8 American Dryer Corp. 112217- 4

A = 10-inches (25.4 cm) B = 12-inches (30.48 cm)

EXAMPLE: Two unrestricted openings measuring 10-inches by 12-inches (25.4 cm by 30.48 cm) are acceptable.

If a closet door is installed: unobstructed air openings are required. The air openings shall be located 3-inches (7.62 cm) from the lower opening (above floor level) and upper opening (below ceiling). The total free area of the air openings in the door shall not be less than 130 inch (838.708 cm2). Louvered doors with equivalent air openings are acceptable.

No other fuel-burning appliance shall be installed in the same closet as the dryer.

Fresh Air Supply Requirements ______

This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the national installation regulations.

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 52 inch 1 inch

(335 cm2) is required for each dryer. (Based on

[6.5 cm2] per 1,000 Btu [252 kcal].)

A = 11-inches (27.94 cm)

B = 11-inches (27.94 cm)

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.

EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings measuring 11-inches by 11-inches (27.94 cm by 27.94 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 burner hi-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.

The design of the flue system shall be such that any condensate formed when operating the appliance from cold shall either be retained and subsequently re-evaporated or discharged.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.

Improperly sized or installed exhaust ductwork can create a potential fire hazard.

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. There should be a minimum 6-inch (15.24 cm) clearance between the back guard and the first bend in the ductwork for ease of servicing. 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. Back draft dampers must be installed in all commonly ducted systems. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

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).

112217- 4 www.adclaundry.com 9

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.

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 for this appliance 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.

Single Dryer Venting

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.

The length of the ductwork from the dryer to the outside exhaust outlet, must not exceed 12 feet (3.66 meters). The

minimum diameter of this ductwork must be at least 8-inches (20.32 cm) even though the dryer exhaust duct connection is smaller. Including tumbler/dryer elbow

connections or elbows used for outside protection from the weather, no more than 4 90° elbows should be used in the exhaust duct run. If more than the equivalent of four 90° elbows are used, the cross-sectional area of the ductwork must be increased.

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 in the direction of airflow. The main duct should be tapered, with the diameter increasing before each individual duct is added. The minimum diameter of the individual ductwork must be at least 8-inches (20.32 cm).

IMPORTANT: No more than four dryers should be connected to one main common duct.

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 12 feet (3.66 meters) or has more than 1 elbow in it.

Grounding

A ground (earth) connection must be provided and installed in accordance with local, state, and national regulations or codes of the country of destination. In the absence of these codes, grounding must conform to applicable requirements of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION, or in Canada, the installation must conform to applicable Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The ground connection may be to a proven earth ground at the location service panel.

For added personal safety, when possible, it is suggested that a separate ground wire (size per local codes) be connected from the ground connection of the dryer to a grounded cold water pipe. Do not ground to a gas pipe or hot water pipe. The grounded cold water pipe must have metal-to-metal connection all the way to the electrical ground. If there are any nonmetallic interruptions, such as, a meter, pump, plastic, rubber, or other insulating connectors, they must be jumped out with a wire (size per local codes) and securely clamped to bare metal at both ends.

IMPORTANT: For personal safety and proper operation, the dryer must be grounded.

Provisions are made for ground connection in each dryer at the electrical service connection area.

Electrical Connections

A wiring diagram is located behind the control panel for connection data.

If local codes permit, power to the dryer can be made by the use of a flexible UL listed power cord/pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel. In both cases, a strain relief must be installed where the wiring enters the dryer.

For CE Models Only

The means for disconnection from the supply must be incorporated into wiring having a minimum contact separation of 3.0 mm in all poles.

Single-Phase (1ø) Wiring Connections / Hookup

The electrical input connections are made into the rear service box located at the upper right area of the dryer. The ground connection is made to the copper lug, also provided in this box. To gain access, the service box cover must be removed.

IMPORTANT: A strain relief must be used where the input wiring enters the oven assembly.

