Nice way to disguise ugly vent pipes - not painted yet
The local gas inspector vetoed the coaxial vent pipe and insisted on a two-pipe system. My installer put in the new pipes on his own dime, but was not happy with how they looked (they are visible from the street). So he paid for a carpenter to build a slick enclosure. Once I paint it to match the house, it should blend right in.
