For
multiple
sidewall exhaust termina
tions
(e.g.
Multi-
Unit Systems), an exhaust termina
tion
must be at least 1
ft.
(305mm) away from another exhaust termina
tion.
An
exhaust termina
tion
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.)