Electrically Heated Models Only

The electrical input connections are made at the rear service box located at the right upper section of the dryer. The ground connection is made to a ground wire also provided in this area. To gain access, remove rear service cover.

The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and sometimes neutral) and ground. Single-phase (1ø) power for the control circuit and for any single-phase (1ø) motors (if present) is done internally to the dryer by the factory at the oven contactor. No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer.

The neutral will only be used on 4-wire service. This is typical for 380-416V, 50 Hz.

CAUTION: The dryer must be grounded. A ground lug has been provided for this purpose.

Input connection wiring must be sized properly to handle the dryer’s current draw. This information is printed on the dryer’s data label.

Gas Information ______________________

It is your responsibility to have all plumbing connections, materials, and workmanship conform to local and state regulations or codes of the country of destination. In the absence of such codes, all plumbing connections, materials, and workmanship must conform to the applicable local requirements. In the USA this is the National Fuel Gas Code ANSI Z223.1-LATEST EDITION, or in Canada, the Canadian Installation Codes CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGAB149.2-M91 (L.P. Gas) or LATEST EDITION.

In Australia, the fuel gas code is AS/NZS5601, local authority, gas, electricity, and any other relevant statutory regulations.

It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of all the appliance Btu being supplied.

12 American Dryer Corp. 112217- 4

IMPORTANT: Failure to comply with these codes or ordinances, and/or the requirements stipulated in this manual, can result in personal injury and improper operation of the dryer.

For ease of service, the individual gas supply line of each dryer must have its own manual shutoff valve.

Failure to isolate or disconnect the dryer from supply as noted can cause irreparable damage to the gas valve, voiding the warranty.

The dryer and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa) for non-CE dryers or 50 mb for CE dryers.

NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure test of the gas supply system at test pressures equal to or less than 1/2 psig (3.5 kPa) for non-CE dryers or 50 mb for CE dryers.

WARNING

Piping / Connections

The dryer is provided with two 3/8” N.P.T. inlet pipe connections (1 for each tumbler) at the rear of the dryer. If a separate feed is provided for each tumbler from the main supply line (header), then a 3/8” (9.52 mm) line connection is sufficient. However, if the top and bottom tumbler connections are connected together, the supply from the header must be increased to a minimum of 1/2-inch (12.7 mm). There should be a minimum 6-inch (15.24 cm) clearance between the back guard and the first bend in the gas piping for ease of servicing. It is recommended that a gas shutoff valve be provided to the gas supply line of each dryer for ease in servicing.

The size of the main gas supply line (header) will vary depending on the distance this line travels from the gas meter or, in the case of L.P. gas, the supply tank, other gasoperated appliances on the same line, etc. 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.

Fire or explosion could result due to failure of isolating or disconnecting the gas supply as noted.

NOTE: Undersized gas piping will result in ignition problems, slow drying, increased use of energy, and can create a safety hazard.

The dryer must be connected to the type of heat/gas indicated on the data label and pressure must be confirmed. If this information does not agree with the type of gas available, do not operate the dryer. Contact the reseller who sold the dryer or contact the manufacturer.

The input ratings shown on the data label are for elevations up to 2,000 feet (610 meters), unless elevation requirements of over 2,000 feet (610 meters) were specified at the time the dryer order was placed with the factory. The adjustment or conversion of dryers in the field for elevations over 2,000 feet (610 meters) is made by changing each burner orifice. If this conversion is necessary, contact the reseller who sold the dryer or contact the manufacturer.

IMPORTANT: If connection to this appliance is made with a flexible hose, it must be suitable for the appliance category in accordance with national installation regulations of the country of destination, and if in doubt the installer must contact the supplier. The manufacturer of this appliance does not recommend the use of flexible gas supply line/hose. An external gas supply shutoff must be provided.

Gas Pressure Adjustment

Disconnect electrical power to the dryer.

