Clearances for sidewall terminations-
Multiple Sidewall Terminations
An exhaust termination must be at least 1 ft (305mm) away
from another exhaust termination. An exhaust termination
must also be at least 2 ft (610 mm) away from an inside
corner. (If the adjacent wall is less than 2 ft (610 mm) of
length, the minimum required distance away from the inside
corner will be equal to the length of that adjacent wall.)
Multiple DV Sidewall Terminations
A direct vent (DV) termination must be at least 1 ft (305 mm)
away from other direct vent terminations.
A direct vent termination must also be at least 2 ft (610 mm)
away from an inside corner. (If the adjacent wall is less than
2 ft (610 mm) of length, the minimum required distance
away from the inside corner will be equal to the length of
that adjacent wall.)
Improper installation can result in carbon monoxide poisoning or death. Follow all local
and national codes in regards to proper termination clearances. In the absence of such
codes, the clearances below must be met. Local codes supersede these clearances.
Failure to observe this warning may result in severe personal injury or death.
WARNING
Exhaust and/or direct vent sidewall terminations
should be at least 2 ft (610 mm) away from
an opposite surface/wall. Do not place the
termination directly in front of an opening into
a building
.
