar meets flashing and to the tab/slot area to seal completely against water penetration (Figure 30 ). 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 31 ). Guy wires are not supplied by the manufacturer.

Step 10. Using a CTD Round Termination:
1.Hold the CTD 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 CTD to ensure locking joint has firmly engaged.

Note: Do not caulk or seal the ventilating open- ings.
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

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 caulking (Figure 29 ).

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 30 ).
