Step 6. Select proper Security Chimneys roof flashing based on pitch of roof. Use chart below for selection:

Roof Pitch

FTF8

 

 

Flat to 6/12

F8-F6

6/12 to 12/12

F8-F12

 

 

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 flashling all the way down until the flashing base rests flat on the roof (Figure 36 ). Again, check the vertical position of the chimney and the 2" (51 mm) 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 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 37 ).

Step 8. The standard Security Chimneys FTF8 roof flashing assembly includes a storm col- lar. Slide storm collar over outer chimney, align with top surface of flashing, insert storm 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 38 ). Check all joints very carefully to ensure no water intrusion can take place.

Step 9. Security Chimneys locking band, 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' (1.8 m) above the roof/flashing, the use of locking bands is advisable to strengthen the chimney joints. Align the locking band at the pipe joint. Locking bands wrap around pipe joints equally covering the joints of both pipe sections. Use nut provided and TIGHTEN snugly. Do not over tighten as this might damage chimney section (Figure 38 ).

Note: If chimney extends more than 8' (2.4 m) above roof surface, guy wires are also recom- mended. Use three (3) guy wires, attach to locking band assembly, extend and secure to roof in a triangular pattern (Figure 39 ). Guy wires are not supplied by the manufacturer.

Step 10. Using an FTF8-CTD Round Termi- nation:

1.Hold FTF8-CTD over top of last chimney section (Figure 40 ).

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.

Using a FTF8-CTDT Chase Termination:

Refer to specific installation instructions included with the FTF8-CTDT chase termination for clearance and installation details.

Using a FTF8-CT1 Chase Termination:

Refer to specific installation instructions included with FTF8-CT1 chase terminations for clearance and installation details.

Using a FTF8-CT2 Chase Termination:

Refer to specific installation instructions included with FTF8-CT2 chase terminations for clearance and installation details.

Note: It is recommended that all exterior exposed metal fireplace components; such as ter- minations, flashings, storm collars and/or flue be painted with a premium quality, high tem- perature, 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 condi- tions. Consult the paint manufacturers instructions for proper preparation and application.
