Condensate disposal
Condensate drain
1. This water heater is a high efficiency appliance that
produces condensate.
2. The side of the water heater has a 1/2 inch PVC union
for connection of a 1/2 inch PVC pipe (FIG. 6-1).
3. Slope condensate tubing down and away from the water
heater into a drain or condensate neutralizing filter.
Condensate from the outdoor water heater will be
slightly acidic (typically with a pH from 3 to 5). Install
a neutralizing filter if required by local codes.
A Neutralizer Kit (FIG. 6-1) is available from the
factory.
4. Install the 1/2 inch PVC elbow (field supplied) as
shown in FIG. 6-1.
5. Do not expose condensate line to freezing temperatures.
Precautions should be taken to protect the condensate
management and disposal system during extended
periods of outdoor temperatures below 32°F.
6. Use only plastic tubing or piping as a condensate drain
line (FIG. 6-1).

7. A condensate removal pump is required if the water heater
is below the drain. When installing a condensate pump,
select one approved for use with condensing water heaters
and furnaces. The pump should have an overflow switch
to prevent property damage from condensate spillage. The
switch should be wired in series with the blocked drain
switch inside the water heater (see FIG. 7-1 on page 29).
Use materials approved by the authority
having jurisdiction. In the absence of other
authority, PVC and CPVC pipe must comply
with ASTM D1785 or D2845. Cement and
primer must comply with ASME D2564 or
F493.
To allow for proper drainage on large
horizontal runs, a second line vent may
be required and tubing size may need to
increase to 1 inch.

line
unobstructed, allowing free flow of
condensate.
If condensate is allowed to
freeze in the line or if the line is obstructed
in any other manner, condensate can exit
from the water heater tee, resulting in
potential water damage to property.
