I have a question to why I get a huge slow motion rolling fire burst of flames and very quick puff of smoke comes out of the primary air slide on the lower front of my stove door when I closes my air all the way shut. It looks so strange when this happens. Make the house smell smokey too. My stove is an Appalachian 52 Bay ( cat insert ) The way you adjust the burn there are 2 primary air adjustments on each side of the door that lets air flow up inside the door and out through these little holes at the top for the door for the air wash. This only happens when you close the air off all the way and loaded the stove with wood. Am I starving the stove of air ? If you open the air just alittle no problem. This stove is new to me and I am in the learning process. I have read my stove manual and follow what it says. Wood is 2 year old seasoned and I wait for my cat temp to reach 600 to 700 before I engage. The only thing I can think of that I might be doing wrong is I'm closing the air off to quick.
