The other issue is whether the heater is designed to run on propane

or nat gas? If Ed's 10 PSI is correct, that's about 3x the pressure of

nat gas. Without modification, I don't think the heater is going to

be happy with the higher pressure.



Last I checked, propane was typically 11 inches water

column, natural gas is 3.5 inches. 10 PSI would be a

bit more then either of those.

Aye Carumba, you're right! Ed must have meant water column, not PSI and I
didn't catch it. So, the pressure units are as you say. But he's still
left with the issue that the pressures are different and frequently something
designed to be run on nat gas will require modification if it's going to
be run on propane. He needs to determine what fuel the heater is designed
to use. As you suggested, a good place to start would be finding the manual.
