Hi Bruce,
Glad you sorted it out. Can't remember if I had any problems. Anyway, if you want some measurements or other advice, I'm more than happy to help.
At the moment I'm trying out the propane demand valve from Howel. It works, but doesn't hold back much pressure from the gas bottle. Need an additional pressure regulator before the demand valve. Anyway, propane seems to be very forgiving to get going. Just a torch laying in front of the intake and leak some gas works fine (but of cause lets unburned gas into the room).
