I finally went into my attic to check where my chimney will go. (Remember the installer visit, where he didn't need to check my attic, saying they could take care of any structure that was in the way?) It does not look good! Not only is the flue centerpoint about 2 inches away from a ceiling 2x4 and a rafter, it's also directly underneath some important-looking beam thing running the whole length of my house across the ceiling 2x4s. (I don't know house construction terms, so I'm just describing what I saw.) My house is a normal, rectangular ranch, with a wall along the long centerline. Then midway between the center wall and the outside wall, on either side, there are 2 or 3 2x4s nailed together, which sit on top of the ceiling 2x4s. That's the "beam thing." Before I visited the attic and realized that there's a rafter above, I'd only imagined cutting a ceiling 2x4, not interfering with rafters and roof support. Now I have this beam thing, AND a rafter, and I figure I should just offset my chimney. I really can't move my stove more than a couple of inches--the spot is really tight. Does anyone have an opinion one way or another? Should I take pictures, or do you know what I mean by my descriptions? Thanks a lot!
