I was just wondering if anyone else had any issues with soot while using an SP10. I have burned off the paint, played with the air mixture, and still cannot seem to get a blue flame regardless of valve setting. I am actually wondering if this is a defective burner, because I have not found that others have not really complained about this. 4 boils with this burner and for the record, this is A LOT of soot, not just a dusting. The bottom looks as if it was painted black.
Brew kettle is an 8 gallon stainless (not a turkey fryer). And the regulator is the 20psi version. Thanks everyone.
Side note: about to do first all grain batch: just made 10 gallon HD Rubbermaid MLT. This forum has been such an enormous help so thanks to everyone who posts on this site. It's a great group.
