Notes:
1. A horizontal vent must have a 45° or 90° vent termination elbow to direct the vent pipe downward unless
otherwise specified by local requirements.
2. A vertical vent must have a 90° elbow to direct the vent pipe horizontally followed by a vent termination 45°
elbow to direct the vent pipe downward unless otherwise specified by local requirements.
3. If additional elbows are used in the vent system the allowable vent lengths are reduced.
4. Two 45° elbows are considered the equivalent of one 90° elbow.
5. The pressure switch settings listed are only for installations at altitudes of up to, and includeing, 5,400'. For
operation at elevations above 5,400' but below 10,100', the heater requires a "Hi-Altitude Kit" (P/N 100308933).
