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.
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.
• The number and dash
designations, shown in the
drawing, are for reference only.
They 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 #4 being hotter than #1.

Components
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.”

IGNITER
• 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.
• 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.
