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:
• 5½ inch hole (140 mm) hole for 4 inch (102 mm)
vent pipe
• 7½ inch hole (191 mm) hole for 6 inch (152 mm)
vent pipe
Drill 3/16" diameter holes for inserting the plastic anchors
into the wall.
Installation & Operation Manual
2. For Polypropylene Only: Install the vent and air intake
sidewall adapters from Table 3F on page 21 into the vent
plate. Slide the sidewall retaining bracket down the
sidewall adapters fl ush 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 20 to seal the
vent pipe.
3. 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 4-5A
and 4-5B). 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.
