On-Demand Water Heater Installation Manual and Owner’s Guide
• 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.
• 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
• An accessory Neutralizer assembly (100112159/TH-NT01) is sold separately. (Refer to p. 11.)
• 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.

*Maintain downward slope, including installations in
which the drain is not directly below the heater.
**A 2" (50 mm) minimum distance must be main-
tained between the condensate line and drain to allow
full flow of the condensation.
•
The condensate drain is at atmospheric pressure (non-pressurized) and therefore must be allowed to drain freely with gravity only.
Ensure that the condensate drain tube is not plugged or blocked, and ensure that it slopes downward to allow condensate to flow
freely.
All portions of the condensate drain (neutralizer and drain tube) must be at a lower elevation than the water heater to prevent
condensate water from building up inside the heat exchanger.
•
Condensate cannot be effectively neutralized if the neutralizer elements have been completely consumed. If this happens, condensate
will remain acidic and can possibly cause damage to items such as pipes, concrete, etc., if drained improperly.
•
The actual life of the neutralizer may vary, depending on the application and usage. Replace the cartridge when the condensate pH goes
below 6.0.
•
Please ensure that the cartridge is properly replaced before the neutralizer elements have been completely consumed.
•
All preventative measures and safety practices must be adhered to when draining condensate. The manufacturer will not be responsible
for any damage caused by condensate.
•
A drain pan, or other means of protection against water damage, is recommended to be installed under the water heater in case of leaks.
