Prepare wall penetrations

1.Use the factory supplied wall plate as a template to locate the vent and air intake holes and mounting holes.

Air pipe penetration:

a.Cut a hole for the air pipe. Size the air pipe hole as close as desired to the air pipe outside diameter.

Vent pipe penetration:

a. Cut a hole for the vent pipe. For either combustible

or noncombustible construction, size the vent pipe

hole with at least a 1/2 inch clearance around the

vent pipe outer diameter:

• 7½ inch hole for 6 inch vent pipe

• 8½ inch hole for 7 inch vent pipe
