Other thread has gotten quite long so I decided to start another one.
Any of you have your secondary flames shut off about an hour into a burn?
I can load up. Top temp. with IR about 650-700*. Air shut 75% of the way. Secondaries burn nicely - rolling along the top of the wood. About 1 to 1 1/2 hours I suddenly will loose the flame on the bottom that is feeding the air tubes and all flaming stops in the firebox and smoke starts coming out chimney. I have to open it up 1/2 way to finish off the burn.
No fans are on in the house. No dryer or other things requiring combustible air - I checked that after someone suggested that may be the problem.
So now I come to you since you are all burning with the 550.
My chimney in internal masonary and is 15ft. straight up. Wood is 20% or less hard wood.
