VERTICAL VENTING
When vertical single 8-inch (20.32 cm) venting is used (refer to Illus. B below), the ductwork from the dryer to
the outside outlet
cannot exceed 55 feet (16.7 meters). 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 ductwork run or quantity of elbows used exceeds the above noted specifications, the
cross-sectional 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 must be consulted for proper venting information.
