-Clearances for sidewall terminaons-
Multiple Sidewall Terminations
An exhaust termination must be at least
1 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.)
Multiple DV Sidewall Terminations
A direct vent (DV) termination must be
at least 1 ft (305 mm) away from other
direct vent terminations.
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
adjacent wall.)

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.
Improper installation can result in carbon monoxide poisoning or death. 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.
