C. Chase Top

A metal chase top is required to seal the top of the chase around the chimney pipe. The top should include a turn- down and drip edge to prevent water from seeping into the chase. Provide a 1/8 in. (3 mm) gap around the flue pipe and slope the top downward away from the penetration. See Figure 29.1.

•All seams must be caulked to prevent leaks.

•A chase installation must use a chase top. Chase tops are available from your Quadra-Fire dealer or may be field constructed.

•Attach the chase top to the top of the chase.

WARNING

Fire Risk

•Never install a single wall slip section or smoke-pipe in a chase structure.

The higher temperature of this single wall pipe may radiate sufficient heat to combus- tible chase materials to cause a fire.

D. Install the Termination Cap

Note: To protect against the effect of corrosion on those parts exposed to the weather, the termination cap can be painted with a rust-resistant paint.

WARNING

Fire Risk

•The minimum overlap of cap to pipe MUST be met or chimney may separate from cap.

Separation allows sparks, heat and embers to escape.

•Install the chimney sections up through the chase enclosure. When using a Round Termination Cap, the uppermost top section of pipe must extend 6 in. (152 mm) above the top of the flashing collar to allow installation of the storm collar and termination cap. See Figure 29.3.

Figure 29.3 Installing a TR344 Round Termination Cap

•For installations utilizing a Round Telescoping Termination Cap, the uppermost chimney section must be below the top of the chase top, but not more than 14-1/2 in. (368 mm) below the top of the chase top. Minimum overlap of chimney and termination cap must be 1-1/2 in. (38 mm). See Figure 30.1 on page 30.
