SINGLE DRYER VENTING
IMPORTANT: A minimum exhaust duct size of 8-inches (20.32 cm) must be used.
For an 8-inch (20.32 cm) horizontal run where a maximum of one (1) elbow is used (refer to the illustration below), the ductwork from the dryer outlet must not exceed 40 feet (12.2 meters).
If the length of the duct run or quantity cross-sectional area of the ductwork must be
of elbows used exceeds the above noted specifications, the increased in proportion to the number of elbows or duct run added.
IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits noted in this manual, a professional heating, ventilating, and air-conditioning (HVAC) firm should be consulted for proper venting information.
When single 8-inch (20.32 cm) venting is used, for a horizontal run, the ductwork from the dryer to the outside outlet cannot exceed 40 feet (12.2 meters) in total length. This calculation of 40 feet (12.2 meters) compensates or allows for the use of a maximum of one (1) elbow (which is the outside outlet protection). Refer to the illustration above.
