The three nipples are for varying hotter temperatures. The more nipples you open, the hotter it will burn. You use the valve to fine tune. I almost always run mine with 2 nipples closed and the valve about 3/4 open. This will give me about 250 degrees. If I want to run over 300 I have to remove another nipple cap.
