  • Page 13: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches (30.48 cm) above the dryer’s outer top; except along the front of the dryer, which may be closed if desired.

  • Page 14: Fresh Air Supply Requirements

    D. FRESH AIR SUPPLY REQUIREMENTS The dryer 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 375 cfm (cubic feet per minute) (11 cmm [cubic meters per minute]) must be supplied to each gas 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, and shutdown of the burner by the airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.

  • Page 16: Single Dryer Venting

    NOTE: As per the National Fuel Gas Code, “Exhaust ducts for type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 26 gauge (0.0195-inches [0.50 mm]) thick.”...
  • Page 17 VERTICAL VENTING When vertical single venting is used, the minimum duct size is 8-inches (20.32 cm), refer to Illus. B below, the ductwork from the dryer to the outside outlet cannot exceed 60 feet (18 meters), refer to Illus. B below. This calculation compensates for the use of a maximum of two (2) elbows.
  • Page 18 MULTIPLE DRYER (COMMON) VENTING HORIZONTAL VENTING If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not more than 45º...
  • Page 19 IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased to an extent. For extended ductwork runs, a professional heating, ventilating, and air-conditioning (HVAC) firm should be consulted for proper venting information. VERTICAL VENTING Illus.

Phase 7 Non-Coin Models 1) Upon completing installation of the replacement microprocessor controller (computer) board, reestablish power to the dryer. 2) Start the drying cycle by pressing any of the preset cycles in letters A-F. 3) Verify that the applicable indicator lights on the microprocessor controller (computer) board are lit.
  • Page 41 2. For Models with Direct Spark Ignition (DSI) Module (Type I) Theory of Operation: Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (6-seconds), the flame sensor detects gas burner flame and signals the DSI module to keep the gas valve open as long as there is a call for heat.
  • Page 42 SECTION IX SENSOR ACTIVATED FIRE EXTINGUISHING (S.A.F.E.) SYSTEM The exclusive Sensor Activated Fire Extinguishing (S.A.F.E.) System will extinguish fires that may start in the drying basket (tumbler). A series of sensors positioned throughout the basket (tumbler) and interfaced with the microprocessor will trigger the S.A.F.E.
  • Page 43 WARNING: If the water in the supply line or water solenoid valve freezes, the S.A.F.E. system will be INOPERATIVE!! IMPORTANT: Appliance is to be connected to the water mains using a new hose set and the old hose set should not be reused. 2.
  • Page 44 OPTIONAL MANUAL BYPASS Provisions are made in the dryer S.A.F.E. system for the installation of an optional manual bypass.
