Somewhere on the forum I read where one switched a water heater burner(n/g), over to propane, what does one need to do to switch over and where is the best place to get the parts? I just had to replace my w/heater, burner is in very good condition so maybe a little salvage is in store.

You need a smaller orifice. Try a pumbing supply house
SWANEEDB,
In one of my smelters I used a commercial water heater burner that was originally propane, converted to natural gas and then I converted it back to propane.
The manager at the local propane supplier helped me with sizing the orifice and getting pressures right for the BTU's I was looking for.

Look up your local Propane dealers, the ones who deliver propane. They will give you all needed info.

Propane uses a smaller orifice than the same BTU Natural Gas burner but also uses Higher Pressure than NG. Most Natural Gas Controls have a built in Pressure Regulator which often is not convertible to propane. I have never seen a NG Residential Water Heater that was convertible to Propane. If it's just the burner from a water heater then there is an orifice conversion chart from NG to Propane.

I have had a N.G. water heater converted to propane. The service man for the propane co. did it for me for a reasonable amount.
