The first question answer is yes. The valve was almost halfway open I'd say. As far as burping the air out I'm not sure. I just followed the directions to fill it. I believe it "burped out" some when it was full, and I read that was how you could tell it was full. Sorry I'm very new to torches. As far as the butane I'm using I just purchased it at Wal-Mart. "Ronson butane fuel"
This is the stuff I used,
I also have the Stach Rio and the included torch with that isn't like this at all. I can turn it way down without turning it off. It doesn't smell either.
