My new Smoke Hollow 38 inch propane exhibited the temp regulation issues reported by others. My first smoke worked well, but I was on the edge of being too hot with the burner control cranked to low. I contacted Outdoor Leisure Products via a webform Monday morning. They responded within thirty minutes, and the very next morning a new regulator assembly arrived at my house. It took five minutes to swap it out. I have a nice range of flame now, with the "normal" amount of blue. I am looking forward to doing some more spareribs this weekend!
