I'll take a picture tonight... the heater sits probably 4-5 feet tall and has about 8 feet of piping sticking up above it. (making it about 12 feet up right now) The roof is about 16 feet up. No Drywall to cut through, just rafters, and then Metal with bubble insulation for the roof. I know I need to pick up flashing, storm something, Class A piping for outside, extra piping for inside, and the cap for the chimney, but i don't know what else would be needed if anything.
