I completed the overhaul of a second hand fired Franco-Belge by mixing and matching parts from three old stoves.(If I didn't think I might need some of the leftover parts in the future, I could probably make some money selling them E-Bay.) The two stoves are now side-by-side ready to be hooked up to the fireplace chimney. I have probe thermometers for each stove and I will connect the Dwyer manometer that just came via UPS. I do, however, have a thought about the barometric damper.
On other threads, people have spoken about a fresh air supply for combustion air for safety and also for efficiency. What about hooking up my baro damper directly to outside air so that I don't waste any room temperature air. I know that the way it currently operates is the lesser of two evils; rather than waste superheated stove air and disrupt the rate of combustion, some room air goes up the flue instead. If the baro was hooked up to outside air, none of the room temp air would be lost.
The only thing I can say against this idea is that maybe the ice cold air would drastically lower the flue pipe temps and disrupt the draft of the chimney. Any thoughts/comments would be appreciated.
