SINGLE DRYER VENTING
IMPORTANT: For exhaust duct runs over 40 feet (12.19 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 40 feet
(12.19 meters), refer to Illus. A below. This calculation of 40 feet (12.19 meters) compensates or allows for the
use of a maximum of only one (1) elbow (which is the outside outlet protection).
Illus. A
If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross section
area of the ductwork must be increased in proportion to the number of elbows or duct run added.
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.
