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.)
ͻ
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
ͻ
Discharge condensate (acidic water) in accordance with all local codes and com-
mon safety practices.
ͻ
Use corrosion resistant pipe, such as PVC, for the condensate drain line.
Do not use metal pipe.
ͻ
The condensate drain does not require a trap.
ͻ
Maintain a downward slope on the drain line(s), including installations in which
the drain is not directly below the water heater.
ͻ
A field-supplied bypass is required if a neutralizer is installed.
ͻ
Do not connect the condensate drain line directly to a condensate pump.
ͻ
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.
