Installation & Operation Manual

Figure 4-4BPolypropylene Sidewall Termination Assembly

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.

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:

•3½ inch hole for 2 inch vent pipe

•4½ inch hole for 3 inch vent pipe

b.Insert a galvanized metal thimble in the vent pipe hole as shown in FIG. 4-4C.

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.
