Hey Everyone, Admitedly I am still a total rookie at wood burning but have the bug really bad. Even after reading a TON of threads I still am having trouble getting a really good hot burn while dampered down and am looking for some advice. I am burning in a FPX 33 insert with a double walled SS liner that runs up a masonary chimney. I have a block off plate installed up top. It is impossible to find a good place to put my stove top thermometer on this thing! Its even tough to hit the stovetop with the IR gun with it... The stove is in a large room with a cathedral ceiling - about 17 feet at its highest -picture attached The wood that I am using is made up of mixed hardwood and ranges between 17 and 19% MC on a freshly split face. I can get a bit OCD w/ adjusting the stove Here is where I am stuck. Starting with hot coals from the last burn I remove some ash and rake them foward. Due to the shape of the firebox I am basically forced to stack the wood in a E/W fashion. I load it up as much as possible with large splits in back, medium in front of that and small in front of that - usually covering the doghouse. I close the stove door. At this point I the air control and bypass fully open. Within 15/20 minutes the firebox is full of flames and the stove top thermometer is approaching 400. I close the bypass and start closing the air control in my 25% increments. I wait longer and pull out the air control again and again. At this point (about 75% closed now) I have minimal secondaries (sometimes) and small yellow and blue flames on and over the logs. The stove top gets up to 6-700. I'd like to close down the air even more but when I do my flames totally die out - even if i do have secondaries going when closing down. I'd really like to be able to close down the air more to extend my burn times and get more extended heat out of the unit but cant keep the fire going when i do! I run the stove fan @ about 75% Based on peoples experiece should I expect to be able to get my stove room warmer than 72 degrees when it is 20 outside? My house is at the upper range of what the stove is rated to heat... Thanks everyone!
