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 roof flash- ing 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 section that previously has been installed above
Step 8. Slide the FTF8 storm collar (ordered separately) over outer chimney, rest on flash- ing spacers and align with top surface of flash- ing. Insert tab in slot, pull tight and bend tab back over slot. Seal storm collar to outer chim- ney 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 31 ). Check all joints very carefully to ensure no water intrusion can take place.

Note: Do not caulk or seal the ventilating open- ings.
Step 7. Secure flashing by nailing along the perimeter into roof using 8d nails or equivalent. If shingled roof, slide upper end and sides of roof flashing under shingles (trim if neces- sary), seal the top and both sides of the flashing to the roof with roof caulking. Cover nail heads with roof caulking (Figure 30 ).

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