This high efficiency water heater produces acidic condensate that must be properly drained per local codes. The
water heater does not have a built-in neutralizer to raise the pH level. A neutralizer is available from the water
heater manufacturer, if needed. Follow the instructions in this section in order to install the condensate drain line.
•
All preventative measures and safety practices must be adhered to when draining condensate. The manu-
facturer 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.
•
Discharge condensate (acidic water) in accordance with all local codes and common safety practices. In
the absence of applicable local codes and regulations, the manufacturer recommends that a condensate
neutralizer is installed and dispose the condensate into a drain. See picture on page 35.
•
Use corrosion resistant pipe, such as PVC, for the condensate drain line. Do not use metallic pipe.
•
The condensate drain does not require a trap.
•
A field-supplied bypass is required if a neutralizer is installed.
•
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, blocked, or kinked. Ensure
that it slopes downward to allow condensate to flow freely. All portions of the condensate drain (neutral-
izer and drain tube) must be at a lower elevation than the water heater to prevent condensate water from
building up inside the heat exchanger.
•
Do not connect the condensate drain line directly to a condensate pump.
The condensate drain system must be inspected regularly to make sure it drains properly and in accordance with
local codes or the part manufacturer's instructions.
•
Condensate cannot be effectively neutralized if the neutralizer elements inside the Neutralizer accessory
have been completely consumed. If this happens, condensate will remain acidic and can possibly cause
damage to items such as pipes, concrete, etc.
•
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. This can be tested using litmus pH test strips.
•
Please ensure that the cartridge is properly replaced before the neutralizer elements have been completely
consumed.
