Hi guys! I am trying to figure out a problem that I am having with my new Hellfire from Blichmann. It pretty much comes assembled and I have the NG orifice installed properly. The problem I am having is that the flame is really uncontrollable. I am looking to get the same controlled blue flame as from Propane, but the Natural Gas is just not doing it. The flame is mostly yellow, and it is charring up (black soot) the bottom and sides of my brew pot. I've played around with the valve, and if I set it to nearly closed, the yellow flame goes away, but then a small breeze blows out the blue flame. Opening it all the way up means I get 10-inch yellow flames wicking around the sides. Blichmann support has been swamped and hasn't replied back to my requests for product support. Has anyone run into this with their Blichmann Hellfire (floor standing version)?
