So the clean air retards in my area seem to think that they need to further restrict solid fuel burning in an effort to clean the air in the urban centers. I live way outside of the urban centers but in the same county so my 100% wood heating lifestyle is at risk. I am forced to consider options. I have no natural gas available and no central ducted heat source. My current woodstove is vented vertically from the stove to a ceiling box, then simpson class A pipe 8 feet to the cap. Total chimney height is about 14 feet. If I were to remove the hearthstone stove what would be needed to install a propane stove in its place? I have a 3" outside air connection from below. I would need to install a gas line but what about the chimney? Is it too tall?
