-For sidewall terminations-
-For rooftop terminations-
For multiple sidewall exhaust terminations (e.g. multi-unit
systems), an exhaust termination must be at least 305mm
(1 ft.) away from another exhaust termination. An exhaust
termination must also be at least 610 mm (2 ft.) away
from an inside corner. (if the adjacent wall is less than 610
mm (2 ft.) 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 305 mm (1 ft.)
away from each other, no matter the orientation. A direct-
vent termination must also be at least 610 mm (2 ft.) away
from an inside corner. (if the adjacent wall is less than 610
mm (2 ft.) of length, the minimum required distance away
from the inside corner will be equal to the length of that
adjacent wall.)
For multiple-unit rooftop terminations (whether for standard 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 610 mm (2 ft.) away from a wall or surface.
Exhaust and/or
direct-vent sidewall
terminations should
be at least 610 mm
(2 ft.) away from an
opposite surface/
wall. Do not place the
termination directly
in front of an opening
into a building .

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