For direct-vent sidewall

keep the termination
clearances shown in the

-For sidewall terminations-
For multiple sidewall exhaust terminations (e.g. Multi-
2 ft.
Unit Systems), an exhaust termination must be at least 1
(610 mm) min
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,
(610 mm) min
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
