Does a chimney need a liner when clay deteriorated?
Hi,
I have a very old interior brick chimney for natural gas-fired boiler. A chimney contractor who cleaned it for me said he saw just some remaining spots with clay, but most of chimeny left with just brick. He said I need to install a liner. Just wanted to double check if it is indeed needed?
I do see a normal draft when I check, and my carbon monoxide detectors never activated.
Thanx.

Chandler,
Thank you for the reply.
My chimney contractor said my chimney can fit 6"D steel liner (maybe 7"D maximum), but my boiler vent diamater is 8" and its manual recommends likewise 8" chimney. Is it a problem if the new liner diamater will be lesser than the boiler vent?

Not my area but I would think going with a smaller diameter than the manual indicates would be a bad idea.
