Okay, back to the liner. So what we have here is a small dent that doesn't appear to have affected the integrity. SO - NOW what is your next concern? Is it that it is spaced to close to your cap? If so, can the liner be pulled back in further? The top cap looks like it was never sealed. That would also be of concern to me. Lay it on us. The next question is....
 
I put insulated liners down 8"x13" flues pretty often, it's very tight but it goes. I would pour it in if it was me though, since the liner is ok. You will need to make sure it is sealed VERY well at the bottom of flue, otherwise the whole smoke chamber will fill with insulation and possibly over load your block off plate. If that is what you want to do, then make sure the area behind the damper is back filled or sealed somehow before you start pouring. It really stinks to start pouring and then find out that you are way to short.

How do I know it hasn't affected the integrity? Seriously, how would I be able to tell without pulling the liner and visually inspecting it? Seems to me the entire install was a poor job. Even if it's ok,the liner was short, the top cap wasn't sealed, there was no insulation on top or at the damper, the 90 adjustable was busted wide open when I pulled the stove, etc, etc. Yes, I feel the space is too close to the cap, but I'm no expert, just seems 3 inches is too close.

Ok, rant over. Next question is " Can you come over and help me pull this liner and put in a new one?" Just kidding man. I got the feeling from the experts on here that I was nickle and diming it, cutting corners, and I probably was, so I'm starting from scratch and I'm going to re-do it myself. This way, I'll do it how I would like without these chimney guys telling me otherwise. For example, I had a local companny come over and explain to me that they always use regular pink unfaced insulaion at the damper, the next said don't waste my time insulating the SS liner, and so on. So, with your help and guidance I plan on getting this accomplished. I just need to remember to s-l-o-w d-o-w-n.

Actually, I do have a question, can I use roxul to stuff down my flu around the SS liner as insulation?
 
The Roxul won't cut it. It won't fill voids like pour in stuff will. I don't have my liners insulated but have Roxul at the bottom and the top. I pushed some of the stuff down during the install and it is hit and miss and mostly a useless effort. I just needed somewhere to get rid of the rest of it.

And I seem to be the only one saying it, but I say it again. Get you a liner kit and replace that thing. You don't trust it so get it out of there. Sleeping at night is better than staring at the ceiling.
 
I agree and that's my plan. I plan on installing a new insulated SS liner with a block off plate. Made a template tonight for my block off plate. So, I should still insulate the damper and top cap even though my liner will be insulated, correct?
 
Yep.

Not so much the top plate but for sure the block off plate. But the stuff does help inside the flue tile where it is exposed at the top.
 
If you are pouring in a vermiculite/perlite, you won't need Roxul on top of the block off plate. I suggest you stuff Roxul or stove door rope into the gap between the block off plate and the liner. You can even use the door adhesive on the rope to keep it from moving. Without some kind of seal, that poured in insulation will continually find it's way through the gap.

As mentioned above, make sure that block of plate is strong enough to support the weight of the insulation, especially if you decide to use a Thermix type lightweight concrete.

Another option is to pull the existing liner to inspect it, then if it's ok, ovalize it and wrap it (or maybe wrap it, then ovalize it?). See http://www.youtube.com/watch?v=vAIjcN8HqDo for an example.

Thanks guys! My final decision is to install a new liner with insulation wrap, install block off plate with roxul above and also use roxul at the top.

Sounds like a plan (with my prior post, I was actually trying to get you to commit to a plan :coolsmile: )
If you do what you say your going to do - you will be in fine shape.
 
Rak,
I'd say this thread worked well for you. Good luck with your install!
