INSTALLATION PROCEDURES
Installation should be performed by competent technicians in accordance with local and state codes. In the
absence of these codes, the installation must conform to applicable American National Standards: ANSI Z223.1LATEST EDITION (National Fuel Gas Code) or ANSI/NFPA NO. 70-LATEST EDITION (National Electrical
Code) or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91
(Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General
Installation and Gas Plumbing) or Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION
(for Electrical Connections).
A. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap and/or optional shipping box) from dryer.
NOTE: The access keys for the service doors are included in the information packet shipped in the
basket (tumbler). These keys should be removed and put in a safe place yet made accessible
because some will be needed throughout various phases in the installation of the dryer.
Dryers are shipped with a coin box and coin box faceplate ONLY. The coin box lock is not included and
must be purchased elsewhere or the lock can be ordered as a parts order from the manufacturer.
The dryer can be moved to its final location while still attached to the skid or with the skid removed. To unskid
the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are
at the rear of the base, and two (2) are located in the front. Once the bolts are removed, slide the dryer off the
skid.
With the skid removed, to make it easier to slide the dryer into its final position, slightly lower ALL four (4)
leveling legs, so that the dryer will slide on the legs instead of the base frame. The dryer is equipped with four
(4) leveling legs, one (1) at each corner of the dryer base. The hex head adjustment bolts for the two (2) front
leveling legs are located directly behind the lower access door, and the rear two (2) adjustments are directly
behind the lower rear back (guard) panel.
To facilitate door closure and better tumbling action (and improved efficiency), the dryer should be tilted slightly
to the rear.
B. LOCATION OF THE DRYER
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 Canadian Installation Codes CAN/CGA-B149.1-M91 (Natural Gas) or CAN/
CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION.

IMPORTANT: “The dryer must be installed on noncombustible floors only.”
2. The dryer must not be installed or stored in an area where it will be exposed to water or weather.
3. The dryer is for use in noncombustible locations.
4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply
Requirements in Section D).
5. Clearance provisions must be made from noncombustible construction as noted in this manual (refer to
Dryer Enclosure Requirements in Section C).
Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be
positioned approximately 2 feet (0.61 meters) away from the nearest obstruction, i.e., wall, for ease of
installation, maintenance, and service. (Refer to the illustration below.)
6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements in Section C).
7. Dryer must be exhausted to the outdoors in an area where correct exhaust venting can be achieved as
noted in this manual (refer to Exhaust Requirements in Section E).
IMPORTANT: 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).
8
Maytag
113203-3
8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual
(refer to Exhaust Requirements in Section E).
IMPORTANT: Dryer should be located where a minimum amount of exhaust duct will be necessary.
9. The dryer must be installed with a proper exhaust duct connection to the outside.
10. The dryer must be installed with provisions for adequate combustion and make-up air supply.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6
months, inspect the exhaust ducting and remove any lint build up.
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 [18-inches [45.72 cm] or more is recommended for ease of installation, maintenance, and
service]) above the dryer’s outer top, except along the front of the dryer which may be closed in if desired.
NOTE: Even though a minimum of 12-inches (30.48 cm) above the dryer’s outer top is acceptable, a
clearance of 18-inches (45.72 cm) or more is suggested for ease of installation and service
(electrical power connections).
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 12-inches (30.48 cm)
above the dryer’s outer top is required.
NOTE: Allowances must be made for the opening of the control door.
Dryers may be positioned sidewall to sidewall. However, allowances must be made for the opening and closing
of the control door and the lint door. It is suggested that the dryer be positioned about 2 feet (0.61 meters) away
from the nearest obstruction for ease of installation, maintenance, and service (to be measured from the back
guard). Refer to the illustration on the previous page for details.
NOTE: Air considerations are important for proper and efficient operation.
113203-3
Maytag

