Cleaned the chimney and stove today. Didn't vacuum the stove but removed a lot of ash out of the nooks and shelves inside. Now my stove is burning to hot. Got away from me on the first load and had to remove a log and run it outside. Shutting down it isn't making much of a difference. This is my 4th year with the stove and I've had the operation down good. I know how my load will react at each air setting, etc. Not today......small and medium loads are getting to hot. I'm attaching some pictures of what I noticed. When the fire has calmed, I'm noticing a vertical burn in the center like a blow torch is underneath. Two photos show this at two different stages of the burn. The ash pan plug is beneath the "blow torch". I removed the plug today and got out built up ash lying in the surrounding hole. The only thing I can think of is to much air is getting in from the ash drawer now that ash has cleaned out?? The third pic shows the coal bed and you can see the coals in the center glowing very red in front of the "dog house" and near the ash pan plug. I don't remember this stove ever acting like this. Evidently I removed ash built up in places and more is getting in now?? Can any Englander NC-13 owners relate? And what does everyone else think?
