Allowances must be made for opening the control door. The optimum opening of load door is 30-inches (76.2 cm) for ADH-75; and 38-1/4” (76.2 cm) for ADH-120 and ADH-170. The maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric dryers the maximum thickness of the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62... -
Page 18: Exhaust Requirements
Exhaust Requirements ________________ Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure, which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limits, or lint chamber hi-limit protector thermostat. -

Dimension B (10-inches [25.4 cm] for ADH-75; 16-inches [40.64 cm] for ADH-120; 20-inches [50.8 cm] for ADH-170). Including tumbler/dryer elbow connections or elbows used for outside protection from the weather, no more than 1 elbow should be used in the exhaust duct run. - Page 20 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.
