Hi all, I have a 12 year-old Dovre Cape Cod wood burning stove with the manifold air tubes. This stove was manufactured by Aladdin Hearth Products who I believe changed to Quadrafire shortly after I purchased the unit. It has two front glass doors and top vent system. I am using 1 inch Kaowool blanket on top of the 3 metal plates that sits above the manifold tubes. The 1 inch blanket is about 8 years old, the stove originally came with a the 1/2 inch blanket but it was difficult to locate for replacement.

Well anyhow I had my stove cleaned last week and used it for the first time this season. The tubes were removed for cleaning from the inside...this has been done by same chimney sweep for 6 years.

We had a major issue this evening...I think. I had a pretty good bed of coals as the inital logs were almost burned; just one remaining half log was burning. I added another log on top of the half burned log and on top the nice bed of red coals. After adding the medium size split log, the stove really took off. I backed the damper all the way down to reduce air flow. The start-up air control was closed. But I couldn't control the flames. The air tubes were glowing red and the gases were rolling in the stove. Also the back air tubes where the start-up air comes in was also showing signs of air and rolling gasses/flames hovered around the rightside tube.

I beleive the fire should have completely backed down and the rolling gas flames should have stopped when the damper was moved to the least amount of air position...Correct?

I have not had this issue before and it concerns me that I was not able to completely stop the gases/flames from rolling in the firebox. I ended up grabbing the log and placing it in metal copper tub and quickly escorting it to the outside.

Does this issue sound like a worn gasket door issue or a problem with the start-up air control not closing all the way? Any other ideas? How would I go about checking the air control mechanisms?
 
Welcome. It could be that the coal bed needed to be burnt down a bit more. Was the split a different species of wood that was drier or more volatile?

I would watch the stove and see how it performs with different wood. If it still seems less controllable, then check the door gaskets with the dollar bill test.

No, same oak wood I have been using for the last 2 years. Wood is very seasoned and was dry. We will run out of this older seasoned wood this winter and have some seasoning for next winter so that it will be over a year-old. Learned the hard way about less than a year-old seasoned with these EPA stoves. :) Can you expand on the dollar bill test?
