B. Install Fireplace & Chimney

Install as per Sections 7 and 8.

C. Install Chase Top Flashing

•You MUST use a chase top flashing in a chase installation. Chase top flashings are available from your Heat & Glo dealer or may be field constructed.

For chase enclosures, use a chase top flashing. The chase top flashing allows for a 1 1/2 in. (38 mm) clearance around the outside of the chimney pipe for ventilation air. Install the chase top flashing at the top of the chase with a 1/2 in. (13

mm)air clearance off the top of the chase constructions (Figure 9.4, 9.5). Use spacing clips to ensure the 1/2 in.

(13 mm) air clearance. If the chase top flashing does not fit the dimensions of the chase, a custom flashing can be field-fabricated as long as it has the same dimensions as noted in Figure 10.1. Secure the chase top flashing to the chase with at least three screws or nails per side. When installed, the bottom of the termination cap must be at least 6 in. (152 mm) above the chase top flashing (Figure 9.6).

•Install termination caps following instructions provided with them.

WARNING! Risk of Fire! The minimum overlap of cap to pipe (as shown in the following illustrations) MUST be met or chimney may separate from cap. Separation al- lows sparks, heat and embers to escape.

NOTICE: Paint the termination cap with a rust-resistant paint to protect against the effects of corrosion on those parts exposed to the weather.
