ETi-400 Condensate Neutralizer Kit

This cartridge kit neutralizes the acidic condensate produced during natural gas or propane operation on a Pentair ETi-400 high-efficiency heater before it drains, protecting plumbing and the environment from the low-pH byproduct of condensing combustion.

Compatibility

• Pentair ETi-400 High Efficiency Natural Gas Heater (400K BTU)
• Does not fit the Pentair 475971 Indoor Air Intake Kit, a separate accessory

Often paired with the Pentair 475971 Indoor Air Intake Kit on ETi heaters that don't already have a condensate neutralizer installed.
