Safety Practices for Servicer

Safe and satisfactory operation of gas ranges depends

upon its design and proper installation. However, there is

one more area of safety to be considered:

Servicing

Listed below are some general precautions and safety

practices which should be followed in order to protect

the service technician and consumer during service and

after service has been completed.

1. Gas smell—Extinguish any and all open flames and

open windows.

2. Turn gas off—Service range with gas turned off

unless testing requires it.

Important Safety Information

3. Checking for gas leaks—Never check for leaks with

any kind of open flame. Soap and water solution

should be used for this purpose. Apply solution to

suspected area and watch for air bubbles which

indicates a leak. Correct leaks by tightening fittings,

screws, connections, applying approved compound,

or installing new parts.

4. Using lights—Use a hand flashlight when servicing

ranges or checking for gas leaks. Electric switches

should not be operated where leaks are suspected.

This will avoid creating arcing or sparks which could

ignite the gas. If electric lights are already turned on,

they should not be turned off.

5. Do not smoke—Never smoke while servicing gas

ranges, especially when working on piping that

contains or has contained gas.

6. Check range when service is completed—After

servicing, make visual checks on electrical

connection, and check for gas leaks. Inform

consumer of the condition of range before leaving.

7. Adhere to all local regulations and codes when

performing service.

Receiving Oven

• Installer needs to show consumer location of the range

gas shut-off valve and how to shut it off.

• Authorized servicer must install the range, in

accordance with the Installation Instructions.

Adjustments and service should be performed only by

authorized servicer.

• Plug range into a 120–volt grounded outlet only. Do

not remove round grounding prong from the plug. If in

doubt about grounding of the home electrical system, it

is consumers responsibility and obligation to have an

ungrounded outlet replaced with a properly grounded

three-prong outlet in accordance with the National

Electrical Code. Do not use an extension cord with this

appliance.

• Insure all packing materials are removed from the

range before operating it, to prevent fire or smoke

damage should the packing material ignite.

• Ensure range is correctly adjusted by a qualified

service technician or installer for the type of gas

(Natural or LP). Some ranges can be converted for

use with Natural or LP gas.

•With prolonged use of a range, high floor

temperatures could result. Many floor coverings will not

be able to withstand this kind of use. Never install

range over vinyl tile or linoleum that cannot withstand

high temperatures. Never install range directly over

carpeting.

Using the Oven

• Do not leave children alone or unattended where a

range is hot or in operation. They could be seriously

burned.

• Do not allow anyone to climb, stand or hang on the

door. They could damage the range and cause severe

personal injury.

• Wear proper apparel. Loose fitting or hanging

garments should never be worn when using oven.

Flammable material could ignite if brought in contact

with flame or hot oven surfaces which may cause

severe burns.

• Never use range for warming or heating a room. This

may cause burns, injuries, or a fire.

• Do not use water on grease fires.

• Do not let grease or other flammable materials collect

in or around range.

• Do not repair or replace any part of range unless it is

recommended in this manual.

• Use only dry potholders. Moist or damp potholders

used on hot surfaces may result in a burn from steam.

Do not let a potholder touch the flame. Do not use a

towel or a bulky cloth as a potholder.

• Never leave range unattended while cooking. Boilovers

can cause smoking and may ignite.

• Only certain types of glass/ceramic, earthenware, or

other glazed utensils are suitable for oven use.

Unsuitable utensils may break due to sudden

temperature change.

• Use care when opening oven door. Let hot air or steam

escape before removing or replacing food.

• Do not heat unopened food containers in oven.

Build-up of pressure may cause a container to burst

and result in injury.

• Keep range vent ducts unobstructed.

• Place oven racks in desired location while oven is

cool. If a rack must be moved while oven is hot, use a

dry potholder.

• Do not use aluminum foil to line oven bottom or racks.

Aluminum foil can cause a fire will seriously affect

baking results, and damage to porcelain surface's.

• Do not touch interior surfaces of oven during or

immediately after use. Do not let clothing or other

flammable materials come in contact with bake or broil

burners.

• Other areas of the oven can become hot enough to

cause burns, such as vent openings, window, oven

door and oven racks.

• To avoid steam burns, do not use a wet sponge or

cloth to wipe up spills on hot cooking area.

• Do not store combustible or flammable materials, such

as, gasoline or other flammable vapors and liquids

near or in oven.

• Do not clean oven door gasket located on back of the

door. Gasket is necessary to seal the oven and can be

damaged as a result of rubbing or being moved.

• Do not drape towels or any materials on oven door

handles. These items may ignite causing a fire.

Important Safety Information

CAUTION

above range. Children may climb on oven to reach

these items and become seriously injured.

Baking, Broiling, and Roasting

• Do not use oven area for storage.

• Stand back from range when opening door of a hot

oven. Hot air or steam can cause burns to hands,

face, and eyes.

• Do not use aluminum foil anywhere in the oven. This

could result in a fire hazard and damage the range.

• Use only glass cookware appropriate for use in gas

ovens.

• Always remove broiler pan from oven when finished

broiling. Grease left in pan can catch fire if oven is

used without removing grease from the broiler pan.

