Hey guys, I have a question about an install I'm trying to help BIL with. He's got a log home with a 24' vaulted ceiling. The wall that the stove is going against is all glass ,like an A-frame. The ceiling is exposed ridge beam and rafters with I'm guessing 4" tongue and groove decking with metal roof on top. Putting the stove as close to the center as practical to save money on expensive double wall stainless(more black pipe inside than double outside). Now to the question part, whats needed to go through the decking and metal roof? I'm guessing a cathedral ceiling support and just a couple of sections of double wall with some type of flashing boot, and of course a rain cap of some sort? Thinking penetration maybe 3' from ridge beam. Don't quite know the spacing of rafters, haven't been there in a while. Whats your thoughts? All input welcome. Thanks in advance guys.
