Generated explanation

A cross section shows a brick masonry chimney with a flue liner extending above the chimney cap. The cap slopes inward toward the liner rather than outward toward the chimney edges. Rainwater is shown collecting at the liner and descending into the space between the liner and masonry. A large red prohibition symbol marks this cap configuration as improper.
