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:

• 4½ inch hole for 3 inch vent pipe

Drill 3/16" diameter holes for inserting the plastic anchors

into the wall.
