So my husband was home for a chimney install quote today (our first one) and the "recommended" installation is leaving me scratching my head. I wasn't there at the time and now wish I was, because this whole install sounds crazy. But maybe it's "normal" and I just haven't seen it before. Have you guys? For aesthetic reasons, the guy suggested to install the chimney straight up into the second floor (which is only a half story so it has cathedral ceilings and is rather tiny) but once it gets to the rafters bend by 30 deg and continue along the rafters until it clears the peak, and pop up on the other side of the roof ridge (which is maybe 10 feet from where it would enter the second floor). It's baffling to me that the guy recommended that. And that my husband didn't even bother to think about clearances and such. The upstairs bedroom has limited room to begin with. Is this guy crazy or is this a normal type of install?
