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.

Exhaust termination
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 that adjacent wall).
2ft.
Exhaust

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.

Air supply inlet
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.

A: In accordance with local codes
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.

Direct vent termination
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 that
adjacent wall).
