Installaon Manual
For multiple sidewall exhaust 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.)

For multiple, direct-vent sidewall terminations that
combine the intake and exhaust into a single penetration,
space each direct-vent termination at least 1 ft. (305 mm)
away from each other, no matter the orientation. 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.)
