Pentair NG to Propane Conversion Kit Model 175 | MasterTemp | 460794

Description

The Pentair NG to Propane Conversion Kit (460794) is the OEM replacement conversion kit for the MasterTemp 175 pool and spa heater, enabling a field conversion from natural gas to liquid propane fuel.

IMPORTANT: KIT CONTENTS — INCLUDES MULTIPLE COMPONENTS
This listing is for a complete conversion kit, not an individual part. The kit includes Item Nos. 3 and 4 from the MasterTemp 175 exploded parts diagram. Confirm the included components against your heater’s parts diagram before ordering.

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.

IMPORTANT: NOT INCLUDED WITH THE HEATER — ORDER SEPARATELY
This conversion kit is not supplied with the MasterTemp 175 heater at purchase. If you are converting your existing unit from natural gas to propane, this kit must be ordered and installed separately.

This kit provides the OEM components required to reconfigure the MasterTemp 175 heater’s gas train for liquid propane operation. Converting a natural gas heater without the correct OEM orifice and regulator components will result in improper combustion, reduced efficiency, and potential safety hazards — this kit supplies the manufacturer-specified parts to ensure the conversion is performed to Pentair’s design standards.

Specifications

Fits Into

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 175’s current fuel configuration by checking the rating plate on the heater cabinet — it will identify the unit as either NA (natural gas) or LP (propane). This kit is designed specifically for the 175,000 BTU MasterTemp model only; it is not interchangeable with conversion kits for the 200K, 300K, or 400K MasterTemp models. Always have a licensed gas technician or qualified pool professional perform the fuel conversion and verify gas pressure and leak-check the connections after installation.
