12 E. 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 , overheating of the dryer , and shut down of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) [...]

13 NOTE: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) water column (W .C.). It is suggested that the ductwork from each dryer not exceed the limitations noted in this manual. If the ductwork exceeds these limitations or has numerous elbows, the cross-sec[...]

16 3. Multiple Dryer (Common) V enting 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 tapere[...]

17 T o protect the outside end of the horizontal ductwork from the weather , a 90º elbow bent downward should be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the roof, it should be protected from the weather by using a 180º turn to point the opening downward. In either case, allow at least [...]
