Sorry for the delay in answering.
My stove generally keeps the water in my oil boiler at around 170°on average, but it will range from 140° to 195°depending on the outside temp., demand for heat & demand for hot water. I do not pay any attention to the gauges on the boiler or the markings on the knob that adjusts the damper door. The temps that I mention are the temps in the oil burner so it may be higher in the stove. I also have a barometric damper on my flue which steadies out the burn. At 170° my damper door is closed and the stove will maintain that temp. with no demand. Once the heat or hot water comes on and the temp drops the door will open up to let some air in again to fire it up.
I don't like to rake the coals. It seems like every time I do the coals pack together too tightly and choke off the air. Too much poking can have the same results. The coal needs a good flow of air through the bottom and if you choke it off with ash or packed coal the fire will go low and eventually out.
After poking I fill the stove to just above the level of the bottom of the loading door. I'm guessing that thats about 30-40lbs.

On second thought, it is probably more like 40-50lbs.

Hi All, sorry to make a zombie thread.

I have been lurking for a few months as I researched my new, to me, Biasi 3-wood boiler.

The person whom owned it before we moved in only burned wood in it and it looked like it produced creosote like crazy ( which seems to be the trend with these when burning wood). I will be burning nut anthracite, after I get the chimney swept.

Anyways, here is my question, earlier in this post someone mentioned putting in a barometric damper and asked if it was ok to put a 6" one? No one seemed to answer him. Seeing how the Biasi has a 7" output I was wondering if it is ok to reduce the pipe down to 6" and then I can put in a Tee with a barometric damper. The 7" is really hard to find, and It seems like the 6" dampers are easily found and cheap. I suppose I could increase to 8" If I need to.

Thanks for any help you can give! This is my first winter burning coal. I recently moved to Downeast Maine. I am sure I will be back with more questions as I start burning this winter.

You should keep the flue at the 7 inch size. They do have dampers that come with a tee that gets cut into the pipe that are not too difficult to cut in. I would do that before reducing to 6 inch. I have been burning this boiler with nut coal for a long time and we love it. If you have any questions you can private message me also.
