  • Page 12: Dryer Enclosure Requirements

    6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual (refer to Dryer Enclosure Requirements in Section C). 7. Dryer must be exhausted to the outdoors in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust Requirements in Section E).

  • Page 13: Fresh Air Supply Requirements

    NOTE: Air considerations are important for proper and efficient operation. 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 air is necessary for each dryer. An airflow of 400 cfm (cubic feet per minute) (11.3 cmm [cubic meters per minutes]) must be supplied to each gas dryer.

  • Page 14: 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 shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-limit thermostats. (Refer to the illustrations on page 11 and page 12 for details.) The dryer must be installed with a proper exhaust duct connection to the outside.

  • Page 15: Single Dryer Venting

    SINGLE DRYER VENTING IMPORTANT: A minimum exhaust duct size of 6-inches (15.24 cm) must be used. For a 6-inch (15.24 cm) horizontal run where a maximum of one (1) elbow is used (refer to the illustration below), the ductwork from the dryer outlet must not exceed 8 feet (2.44 meters). If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross-sectional area of the ductwork must be increased in proportion to the number of elbows or duct run added.
  • Page 16 SINGLE DRYER VENTING IMPORTANT: A minimum exhaust duct size of 8-inches (20.32 cm) must be used. For an 8-inch (20.32 cm) horizontal run where a maximum of one (1) elbow is used (refer to the illustration below), the ductwork from the dryer outlet must not exceed 40 feet (12.2 meters). If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross-sectional area of the ductwork must be increased in proportion to the number of elbows or duct run added.
  • Page 17 When single 8-inch (20.32 cm) vertical venting is used (refer to the illustration below), the ductwork from the dryer to the outside outlet cannot exceed 35 feet (10.67 meters) in total length. This calculation of 35 feet (10.67 meters) compensates or allows for the use of a maximum of three (3) elbows including the 180º (turned downward) outside outlet.
  • Page 18 American Dryer Corp. 113222 - 5...
  • Page 19 IMPORTANT: For extended ductwork runs, the cross section 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.
