3Sidewall direct venting
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
•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 glue (cement/primer) listed in Table 2A on page 15 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.
4.Assemble the vent cap to the vent plate (see FIG.
5.Seal all wall cavities.

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
•5½ inch hole for 4 inch vent pipe
b.Insert a galvanized metal thimble in the vent pipe hole as shown in FIG.
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.

Termination and fittings
1.The air termination coupling must be oriented at least 12 inches above grade or snow line as shown in FIG.
2.Maintain the required dimensions of the finished termination piping as shown in FIG.
3.If using the alternate sidewall termination do not extend exposed vent pipe outside of the building more than what is shown in this document. Condensate could freeze and block vent pipe.
