To avoid risk of fire, electric shock, serious injury, or death when using your dryer, follow these basic precau-
tions:
1. Read all instructions before using dryer.
2. Install dryer according to Installation Instructions. Refer to the Grounding Instructions in the
Installation Instructions for proper grounding of the dryer.
3. Do not dry articles that have been cleaned in, washed in, soaked in, or spotted with gasoline, dry-
cleaning solvents, or other flammable or explosive substances. Vapors could ignite or explode.
4. Do not use dryer to dry clothes which have traces of any flammable substance, such as vegetable oil,
cooking oil, machine oil, flammable chemicals, thinner, etc., or anything containing wax or chemicals,
such as mops and cleaning cloths. Flammable substances may cause fabric to catch fire by itself.
5. Do not store or use gasoline or other flammable vapors and liquids near this or any other appliance.
6. Do not allow children to play on or in dryer. Close supervision of children is necessary when dryer is
used near children, a safety rule for all appliances.
7. Before dryer is removed from service or discarded, remove doors to drying compartment.
8. Do not reach into dryer if cylinder is revolving.

12. To reduce risk of electric shock or fire, do not use extension cords or adapters to connect dryer to
electrical power source.
13. Use the dryer only for its intended purpose, drying clothes.
14. Always disconnect dryer from electrical supply before attempting any service. Disconnect power cord by
grasping the plug, not the cord.
15. Do not use heat to dry articles containing foam rubber or similarly textured rubberlike materials.

16. Always clean the lint filter after every load. A layer of lint in the filter reduces drying efficiency and pro
longs drying time.
17. Use only fabric softeners or products to eliminate static that are appropriate for automatic dryers.
18. Keep your dryer in good condition. Bumping or dropping dryer can damage safety features. If damage
occurs, have dryer checked by qualified service technician.
19. Replace worn power cords and/or loose plugs.
20. Do not tumble fiberglass curtains and draperies unless the label says it can be done. If they are dried, wipe
out the cylinder with a damp cloth to remove particles of fiberglass.
21. Always read and follow manufacturers instructions on packages of laundry aids. Heed all warnings or
precautions. To reduce risk of poisoning or chemical burns, keep products away from children at all times,
preferably, in a locked cabinet.
22. Never operate dryer with guards and/or panels removed.
23. Do not operate dryer with missing or broken parts.
24. Do not bypass safety devices.
25. Keep area around the exhaust opening and adjacent surrounding areas free from accumulation of
lint, dust, and dirt.
26. Interior of dryer and exhaust duct should be cleaned periodically by qualified service personnel.
27. Dryer will not operate with loading door open. DO NOT bypass door safety switch by permitting dryer to
operate with door open. Dryer will stop tumbling when door is opened. Do not use dryer if it does not stop
tumbling when door is opened or starts tumbling without pressing or turning the START mechanism.

To avoid risk of personal injury or death due
to electrical shock:
- Observe all local codes and ordinances.
- Disconnect electrical power to unit
before servicing.
- Ground appliance properly.
- Check with a qualified electrician if you
are not sure this appliance is properly
grounded.
- DO NOT ground to gas line.
- DO NOT ground to cold water pipe if
pipe is interrupted by plastic, nonmetallic
gas kets, or other insulating
(nonconducting) materials.
- DO NOT modify plug on power cord.
If plug does not fit electrical outlet, have
proper outlet installed by qualified elec
trician.
- DO NOT have a fuse in the neutral or
ground circuit. A fuse in the neutral or
ground circuit could result in an electrical
shock.
- DO NOT use an extension cord with
this appliance.
- DO NOT use an adapter plug with
this appliance.
- DO NOT pinch powe cord.
ZDUQLQJ
To reduce the risk of fire and exposure to
combustion gases, the dryer MUST be ex-
hausted to the outdoors.
DO NOT exhaust dryer air into a window well,
gas vent, chimney or enclosed, unventilated
area, such as an attic, wall, ceiling, crawl
space under a building or concealed space of
a building.
ZDUQLQJ
To reduce the risk of fire, electric shock, seri-
ous injury or death, all wiring and ground-
ing must conform with the latest edition of
the National Electric Code, or the Canadian
Electrical Code, and such local regulations as
might apply. It is the customers responsibil-
ity to have the wiring and fuses checked by a
qualified electrician to make sure your home
has adequate electrical power to operate the
dryer.

This equipment MUST be grounded. In the
event of an electrical short circuit, grounding
reduces the risk of electric shock by providing
an escape wire for the electrical current. This
unit is equipped with a cord having a ground-
ing wire with a grounding plug. The plug must
be plugged into an outlet that is properly
installed and grounded.
Consult a qualified electrician or servicer if
grounding instructions are not completely un-
derstood, or if doubt exists as to whether the
equipment is properly grounded.
Do not use an extension cord. If the prod-
uct power cord is too short, have a qualified
electrician install a three  slot receptacle.
This unit should be plugged into a separate 60
hertz circuit with the electrical rating as shown
on the serial plate.

For the safety of our customers and the serv-
ice technician ALL gas dryers have a three!!
prong power cord and MUST be connected to
a properly polarized and grounded wall outlet.
This information was written for those who do
not understand grounding and polarization
of a wall outlet. A 120 VAC wall outlet must
always be wired as shown below.
Srodul}dwlrq-This means that the larger slot
must be neutral and the small slot must be hot
(live).
Plvsrodul}hg-The outlet is miswired so that the
larger slot is hot (live) and the smaller slot is
neutral.
Jurxqghg -This means the round hole con-
nection is connected to ground through a
connection to the main power panel.
Xqjurxqghg-The round hole connection is not
connected to a ground and/or the main power
panel.

DUCTING REQUIREMENTS
• Use a 4-inch (10.2 cm) diameter rigid aluminum or rigid galvanized steel duct.
• Do not use a smaller duct.
• Ducts larger than 4 inches (10.2 cm) in diameter can result in increased lint accumulation.
Lint accumulation should be cleaned regularly.
• If a flexible metal duct must be used, use the type with a stiff sheet metal wall. Do not use a flexible
duct with a thin foil wall. Serious blockage can result if the flexible metal duct is bent too sharply.
• Never install any type of flexible duct in walls, ceilings, or other concealed spaces.
• Keep exhaust duct as straight and short as possible.
• Secure joints with duct tape. Do not use screws.
• DO NOT EXHAUST DRYER INTO ANY WALL, CEILING, CRAWL SPACE, OR CONCEALED SPACE OF A
BUILDING, GAS VENT, OR ANY OTHER COMMON DUCT OR CHIMNEY.
THIS COULD CREATE A FIRE HAZARD FROM LINT EXPELLED BY THE DRYER.
• Plastic flexible duct can kink, sag, be punctured, reduce airflow, extend drying times, and affect dryer
operation.
• Exhaust systems longer than recommended can extend drying times, affect machine operation, and may collect lint.
• The exhaust duct should end with an exhaust hood with a swing-out damper to prevent back drafts
and entry of wildlife. Never use an exhaust hood with a magnetic damper.
• The hood should have at least 12 inches (30.5 cm) of clearance between the bottom of the hood and
the ground or other obstruction. The hood opening should point down.
• Never install a screen over the exhaust outlet.
• To avoid lint buildup, do not exhaust the dryer directly into a window well. Do not exhaust under a
house or porch.
• If exhaust ductwork must run through an unheated area, the duct should be insulated and slope
slightly down towards the exhaust hood to reduce condensation and lint buildup.
• Inspect and clean the interior of the exhaust system at least once a year. Unplug the power cord
before cleaning.
• Check frequently to be sure the exhaust hood damper opens and closes freely.
