The operation of this dryer may affect the operation of other types of gas dryers, which take their air for safe combustion from the same room. If in doubt, consult the dryer manufacturer(s). The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be removed from the floor area that the dryer is to rest on. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply Requirements section). Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer Enclosure Requirements section). Provisions must be made for adequate clearances for servicing and for operation as noted in this manual (refer to Dryer Enclosure Requirements section). The dryer must be installed with a proper exhaust duct connection to the outside as noted in this manual (refer to Exhaust Requirements section). The dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust Requirements section). IMPORTANT: The dryer should be located where a minimum amount of exhaust ducting will be necessary. The dryer must be installed with adequate clearance for air openings into the combustion chamber. IMPORTANT: The dryer must be installed in a location/ environment, which the ambient temperature remains between 40° F (4.44° C) and 130° F (54.44° C). 6 Maytag Co. 113489 - 3 (W10185535) Dryer Enclosure Requirements _______ A = 20-inches (50.80 cm) B = 22.5-inches (57.15 cm) A The requirement to allow the dryer door to open completely is 33.5-inches (85.1 cm). B A minimum overhead clearance of 12-inches (30.48 cm) is required. C Dryer should be positioned a minimum of 12-inches (30.48 cm) away from the nearest obstruction. 24-inches (60.96 cm) is recommended for ease of installation, maintenance, and service. D 1/16” (1.5875 mm) minimum is required. E Flooring should be level or below dryer cabinet for ease of removing panels during maintenance. F Dryers may be positioned sidewall to sidewall, however a 1/16” (1.5875 mm) minimum allowance must be made for the opening and closing of the control door, along with the removal of panels during maintenance. G 4-inch (10.16 cm) maximum. Fresh Air Supply Requirements _______ When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler, and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch “fluttering” problems may result, as well as premature motor failure from overheating. The dryer must be installed with provisions for adequate combustion and make-up air supply. Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. Fresh air ventilation openings shall not be blocked and/or sealed. As a general rule, an unrestricted air entrance from the outdoors of 224 inch2 (1,445 cm2) is required for each dryer. (Based on 1 inch2 [6.5 cm2] per 1,000 Btu [252 kcal].) EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings measuring 20-inches by 22.5-inches (50.80 cm by 57.15 cm) are acceptable. To compensate for the use of registers or louvers used over the openings, this area must be increased by approximately 33%. Make-up air openings should not be located in an area directly near where exhaust vents exit the building. Allowances must be made for remote or constricting passageways or where dryers are located at high altitudes or predominantly low pressure areas. IMPORTANT: Make-up air must be free of dry cleaning solvent fumes. Make-up air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the motors and other dryer components. NOTE: Component failure due to dry cleaning solvent fumes will void the warranty. 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-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside. It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to all the dryers. ! WARNING ▲ Fire Hazard Use a heavy metal vent. Do not use a plastic vent. Do not use a metal foil vent. Failure to follow these instructions can result in death or fire. 113489 - 3 (W10185535) Maytag Co. 7 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.” The 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. Single or independent dryer venting is recommended. It is suggested that the use of 90° turns be avoided; use 30° and/or 45° bends instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. All ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, overlap the duct being connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork. Single Dryer Venting with Transition Piece IMPORTANT: For extended ductwork runs, the crosssectional 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 HVAC firm should be consulted for proper venting information. IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system. Exhaust back pressure measured by a manometer/ magnehelic in the exhaust duct must be no less than 0 and must not exceed 0.6 in wc (1.48 mb). NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening. A = 20 feet (6.10 meters) B = 10-inches (25.4 cm) The ductwork for this dryer must be suitable for the appliance category in accordance with national installation regulations of the country of destination. Outside Ductwork Protection To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (refer to the diagram). IMPORTANT: Do not use screens, louvers, or caps on the outside opening of the exhaust ductwork. NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening. NOTE 2 Distance should be 2 times the diameter of the duct to the nearest obstruction. 8 Maytag Co. 113489 - 3 (W10185535) Single Dryer Venting without Transition Piece The illustration below shows the minimum cross-sectional area for multiple dryer round or square venting. These figures must be increased if the main duct run from the last dryer to where it exhausts to the outdoors is longer than 20 feet (6.09 meters) or has more than 1 elbow in it.

