Then install the 8" round that I want to use right? Then no insulated thimble through the wall. Just hook up the single wall to the 8" round thimble like a normal chimney that is installed inside your house. Correct me if I'm wrong.
That is correct......Of the different ways I've done this, and seen it done, in my opinion, the way I explained is the best. There are other ways to go through the wall. If it were my own masonary chimney, I'd do it as I explained. On the other hand, I would not install an exterior chimney. That is why I put the metal chimney in my place. I've got the perfect clearances to go straight up through a closet, and out the roof, without any modifications to the structure. The problem is, I'll be replacing the metal chimney in another year or so. I sure hate the thoughts of putting another metal chimney back in. But, it fits my situation perfect.
