  • Page 13: Dryer Enclosure Requirements

    8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust Requirements in Section E). IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary. 9.

  • Page 14: Fresh Air Supply Requirements

    D. FRESH AIR SUPPLY REQUIREMENTS Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An unrestricted source of 800 cfm (22.65 cmm) is necessary for each dryer. An unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required for each dryer.

  • Page 15: Exhaust Requirements

    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) hi-heat thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.
  • Page 16 2. Single Dryer Venting Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible.

  • Page 18 Maytag 113203-3...
  • Page 19 3. Multiple Dryer (Common) Venting 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...
  • Page 20 To 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 twice the diameter of the duct between the duct opening and nearest obstruction.
