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:
• 3½ inch hole for 2 inch vent pipe
• 4½ inch hole for 3 inch vent pipe
Drill 3/16" diameter holes for inserting the plastic anchors
into the wall.
2. For Polypropylene Only: Install the vent and air intake
sidewall adapters from Table 3F on page 20 into the vent
plate. Slide the sidewall retaining bracket down the
sidewall adapters flush to the vent plate (FIG. 4-4B).
3. For PVC/CPVC Only: Install the vent and air intake
piping through the wall into the vent plate openings.
Use RTV silicone sealant to seal the air pipe. Use the
cement/primer listed in Table 3D on page 19 to seal the
vent pipe.
4. Mount and secure the vent plate to the wall, using stainless
steel screws.
5. Seal all gaps between the pipes and wall. Seal around the
plate to the wall assuring no air gaps.
6. Assemble the vent cap to the vent plate (see FIG.'s 4-4A
and 4-4B). Insert the stainless steel screws into the vent
cap screw hole openings and securely attach the vent cap
to the vent plate.
7. Seal all wall cavities.
8. PVC/CPVC terminations are designed to accommodate
any wall thickness of standard constructions per the
directions found in this manual.
9. Stainless steel terminations are designed to penetrate
walls with a thickness up to 9.25 inches of standard
construction.
