So i want to convert a jandy lg250n made in 2004 from natural gas to propane. I have read that you need the whole burner assembly but they list the orifice as a separate part. So do i need a whole assembly? Why ? Here is the list of what i think i need: Pilot burner
assembly p/n r0099200, gas valve p/n r0096900, orifice l0032900 (how many?). I cannot afford a new heater these pieces are around $500. Online. I got the heater with a used agp as a package deal. My other choice is to sell it and buy a used propane. Thanks in advance.
