DESCRIPTION
Table 19. Parts List
Vent Pipe & Drain Hose Assembly
1. Connect the horizontal 13.25" x 2" PVC pipe (supplied
with the unit) to the inducer motor rubber coupler
and secure using 3" hose clamp provided. NOTE: A
horizontal pipe length up to 18" is approved if pit location
circumstances require it to be further from the unit and
pad. A new support bracket or adaptor piece will have
to be field created to ensure the vent assembly does
not rotate.
2. Clean & glue the 2" x ½" reducer bushing into the Tee.
3. Install the ½" hose connector to the reducer bushing.
4. Place the 2" PVC Tee onto the end of the horizontal
pipe. DO NOT CEMENT THE TEE ON AT THIS TIME.
Drop a plumb line from the bottom of the ½" drain fitting
to the ground to locate the starting point of the pit or
trench.
Vertical Drain Pit Method
IMPORTANT NOTE: The flue condensate of this unit
is slightly acidic and some local codes may require
a neutralizing treatment when disposing directly into
the ground. Check state or local code requirements
for application of this equipment and if necessary
substitute limestone rock, chat, or lime pellets to
the pit to neutralize the condensate instead of using
basic rock or chat.
