Figure 13: ExtraLow Burner Control Knob
The drawing shows that the control knob has an additional
range between the SIM and XLO settings. When the knob
is set within this range, the flame cycles off and on. By
varying the length of time the flame is off and on, the heat is
reduced even further to cook delicate foods. For example,
these very low settings are suitable for simmering and
poaching, melting chocolate and butter, holding cooked
foods at temperatures without scorching or burning, etc.
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 SIM 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
SIM and XLO range marked on the knob.
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 SIM.
• 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.
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.
CAUTION:
DO NOT touch the STAR
sparking.
