ok, so the next step of my planning process, is thinking about the new chimney. my friend gave me many sections of his almost brand new metalbestos 6" class A stainless chimney - I have more than enough to build mine with. The chimney will be in the middle of the house directly above the stove - and will start at the ceiling - with stove pipe connecting from the stove to it. Where can I get some good information on how to build a chase? does it start at the ceiling level or roof level? Could it be open to the room at the bottom so to better keep the chimney warm and improve draft? is this even the correct forum to ask this question? Thanks!
