About This Item
OEM Combustion Blower Replacement Kit for Pentair ETi Series Heaters
The Pentair Combustion Blower Replacement Kit (476000) is the OEM replacement blower assembly for the ETi 250 and ETi 400 pool and spa heaters.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
The combustion blower supplies the forced air required for proper fuel combustion within the ETi heater's burner assembly. When the blower fails or degrades, the heater may fail to ignite, produce incomplete combustion, or shut down on a safety fault. Replacing the blower with the OEM kit restores correct airflow and combustion performance to manufacturer specification.

Pro Tip
Before ordering, confirm your heater's model number from the rating plate affixed to the unit — ETi 250 and ETi 400 are distinct models and share this blower kit. When the blower is replaced, have your technician verify that the combustion air inlet and exhaust flue are clear of obstructions before returning the heater to service. A restricted flue can cause the new blower to fail prematurely.
