About This Item
The Pentair Gas Orifice Kit – Propane (474980) is the OEM replacement propane gas orifice kit for the MasterTemp 125 Heater. This kit is not included with the heater at the time of manufacture and must be ordered separately when converting to or servicing propane gas operation.
⚠️ IMPORTANT: KIT LISTING — MULTIPLE COMPONENTS INCLUDED
This listing is a kit containing Items 3 and 4 from the MasterTemp 125 exploded parts diagram. It is not a single orifice. Confirm both components are required for your service before ordering.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas 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 propane gas orifice controls the fuel flow rate into the burner assembly of the MasterTemp 125 Heater. Using the correct orifice size for propane (LP) gas is critical — an incorrect orifice will cause improper combustion, reduced heating performance, or unsafe heater operation. This kit supplies the OEM-specified orifice components for propane service on the MasterTemp 125.

Pro Tip
This kit is propane (LP) specific — it is not interchangeable with the natural gas orifice kit. Before ordering, confirm your MasterTemp 125 is configured for propane service by checking the gas type label on the heater's rating plate. If you are performing a gas type conversion, consult the MasterTemp 125 installation manual and have the work completed by a licensed technician.
