Terminate at least 3’ (0.9m) from the
combustion air intake of any appliance
and any other building opening.
Enclose exterior vent systems below
the roof line to limit condensation and
protect against mechanical failure.
When the vent penetrates a floor or
ceiling and is not running in a fire rated
shaft, a firestop and support is required.
When the vent termination is located not
less than 8' (2.4m) from a vertical wall or
similar obstruction, terminate above the
roof at least 2' (0.6m), but not more than
6' (1.87m), in accordance with the National
Fuel Gas Code ANSI Z223.1/NFPA 54.
The aluminum flex pipe serves as
protection against damage.
