A. Chimney Termination

Chimney Termination Requirements (see Fig- ure 6.1)

•Must have a cap approved and listed for this fireplace system

•Must not be located where it will become plugged by snow or other material

•Must be located away from trees or other structures

WARNING

Fire Risk

•Must maintain 2 in. (51 mm) air clearance to insulation and other combustible materials.

C. 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 and refer to termination cap instructions.

NOTE: TR11/TR444 Round Termination Cap and TR11T/ TR442 Round Telescoping Termination Cap not recom- mended for Installations less than 20 feet.

B. 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.
