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 3.

Step 5. Select the proper Security Chimneys roof flashing based on pitch of roof. Use chart below for selection:

Roof Pitch

Model

 

 

Flat to 6/12

F10F6

 

 

6/12 to 12/12

F10F12

 

 

Next, slide roof flashing over extended chimney section that previously has been installed above the roof opening in Step 3. FTF10 flashings require flashing spacers. Slide flashing all the way down until the flashing base rests flat on the roof (Figure 26 ). Again, check the vertical position of the chimney and the 2" minimum air space to combustibles.

Figure 27

Step 7. The standard Security FTF10 roof flash- ing assemblies include a storm collar. Slide the storm collar 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 28 ). Check all joints very carefully to ensure no water intru- sion 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 29 ). Guy wires are not supplied by the manufacturer.

Note: Do not caulk or seal the flashing at the chimney.

Step 6. 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 27 ).

Figure 28

Step 8. 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 25 ).
