1. Loosen the clamp on the inlet of the vent elbow attached to the
inducer.
2. Rotate the vent elbow to the required position. There are rounded
notches in the vent elbow to align it with the inducer housing for

Avoid short horizontal offsets with 90
deg. Elbows. Short offsets can be
difficult to slope and may trap con-
densate.
Use 45 deg. Elbows where
possible, to ensure conden-
sate drainage.
Slope vent pipe back to the
furnace at least ¼” per foot
