About This Item
The Pentair Natural Gas to Propane Conversion Kit (461063) is the OEM conversion kit for the MasterTemp 125 high-performance pool and spa heater, enabling a permanent fuel-source change from natural gas to liquid propane (LP).
⚠️ IMPORTANT: PROFESSIONAL INSTALLATION REQUIRED — GAS CONVERSION
Gas appliance conversions involve high-pressure fuel systems and combustion components. This kit must be installed by a licensed pool professional or qualified HVAC technician. Do not attempt to convert gas appliance fuel type without proper certification. Improper installation creates a risk of fire, explosion, or carbon monoxide hazard.
⚠️ IMPORTANT: THIS LISTING IS A KIT — NOT A SINGLE COMPONENT
This listing includes the complete conversion kit (multiple components) required to convert one MasterTemp 125 heater from natural gas to propane. All components are packaged together as a single kit under part number 461063.
This kit contains the components necessary to reconfigure the MasterTemp 125 burner system for liquid propane operation. Natural gas and propane operate at different pressures and require different orifice sizing; using a heater on the wrong fuel type without conversion will result in improper combustion, reduced efficiency, and potential equipment damage. This kit provides the correct OEM components to complete the conversion to Pentair's specifications for the 125 MBH model.

Pro Tip
Before ordering, confirm your heater is currently configured for natural gas — this kit converts from NG to LP only; there is no reverse application. The heater's fuel type is listed on the rating label affixed to the unit. Once the conversion is complete, the heater must be re-commissioned and leak-tested by a licensed technician before returning to service. 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.
