B. LOCATION REQUIREMENTS Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing). 1.
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 dryers outer top; except along the front of the dryer which may be closed if desired. NOTE: Allowances must be made for opening the control door. X = 12-inch (30.48 cm) minimum, 24-inches (60.96 cm) is suggested for ease of maintenance. NOTE: Air considerations are important for proper and efficient operation.
D. FRESH AIR SUPPLY REQUIREMENTS The air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, 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. If registers or louvers are installed over the openings, then the area must be increased.
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-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.
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 0.0195-inches (26 gauge [0.05 mm]) thick. SINGLE DRYER VENTING IMPORTANT: For exhaust duct runs over 30 feet (9.14 meters) a minimum size of 10-inches (25.4 cm) must be used. HORIZONTAL VENTING When horizontal single 8-inch (20.
VERTICAL VENTING When vertical single venting is used the minimum duct size is 10-inches (25.4 cm) refer to Illus. B below, the ductwork from the dryer to the outside outlet cannot exceed 60 feet (18.3 meters) refer to Illus. B below. This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180° (turned downward) outside outlet. Illus.
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 45° in the direction of the airflow. No more than four (4) dryers should be connected to one (1) main common duct run.
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. D MULTIPLE DRYER VENTING (VERTICAL) The maximum length of venting from the last dryer to where it exhausts: Vertical venting must not exceed 25 feet (7.
IMPORTANT VENTING REMINDERS 1. Ductwork size and installation should be done by a qualified professional. 2. The dryer must be exhausted to the outdoors. 3. Ductwork should be routed as short as possible to the outdoors with as few elbows as possible. 4. Avoid 90° turns, use 30° or 45° turns instead. 5. The size of the ductwork must be a minimum of 10-inches (25.4 cm) if vented vertically and 8-inches (20.32 cm) if vented horizontally. 6.

(Refer to the illustration below.
2. For Models with Johnson Direct Spark Ignition (DSI) Controller (G760) 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. The DSI module will LOCK OUT if the gas burner flame is not sensed at the end of the trial for ignition period.
SECTION IX MANUAL RESET BURNER HI-LIMIT INSTRUCTIONS A. PHASE 7 This dryer was manufactured with a manual reset burner hi-limit thermostat, which is monitored by the Phase 7 computer. If the burner hi-limit is open prior to the start of the drying cycle, the dryer will start momentarily and then shut down, the Phase 7 computer will display BURNER HIGH LIMIT FAULT with an audio indication.
