IMPORTANT: For exhaust runs over 10 feet a minimum duct size of 10-inchesmust be used.
HORIZONTAL VENTING
When single 10-inch venting is used, the duct work from the dryer to the outside outlet cannot exceed 30 feet (refer to Illus. A below). This calculation of 30 feet compensates or allows for the use of a maximum of only one (1) elbow.
