Hi everyone I am new to the Hearth room. I have the Harman :coolsmile: n TL300 and I have been burning with it for four years now. I burn anywhere from 7 to 10 cords a winter season. Over the past four years I learned allot about this stove. One of the biggest problems that I recently encountered was the stove dying right out once I loaded the stove with dry hardwood. A two inch coal bed was already inside the stove. Once I closed the damper lever the stove would starve for air. I called the dealer and They did not know anything about the wood stoves they sell. Frustrated I went home And tore the inside of the stove apart. All 4 12 inch fire bricks were removed first then the back fire bricks. the last brick you remove is the shoe brick. That's the one with the holes drilled in them. Once the shoe brick was removed I saw 3 inches of ash behind it. The problem was found. The After burner could not get the air it needed once the damper was closed. Most important to use a soot vacuum to clean out ashes along corners to make sure the fire brick goes back in flush. I put all the fire bricks back in and started the fire. Once the stove was up to operating temp closed the damper and the after burner took off YES
!! Upon inspection of after burner chamber i saw a pea size hole in it. The after burner chamber is really only good for 4 years if you are a heavy burner like me. If not you can get 8 years if your lucky. Rule of thumb with your coal beds do not let them get 3 inches deep. Why? because it will go over the shoe brick causing the stove not to run right. The next thing I will do once the burning season is over is removal of the Afterburner chamber. Let know one fool you the back of the stove has to come apart. Harmen is the Porche of wood stoves yes. and that comes at a price. DEALER ORDERING PARTS$$$$$$. If you are a Harman owner and is having a problem let me know.
