Hayward H300 Conversion from Propane to NG

[Corban987]

Hi
I have the option of buying a Hayward H300 at half price (2-3 years old, never used), however it is Propane and I need NG, does anyone know the conversion process and the approximate cost.
Thanks in advance....

At minimum there is an orifice change that is required. Most likely though the gas valve needs to be updated as well. I would hazard a guess of $200-$300

The Hayward part # on the conversion kit if the heater is Electronic Ignition (digital display) is HAXCNK0010 and if it is a Milivolt (manual control knobs) then the part # is HAXCNK0002. The kit includes the gas valve and orifices and run about $250 online.
