SECTION FOUR: USING THE COOKTOP
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
seconds of each minute.
• When the knob is set just
below 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 quantity,
the control can be set
anywhere within the LO and
XLO range marked on the
knob.

ExtraLow Settings
• The number and
designations, shown in the
drawing, are for reference only.
Numbers do not actually
appear on the knob. The
number indicates the position
of the flame setting as
represented on the cooking
chart, Pages 17 and 18, with
the flame on longer at the #4
setting than on #1 setting.
ExtraLow Techniques
• The type and quantity of food
affects which setting to use.
• The pan selected affects the
setting. Its size, type, material,
and whether a lid is used, all
affect the consistency of the
cooking temperature.
• 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 temperature
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
occasionally while simmering.
This is especially important
when simmering for several
hours, such as for a homemade
spaghetti sauce or beans.
• When lowering the flame
setting, 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.
dash
• 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.
Each burner has its own electronic
igniter that sparks when the burner
is turned on. 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. Do not touch the burners
when the igniters are sparking.
If a burner fails to ignite, refer to
the section on Page 43, "Before
Calling for Service."
