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 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 4. FTF10 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. Flashing Spacers FTF10 Flashing FTF10 Chimney Do Not Seal Figure 28 Note:Do not caulk or seal the ventilating openings. 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 necessary), seal the top and both sides of the flashing to the roof with roof caulking. Cover nail heads with roof caulking (Figure 29). Figure 29 Step 8. The standard Security Chimneys FTF10 roof flashing assemblies include a storm collar. Slide the storm collar over outer chimney, rest on flashing 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 completely against water penetration (Figure 30). Check all joints very carefully to ensure no water intrusion can take place. Locking Band WaterproofCaulk 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 chimney 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 damage the chimney section (refer to Figure 30). 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. Roof Ridge 120° Figure 31 Step 10. Using the FTF10-CTDTM Round Termination: 1. Hold CTDTM 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 CTDTM to ensure locking joint has firmly engaged. 20" (508mm) Figure 32 Using a CT2 Chase Termination Refer to specific installation instruction included with the CT2 chase termination for clearance statements and installation details.

Termination Air Space toCombustibles Above Roof Studs Figure 33 Note:It is recommended that all exterior exposed related metal fireplace components; such as terminations, flashings, storm collars and/ or flue be painted with a premium-quality, high- temperature, 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 conditions. Consult the paint manufacturers instructions for proper preparation and application. For Canadian installations, all chimney installed outside the building must be galvalume (outer sections only), effective January 1, 1992. The appropriate model designations (with a “C” suffix) are located in the back of this manual. TEN-FOOT RULE SUMMARY The minimum chimney height above the roof and/or to adjacent walls and buildings is specified by all major building codes. If the horizontal distance from the peak of the roof is less then 10' (3 m), the top of the chimney must be at least 2' (610 mm) above the peak of the roof. If the horizontal distance from the chimney edge to the peak of the roof is more than 10' (3 m), a chimney height reference point is established on the roof surface 10' (3 m) horizontally from the chimney edge. The top of the chimney must be at least 2' (610 mm) above this reference point. In all cases, the chimney cannot be less than 3' (914 mm) above the roof at the edge of the chimney. The 2' in 10' rule is necessary in the interest of safety, but does not ensure smoke-free operation. Trees, buildings, adjoining roof lines, adverse wind conditions, etc., may require a taller chimney should the fireplace not draft properly (see Figure 35).
