Operation of the Burners
• Press in on the knob and turn it counter-clockwise to
the HI setting on the knob.
• The igniter for the selected burner clicks and sparks.
• After burner ignition, the igniter stops clicking.
• Rotate the knob to any flame setting between HI and
SIM.
• The blue signal light, between the burner knobs, will
light when adjacent burners are lit. The light will remain
on until the adjacent burners are turned off.
BTU for Standard Burners
• HI is equivalent to 18,000 BTU
using Propane).
• SIM is equivalent to 2,100 BTU
HR (15,000 BTU / HR
HR
BTU for ExtraLow ® Burner
• HI is equivalent to 18,000 BTU HR (15,000 BTU / HR
using Propane).
• SIM is equivalent to 3,000 BTU / HR
• XLO ® is equivalent to 370 BTU / HR
ExtraLow ® Burners
The controls for the two left burners, front and rear, have
flame settings even lower than the standard SIM settings.
Figure 14: 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 offand 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
SlM 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 SlM.
• 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 @burners when the igniters are
sparking.
