Mark and Mike, two stoves on one flue has been done successfully a million times. There are thousands of homes with that very set up still functioning and have been for decades.

Guys I'm talking double wall SS flue pipe, with proper through floor and roof boxes. If it is properly installed can anyone tell me exactly why this is a no no? I have yet read anything that can really explain why codes and insurance company's don't like this set up. On the other hand, I have read a ton of info where it works and works well.

I can tell you we had 2 stoves on one flue at a cabin I stayed at and the stove that wasn't burning was was sucking as much air our of the room even though it wasn't lit the chimney was a masonry one not metal.
If you size the metal one properly you would need like a 10" one for 2 stoves verses 6" individually to get the proper draft.
As a ex fireman 2 stoves in one flue have been more problems than any single one for the chiminy fire results because its harder to shut the flue down to help put out the fire.

MotorSeven the problem that makes it against code in our area is the possibility of Carbon Dioxide build up. When the lower stove is burning and the upper is not gasses will try to exit at the upper stove. IF someone accidently leaves the upper stove door cracked or the seals are damaged it becomes your chimney opening for smoke and CO2. There can also be problems with the upper unit burning and the lower not with back drafting and heavy smoke smells.

If it is permitted in your area and you are comfortable with it go for it. I was just suggesting that if you are subject to code inspections or plan on homeowners insurance you should check while you can still adjust your plans if needed.

Tom, you are correct, both flues have to have airtight dampers so they can not draw when not in use. I doubt I will run them both at the same time very much. The one on the main floor will just be more for "ahhhbeeeance". The beast in the basement will do 90% of the work.

Mark, yes multiple Co2, monoxide & smoke monitors will be installed. I'm glad you mentioned the comfort level. I have done a lot of research and I think this can be done and done safely(no one wants to wake up dead). Just like heating the house from the basement, it may not work as efficient as I want. If it does not, then I can easily install a second flue into he same chase with the other one. I'm not adverse to trying the "cheap" methods first, then adjusting as needed.

Mike I couldn't find a price on the R20 boards.

Yesterday I got the great room collar ties up. I used the block and tackle again and the 3x8x20'ers went up easy. It took a few trips up and down the ladder/scaffolding, but they are in and level. I will come back later and thru bolt them with a 12x1/2" bolt.
