Note: Do not apply excessive pressure to any subsequent chimney sections following the stabilizer when installing. Ensure each subse- quent 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 | Model |
|
|
Flat to 6/12 | F8F6 |
|
|
6/12 to 12/12 | F8F12 |
|

Next, slide roof flashing over extended chimney

Step 8. Slide the FTF8 storm collar (ordered separately) over outer chimney, rest on flash- ing 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 31 ). Check all joints very carefully to ensure no water intrusion can take place.

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 29 ). Again, check the vertical position of the chimney and the 1"* minimum air space to combustibles.

Note: Do not caulk or seal the ventilating openings.
Step 7. Secure flashing by nailing along the perimeter into roof using 8d nails. If shingled roof, slide upper end and sides of roof flash- ing 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 30 ).
*Note: 2" clearance to combustibles required in Canada.

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 31 ).
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 (see Figure 32 ). Guy wires are not supplied by the manufacturer.

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.
