Has been hot here the last few days, mid 30s even so minimal use of the stove, 2-3 splits in the evening and that's all that's needed to keep the house warm. Got home, fell asleep while taking my boots off pretty much. Woke up it was around 8PM. Was a bit chilly in the house (65ish), outside temp was dropping. Threw some wood in the stove, was a bit of embers in there so it would start at some point. Went in the bathroom for a few mins, had the fan running and started to smell smoke. Had smoke coming out of the stove and living room/kitchen was smokey Have had this happen when it's warm out... tightly sealed house so it pulls air from the stove even with an OAK. ("air tight" isn't exactly true.. it wouldn't be remotely close to water tight, never mind air!). I usually leave the window by the stove cracked open a bit just in case if it's in the 30s out. Not normally an issue if just one fan is on, but if the dryer is running as well or if both fans are on it sometimes will do it (not always though) Dunno what it's issue was this go around, 15* out.
