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.
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 18 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.
