That is by far, the dumbest thing I've ever heard. Well, ok, maybe not but it's still pretty dumb. I wouldn't put an SS liner in. I had one, it lasted two seasons before it pin holed. My chimney is currently 12x12 18' tall and has a terracotta liner. It also doesn't draft well. So, I put a draft inducer on it.
I agree, stupid by far and my neighbor thinks his son's buddy is "doin' the right thing", I will tell him about the draft inducer, thanks!

Code requires that clay tiles be set before each one is completely surrounded by the masonry chase; this in effect, prevents the code-approved relining of chimneys with tile. Like other gov't regulations, codes are not immune from a few powerful companies and interests (in this case stainless liner mfg'rs and "chimney professionals" - many of whom wouldn't cut it w/ traditional stone or masonry chimney work) using the gov't to create laws and regs that benefit themselves.
I would advise two things: 1. check the height of the stack, I've dealt w/ "oversized" flues before, the problem is rarely the flue diameter, but rather the mediocre height of the stack compared to the structure or the draft requirement. 2. If the stack is tall enough (4' above the highest portion of the structure, and at least 18' tall) then forget code - reline with tile, pour vermiculte between the two tiles, and once done, the stack will "meet code" but the process (which no one knows about) will not.
His stack is fine he is across the street from me single story ranch and his chimney is 3-4 ft. taller than house same as mine, my flue's are 8x8 terracotta and I pull .04 on a calm day. I could see post inspection of a 100 yr. old chimney that you could see through, that a s.s. liner would be mandatory but his chimney is only 8-10 yrs. old on a new addition. I suppose someone thought bigger was better and he didn't know better. I wish he would get on the sight and find out for himself. You know what they say, blood is thicker than knowledge!