D. FRESH AIR SUPPLY REQUIREMENTS
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An
unrestricted source of 800 cfm (22.65 cmm) is necessary for each dryer. 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. This
area must be enlarged if louvers or registers cover the opening. 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 the dryers. For example, for a bank of eight
(8) dryers, a total make-up air opening of 12 square feet (1.15 square meters) is required. Two (2) openings
measuring 2 feet by 3 feet (0.61 meters by 0.91 meters [6 square feet] [0.56 square meters]) are acceptable.
The dryer must be installed with provisions for adequate combustion and make-up air supply.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low-pressure areas.
IMPORTANT: Make-up air must be provided from a source 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.
IMPORTANT: Make-up air openings should not be located near ductwork exhaust outlets. If
make-up air openings are too close to the exhaust outlet, lint and fumes may be drawn
back into the dryer area through these openings.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
10
Maytag
113203-3
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, overheating of the dryer,
and shut down of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats.
The dryer must be installed with a proper exhaust duct connection to the outside.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
The exhaust 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. When single dryer 10-inch (25.4 cm) vertical venting is used, the
ductwork from the dryer to the outside exhaust outlet must not exceed 35 feet (10.67 meters) or for 10-inch
(25.4 cm) horizontal venting, must not exceed 10 feet (3.05 meters). In the case of multiple (common) dryer
venting, the distance from the last dryer to the outside exhaust outlet must not exceed 15 feet (4.57 meters).
The shape of the exhaust ductwork is not critical as long as the minimum cross-sectional area is provided.
It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles instead. Excluding basket
(tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more than two (2)
elbows should be used in the exhaust duct run. If more than two (2) elbows are used, the cross section area of
the ductwork must be increased in proportion to the number of elbows added.
1. Exhaust Connections of Top and Bottom Baskets (Tumblers)
There is no common venting connection provided with the dryer. Each basket (tumbler) exhaust duct is
provided with its own back draft damper. Each basket (tumbler) can be exhausted directly outdoors
independently or connected to a common duct. Both single and common ductwork can be rigid ducting or
flexible ducting. For common connections, a kit (P/N 882035) is available from the factory and includes the
necessary flex ducting, elbows, and “Y” assembly, etc., to join the top and bottom exhausts together.
ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building.
IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust
duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) water
column (W.C.) when both baskets (tumblers) are operating.
NOTE: Common exhaust connections of top and bottom baskets (tumblers) should be installed in
such a manner that the back guards can be removed easily for servicing.
IMPORTANT: It is recommended that exhaust or booster fans NOT BE USED in the exhaust
ductwork system.
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 [0.05 mm]) thick.”
113203-3
Maytag
11
2. Single Dryer Venting
Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust 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. It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles
instead. The shape of the exhaust ductwork is not critical as long as the minimum cross-sectional area is
provided.
NOTE: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no
less than 0 and must not exceed 0.3 inches (0.74 mb) water column (W.C.).
It is suggested that the ductwork from each dryer not exceed the limitations noted in this manual. If the
ductwork exceeds these limitations or has numerous elbows, the cross-sectional area of the ductwork must
be increased in proportion to length or number of elbows in it.
IMPORTANT: For extended ductwork runs, the cross-sectional 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 heating, ventilating, and air-conditioning (HVAC) firm
should be consulted for proper venting information.
The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the
building. Also, inspection doors should be installed at strategic points in the exhaust ductwork for periodic
inspection and cleaning.
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.
To protect the outside end of the horizontal ductwork from the weather, a 90º elbow bent downward should
be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the
roof, it should be protected from the weather by using a 180º turn to point the opening downward. In
either case, allow at least twice the diameter of the duct between the duct opening and nearest obstruction.
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust
ductwork.
NOTE: Refer to the illustrations on page 13 and page 14 for examples of single dryer venting.

