The Navien GXXX001322 prevents damage to your drain pipes and sewers by neutralizing heater condensation.

Suitable for most brands of condensing propane or natural gas heaters (not only Navien).

The condensation produced as a by-product of burning propane or natural gas is semi-acidic and can potentially harm condensate pumps, sewer systems, waste water drain pipes. Tankless water heaters, boilers, and furnaces which are at least 93% efficient produce 1.6 gallons of acidic condensation every 400,000 BTUs of fuel burned.

The Navien Condensate Neutralizer Cartridge Kit neutralizes the semi-acidic condensate of your high-efficiency gas or propane appliance by increasing its pH levels from of 3-4 to a more neutral level before being discharged to your drain.

County building codes often require a condensate neutralizer at the drain line of high efficiency gas or propane appliances. Check the pH level annually at the outlet. The neutralization media must be replaced when the pH level falls below the minimum level of your local water authority.

This item is for residential installations for one heater. The limestone media is refillable and should replaced annually.


  •  All corrosion-resistant materials
  •  Can be mounted horizontally or vertically
  •  1.6 gallon per hour (6.05 liter per hour) rating for single applications only. Check your heater manufacturer for the heater's condensate flow rate. A heater that uses 400,000 BTU/h running at 93% efficiency will produce approximately 1.6 gal/hr of condensate.
