Multiple Dryer Common Venting, ADH-120 | American Dryer Corp ADH-75

Multiple Dryer (Common) Venting

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 as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main duct at an angle not more than 45º in the direction of airflow. The main duct should be tapered, with the diameter increasing before each individual duct is added. The minimum diameter of the individual ductwork must be at least Dimension A (12-inches [30.48 cm] for the ADH-75; 18-inches [45.72 cm] for the ADH-120; 20-inches [50.8 cm] for the ADH-170).

The illustration on the right shows the minimum cross- sectional area for multiple dryer round or square venting. These figures must be increased if the main duct run from the last dryer to where it exhausts to the outdoors is longer than Dimension B (20 feet [6.096 meters]) or has more than 1 elbow in it.
