SINGLE DRYER VENTING
IMPORTANT: For exhaust duct runs over 30 feet (9.14 meters) a minimum size of 10-inches (25.4
cm) must be used.
HORIZONTAL VENTING
When horizontal single 8-inch (20.32 cm) venting is used, the ductwork to the outlet cannot exceed 30 feet (9.14
meters), refer to Illus. A below. This calculation of 30 feet (9.14 meters) compensates or allows for the use of
a maximum of only one (1) elbow.

IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased
to an extent. For extended ductwork runs, a professional heating, venting, and air
conditioning (HVAC) firm should be consulted for proper venting information.