Specific information regarding supply line size should be determined by the gas supplier. NOTE: Undersized gas supply piping can create a low or inconsistent pressure, which will result in erratic operation of the burner ignition system. 12 Consistent gas pressure is essential at all gas connections. It is recommended that a 3/4-inch (19.05 mm) pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 13.0 in wc (32.34 mb) pressure. The following items should be checked before attempting to operate the dryer: • Read all “WARNING” and “DIRECTION” labels attached to the dryer. • Check incoming supply voltage to be sure that it is the same as indicated on the data label. • Be sure that all gas shutoff valves are in the open position. • Be sure all back panels (guards) and electric box covers are in place. • Be sure the service doors are closed and securely in place. • Be sure the lint door/drawer is securely in place. • Rotate the tumbler (drum) by hand to be sure it moves freely. • Check bolts, nuts, screws, terminals, and fittings for tightness and security. • Check that the vent is connected to the dryer and is exhausted to the outdoors. Maytag Co. 113489 - 3 (W10185535) Preoperational Test ___________________ Shutdown Instructions ________________ All dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. If the dryer is to be shutdown (taken out of service) for a period of time, the following must be performed: Turn on electric power to the dryer. Discontinue power to the dryer either at the external disconnect switch or the circuit breaker. Discontinue the fuel supply: close external gas shutoff valve. Also close two internal gas shutoff valves. Refer to the operating instructions for starting your dryer. Open all shutoff valves. When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air to be purged from the lines. NOTE: During the purging period, check to be sure that all gas shutoff valves are open. Tumbler Coating The tumbler is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and nonflammable mild detergent and tumbling them in the tumbler to remove this coating. Microprocessor Programs/Selections Each microprocessor controller (computer) has been preprogrammed by the factory with the most commonly used parameter (program) selections. If computer program changes are required, refer to the computer programming manual, which was shipped with the dryer. Operating Instructions ________________ The dryer is available for use when the appropriate side of the microprocessor display reads “0 minutes” and the amount needed to start the dryer (i.e., “25”). Once the load has been put into the dryer and the main door is closed, start the dryer as follows: • Insert the proper number of coins into the coin acceptor. Once the correct “Amount To Start” has been inserted, the display will read “SELECT CYCLE”. • Determine fabric setting (selection). Once the fabric temperature setting (selection) has been determined, start the dryer by pressing the fabric setting key. • The dryer will now start, and the display will read the setting and the time vended. • The cycle time will count down until the drying and cooling cycles are completed. • Upon completion of the drying and cooling cycles, the dryer will shut off. The dryer tumbler can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired setting. NOTE: When a cycle is interrupted by opening the main door, cycle time will continue to count downward, regardless if the door is open or closed. Service/Parts Information ____________ Service Service must be performed by a qualified trained technician, service agency, or gas supplier. If service is required, contact the Maytag distributor from whom the equipment was purchased. If the distributor cannot be contacted or is unknown, contact the Maytag Co. for a distributor in your area. NOTE: When contacting the Maytag Co., be sure to give them the correct model number and serial number so that your inquiry is handled in an expeditious manner. Parts Replacement parts should be purchased from the distributor from whom the Maytag equipment was purchased. If the distributor cannot be contacted or is unknown, contact the Maytag Co. for a distributor in your area. NOTE: When ordering replacement parts from the Maytag distributor or the Maytag Co. be sure to give them the correct model number and serial number so that your parts order can be processed in an expeditious manner. Routine Maintenance _________________ A program should be established for the inspection and cleaning of lint in the burner area, exhaust ductwork, and area around the back of the dryer. The frequency of inspection and cleaning can best be determined from experience at each location. Exhaust duct outlet should be checked periodically for blockages, and if any found, removed. Cleaning A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper airflow. The accumulation of lint can restrict this airflow. NOTE: Suggested time intervals shown are for average usage, which is considered 6 to 8 operational (running) hours per day. Every 6 months, inspect the exhaust ducting and remove any lint buildup. Selection (setting) changes can be made at any time during the drying cycle. 113489 - 3 (W10185535) Maytag Co. 13 Suggested Cleaning Schedule ! WARNING ▲ Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. Adjustments 7 Days After Installation and Every 12 Months Thereafter Inspect bolts, nuts, screws, setscrews, grounding connections and nonpermanent gas connections (unions, shutoff valves, and orifices). Belts should be examined. Cracked or seriously frayed belts should be replaced. Complete an operational check of controls and valves. Complete an operational check of all safety devices (lint door/ drawer switch, door switches, sail switch, and hi-limit thermostats). Data Label Information ________________ Standard Label Every Third or Fourth Load Clean the lint screen every third or fourth load. A clogged lint screen will cause poor dryer performance. The lint door/ drawer is located just below the loading door of the dryer. Open the lint door/drawer, brush the lint off the lint screen, and remove the lint. Inspect lint screen and replace if torn. NOTE: To remove the lint drawer from the dryer first pull the screen out roughly half way and lift the clip on the lower left side of the lint drawer up. Now you will be able to pull the lint drawer completely out. IMPORTANT: The frequency of cleaning the lint screen can best be determined from experience at each location. Weekly Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor area. 90 Days Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment. Clean any lint accumulation in and around the motor(s) casing opening. NOTE: To prevent damage, avoid cleaning and/or touching ignitor/flame-probe assembly. Every 6 Months Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal exhaust ducting. NOTE: Do not obstruct the flow of combustion and ventilation air. Check back draft dampers in the exhaust ductwork. Inspect and remove any lint accumulation, which can cause the damper to bind or stick. A back draft damper that is sticking partially closed can result in slow drying and shutdown of heat circuit safety switches or thermostats. When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the cleaning of appliances is recommended.
