FWIW, I had no problem getting mine to light properly.
I started using it as 23 jets, but it was too much for a 10 gallon batch. It would boil violently.
So I plugged all but 10 jets. Works great now, and it's almost too much for a 10 gallon batch. I might try plugging 2 more jets to see how it performs.
I find that there is a lack of adjustability. This burner works best when it's on full or off. As soon as I turn it partially on, I get yellow flames.
I think it's a great burner. It costs me about 25 cents to boil a 10 gallon batch as opposed to several dollars if I were to use propane.
