The mortar joints between the liners are shot. And thats an 8x8 so probably 6.75 or so square. I wouldnt install a stove in it.

That was my first thought. Breaking it out and drop a liner or new roof penetration. If DIYing the later is looking better. Now I get to choose the perfect location.
How can you tell ? By comparing the size of the chimney cap with the bricks ? You wouldn't install because immediate fire hazard, or just because there's likely to be a lot of creosote buildup because it's so un-smooth ? Were they full of it when they said "In good condition with no apparent issues" ?
Gonna be hard to sell either one to them. I think they're just gonna hook it up and hope for the best.
But I like the "new roof penetration" (aka. all-metal chimney) option. Maybe $2000 of parts (see attached shopping cart snapshot and assume I've missed a few minor items). Seems pretty DIY-able, the crux issues being: flash the roof penetration well (easier since it's shingles not metal), support the support-box firmly, and make sure there's no combustibles within 2" of the pipe.

I can tell by the pics. Its square and by looking at the top it clearly isn't a 12x12. I would strongly recommend a liner for performance reasons. But refuse to hook a stove to it because there is no mortar between the clay tiles

I have the opinion, warn them. If it doesn't work, they were informed. Sometimes some improvement can be achieved, but at an expense.

The stove they have there now works (see the pix in the doc I attached in post #24 above). But as we all know, the BK is a totally different animal from some thing picked up for $80; in particular, they're going to want to be able to take advantage of its ability to do a long slow burn. More need for a good strong draft and more potential creosote buildup.
I really think a new metal chimney is the answer. I'm going to start a new thread.
Yes but your just selling it. As the guy installing it i am liable if something goes wrong. So obvious safety issues I won't do it
Did a MODERATOR move this thread to DIY ? Doesn't seem like the right place; maybe I did it by mistake.

Yes but as the guy doing the work I have liability issues to consider. If its just a performance issue sure i will hook it up telling them it may not work well. But im not hooking a stove to a chimney with a failed liner

I think that was the concern here when I asked about getting my original masonry chimney approved. The guy said he'd have to take it apart before he could say it was OK. Now I see that he was probably not able to approve the liners? That put an end to that idea. Now there is an electric fireplace covering the opening, and a new pellet stove install in the basement. I guess I could still get some sort of insert, but I don't hang around in the living room anyway.
