CONDENSATE DRAIN
The water heater does not include a built-in condensate neutralizer cartridge for reducing the pH level
of condensate water. If local codes dictate that condensate must be neutralized prior to drainage, a
condensate neutralizer must be installed. An accessory Neutralizer assembly (100112159/TH-NT01)
is sold separately. (Refer to p. 10.)
In the absence of applicable local codes and regulations, the manufacturer recommends that
condensate be disposed of into a drain. Connect a drain tube from the condensate drain port (shown
below) located on the bottom of the water heater to a standard drain.
Follow all code requirements
of the local authority for
condensate neutralizers and
whether or not they are required
for the installation.

NOTICE
Discharge condensate (acidic water) in accordance with all local codes and com-
mon safety practices.
Use corrosion resistant pipe, such as PVC, for the condensate drain line.
Do not use metal pipe.
The condensate drain does not require a trap.
Maintain a downward slope on the drain line(s), including installations in which
the drain is not directly below the water heater.
A field-supplied bypass is required if a neutralizer is installed.
Do not connect the condensate drain line directly to a condensate pump.
If the drain line is required to have bends, ensure that there are no kinks that
will restrict the flow of condensation.
NOTICE
The water heater is a high efficiency condensing water heater that produces condensate (acidic water).
The acidic condensate generated in the secondary heat exchanger can be neutralized by the neutralizer
accessory (100112159/TH-NT01).
Although a neutralizer is not required, a condensate drain must be installed as described on the next page.
