Okay guys, I need some advice. I just installed a Hotblast 1557G. I was burning up a box full of wood in 4 hours, so I called the factory and was told to put a damper in the chimney pipe and a barimetric air regulator on the chimney pipe. I have done both. The fire in the box was really taking off with the damperopen, but I can't seem to get much more than luke warm air out of the blowers. I know there is an art to getting the right tuning going to really produce some heat, and that's what I'm looking for.... I have an air inducer on the firebox. Should I be having it on? How many turns should I have the ash door damper open, if any? It has a blower thermostat with 3 setting pegs. What do they need to be set on? Sorry for all the questions, but I am (or was) a Florida boy and I gotta get this thing working, if you know what I mean. Thanks

Bruce4444,if you are burning wood, you shouldn't need a Baro Damper, just a Manual hand damper , which should be between the baro and stove, if you have both, not the other way around!. If you have the Manual damper above the Baro, you could cut off the exhaust and it would leak out the Baro Damper into your house! :(

The baro can build up with creosote and not work correctly, and if you were to have a chimney fire, the baro would let more air in to fuel the fire up the stack.

I used the equivalent to your furnace for many years in my unfinished basement.While I realize Baro's are frowned upon in wood fired appliances, without one my furnace was useless. I had an external Duraplus chimney with so much draft I could never keep a fire more than 5 hours and literally all my heat was escaping up my chimney. This was with prime, well seasoned oak/hickory. I installed a baro and my furnace instantly became a viable heating source, where it wasn't before. I still wasn't completely satisfied and added an outdoor air supply, and wow, all the sudden I was turning back the bi-mettalic to avoid overheating the house. I kept my baro flap reasonably clean with a small wire bristle brush. By burning quality well seasoned wood it really wasn't much of a chore as I had minimal build up throughout the season. It literally took me from a useless furnace to a very effective system for a minimal investment of time & cash.

I appreciate the input. The factory has the baro damper first, then the solid one in the pipe, so that's how I installed it. I just can't get a lot of heat out. Do I always keep the fan on that forces air into the fire box?
