severe personal injury, death, or substantial
property damage.
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).
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
