Installation & Operation Manual

4 Vertical direct venting (continued)

Multiple vent/air terminations

1.When terminating multiple SYNC boilers, terminate each vent/air connection as described in this manual (FIG. 4-3).

￿WARNING Terminate all vent pipes at the same height and all air pipes at the same height to

avoid recirculation of flue products and the possibility of severe personal injury, death, or substantial property damage.

2.Place roof penetrations to obtain minimum clearance of 12 inches (305 mm) between edge of air intake elbow and adjacent vent pipe of another boiler for U.S. installations (see FIG. 4-3). For Canadian installations, provide clearances required by CSA B149.1 Installation Code.

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