*Maintain downward slope, including installations in which the drain is not directly below the heater.
**A 2" (50 mm) minimum distance must be maintained 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 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., 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.
