Dryer Enclosure Requirements _______

Commercial Type II

Bulkheads and partitions should be made of noncombustible material.

NOTE: Allowances must be made for opening the control door.

A The requirement to allow the load door to open completely

is 38-inches (96.5 cm).

B A minimum overhead clearance of 12-inches (30.48 cm) is

required. 18-inches (45.72 cm) is recommended.

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 2-inches (5.08 cm) minimum is required. E Flooring in front of the dryer must be lower than the dryer

cabinet to allow the lint door to open. 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 lint door, along with the

removal of panels during maintenance. G Dryer must protrude 1-inch (2.54 cm) from the surface of

any bulkhead or partition around the dryer to allow the

control door to open. H The minimum clearance from the top of the dryer to the

10 American Dryer Corp. WFR 113546-11

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. As a general rule, an unrestricted air entrance from the outdoors of 250

(1,612.9 cm2) is required.

inch 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 makeup air is distributed equally to all the dryers.

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.

NOTE: Component failure due to dry cleaning solvent fumes will void the warranty.

A = 22-3/8” (56.8 cm) B = 22-3/8” (56.8 cm)

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.

The dryer shall not be exhausted into any gas vent, chimney, wall, ceiling or concealed space of a building.

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 minimized; 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. (This dryer comes equipped with a back draft damper installed.) Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

IMPORTANT: Exhaust back pressure measured by a manometer/magnehelic in the exhaust duct must be no less than 0 and must not exceed 0.7 in WC (1.7 mb).

NOTE: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system except where necessary to maintain exhaust back pressure (in the exhaust duct) between zero and 0.7 inch water column. Where employed, booster fans must not activate the dryer airflow proving switch (sail switch) when the dryer is not in operation.

EXAMPLE: For a bank of four dryers, two unrestricted openings measuring 22-3/8” by 22-3/8” (56.8 cm by 56.8 cm) are acceptable. With louvers, two openings measuring 25.8” x 25.8” (65.5 cm x 65.5 cm) are acceptable.

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.

WFR113546-11 www.adclaundry.com 11

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: The MINIMUM duct size for a unit with gas or electric heat is 10-inches (25.4 cm) for a round duct and 9-inches x 9-inches (22.86 cm x 22.86 cm) for a square duct. For a unit with steam heat the minimum recommended duct size is 12-inches (30.48 cm) for a round duct and 10.6-inches x 10.6-inches (26.92 cm x 26.92 cm) for a square duct. The duct size must not be reduced anywhere downstream of the dryer.

Exhaust Transition Piece (Gas and Electric)

Dryers with gas and electric heat are equipped with a 12-inch to 10-inch exhaust transition piece installed, for use with 10-inch ducting. If the exhaust duct size needs to be increased to 12-inch dia (or greater) this 12-10 transition should be removed.

Horizontal Single Dryer Venting

For a horizontal run the total length of ductwork from the dryer outlet must not exceed dimension “A” in the following illustration.

HORIZONTAL SINGLE DRYER VENTING

NOTE 1: When passing through combustible material 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.

For a vertical run with three 90° elbows, the ductwork from the dryer to the outside outlet cannot exceed dimension “B” in the following illustration.

VERTICAL SINGLE DRYER VENTING

Combined Vertical and Horizontal Single Dryer Venting

For a combined vertical and horizontal run, the dryer to the outside outlet cannot exceed the sum of dimensions “A” and “B” in the following illustration.

This calculation of “A” and “B” allows for the use of a maximum of 3 elbows including one elbow which is the outside outlet protection. Refer to the illustration below.

NOTE 1: When passing through combustible material 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.

If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross-sectional area of the ductwork may need to be increased.

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 noted in this manual, a professional HVAC firm should be consulted for proper venting information.

NOTE 1: When passing through combustible material 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.

NOTE 2: “A” dimension + “B” dimension should not exceed 20 feet (6.1 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 may need to 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 diameter of the common main duct should increase before each individual duct is added (refer to figures on

page 14 and page 15).

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 propane 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.

Installer within Australia – refer to AS/NZS5601.1 for guidance on gas supply pipe sizing required for this appliance installation.

NOTE: Undersized gas supply piping can create a low or inconsistent pressure, which will result in erratic operation of the burner ignition system.

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.

A plugged tap, accessible for a pressure gauge connection, must be installed in the main gas supply line immediately upstream of the dryers.

