Multiple vent/air terminations

1.When terminating multiple Knight wall mount boilers terminate each vent/air connection as described in this manual (FIG. 4-5A).

￿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 between edge of air inlet and adjacent vent outlet, as shown in FIG. 4-5A for U.S. installations. For Canadian installations, provide clearances required by CSA B149.1 Installation Code.

3.The air inlet of a Knight wall mount 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.
