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:
• 7½ inch hole for 6 inch vent pipe
• 8½ inch hole for 7 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 2A on page
16 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. 3-4A).
Insert the stainless steel screws into the vent cap screw
hole openings and securely attach the vent cap to the vent
plate.
5. Seal all wall cavities.
Prepare wall penetrations (Alternate Field
Supplied Options)
1. Air pipe penetration (see FIG. 3-4B):
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 (see FIG. 3-4B):
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:
• 7½ inch (178 mm) hole for 6 inch (152 mm) vent
pipe
• 8½ inch (203 mm) hole for 7 inch (178 mm) vent
pipe
b. Insert a galvanized metal thimble in the vent pipe
hole (when required by local codes).
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.
