Warranty & Compatibility

Compatibility Notes

This kit is for the MasterTemp 250 only. Other MasterTemp sizes (such as 200 and 400) use different conversion kits, and the natural-gas-to-propane direction uses a different part. Confirm your heater's model and current fuel type on the rating plate before ordering.

Installation Notes

Gas conversions must be done by a qualified, licensed gas technician following the Pentair MasterTemp installation manual and local codes. Shut off gas and power before work, check for gas leaks after the conversion, and confirm correct operation and gas pressure before returning the heater to service.
