Installation & Operation Manual
Figure 4-4B Polypropylene 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 |

| 
 | 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  | 
| 
 | and  | 
| 
 | 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. |
