About This Item
The Pentair LP to NG Conversion Kit (461062) is the OEM replacement conversion kit for the MasterTemp 125 and Max-E-Therm 125 pool and spa heaters, enabling a permanent fuel-source change from liquid propane (LP) to natural gas (NG).
⚠️ 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. Converting a gas heater between fuel types involves gas line connections and burner orifice changes that require certification and local permit compliance.
⚠️ IMPORTANT: THIS LISTING IS A KIT — NOT A SINGLE COMPONENT
This listing includes the complete LP to natural gas conversion kit for the Model 125. All components required for the fuel conversion are included in the kit as a single unit of measure.
This kit provides all OEM-specified components needed to convert a Model 125 heater from liquid propane operation to natural gas. LP and natural gas operate at different supply pressures and require different orifice sizing; using the incorrect fuel configuration will result in improper combustion, unsafe operation, or heater shutdown. This kit is not included with the heater at time of purchase — it must be ordered separately when a fuel-source change is required.

Pro Tip
Before ordering, confirm your heater's current fuel configuration by checking the rating plate on the heater cabinet — it will state "LP" or "NAT GAS" as the fuel type. This kit converts LP-configured Model 125 units to natural gas only; it does not perform the reverse conversion. If your heater is already configured for natural gas, this kit is not required. Have your licensed technician verify the incoming gas supply pressure at the service point before installation — natural gas supply pressure requirements differ from LP and must be confirmed against the heater's installation manual.