IMPORTANT: Pipe joint compounds that resist the action of natural, propane, and butane gases must be used.

Test all connections for leaks by brushing on a soapy water solution (liquid detergent works well).

WARNING

Never test for leaks with a flame!!!

Converting from One Family of Gas to Another ______________________

WARNING (CE Dryers)

This appliance must only be operated with the gas type indicated on the dryer’s rating plate. If the appliance is converted (gas type changed), a new rating plate must be obtained from ADC (dryer’s serial number is required to purchase a conversion kit).

IMPORTANT: Any burner changes or conversions must be

made by a qualified professional. The dryers manufactured for Belgium, Luxemburg, Greece,

Estonia, Slovak Republic, Iceland, Malta, Poland and Cyprus cannot be converted from one family of gas to another.

Conversion from Natural Gas to Propane or Butane Gas

The following conversion allows the dryer to be operated with either propane, butane, or other liquefied petroleum gases. The use of gas valve conversion kit (P/N 140419) disables the internal regulator of the gas valve. Therefore, the gas supply is ungoverned and an external regulator must be provided at the source of the supply (example propane tank) or the gas supply line to the dryer. The type of conversion kit supplied will depend on the country the dryer is installed in.

Gas Pressure Adjustment

IMPORTANT: When converting from one gas to another with regulated gas conversion kit, the following procedures must be performed.

Disconnect electrical power to the dryer. To adjust gas valve’s internal regulator, remove the regulator

vent cap (figure 5). Turn the plastic adjustment screw in the valve. 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. Refer to “Gas Pressure Test Procedure” for instructions on this procedure. 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. Operate the dryer through one complete cycle to ensure proper operation.

WARNING

This appliance must only be operated with the gas type indicated on the dryer’s rating plate. If the appliance is converted (gas type changed), a new rating plate must be obtained from American Dryer Corporation (dryer’s serial number is required to purchase a conversion kit).

Gas Pressure Testing

For proper operation, the gas pressure must be correct, consistent and maintained at the gas pressure rates shown

page 21. Provisions are made at the gas valve for taking

on 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. CE Dryers: Back out miniature screw inside pressure tap and

attach manometer. Refer to figure 5 on Non-CE Dryers: Install pressure tap and attach manometer.

Refer to figure 5 on Turn gas cock to “ON” position. Start the dryer in Heat Mode and wait for ignition. Gas manifold

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

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

Remove manometer. Tighten screw inside the pressure tap (50 Hz dryers) or reinstall plug (60 Hz dryers).

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

Steam Information ____________________

It is your responsibility to have all plumbing connections made by a qualified professional to ensure that the steam plumbing installation is adequate and conforms with local, state, and country regulations or codes.

Care must be exercised when leveling steam dryers into final position. This will promote good steam coil drainage. Return line should be level or pitched down slightly for good drainage. Absence of these conditions will result in probable water hammer and premature heat exchanger fracture and leakage.

The presence of condensate in the steam will cause water hammer and subsequent heat exchanger failure. The steam supply connection must be taken from the top of a well-dripped steam main. If the supply run-out to the dryer exceeds 25 feet (7.6 meters), it should be dripped just before the control valve with a proper trap and dirt pocket.

IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in component failure, which will void the warranty.

Steam Coil pH Level

The normal pH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For steel type steam coils the pH level must be maintained between a value of 9.5 to 10.5. These limits are set to limit the acid attack of the steam coils.

IMPORTANT: Coil failure due to improper pH level will void the warranty.

Installation Instructions

To ensure an adequate supply of steam is provided, be sure that the steam supply line and steam return line are sized and laid out as stipulated in this manual. Inadequate steam supply line and steam return line or improper steam plumbing will result in poor performance and can cause component failure. Clean, dry steam must be provided to the dryer.

IMPORTANT: Steam coil failure due to water hammer by wet steam will void the warranty.

The presence of condensate in the steam supply line will cause water hammer and subsequent heat exchanger (steam coil) failure. The steam supply connection into the main supply line must be made with a minimum 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the dryer.

The steam supply line to the dryer must include a 12-inch (30.48 cm) riser along with a drip trap and check valve. This will prevent any condensate from entering the steam coil.

Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the steam coil connections to crack if they are hard piped to the supply and return mains.

