Vent outlet is located at the center of the bottom dryer back. The vent can be routed up, down, left, right, behind the dryer or straight out the back of the dryer. Multiple Dryer Venting [] A main vent can be used for venting a group of dryers. Main vent should be sized to remove 200 CFM of air per dryer. Large-capacity lint screens of proper design may be used in the main vent if checked and cleaned frequently. The room where the dryers are located should have make-up air equal to or greater than the CFM of all the dryers in the room. [] Back-draft Damper Kit, Part No. 3391910, is available from your Whirlpool dealer and should be installed in each dryer's vent to prevent exhausted air from returning into the dryers and to keep the exhaust in balance within the main vent. Unobstructed air openings are required. Each vent should enter the main vent at an angle pointing in the direction of the airflow. Vents entering from the opposite side should be staggered to reduce the exhausted air from interfering with the other vents. The maximum angle of each vent entering the main vent should be no more than 30 ° . A_ Vent System Length Maximum length of vent system depends upon the type of vent used, number of elbows and type of exhaust hood. The maximum length for both rigid and flexible vent is shown in the chart.

If dryer is installed in a confined area, such as a bedroom, bathroom or closet, provision must be made for enough air for combustion and ventilation. (Check governing codes and ordinances.) See "Recessed Area and Closet Installation Instructions" in the "Location Requiements" section. A 4" (10.2 cm) outlet hood is preferred. However, a 21/2'' (6.4 cm) outlet exhaust hood may be used. A 21A'' (6.4 cm) outlet creates greater back pressure than other hood types. For permanent installation, a stationary vent system is required. air flow _ B _._-- A. Individualdryervent B. Mainvent Keep air openings free of dry cleaning fluid fumes. Fumes create acids which, when drawn through the dryer heating units, can damage dryers and loads being dried. A clean-out cover should be located on the main vent for periodic cleaning of the vent system. If an exhaust hood cannot be used: The outside end of the main vent should have a sweep elbow directed downward. If the main vent travels vertically through the roof, rather than through the wall, install a 180° sweep elbow on the end of the vent at least 2 ft. (61 cm) above the highest part of the building. The opening wall or roof shall have a diameter 1/2" (1.3 cm) larger than the vent diameter. The vent should be centered in the opening. B A C ,,¢ jf A. Exhausthood or elbow BC.
