ExtraLow Techniques
• The type and quantity of food
affects which setting to use.
• The pan selected affects the
setting. Its size, type, mate-
rial, and whether a lid is used,
all affect the consistency of
the cooking temperature.
Operation of the ExtraLow
Burners
• XLO, the very lowest setting,
is achieved by cycling the
flame ON for approximately 8
seconds and OFF for 52 sec-
onds of each minute.
• When the knob is set just be-
low the LO setting, the flame
will cycle ON for approximately
52 seconds and OFF for 8
seconds of each minute.
• To vary the amount of low
heat to suit the food and quan-
tity, the control can be set any-
where within the LO and XLO
range marked on the knob.
• The number and dash desig-
nations, shown in the draw-
ing, are for reference only.
Numbers do not actually ap-
pear on the knob. The num-
ber indicates the position of
the flame setting as repre-
sented on the cooking recom-
mendations, Pages 14 and 15,
with #4 being hotter than #1.

Components
Each burner has its own
electronic igniter that sparks
when the burner is turned on. Do
not touch the burners when
the igniters are sparking. Each
burner should light in 4 seconds
or less. If a burner does not light,
check to see that the cap is
positioned correctly on the base.
If a burner fails to ignite, refer to
the section on Page 30 “Before
Calling for Service.”

• To maintain a low or simmer
heat, bring food to a rolling
boil. Stir well, then cover the
pan and lower the heat to a
setting just below LO.
• Check periodically to see if
the control knob should be
turned to another setting.
• If an over-size pan is used, the
simmer action may occur
mainly in the center of the
pan. To equalize the tempera-
ture throughout the food, stir
the food around the outer
edges of the pan into the food
in the center.
• It is normal to stir food occa-
sionally while simmering. This
is especially important when
simmering for several hours,
such as for a homemade spa-
ghetti sauce or beans.
• When lowering the flame set-
ting, adjust it in small steps.
• If the setting is too low to hold
a simmer, bring the food back
to a boil before re-setting to a
higher heat.
• It is normal not to see simmer
bubbles immediately after the
food has been stirred.
• There may be bubbling when
the flame cycles ON and no
bubbles when the flame is
OFF. Even when the flame is
OFF, there will be steam and
a slight quiver on the liquid’s
surface.
