We are new to wood burning. I know all stoves are different. Our air control (draft control) goes from low, all the way in to high, all the way out. When we start fire we set it on high for about 15 minutes until it gets going good, then set it about halfway at 3. Lever reads from 1 to 6. We usually keep it at 3 during the day. At night we load the stove, get it going, then push air control all the way in for the slowest burn. Is it ok to have air control closed at night to get longer burn time? Its about 6 hours in between night and morning loading.
