The previous owner installed a 80% effiecient furnace and vented thru an
existing chimney. He didn't install a flue liner. SO...after 20 years, the
inside of the chimney starts to drop bricks (from the acidic condensation)
and partially obsturcts the flue. (Boo to the homeinspector who didn't spot
it before I bought). Because of the partial obstruction I chose to have a
liner proffesionally installed. Took half a day and cost $800 (northwest
suburbs of Chicago). The obstruction didn't seem to cause them any
difficulty

Anyone installed a Flexiliner or similar flue in a brick
fireplace? Did you do it yourself? If so how hard was it
and what did it cost? IF you had it done what was the cost?
