OK, here is what I am finding out. The stove factory settings (3 bottom buttons) are set at 6-4-1. With milder temps at night 29-35 degrees. I adjusted mine to 5-3-1 and not as many pellets were sent to the burn pot and the flame is less intense, also have it set for 1 feed and 2 blower. Much more managable at keeping your house at 68-75 degrees. I would say if you keep your first two numbers (6-4-1) within 2 you can regulate the burn rate and keep your home more comfortable. I haven't noticed any difference in how dirty the glass is. Maybe when it gets colder will have to up the numbers again. Remember NEVER TOUCH THE LAST NUMBER! Let me know what you think.
