Maximum length of vent system
10" (25.4 cm) round 55 ft. (16.8 m)
It is recommended that you use round vent
instead of rectangular vent, especially if
elbows are required. If rectangular vent is
required, if should be transitioned to 10"
(25.4 cm) round vent as soon as possible.
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.
