A few may remember I had new chimney liners installed on each of my old fireplaces containing woodstoves in October. On one of these, he was to install an insulated 6" smooth-wall flex liner with blanket wrap insulation into my existing 8" ID clay tile chimney, and connect to stovepipe. When I saw the completed job, and noticed he was still running the stovepipe up to my old block-off plate for the 8" chimney, and had stuffed gasket rope around the gap, I had asked him what he had done there. He had basically told me that he had connected the liner to the old block-off plate, since the stovepipe was already set up to connect to that. Well, tonight I pulled it apart for my mid-season cleaning, and was blown away by what I found. First, three sections of stovepipe, with NO SCREWS in any of them. They were just sitting as gravity held them on the stove collar. Second, there was no fixed connection between the liner and the stovepipe. He had cut the liner too short, such that it ended just ABOVE the block-off plate. He had crimped the end of the liner, so that it slid into the ID of the stovepipe (which is not bad in itself), but had again used NO SCREWS! Unfortunately, since that junction is above the block-off plate, which is bedded in mortar and stone and butted directly against the bottom of the 8" clay tile liner, there's no way to even install screws there if I had wanted to. So, I think what I have is a chimney that works just fine... as long as there is never a chimney fire. I suspect the reasoning for the screws is to keep things together in that unfortunate event, and prevent a chimney fire from quickly turning into a house fire. The only solution is to pull the existing liner, and install one that is at least 4" longer, so that a proper connection may be made between the liner and stove pipe. What to do about it? This guy is already pissed with me for (1) making him go back and buy the smooth-wall flex I had requested, when he incorrectly bought standard flex for the job, and (2) making him come back in the early stages of a hurricane to pull off a flagstone chimney topper that he had done a very poor job in setting. He's very highly recommended and reviewed, and seems to be a dead-honest guy, but perhaps not very bright! He is CSIA licensed, although after seeing this, I honestly doubt the importance of those credentials.