IMPORTANT: The following procedures must be performed on both top and bottom tumblers.

To adjust gas valve’s internal regulator, remove the regulator vent cap, turn the screw clockwise to raise pressure and counterclockwise to lower pressure.

Gas (burner) pressures are measured with the burner in operation for all burner adjustment conditions. Therefore once the necessary adjustments have been made, the dryer must be operated in a heating cycle to verify that the pressure is correct. If it is not correct, you must discontinue the power to the unit and make further adjustments. Repeat these steps as many times as necessary to achieve the correct burner pressure. Once the adjustment of the valve is complete, the vent cap must be replaced and sealed with, for example, paint to prevent maladjustment by the user.

WARNING (CE Dryers)

Conversions done improperly can result in a fire or explosion!

Preparation for Operation / Start-Up__

The following items should be checked before attempting to operate the dryer:

• Read all “CAUTION,” “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. In the case of 208 VAC or 230/240 VAC, the supply voltage must match the electric service exactly.

• GAS MODELS – Check to ensure that the dryer is connected to the type of heat/gas indicated on the dryer data label.

• GAS MODELS – 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.

Gas Pressure Testing

For proper operation, the gas pressure must be correct, consistent and maintained at the gas pressure rates shown on page 14. Provisions are made at the gas valve for taking gas pressure readings.

There are two types of devices used to measure gas pressure. They are the spring/mechanical type gauge and the manometer. The use of the spring/mechanical type gauge is not recommended because they are very easily damaged and are not always accurate. The preferred type of gauge is the manometer because it is a simple device to use and is highly accurate. A manometer is simply a glass or transparent plastic tube with a scale graduated in inches or millibars. When it is filled with water and pressure is applied, the water in the tube rises, showing the exact gas pressure.

Gas Pressure Test Procedure

Turn gas cock in gas supply line to “OFF” position. 60 Hz dryers: Install pressure tap and attach manometer

(refer to the illustration on page 15). Turn gas cock to “ON” position. Start the dryer in Heat Mode and wait for ignition. Gas

manifold pressure should be as shown on page 14. If the gas pressure needs to be adjusted, refer to “Gas

Pressure Adjustment” on this page. Once test is complete, turn gas cock to “OFF” position.

Remove manometer. Tighten screw inside the pressure tap or install plug.

Turn gas cock to “ON” position and check for leaks with soap solution with main burner “ON.”

Preoperational Test __________________

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. Installer must instruct the user on how to correctly operate the dryer before leaving.

Turn on electric power to the dryer. Refer to the Operating Instructions for starting your particular

model dryer.

Gas Dryers

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.

A gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the water column pressure is correct and consistent.

NOTE: Water column pressure requirements (measured at the pressure tap of the gas valve body) must be verified.

IMPORTANT: In most cases there is no regulator provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank), or an external regulator must be added to each dryer.

16 American Dryer Corp. 112217- 4

Routine Maintenance _________________

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. If the guidelines in this section are met, the dryer will provide many years of efficient, trouble free, and most importantly, safe operation.

WARNING

Lint from most fabrics is highly combustible. The accumulation of lint can create a potential fire hazard. Keep dryer area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

NOTE: Suggested time intervals shown are for average usage, which is considered 6 to 8 operational (running) hours per day.

IMPORTANT: Dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint buildup.

Suggested Cleaning Schedule After Each Load

Clean the lint screen after each load. A clogged lint screen will cause poor dryer performance. The lint door is located just below the loading door of the dryer. Open the lint door, brush the lint off the lint screen, and remove the lint. Inspect lint screen and replace if torn.

Weekly

Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor area.

WARNING

To avoid the hazard of electrical shock, discontinue electrical supply to the dryer.

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.

18 American Dryer Corp. 112217- 4

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: To remove the lint screen from the dryer, first remove the toe/control panel. Then remove two T-20

screws on the front of the lint screen frame and two
