The exhaust and combustion air terminations must
follow these clearances:
[1] 12 inch minimum vertically from bottom of exhaust
termination to top of intake termination.
[2] 12 inch minimum vertically from bottom of
combustion air termination to ground or anticipated
snow line.
[3] From edge of exhaust termination to edge of
combustion air termination:
Minimum of 36 inches
Maximum of 20 feet
[4] 36 inch minimum from multiple exhaust CVents
There should be a minimum of 36 inches between
exhaust terminations in multiple common vent
installations.
The vent (exhaust & combustion air) terminations must
be in the same pressure zone and face the same
direction.
NOTE: During colder weather when the exhaust tem-
perature is much hotter than the outside air, the
exhaust fumes condense producing water va-
por. As a result a plume of water vapor may be
seen leaving the exhaust.
