I have been burning wood for 40 years but only in the last 5 years or so have I had any of the new fangled stuff. Just a wood burning box and a chimney. Always kind of went by my gut instincts. Now that I have all the "stuff" I am trying to correlate it to what I have always done in the past. Tonight I put a load of ash in the stove and came in here to check hearth.com. Hadn't been very long and I smelled HOT. I have been burning oak and hickory and just got to a some ash in the wood shed. Well, that stuff takes off a lot faster than the oak and hickory and it took me by surprise. The smell was my stove pipe (double wall), It was 400 on the outside, 1300 inside, probe thermometer reading. Stove top was only 500. I shut it down and everything cooled off right away. I have done that many times in the past but had no idea what the temp of HOT smell was. So, how high have you guys seen?
