About This Item
The Pentair NG to Propane Conversion Kit (460755) is the OEM replacement conversion kit for the MasterTemp and Max-E-Therm Model 300 pool heater — allowing a natural gas unit to be reconfigured for liquid propane fuel supply.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED — GAS CONVERSION
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. Improper fuel conversion can result in fire, explosion, or carbon monoxide hazard.
⚠️ IMPORTANT: KIT CONTENTS — NOT A SINGLE COMPONENT
This listing is a complete conversion kit (Item Nos. 3 and 4 per the Pentair exploded diagram), not an individual part. Confirm kit contents against your heater's service documentation before ordering.
This kit converts the Model 300 burner system from natural gas to liquid propane operation. It includes the components required to reconfigure the gas train for LP fuel — specifically Item Nos. 3 and 4 as referenced in the Pentair parts diagram for the MasterTemp / Max-E-Therm 300 series. This kit is not included with the heater at purchase and must be ordered separately when a fuel-type change is required.

Pro Tip
Before ordering, confirm your heater's current fuel configuration by checking the rating plate on the unit — it will identify the model as NG (natural gas) or LP (propane). This kit is designed specifically for the Model 300 output rating and is not interchangeable with conversion kits for other MasterTemp output models. Have a licensed gas technician verify the gas supply pressure and regulator compatibility for LP operation before the conversion is performed.
