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.
Illus. A
VERTICAL VENTING
When vertical single venting is used the minimum duct size is 10-inches (25.4 cm) refer to Illus. B below, the
ductwork from the dryer to the outside outlet cannot exceed 60 feet (18.3 meters) refer to Illus. B below. This
calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the
180° (turned downward) outside outlet.
Illus. B
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, ventilating, and
air-conditioning (HVAC) firm should be consulted for proper venting information.
