I have a Summers Heat 55-SHPAH and I'd like to slow the auger feed down if possible. I've already used the bottom button and arrows to program it to "1" but I'd like to slow it down even more. My current settings using the bottom 3 buttons are 1-5-1. It burns very clean and hot and I think I could slow it down even more w/o the flame burning out from fuel starvation. Any ideas?
