I keep running in to a issue. I burn only on weekends all day Friday-Sunday. At least once a weekend on a reload it goes nuts. It turns into a inferno and you can't turn it down. If you close the air it goes crazy on secondary burn and never seems to let up. The first few times I played with it until I got uncomfortable with the temps and the situation. If I pull a log out I can get it under control. I also noticed it smokes alot more on these reloads then any other. At first I thought it was a fluke but it's happened a few times know. What am I doing wrong. Thank you
