WARNING !
WHAT TO DO IF YOU SMELL GAS:
IMPORTANT SAFETY NOTICE
The information in this service guide is intended for use by individuals possessing skill and experience in
electrical, electronic, and mechanical appliance repair. Any attempt to repair a major appliance may result
in injury to persons, and property damage. The manufacturer or seller cannot be responsible for the
interpretation of this information, nor can it assume any liability in connection with its use.
RECONNECT ALL GROUNDING DEVICES
If grounding wires, screws, straps, clips, nuts, or washers used to complete a path to ground are
removed for service, they must be returned to their original position and properly fastened.
IMPORTANT
Electrostatic Discharge (ESD) Sensitive Electronics
ESD problems are present everywhere. ESD may damage or weaken the electronic
control assembly. The new control assembly may appear to work well after repair is
finished, but failure may occur at a later date due to ESD stress.
Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted
metal in the appliance.
- OR -
Touch your finger repeatedly to a green ground connection point or unpainted metal
in the appliance.
Before removing the part from its package, touch the anti-static bag to a green ground connection
point or unpainted metal in the appliance.

Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

When repackaging the failed electronic control assembly in an anti-static bag, observe the instructions above.
Do not try to light a match, or cigarette, or turn on
any gas or electrical appliance.
Do not touch any electrical switches. Do not use
any phone in your building.
Clear the room, building, or area of all occupants.
Immediately call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions carefully.
If you cannot reach your gas supplier, call the fire
department.

WARNING
Retract fully
Retainer
T-clip
Make sure the leveling feet of the dryer are
fully retracted.
NOTE: The appliance and pedestal assembly
must be placed on a solid, sturdy, level floor
for proper operation.
Insert the T-clip of the 4 retainers into the dryer
base as shown. Press up on the back of the
clip and pull outward to lock into place.
Place the dryer on the
pedestal. Make sure
the front and back feet
are in the correct
positions. The dryer
feet will fit into the
innermost positions as
shown.
Make sure the screws on the pedestal align with the
holes in the retainers, then install 4 screws on each
side to securely attach the appliance to the pedestal.
NOTE: If the screws are not installed properly, noise
and vibration may result.
Move the appliance to the desired location.

WARNING
To reduce the risk of fire, electric shock, or injury to persons when using this appliance, follow basic precautions, including the following:
Electrical Requirements for Gas Models Only
WARNING
To reduce the risk of fire, electric shock, or Injury to persons when using this appliance, follow basic precautions, including the following:
Do not, under any circumstances, cut or remove the third
(ground) prong from the power cord. Failure to follow this
warning can result in fire, explosion, or death.
For personal safety, this dryer must be properly grounded.
Failure to follow this warning can result in fire, explosion, or death.
The power cord of this dryer is equipped with a 3-prong
(grounding) plug which mates with a standard 3-prong
(grounding) wall outlet to minimize the possibility of electric
shock hazard from this appliance. Failure to follow this warning
can result in fire, explosion, or death.
This dryer must be plugged into a 60 Hz, 120 VAC, grounded
outlet protected by a 15-ampere fuse or circuit breaker. Failure
to follow this warning can result in fire, explosion, or death.
Where a standard 2-prong wall outlet is encountered,it is your
personal responsibility and obligation to have it replacedwith
a properly grounded 3-prong wall outlet. Failure to follow this
warning can result in fire, explosion, or death.
Gas supply requirements:
As shipped from the factory, this dryer is configured for use
with naturalgas.It canbeconverted for usewith LP (Liquefied
Propane) gas. Gas pressure must not exceed 13 inches of
water column.
A qualified service or gas company technician must connect
the dryer to the gas service.
Failure to do so can result in fire, explosion, or death.
Isolate the dryer from the gas supply system by closing its
individual manual shutoff valve during any pressure testing
of the gas supply.
Failure to do so can result in fire, explosion, or
death.
Supply line requirements:
Your laundry room must have a rigid gas supply line to your
dryer. In the United States, an individual manual shutoff valve
MUST be installed within at least 6 ft. (1.8 m) of the dryer, in
accordance with the National Fuel Gas Code ANSI Z223.1 or
Canadian gas installation code CSA B149.1. A
18
pipe plug must be installed. Failure to do so can result in fire,
explosion, or death
If using a rigid pipe, the rigid pipe should be ½ - inch IPS.
If acceptable under local codes and ordinances and when
acceptable to your gas supplier, 38roved tubing
may be used where lengths are less than 20 ft. (6.1 m). Larger
tubing should be used for lengths in excess of 20 ft. (6.1 m).
Failure to do so can result in fire, explosion, or death.
Connect the dryer to the type of gas shown on the nameplate.
Failure to do so can result in fire, explosion, or death.
To prevent contamination of the gas valve, purge the gas
supply of air and sediment before connecting the gas supply
to the dryer. Before tightening the connection between the
gas supply and the dryer, purge remaining air until the odor
of gas is detected.Failure to do so can result in fire, explosion, or
death.
DO NOT use an open flame to inspect for gas leaks. Use a
noncorrosive leak-detection fluid. Failure to do so can result in
fire, explosion, or death.
Use only a new AGA- or CSA-certified gas supply line with
flexible stainless steel connectors. Failure to do so can result in
fire, explosion, or death.
Securely tighten all gas connections. Failure to do so can result
in fire, explosion, or death.
DO NOT attempt any disassembly of the dryer; any
disassembly requires the attention and tools of an authorized
and qualified service person or company. Failure to do so can
result in fire, explosion, or death.
Use a pipe-joint compound that is insoluble in Liquefied
Petroleum (LP) gas on all pipe threads. Failure to do so can
result in fire, explosion, or death.

WARNING
To reduce the risk of fire, electric shock, or injury to persons when
using this appliance, follow basic precautions, including the
following:
Installation and service must be performed by a qualified
installer, service agency, or the gas supplier. Failure to do so
can result in fire, explosion, or death.
Use only a new stainless steel flexible connector and a new
AGA-certified connector. Failure to do so can result in fire,
explosion, or death.
A gas shutoff valve must be installed within 6 ft. (1.8 m) of
the dryer. Failure to do so can result in fire, explosion, or death.
The dryer is configured for Natural Gas when shipped from
the factory. Make sure that the dryer is equipped with the
correct burner orifice for the type of gas being used (Natural
Gas or Liquefied Petroleum). Failure to do so can result in fire,
explosion, or death.
If necessary, the correct orifice (for the LP, orifice kit order
part number 383EEL3002D) should be installed by a
qualified technician and the change should be noted on the
dryer. Failure to do so can result in fire, explosion, or death.
All connections must be in accordance with local codes and
regulations . Failure to do so can result in fire, explosion, or
death.
Gas dryers MUST exhaust to the outdoors.Failure to do so can
result in fire, explosion, or death.
Connecting the Gas Supply
1.Make sure that the gas supply to the laundry room is turned
OFF. Confirm that thetypeof gas available in your laundry room
is appropriate for the dryer. The dryer is prepared for Natural
Gas with a

2.Remove the shipping cap from the gas connection at the back
of the dryer. Be careful not to damage the threads of the gas
connector when removing the shipping cap.
3.Connect the dryer to your laundry room’s gas supply using a
new flexible stainless steel connector with a

4.Securely tighten all connections between the dryer and your
laundry room’s gas supply. Turn on your laundry room’s gas
supply and check all pipe connections (both internal and
external) for gas leaks with a noncorrosive leak-detection fluid.
