Good evening. We have a unique idea and want to see what kind of issues there may be. We purchased an add-on wood furnace last year at a great price with the intention of venting it through the chimney. This will not work however as our chimney is very old (1880s or older) and an inspection showed it is not in the best condition from the attic space up. On top of that, the water heater is currently vented into it, making that another obstacle. The estimates we got on repairing and lining the chimney are not doable at this time.
Details... Hotspot add-on wood furnace. Basement installation. 1 full story and an attic space above. The current chimney is in the wall between the dining room and kitchen. Next to the chimney in the same wall is where the dumbwaiter USED to be, but is now a large, open void from the basement to the kitchen ceiling/attic floor height.
Idea... move the wood furnace over and run the pipe up through the void where the dumbwaiter originally was, through the attic floor and out the roof. Use black pipe while in the basement, triple wall pipe through the attic floor and out the roof.
Questions... from the basement ceiling level up to the attic floor (through the dumbwaiter area), what pipe would we need to safely run through this? The opening is approximately 20 inches square, maybe a little larger. Will black pipe still work here or do we need to go to triple wall at this point? Triple wall is what I'm thinking we need, but wanted to be sure. How much clearance do we need between triple wall pipe and anything nearby? Same for black stove pipe.. how much clearance?
