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.

<Case 1>
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.

-For sidewall terminations-
For multiple sidewall exhaust terminations (e.g. Multi-Unit
Systems), an exhaust termination must be at least 305mm
610 mm
(1 ft.) away from another exhaust termination. An exhaust
(2 ft.)
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.)
Inside
corner
For multiple-unit, direct-vent sidewall terminations that
combine the intake and exhaust into a single penetration,
610 mm
space each direct-vent termination at least 915 mm (3 ft.)
(2 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.)