3. 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 10-inch (25.4 cm) duct (when dryer common exhaust is used) is
added. If single 6-inch (15.24 cm) basket (tumbler) exhaust ducts are used, the diameter should be
increased after every second 6-inch (15.24 cm) duct.
IMPORTANT: No more than four (4) dryers or eight (8) baskets (tumblers) total should be
connected to one (1) main common duct.
NOTE: Refer to the illustrations on page 17 for examples of multiple dryer (common) venting.
The main duct may be any shape or cross-sectional area as long as the minimum cross-sectional area is
provided. The illustrations on page 17 show the minimum cross-sectional area for multiple dryer venting.
These figures must be increased in proportion if the main duct run from the last dryer to where it exhausts
to the outdoors is unusually long (over 15 feet [4.57 meters]) or has numerous elbows (more than one [1])
in it. In calculating ductwork size, the cross-sectional area of a square or rectangular duct must be
increased twenty percent (20%) for each additional 15 feet (4.57 meters). The diameter of a round
exhaust must be increased ten percent (10%) for each additional 15 feet (4.57 meters).
IMPORTANT: For extended ductwork runs, the cross-sectional area of the ductwork can only be
increased to an extent. Maximum proportional ductwork run cannot exceed 15 feet
(4.57 meters) more than the original limitations of 15 feet (4.57 meters) with two (2)
elbows. When the ductwork approaches the maximum limits as noted in this manual,
a professional heating, ventilating, and air-conditioning (HVAC) firm should be
consulted for proper venting information.
IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust
duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) water
column (W.C.).
The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the
building. Also, inspection doors should be installed at strategic points in the exhaust ductwork for periodic
inspection and cleaning.
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.

3. Piping/Connections
ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST
EDITION, or in Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid
Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing), as well as local
codes and ordinances and must be done by a qualified professional. 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.
The dryer is provided with two (2) 1/2” N.P.T. inlet pipe connections (one [1] for each basket [tumbler]) at
the rear of the dryer. If a separate feed is provided for each basket (tumbler) from the main supply line
(header), then a 1/2” (12.7 mm) line connection is sufficient. However, if the top and bottom basket
(tumbler) connections are connected together, the supply from the header must be increased to 3/4-inch
(19.05 mm). An optional piping kit is available from the factory as illustrated below and on page 39. It is
recommended that a gas shutoff valve be provided to the gas supply line of each dryer for ease in servicing.
TYPICAL GAS CONNECTIONS
IMPORTANT: When plumbing upper and lower baskets (tumblers) together, as illustrated above,
supply connection must be a minimum of 3/4” (19.05 mm).
22
Maytag
113203-3
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 liquid propane [L.P.] gas, the supply tank), the number of tees, other
gas-operated appliances on the supply 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.
Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4” (19.05 mm)
pipe loop be installed in the supply line servicing the bank of dryers. An in-line pressure regulator must be
installed in the gas supply line (header) if (natural) gas line pressure exceeds 12.0 inches (29.9 mb) water
column (W.C.) pressure. Refer to the illustration on page 24 for details.
IMPORTANT: Water column pressure of 3.5 inches (8.7 mb) for natural gas dryers and 10.5 inches
(26.1 mb) for L.P. gas is required at the gas valve pressure tap of each dryer for
proper and safe operation.
A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply
line immediately upstream of each dryer.
IMPORTANT: Pipe joint compounds that resist the action of natural gas and L.P. gas must be used.
WARNING: Test ALL connections for leaks by brushing on a soapy water solution (liquiddetergent
also works well). NEVER TEST FOR GAS LEAKS WITH AN OPEN FLAME!!!

H. PREPARATION FOR OPERATION
The following items should be checked before attempting to operate the dryer:
1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.
2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label.
3. GAS MODELS – check to ensure that the dryer is connected to the type of heat/gas indicated on the
dryer data label.
4. GAS MODELS – the sail switch damper assembly was installed and adjusted at the factory prior to
shipping. However, each sail switch adjustment must be checked to ensure that this important safety
control is functioning.
5. Check bolts, nuts, screws, terminals, and fittings for tightness.
6. GAS MODELS – be sure that ALL gas shutoff valves are in the open position.
7. Be sure ALL back guard panels and service box covers have been replaced.
8. Check the lint door to ensure that it is closed and secured in place.
9. Rotate the basket (tumbler) by hand to be sure they move freely.
10. To facilitate door closure and better tumbling action (and improved efficiency), the dryer should be tilted
slightly to the rear.
I. PREOPERATIONAL TESTS
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.
1. Turn on electric power to the dryer: open ALL gas shutoff valves.
2. Computer System Operational Test
a. Coin Models
1) The liquid crystal display (L.C.D.) screen reads “Ready,” insert amount to start (i.e. 25¢).

