I have a Fisher Papa Bear - when I open the draft knobs in the morning after being shut all night, and load the stove, it often if not usually cavitates. Why is this and how can it be prevented? On the advice of one of the members here, I've adopted the habit of only cracking the knobs slightly until the stovepipe heats up. Then I open up all the way until the stove itself gets up to temperature. But the cavitation happens regardless.
Thanks!
Thanks!
