Having issues getting the flame right on my burner setup in Video and Multimedia Posted May 18 Of course a video on YouTube haha I wasn’t a massive fan of the burner plans to begin with but figured since they worked for him and the comments had other people who it worked for I’d give it a shot. I’m not understanding what you’re saying though. 19 minutes ago, Alan Longmire said: You're not getting nearly enough air. That kind of burner needs a large, like 2" to 3/4", bell reducer on that end, and none on the other, with no obstructions on the large end. When direct end injection was popular most designs used a 1/4" pipe across the big end of the reducer. Where did you find the plans for this? There are lots of better and cheaper venturi burner designs out there. And here, for that matter.
