-For sidewall terminaons-
For multiple sidewall exhaust terminations (e.g. Multi-
Unit Systems), 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-unit, 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.)

Installaon Manual
For direct-vent sidewall
terminations that use two
separate penetrations for
the intake and exhaust,
keep the termination
clearances shown in the
diagrams on the right.
Please follow all local and national codes in regards to proper termination
clearances. In the absence of such codes, the clearances below can be used as
guidelines. Local codes supersede these guidelines.
