Prepare wall penetrations (Alternate - Field Supplied Option)

1.	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.
2.	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

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

•5½ inch hole for 4 inch vent pipe

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

2.Install the vent and air intake piping through the wall into the vent plate openings. Seal all gaps between the pipes and wall. Use RTV silicone sealant to seal the air pipe. Use the cement/primer listed in Table 3A on page 17 to seal the vent pipe.

3.Mount and secure the vent plate to the wall using stainless steel screws. Seal around the plate to the wall assuring no air gaps.

	• 5½ inch hole for 4 inch vent pipe
	b. Insert a galvanized metal thimble in the vent pipe
	hole as shown in FIG. 4-4B.
3.	Use a sidewall termination plate as a template for correct
	location of hole centers.
4.	Follow all local codes for isolation of vent pipe when
	passing through floors or walls.
5.	Seal exterior openings thoroughly with exterior caulk.
