Off the computer topic here,
but on topic of not burning your house
down, there is a code required keepout between chimneys and hot exhausts
that must not have combustibles there. If you are in a situation where
they took an old brick chimney and lined it with a stainless insert it
probably isn't the problem you would have if it were not. Usually they
don't trust masonry w/o lining it after it gets old for gas and heat
leaks anyway.
But if you are running something the creates creosote inside the system,
you might have a fire which could set off your conduit if it isn't
fireproof. Creosote fires for wood are common if you have the right
conditions.
I have a house I can't get insured because of old masonry chimney which
isn't based on the ground. but that's a way long off topic story.
