ADDITIONAL CLEARANCES
Please follow all local and national codes in regards to proper termination clearances. In the absence of
such codes, the following clearances can be used as guidelines. Local codes supersede these
guidelines.

For multiple sidewall exhaust
terminations (e.g. multi-unit
systems), an exhaust termination
must be at least 1 ft. away from
another exhaust termination. An
exhaust termination must also be
at least 2 ft. away from an inside
corner (if the adjacent wall is less
than 2 ft. of length, the minimum
required distance away from the
inside corner will be equal to the
length of the wall). For Direct-Vent sidewall
terminations that use two
separate penetrations for the
intake and exhaust, distance
the intake and exhaust
terminations at least 3 ft. away
from each other, no matter the
orientation.
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. away from
each other, no matter the
orientation. A direct-vent
termination must also be at least 2
ft. away from an inside corner (if the
adjacent wall is less than 2 ft. of
length, the minimum required
distance away from the inside
corner will be equal to the length of
the wall).

For multiple-unit rooftop terminations (whether for standard indoor or Direct-
Vent installations) space all exhaust and intake terminations in accordance
with local codes. An exhaust termination must be spaced from a wall or
surface in accordance with local codes as well. In the absence of such a
code, an exhaust termination must be a horizontal distance of at least 2 ft.
away from a wall or surface.
Exhaust and/or Direct-Vent
sidewall terminations should
be at least 2 ft. away from an
opposite surface/wall. Do not
place the termination directly
in front of an opening into a
building.
