For sidewall terminations
Please follow all local and national codes in regards to proper termination clear-
ances. In the absence of such codes, the clearances below 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.
(305mm) away from another exhaust termination. An ex-
haust termination must also be at least 2 ft. (610mm) away
from an inside corner. (If the adjacent wall is less than 2 ft.
(610mm) 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 1 ft. (305mm)
away from each other, no matter the orientation. A direct
vent termination must also be at least 2 ft. (610mm) away
from an inside corner. (If the adjacent wall is less than 2 ft.
(610mm) of length, the minimum required distance away
from the inside corner will be equal to the length of that
adjacent wall.)
For direct-vent sidewall
terminations that use
two separate pene-
trations for the intake
and exhaust, keep the
termination clearances
shown in the diagrams
on the right.
