Re:converting NG toLP
I recently converted a fryer that I bought used and was assured that it ran on LPG, It did not. I had to purchase the pilot orifice and 3 burner orifices, I also had to purchase a new safety/combo valve. It was not inexpensive. The valve was bad. If I didn't have to replace the valve it would have been roughly 90$ to convert. It does indeed depend on the brand, some valves can be converted with a spring change, some cannot.
