I have an 8"x8" lined chimney. WAY too much for the NC30 (18' from the thimble up.) Inside is the 30, connected with 45°'s to the thimble. Clay tile looks really good, no build up, etc. But its WAY to big to get a good draft. I just wasn't sure that rigid would fit. So I got a paint can that was 6.75" and lowered it down. (I read it on the internet somewhere, great idea!) It went down pretty simple, now to order the liner. Hoping to have it done before Christmas. I am leaning towards perlite for insulation. Unless there could be some benefits to the vermiculate/portland slurry. Will get 5 - 4' rigid sections for above the thimble, and a 36 for below as the clean out is inside. This will also hopefully add an additional 2' to the chimney height.
I just had a chat with Woodland Direct (out of Michigan.) Very helpful young fella. He had a few helpful suggestions: Stainless Steel - Self Tapping Sheet Metal Screws to assemble the liner (no rivots needed) He suggested no less than 3 screws. I plan on doing 4. Crimp side down Using a tow hook and rope it can be a single person install (The tow hook/rope to hold the liner in place while you add on the next section.) Only spot silicone is needed is the Rain Collar, and the 8x8 Metal Top plate that goes over the existing clay tile. He made a comment asking if I was a GC, stating I had a good idea of the process. I gave all the credit to the FHC crew , while I may not post often, I am constantly reading. We had a bit of a chat then after and I brought up the dry wood topic. He says " YOU are the type of client we love to have."
Install went pretty smooth. Even won a case of beer, as my cuz didn't think my perlite calculations were accurate. Turns out they were, I estimated 4.4 cubic feet, ended up needing about 4.1. (He bet we would use more than 8 cubic feet.) Got the 30 going strong arm, with a nice load of mulberry. REALLY nice to open the door and not have smoke spill out.
Yes, 6" Rigid Rhino, made in PA, then shipped to me via Michigan. 23' total, 20' after the 90 I had a pristine 8x8 clay tile masonry chimney too run the liner down.
Nice work. Just did an insulated liner recently, with busting out all the clay to fit it. What a job.
Yeah, that doesn't sound fun. I used ceramic insulation at the bottom and perlite to the top of the existing clay, I would not have been able to fit wrapped liner down the clay.
It's not to bad really...... custom fitting on a drill with iron cubes attached with a little chain. Busts right through. Gotta keep cleaning out the clean out little by little. The clay gets jammed in at the bottom easily.
