So I want to get some opinons on this. The cap that fits on my liner recently blew off the chimney. The only thing that was holding it on was the rutland fire safe caulk that I put on the edge of the top of the clay liner. It worked well until this year. I was going to go back up and reaffix things, but I was wondering if there would be any downside to just using the original chimney cap. It holds onto the outside of the chimeny with bolts.

I got mine from fireside chimney supply. There was a plate that they said just to caulk to the top of the chimney tile liner that sticks to about a foot. They advised against drilling holes indu the thin clay liner. So then i put the cap on that plate.

Isn't that what he meant in the original post, that the top plate was silicone to the terracotta liner, and it is that weld which did not hold?
Be sure the top edge of the clay is clean and dry. Then put a very thick and consistent size bead of clear silicone on the clay edge. Let it sit for a couple minutes to firm a little. Then lay the plate on top and evenly press into the bead until it it compressed about 50%. Do not compress so much that it squeezes out or so much that the plate contacts the clay. Let it cure.

THAT is exactly what I did as far as keeping my original CAP. I ordered the liner kit and the cap that came with the kit was not anywhere near as heavy and well built as the cap I already had so I used my original cap. I know for sure that it is the better cap and has been performing just fine.
The plate gets sealed down with silicone, then it should clamp to the liner. Even without the seal holding it shouldn’t blow off.

bholler, I haven't been on for a few days but yes I did use the top plate that came with the kit. It fit my 13x13 tile perfectly with maybe just a little overhang. I used sealant up there recommended by the old dude at the dealer. The space between my liner top plate and block off plate I constructed inside the firebox is dead space now. I am not bragging but I think I have a pretty good install especially with the burn times I am getting. Hell, my co-workers and family are so sick of hearing me talk about this BK insert its funny. One thing I was worried about was could my wife run this thing? Well, the answer is yes, she is able to run the Princess with no problems and she likes it as well as I do.
