I recently bought the Darkstar Burner and I’ve brewed 2 batches with it. I’m running into an issue though. I’m getting a bright orange flame rather than a hotter blue flame unless I have it set at anything other than full blast. As a result, during my boil, I’m creating a ton of black soot on the bottom of my kettle (and I’m using more propane than necessary, I think). I’ve tried adjusting what I think is the way to fix it without any luck. Am I missing something?