0.86 MPa

80.74 kg/hr

Shutoff valves for each dryer should be installed in the supply line, return line, and drip trap return line. This will allow the dryer to be isolated from the supply main and the return main if the dryer needs maintenance work.

Install an inverted bucket steam trap and check valve at least 12-inches (30.48 cm) below the steam coil as close to the coil as possible. A trap with a minimum capacity of 356 lb (162 kg) of condensate per hour at 125 psi (0.86 MPa) is needed for each unit. (Based on 2 times the steam consumption per hour.)

Install a 3/4-inch vacuum breaker at the steam coil (as shown) to prevent coil damage from acids that can form in a vacuum. Mount steam solenoid valve in orientation shown, with coil up. The supply line should be supported to prevent damage to the steam coil due to the overhung weight of the steam solenoid valve.

The supply line and the return line should be insulated. This will save energy and provide for the safety of the operator and maintenance personnel.

Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly causing steam coil damage. All horizontal runs of steam supply piping should be pitched 1/4-inch (6.35 mm) for every 1 foot (0.31 meters) back towards the steam supply header causing the condensate in the line to drain to the header. Install a bypass trap in any low point to eliminate wet steam.

IMPORTANT: Flexible hoses/couplings must be used. Coil failure due to hard plumbing connections will void the warranty.

Steam Solenoid Valve Connections

In standard format, this dryer is shipped with a 24VAC steam solenoid valve for installation in the steam supply piping (refer to steam piping diagram). This valve is stored in the dryer’s lint compartment during shipment. Wiring and quick connections for this valve are provided in the rear of the dryer (top right when viewed from rear).

Water Information_____________________

(For Optional Fire Suppression System) Before You Start Check Local Codes and Permits

Call your local water company or the proper municipal authority for information regarding local codes.

IMPORTANT: It is your responsibility to have all plumbing connections made by a qualified professional to ensure that the plumbing installation is adequate and conforms to local, state, and federal regulations or codes.

It is the installer’s or owner’s responsibility to see that the required water pressure, pipe size, or connections are provided. The manufacturer assumes no responsibility if the fire suppression system is not connected, installed, or maintained properly.

The water connection for the manual bypass is made to the “tee” or “three way” fitting, which has a 3/8” F.N.P.T. and a coupling must be used to provide the minimum 1/2-inch (12.7 mm) supply (feed) line.

Electrical Requirements

No independent external power source or supply connection is necessary. The 24-volt power to operate the fire suppression system is accomplished internally in the dryer (from the dryer controls).

WARNING

Electrical power must be provided to the dryer at all times. If the main electrical power supply to the dryer is disconnected, the fire suppression system is inoperative!!

Installation Water Supply

The fire suppression system must be supplied with a minimum water pipe size of 1/2-inch (12.7 mm) and be provided with 40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure.

If the rear area of the dryer or the water supply is located in an area where it will be exposed to cold/freezing temperatures, provisions must be made to protect these water lines from freezing.

WARNING

If the water in the supply line or water solenoid valve freezes, the fire suppression system will be inoperative!!

Water Connections

The water connection is made to a 3/4”-11.5 NH hose or 3/4” B.S.P. adaptor, depending on the destination country. A flexible supply line/coupling must be used in an effort to avoid damaging the electric water solenoid valve.

NOTE: The 3/4”-11.5 NH is a standard hose coupling screw thread. It is not to be confused with 3/4” N.P.T., or 3/4 B.S.P. The sealing of an NH connection is made with a washer as opposed to the mating threads of an N.P.T. or B.S.P. assembly. The 3 thread designs are not compatible.

It is recommended that a filter or strainer be installed in the water supply line.

IMPORTANT: Flexible supply line/coupling must be used. Solenoid valve failure due to hard plumbing connections will void warranty.

The dryer is to be connected to the water mains using a new hose set and the old hose set should not be reused.

Optional Manual Bypass

Provisions are made in the dryer’s fire suppression system for the installation of an optional manual bypass. The connections for the manual bypass are made at the “tee” or “three way” fitting located in the outlet supply side of the water solenoid valve. The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it is easily accessible. The use and connection of this manual bypass is at the option or discretion of the owner.

WARNING

ELECTRICAL SHOCK HAZARD

Electrical shock hazard can result in serious injury.

If the water dispensing system is activated do not attempt to operate the dryer.

If the water dispensing system is activated have the dryer inspected by a qualified agency before operating the dryer.

