About This Item
The Pentair Propane to Natural Gas Conversion Kit (77707-1431) is the OEM replacement conversion kit for the MasterTemp 200LP pool and spa heater, enabling a permanent fuel-source changeover from propane (LP) to natural gas (NG).
IMPORTANT: KIT INCLUDES MULTIPLE COMPONENTS
This listing is for the complete conversion kit (Key Nos. 3 and 4 per the MasterTemp 200 exploded diagram). Confirm both components are required before ordering — do not order individual parts separately if the full kit is needed.
IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
This kit involves modification of a gas-fired appliance. 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.
This kit provides all necessary OEM components to convert the MasterTemp 200LP from propane to natural gas operation. The conversion changes the fuel orifice and related components to match natural gas supply pressure and combustion requirements. Installing incorrect orifice components on a gas heater creates a serious safety hazard — use only the OEM kit matched to your specific heater model.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.
Poolaroo Pro Tip
Before ordering, confirm your MasterTemp is the LP (propane) model — the model number plate on the heater will show "200LP." The natural gas equivalent unit (200NG) does not require this kit. After conversion, a licensed technician must verify gas supply pressure, burner operation, and leak-test all connections before returning the heater to service. Keep the original LP orifice components in case documentation is needed for future service records.
