This is the chimney - interior chimney, 8x13 flue liner, 6" ss liner, 30 ft tall. I posted here about a chimney fire last year, but have not fixed anything yet. Had a stove guy look at the chimney, said he saw some bad tiles, and that I'd need a double wrapped liner. So, given that is correct:
If I were to ovalize the existing liner, I read on this site that it works to use a piece of pvc and roll it down the pipe. How much though? Do you make a frame or channel out of 2x4's or something so you know how much to compress it? I think I'd have to ovalize to get a double wrapped liner down the flue, right?
When I mentioned to the stove shop (that quoted me 2k for a wrapped oval liner installed), I asked about vermiculite or an insulating pour in product, and they told me it wasn't sufficient because you can't know if the liner is centered in the product, or if it's touching the clay tiles. So if I were to get thermix or vermiculite, would I be able to jiggle the liner around enough in the chimney to get it completely surrounded by the pour-in insulation? I'd much rather do this that pull the liner, bend it, wrap it twice, and hope I'm able to get it back down.
