I'm burning the Englander 30 out of the basement and Have 4ft of stove pipe on the inside and 26ft of 6in. Stainless steal chimney on the outside. Today the weather was 40 degrees out. I loaded the stove with some ash and a couple of pieces of unidentified wood and once it got goin, I shut the air right off. The stove was runnin about 625-675 stove top,which is where I like it to run. But I was thinking that if It got too hot, there was no other way to shut it down since the air was already down al the way. So I am thinking I am gonna put a damper in the stove pipe, so if things get to hot. I will be able to shut it down completely, if needed. Any thought, one way or the other.