IMPORTANT: For complete operation details for the computer system refer to the user’s manual
included with the dryer.
3. Heat Circuit Operational Test
Gas Models
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.
The dryer is equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If ignition
is not established after three (3) attempts, the heat circuit DSI module will lock out until it is manually reset.
To reset the DSI system, open and close the main door and restart the dryer (press desired temperature
selection).
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each
dryer to ensure that the water column (W.C.) pressure is correct and consistent.
26
Maytag
113203-3
NOTE: Water column (W.C.) pressure requirements (measured at the gas valve pressure tap):
Natural Gas .............................. 3.5 Inches (8.7 mb) Water Column.
Liquid Propane (L.P.) Gas ........ 10.5 Inches (26.1 mb) Water Column.
IMPORTANT: 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.
4. Make a complete operational check of ALL safety-related circuits (i.e., lint basket switches and sail
switches).
5. Each basket (tumbler) should be operated through one (1) complete cycle to ensure that no further
adjustments are necessary and that ALL components are functioning properly.
NOTE: The sail switch can be checked for proper operation by opening the control door while the
dryer is running and the heating unit (burner) is active (on). The heating unit should shut off
within a few seconds. If not, make the necessary adjustments.
BASKET (TUMBLER) COATING
The basket (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 basket (tumbler) to remove
this coating.
NOTE: Drying and cooling cycles are complete when the light emitting diode (L.E.D.) display reads
“donE.”
6. Computer Programs/Selections:
Each Dual Microprocessor Controller (DMC) computer has been preprogrammed by the factory with the
most commonly used program (parameter) selections. If microprocessor controller (computer) program
changes are required, refer to the Dual Microprocessor Controller (DMC) Programming Manual,
which was shipped with the dryer.

ROUTINE MAINTENANCE
A. 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 air
circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, this 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.
WARNING: 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 six (6) to eight (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 build up.
SUGGESTED CLEANING SCHEDULE
DAILY (beginning of each work shift)
Clean lint from lint drawer/screen.
Inspect lint screen and replace if torn.
WEEKLY
Clean lint accumulation from around microprocessor temperature sensor probes and sensor bracket assemblies.
WARNING: TO AVOID HAZARD OF ELECTRICAL SHOCK, DISCONTINUE
ELECTRICAL POWER SUPPLY TO THE DRYER.
90 DAYS
Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from the dryer’s
internal exhaust ducting.

Maytag
113203-3
WARNING: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
WARNING: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AIR AND
VENTILATION AIR.
WARNING: INSPECT AND REMOVE ANY LINT ACCUMULATION, WHICH CAN
CAUSE THE BACK DRAFT DAMPER TO BIND OR STICK.
NOTE: A back draft damper that is sticking partially closed can result in slow drying and shut down of
the heat circuit safety switches and/or thermostats.
NOTE: When cleaning dryer cabinet(s), avoid using harsh abrasives. A product intended for the
cleaning of appliances is recommended.
B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION and EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws, setscrews, grounding connections, and nonpermanent gas connections (unions, shutoff
valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed belt(s) should
be replaced. Tighten loose belt(s) when necessary. Complete operational check of controls and valves. Complete
operational check of ALL safety devices (door switches, lint drawer switch, sail switch, burner, and hi-limit
thermostats).
C. LUBRICATION
The motor bearings, idler bearings, and under normal/most conditions the basket (tumbler) bearings are permanently
lubricated. It is physically impossible to re-lubricate the basket (tumbler) bearings if you choose to do so, even
though this practice is not necessary. Use Shell Alvania #2 grease or its equivalent. The basket (tumbler)
bearings used in the dryer DO NOT have a grease fitting. Provisions are made in the bearing housing for the
addition of a grease fitting, which can be obtained elsewhere, or from the Maytag dealer by ordering
P/N 882159 (which includes two [2] grease fittings).

1. 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. The trial for ignition period will
be repeated for a total of three (3) retries/trials (the initial try and
two [2] 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 “LOCK OUT” (light emitting diode [L.E.D.] diagnostic
indicator flashes).
A steady L.E.D. indicator indicates normal operation.
No L.E.D. indicator indicates a power or an internal failure has occurred.
2. For Models with Fenwal Controls DSI Module (128937)
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 “LOCK OUT” 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 (3) retries/trials (the initial try and
two [2] 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 “LOCK OUT” (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.
