Maximum length of vent
system
For best performance, use no more
than three 90° elbows. If more than
one elbow is used, make sure that
there is a minimum of 24 inches
(61 cm) of straight vent between
any two elbows. Do not install two
elbows together.
It is recommended that you use
round vent instead of rectangular
vent, especially if elbows are
required. If rectangular vent is
required, it should be transitioned
to 10" (25.4 cm) round vent as
soon as possible.

To calculate the length of system
you need, add the equivalent feet
for each duct piece that will be
needed. See example for 10"
(25.4 cm) round vent system.
NOTE:The exterior-mounted vent
motor requires a separate wiring
cable that should be installed at
the same time the vent work is
installed.
