Folks I have a weird question. I want to put my Vigilant stove in my pole barn and I need to locate my chimney. I would like to keep the stove by the eave but then I have 2 questions. 1. how high above the roof line does the chimney have to go if I have a 6:12 pitch. 2. will ice slide down and try to rip off my chimney...and if so should I put ice catchers on the roof from the chimney up to the ridge?
