Multiple vent/air terminations
1. When terminating multiple boilers, terminate each vent/air connection as described in this manual (Figure 9-
14).
All vent pipes and air inlets must terminate at the same height to avoid possibility of severe
personal injury, death, or substantial property damage.
WARNING
2. Place wall penetrations to obtain minimum clearance of 12 inches (305 mm) between the inside edge of the
exhaust vent and the inside edge of the air intake elbow, as shown in Figure 9-14 for U.S. installations.
For Canadian installations, provide clearances required by CSA B149.1 Installation Code.
3. The air inlet of the 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.
Two pipe multiple boilers vent terminations.
