From asking questions here on the forum, I have learned almost everything I know about my stove from you folks, that said, I am getting the feel of using the easy spin air controls on the doors of my stove, more open- more air, more heat. now the one thing I have no clue about, but hear mentioned alot from the old timers around here, is to damper down, not getting confused with closing the air inlets, do they mean closing the damper or on my stove called the damperslide, basically the stove flue, to retain heat slow burn etc, Is this safe to do? I know open her up to start fire,- I have been keeping it open all the way till the coals die out then shutting her up all the way to prevent cold air from chimney coming in. during burning, can this be partly closed, and if so is this done to prolong fire, retain heat? Trying not to sound too stupid here, but wanna learn all I can! Again this is not a 8 inch, 6 inch flue opening, but a damperslide that opens and closes the entire rear of stove, 3"X 30" thanks, and hope I'm not confusing the issue.
