Installation & Operation Manual

3 Sidewall direct venting (continued)

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.

5.Seal exterior openings thoroughly with exterior caulk.

1.When terminating multiple SYNC boilers terminate each vent/air connection as described in this manual (FIG. 3-5A).

￿WARNING All vent pipes and air inlets must terminate at the same height to avoid

possibility of severe personal injury, death, or substantial property damage.

2.Place wall penetrations to obtain minimum clearance of 12 inches (305 mm) between vent pipe and adjacent air inlet elbow, as shown in FIG. 3-5A for U.S. installations. For Canadian installations, provide clearances required by CSA B149.1 Installation Code.

3.The air inlet of a SYNC is part of a direct vent connection. It is not classified as a forced air intake with regard to spacing from adjacent boiler vents.
