I don't see why not but if they don't work just drill out the gas fitting jets to 3/32" maximum size would be 7/64" if 3/32" does not give enough flame'
If you use the furnace valves they only work on low pressure. So you have to drill the jet bigger and change to a low pressure regulator.
IMHO Low pressure sucks!:mad:

You will have to convert the burners to low pressure Propane but that's just drilling the jet.
I'm south of KC with 12" of the s**t and have to watch the kids my wife is staying at a Hotel near the Hospital so she can make it to work in the morning.
