hi CC

I had a barometric damper on my stove. I tried reducing the fire box to maybe 60% but I didn't really see any big benefits to it. I had no trouble idling a full fire box down to almost nothing after 5 hr with the knob turned open less then 1/16 I could put my hand on the coal and hold it there for a few seconds. Then when I needed heat just open the ash pan door for 10 mint or so and it would glowing orange again. I think it was a lot easier to control the fire with a full box then it was with it reduced.

Thanks for the info. I suspected the reduced fire box could be affecting the burn. It's good to know it will really idle down with a full firebox. I'm sure I'll get her figured out in time for the cold weather. The forum has been a big help.

Good news .... using windowstats (LOL) is not uncommon. Also, is that rug flame-proof? Hot coals get on it and you could be in for a hassle.

What hassle?........some people like hard work and exercise (running for water hoses, buckets of water etc.). And some like real exitement in their lives..........heck, some even pay for the rush of exitement that a living room fire can cause. :eek2: :junmp: ;)

Thanks for the warning peeps. It's a fire retardant mat please erase visions of my pending living room fire from your minds. I like a little excitement but not that kind. On a not so funny note, my neighbor just lost their house 2- weeks ago to a generator fire. Power went out the neighbor started a genny under his deck next to several cords of wood stacked against his outside wall. Within 30 min it was a burned out shell very scary stuff!! No one was hurt thankfully but our hearts go out to them! Fire and fume safety is no joke. Please think it all through to protect your family and you homes.

Back on subject
I removed the firebox restrictor, filled the stove to top of bricks, cut the blower way back, added a little more secondary air and the stove is running much better. It's gonna take a little time to iron out all the wrinkles but we're on our way!