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 rating plate. In the case of 208 VAC or 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 rating plate.

• 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.

26 American Dryer Corp. WFR 113546-11

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. If, for any reason, the appliance cannot be adjusted to perform correctly, or if any other concerns are detected, contact your local service organization or dealer. 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.

NOTES ______________________________________________________

_____________________________________________________________

Gas Models

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 a propane dryer. The water column pressure must be regulated at the source (propane tank), or an external regulator must be added to each dryer.

Steam Models

Check to ensure all steam shutoff valves are open.

Safety Related Circuits

Make a complete operational check of all safety related circuits:

• Door Switch(es)

• Hi-Limit Thermostats

• Sail Switch Make a complete operational check of all operating controls.

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.

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.

Suggested Cleaning Schedule Every Third of Fourth Load

Clean the dryer’s internal lint screen about every third or fourth load. A clogged lint screen will reduce the airflow, and cause poor dryer performance. The screen is located behind the lint door just below the main loading door. Open the lint door and brush the lint off the screen.

Inspect the lint screen and replace if torn.

NOTE: To remove the lint screens from the dryer, open the lint door. Located just above the lint screen is a clamp retained by six screws (refer to figure 6). Use a 5/16” (8 mm) wrench to remove the six screws and the clamp. The lint screens are mounted in a track. Slide the lint screens out of the track.

To replace them, reverse the above procedure.

IMPORTANT: No replacements, credits, or refunds will be issued if the claim cannot be processed due to insufficient information. The party filing the claim will be notified in writing, either by “FAX” or “CERTIFIED MAIL – Return Receipt Requested,” as to the information necessary to process claim. If a reply is not received by the Warranty Department within 30 days from the FAX/letter date, then no replacements, credits, or refunds will be issued, and the merchandise will be discarded.

Routine Maintenance _________________

Cleaning

A program and/or schedule should be established for the 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.

When cleaning the dryer cabinet, avoid using harsh abrasives. A product intended for the cleaning of appliances is recommended.

FIGURE 6

Weekly

Clean lint accumulation from the lint chamber, thermostat and microprocessor temperature sensor area. The thermostat and microprocessor temperature sensor area is located in the ductwork just above the lint screen. All of these areas are accessed by opening the lint door.

Steam Dryers

Clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment.

WARNING

When cleaning steam coil fins, be careful not to bend the fins. If fins are bent, straighten by using a fin comb, which is available from local air-conditioning supply houses.

WFR113546-11 www.adclaundry.com 29

90 Days

Remove lint from the gas valve burner area with a dusting brush or vacuum cleaner. The gas valve burner area is located behind the control door just above the main loading door.

NOTE: To prevent damage, avoid cleaning and/or touching igniter/flame-probe assembly.

Clean any lint accumulation in and around the motor(s) casing openings. The motors are located at the back of the dryer. The dryers back guard must be removed to access this area.

WARNING

To avoid the hazard of electrical shock and contact with moving parts, discontinue electrical supply to the dryer before removing the back guard.

6 Months

Inspect and remove lint accumulation in the dryer's air handling systems. This includes customer furnished make-up air openings, exhaust ductwork systems, and from the dryers internal exhaust ducting.

NOTE: The build up of lint in the air handling systems can create a potential fire hazard. It can also reduce the flow of combustion, exhaust and ventilation gases, reducing dryer performance.

Cleaning of the dryer's internal exhaust may require removing the lint screen. See the instructions above for removing the lint screen.

Check any back draft dampers in the exhaust ductwork. Inspect and remove any lint which can cause the damper to bind or stick. A back draft damper that is sticking partially closed can result in slow drying and the shutdown of heat circuit safety switches and thermostats.

Theory of Operation: Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (8-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 “LOCKOUT” if the gas burner flame is not sensed at the end of the trial for ignition period. The trial for ignition period will be repeated for a total of three retries/trials (the initial try and two more retries/trials). If the flame is not sensed at the end of the third retry/trial (inter-purge period of 30-seconds), the DSI module will “LOCKOUT” (a red L.E.D. diagnostic indicator will flash).

An unlit red L.E.D. diagnostic indicator indicates normal operation.

A lit green L.E.D. diagnostic indicator indicates dryer controller is calling for heat and that all interlocks have been satisfied.

Manual Reset Hi-Limit Instructions

WARNING
