Condensate Drain; Condensate Drain Connections - Takagi 540P Indoor Installation Manual And Owner's Manual

• 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.
NOTICE
Follow all code requirements
of the local authority on
condensate neutralizers and
whether or not they are required
for the installation.
• Discharge condensate (acidic water) in accordance with all local codes and
common safety practices.
NOTICE
• 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.
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.