• When broiling, meat that is close to the flame, may

ignite. Trim any excess fat to help prevent excessive

flare-ups.

• Make sure broiler pan is placed correctly to reduce

any possibility of grease fires.

• Should a grease fire occur in the broiler pan, turn off

oven, and keep oven door closed until fire burns out.

Connecting Range to Gas

Install manual shut-off valve in gas line for easy

accessibility outside range. Be aware of the location of

the shut-off valve.

Electrical Requirements

120-volt, 60 Hertz, 20 amp, individual circuit which is

properly grounded, polarized and protected by a circuit

breaker or fuse.

Extension Cord

Do not use extension cords with this product.

Product Safety Devices

Safety devices and features have been engineered into

the product to protect consumer and servicer. Safety

devices must never be removed, bypassed, or altered in

such a manner as to defeat the purpose for which they

were intended.

Listed below are various safety devices together with the

reason each device is incorporated in the gas ranges.

Pressure Regulator Maintains proper and

steady gas pressure for

operation of oven

controls.

Regulator must be set

for the type of gas being

used Natural or LP.

After servicing regulator,

make certain it is set

properly before

completing service.

Gas Burner Orifices Universal orifices are

used on most valves.

They must be adjusted

for the type of gas being

used Natural or LP.

After servicing a valve

or orifice verify it is

adjusted properly before

completing service.

Oven Safety Valve Oven valve is designed

to be a safety valve. Two

basic designs are used

in gas ranges:

Hydraulic and Electric

Both types are safety

valves because they are

indirectly operated by

the oven thermostat,

which controls a pilot

flame or electric ignitor,

to open and close the

oven valve.

Grounded Oven Frame Ground prong on power

cord is connected to the

frame, usually a green

lead fastened by a

screw. In addition, any

part or component

capable of conducting

an electric current is

grounded by its

mounting.

If any ground wire,

screw, strap, nut, etc. is

removed for service, or

any reason, it must be

reconnected to its

original position with

original fastener before

the appliance is put into

operation again.

Failure to do so can

create a possible shock

hazard.

This manual contains information needed by authorized

service technicians to install and service gas ranges.

There may be, however, some parts which need further

explanation. Refer to the Installation Instructions, Use

and Care, Technical Sheets or the toll-free technical

support line.

This manual provides basic instructions and suggestions

for handling, installing and servicing gas ranges.

The directions, information, and warnings in this manual

are developed from experience with, and careful testing

of the product. If the unit is installed according to this

manual, it will operate properly and will require minimal

servicing. A unit in proper operating order ensures the

consumer all the benefits provided by clean, modern gas

cooking.

General Information

Grounding

NOTE: This appliance must be properly grounded, for

personal safety.

Power cord on this appliance is equipped with a three-

prong grounding plug. This matches standard three-

prong grounding wall receptacle to prevent possibility of

electric shock from this appliance.

Consumer should have wall receptacle and circuit

checked by qualified electrician to verify receptacle is

properly grounded.

It is the consumers responsibility to replace standard two-

prong wall receptacles with properly grounded three-prong

wall receptacles.

DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR

REMOVE THE THIRD (GROUND) PRONG FROM

POWER CORD.

For 15 amp circuits only, do not use an adapter on 20

amp circuit. Where local codes permit, a TEMPORARY

CONNECTION may be made to a properly grounded two-

prong wall receptacle by the use of a UL listed adapter

(available at most hardware stores).

Larger slot on adapter must be aligned with larger slot in

the wall receptacle to provide proper polarity.

WARNING

Attaching adapter ground terminal to wall receptacle

cover screw does not ground appliance unless the

cover screw is metal and not insulated, and wall

receptacle is grounded through the house wiring.

Consumer should have circuit checked by a qualified

electrician to verify receptacle is properly grounded.

When disconnecting power cord from adapter, always

hold adapter with one hand. If this is not done, adapter

ground terminal is very likely to break with repeated use.

Should this happen, DO NOT USE appliance until a

proper ground has been established.

Description of Fault Codes for EOC III

Each fault code consists of 4 digits and is structured as follows:

1st (Leftmost) Digit:

Primary Failure System 2nd Digit: Alpha-Character 3rd Digit: Secondary

Failure Mechanism 4th Digit : Oven

Cavity Number

1 – Local to Control System d – Diagnostic Failure (measurable) 1 – Upper (Single) Oven

3 – Sensor or Meat Probe c – Control-Related Error (not measurable) 2 – Lower Oven

4 – Input to Control System

c – Control System

9 – Door Lock

If a fault is detected, then one of the following three messages will be scrolled on the display:

FAULT DETECTED PRESS ENTER TO TRY AGAIN. This message displays when a fault is detected while a

cooking function is active. Clear by pressing the Cancel keypad.

FEATURE NOT AVAILABLE. This message displays when a fault is detected while entering data during initial

programming and also when a locked out function is detected. Clear by pressing any key.

FAULT DETECTED DISABLE POWER TO CLEAR. This message displays when a runaway temperature condition

is detected while the control is in idle mode. Press any key to clear the message, but the fault remains until the

control senses a Power-On reset.
