WARNING
To reduce the risk of fire, electrical shock,
injury to persons, or damage when using
the range, follow these basic precautions:
1. Read all instructions before using the
range.
2. Install or locate the range only in accordance with the provided installation instructions. It is recommended that the
range be installed by a qualified installer.
The range must be properly connected to
the correct gas supply and checked for
leaks. The range must also be properly
connected to a grounded electrical supply.
3. Gas fuels and combustion can result in
potential exposure to chemicals known to
cause cancer or reproductive harm. For
example, benzene is a chemical which is
a part of the gas supplied to the range. It
is consumed in the flame during combustion. However, exposure to a small amount
of benzene is possible if a gas leak occurs. Formaldehyde and soot are by-products of incomplete combustion. Properly
adjusted burners with a bluish rather than
a yellow flame will minimize incomplete
combustion.
4. Do not use the range for heating the room.
Persons could be burned or injured, or a
fire could start.
5. Do not leave children alone or unattended
in area where the range is in use. They
should never be allowed to sit or stand on
any part of the range. They could be
burned or injured.
6. Do not wear loose or hanging garments
when using the range. Clothing could ignite if it touches a surface burner and you
could be burned.
7. Do not repair or replace any part of the
range unless specifically recommended
in this manual. All other servicing should
be referred to a qualified technician.
8. Do not operate the range if it is not working properly, or if it has been damaged or
dropped.
9. Know where your main gas shut off valve
is located.
10. Clean your range regularly. See “Care
and Cleaning” instructions that are included with the range.
11. Use the range only for its intended use as
described in this manual.
12. Do not store flammable materials on or
near the range. They could explode or
burn.
13. Do not use water on grease fires. Never
pick up a flaming pan. Smother flaming
pan on range by covering with a wellfitting lid, cookie sheet or flat tray. Flaming grease outside of pan can be extinguished with baking soda, or if available,
a multipurpose dry chemical or foam-type
extinguisher.
14. Use only dry potholders. Moist or damp
potholders on hot surfaces may result in
burns from steam. Do not let potholder
touch an open flame. Do not use a towel
or bulky cloth for a potholder. It could
catch on fire.
15. Make sure the utensils you use are large
enough to contain food and avoid boilovers
and spillovers. Heavy splattering or
spillovers left on a range can ignite and
burn you. Pan size is especially important
in deep fat frying.
16. Never leave burners unattended at high
flame settings. A boilover could result
and cause smoking and greasy spillovers
that may ignite.

17. Grease is flammable and should be
handled carefully. Let fat cool before attempting to handle it. Do not allow grease
to collect around range or in vents. Wipe
spillovers immediately.
18. Check to be sure glass cooking utensils
are safe for use on the range. Only certain
types of glass, glass-ceramic, earthenware or other glazed utensils are suitable
for ranges. Other types may break due to
the sudden change in temperature.
19. Turn pan handles inward, but not over
other burners. This will help reduce the
chance of burns, igniting of flammable
materials, and spills due to bumping the
pan.
20. Do not heat unopened containers. They
could explode. The hot contents could
cause burns and container particles could
cause injury.
21. Do not use decorative covers or trivets
over the surface burners.
22. Do not store things children might want
above the range. Children could be burned
or injured while climbing on range.
23. Do not touch hot burners or areas near
burners. Areas near burners become hot
enough to cause burns. During use, do
not touch or let clothing or other flammable materials contact burners, or areas near burners.
24. Do not block the ventilation.
25. Never use a match or other flame to look
for a gas leak. Explosion and injury could
result.
26. Make sure the burners are off when you
are finished, and when you are not watching.
27. Be sure all range parts are cool before
cleaning.

CHECKING THE MAINTOP BURNER OPERATION
1. Install the maintop burner caps on the burners.
2. If not already done, turn on the gas and
electrical supplies to the range.
3. Push and turn each of the maintop burner
knobs to the LITE position. You should hear a
snapping sound as the burner ignitors spark.
The gas at each burner should ignite after
approximately 4-seconds. When this occurs,
turn the knob to the HI setting. NOTE: Do not
leave the knob in the LITE position after the
burner lights, otherwise the ignitors will continue to spark.
4. Check the maintop burners for the proper
flame. The small inner cone should have a
very distinct blue flame that is approximately
5
/8" long. The outer cone will not be as distinct
as the inner cone. If the flame is noisy or is
blowing, there is too much air during combustion. If the flame is soft and not high enough,
there is not enough air. If either of these
conditions occur, adjust the air shutters, as
shown on the next page.
LO F LAME SETTING
ADJUSTMENT (SOME MODELS)
Some gas ranges have a low flame burner adjustment, located inside the shaft of each gas valve
(see the illustration below). To adjust the flame:
1. Turn the gas valve knob to its LOW, or SIMMER setting, and remove the control knob.
2. Adjust the screw inside the gas valve stem so
that the flame size is as small as possible
without going out when the valve is turned
quickly from the LITE position to WARM position.
3. Turn off the burners and reinstall the knob.
5. Turn the maintop burners off.

THEORY OF OPERATION
THE COOKTOP BURNERS
Refer to the illustration below while you read
this description.
When a surface burner control knob is turned
to the “lite” position, the gas valve r opens,
and gas from the pressure regulator s flows
into the manifold t, and through the open
valve. As gas passes through the valve and its
orifice, it is directed into the venturi u, where
it mixes with air to create the proper mixture
necessary for combustion.
At the same time, line voltage is applied through
the ignitor switch v to the ignitor module w,
which produces high-voltage pulses to all of
the burner ignitors x. The pulses cause a
spark y to occur between the burner ignitor
and the grounded burner cap z, which ignites
the gas and air mixture at the burner head, and
produces a flame.

IGNITOR SYSTEM OVERVIEW
This gas range uses two Carborundum ignitors to provide a source for igniting gas from
the bake and broil burners. Norton ignitors
were previously used in the Whirlpool gas
ranges, and both of these ignitors operate the
same way. The only differences are in the
design (see the illustrations), and in the current ratings.
Carborundum Ignitor
2.5 - 3.0 Amps
IGNITOR SYSTEM OPERATION
The oven ignitor system in these Whirlpool
gas ranges has the following three main components, and is wired in a series-parallel circuit (see the illustration below):
1. An Electronic Oven Control (EOC).
2. Two Carborundum Ignitors (Bake &
Broil).
3. Dual Gas Safety Valve.

BAKE IGNITOR
A Carborundum ignitor uses a round design,
and limits the operating current flow to between 2.5 and 3.0 amperes.
A Norton ignitor uses a rectangular design,
and limits the operating current flow to between 3.2 and 3.6 amperes.
Norton Ignitor
3.2 - 3.6 Amps
All of the self-clean gas ranges use these
components. When the EOC is set to the bake
or broil mode and a temperature is selected,
the relay on the EOC closes, and provides
power to the ignitor. With power applied, current flows through the ignitor circuit, and the
ignitor begins to heat and glow.
