I have a Low Profile Banjo Burner that I bought from Northern Brewer last year.
I recently switched my setup from a 7 gal SS pot to a keggle. The first two batches using the keggle I ended up going through a ton or propane (almost the whole tank!) and as the boil went on, it was like the flame would not increase anymore.
Early in the boil, I turned the valve up too much and it shut off the gas automatically. There must be a built in shut-off. Later in the boil, (45 mins in or so), I saw the boil was not the rolling boil I like to have so went to turn up the gas and the flame reacted very little. In fact, I could open it all the way and it made little difference -- not at ALL like the roaring jet it was when I started.
Is my hose busted? Do I need a new regulator? Can I step it down to preserve propane?
