WBH,
I re-read above, really, you are burning 7 full cords, damn, that's a lot of wood. I had about 5 set up for this year and it's more than I'm going to use, my December row in the shed is still going strong and will go well into January. You should let that puppy go full out one afternoon and really carefully inspect everything. Something is just not right if your wood is dry, look carefully at all the doors for ash buildup and proper sealing. I understand leaks would tend to make for too hot out of control fires but, you never know. Anyway, just a thought!
