Hi everyone I am installing a wood stove for my first time and I am making some good progress but I am stuck on one thing. I have plenty of clearance for my single wall pipe all the way from the stove to the ceiling, but at that point do I need to hang the support box 18” out of the ceiling in order to maintain that clearance? I want the box to be flush with the roof or slightly above it and completely seal off the chimney pipe but then I will only have about 4” sticking out from the ceiling. Is there a box where I can extend the chimney pipe down into the room? Any help is appreciated thank you.
