Multiple Dryer Common Venting | American Dryer Corp MD-170PTVW

4. Multiple Dryer (Common) Venting

IMPORTANT: For extended ductwork runs, the cross-sectional 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 heating, ventilating, and air-conditioning (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.

IMPORTANT: No more than 4 dryers for the MDG-120 and only 3 for the MD-170 should be connected to 1 main common duct.

The illustration below 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 12 feet (3.656 meters) or has more than 1 elbow in it.

A = MDG-120 14-inch (35.56 cm)

MDG-170 18-inch (45.72 cm)

MDS-170 20-inch (50.8 cm)

B = 20 feet (6.10 meters)

NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening.

NOTE 2 Distance should be 2 times the diameter of the duct to the nearest obstruction.
