Sunday morning, finished my install on a Breckwell P23 insert, and I couldn't be happier as a rookie. The liner practically fell in, and I was worried about an offset that could've caused a problem. Turned the stove on with a full bag of Chow, and in less than 10 minutes we had a nice flame going with the damper set at "half". I have two seemingly dumb questions, but I’ll ask them anyway. 1) Do you folks typically leave your stoves unattended for many hours at a time, say 6-8 hours during the course of a day? I realize they’re running all night, but there’s someone on the premises, if God forbid there’s a problem. 2) I’m sure it varies considerably, but when you shut down for a good cleaning, how long typically for cool-down so it’s safe to get in there?
