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.)
*Backflow preventer (Recommended for freezing weather conditions:
36 °F (2 °C) and below).
**Vertical condensation drain must be installed in accordance with
local codes.
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 must be met. Local codes supersede these clearances.
Failure to observe this warning may result in severe personal injury or death.
WARNING
Direct vent sidewall
terminations
that use two separate
penetrations for
the intake and
exhaust, distance the
intake and exhaust
terminations at
least 3 ft (915 mm)
away from each
other, no matter the
orientation.
