Is it optional to use clamps on my sections of class A chimney?
I fully plan to clamp all the exposed joints, but what about the joints that aren't exposed?
I'll explain the situation a bit. Installing a ZC fireplace that will be enclosed in a stud wall (no access). I have 1 section of chimney that goes up to about 3" below ceiling level. If I clamp this section I won't be able to pull the chimney up through the attic insulation shield if I ever need to remove it. I also won't be able to pull it free from the stove if I clamp it to the stove-top connector.
So here is my thought. The Duratech chimney already connects very tight and securely without the clamps. When reading the installation instructions I was given the impression that they were optional. So my thought is that if I leave the clamp to the stove and the first joint off, I can always remove that first section of chimney by reaching down through the insulation shield and pulling it up through into the attic.
Is there anything wrong with this approach? Will my chimney be properly secure without using the clamps?
