Lucent Technologies EST-48 Ten Foot Rule Summary, Using a FTF13-CT1Chase Termination

Step 8. The standard Security Chimneys F10 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 com- pletely against water penetration (Figure 30 ). Check all joints very carefully to ensure no water intrusion can take place.

Step10.UsingaFTF13-CTDRoundTermination:

1.Hold the FTF13-CTD over top of last chimney section (Figure 32 ).

2.Center inner slip section in inner flue pipe- slip down.

Note: It is recommended that all exterior ex- posed 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 hu- midity conditions. Consult the paint manufac- turers instructions for proper preparation and application.

Chimney

The minimum chimney height above the roof and/or to adjacent walls and buildings is speci- fied by all major building codes.

If the horizontal distance from the peak of the roof is less then 10', the top of the chimney must be at least 2' above the peak of the roof.

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 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 trian- gular pattern (Figure 31 ). 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

If the horizontal distance from the chimney edge to the peak of the roof is more than 10' a chimney height reference point is established on the roof surface 10' horizontally from the chimney edge. The top of the chimney must be at least 2' above this reference point. In all cases, the chimney cannot be less then 3' 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 opera- tion. Trees, buildings, adjoining roof lines, ad- verse wind conditions, etc., may require a taller chimney should the fireplace not draft properly (see Figure 33 ).
