Still figuring out me new BK wood stove, and I've noticed that when I try to dial down the t-stat, i can smell a char smell coming from the top of the stove, around where the active/inactive thermometer sits. has anybody ever had this issue? Pretty much the only way i can avoid this smell is on a wide-open max T-stat setting, which doesn't really bode well for me getting long burn times or using the stove as it's intended. I've only been burning for a couple of weeks now, and i'm not sure what could be the issue? Draft? Any suggestions or similar stories out there?
