Operation Of The Burners - Thermador Professional PRO-HARMONY PRG30 Manual De Uso Y Cuidado

Operation of the Burners

• Press in on the knob and turn it counter-clockwise to
the setting on the knob.
• The igniter for the selected sealed 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 / HR (15,000 BTU/HR
using Propane).
• SIM is equivalent to 2,100 BTU / HR.
BTU for ExtraLow® Burners
• 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 375 BTU / HR when the control
knob is adjusted to the lowest setting in the ExtraLow
range.
The controls for the two left burners, front and rear, have
flame settings even lower than the standard SIM settings.
ExtraLow ®
Range
Figure 11: 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.

Setting Indicator
Operation of the ExtraLow Burners
• XLO, the very lowest setting, is achieved by cycling the
flame ON for approximately 7 seconds and OFF for 53
seconds of each minute.
• When the knob is rotated just beyond the SIM setting,
the flame will cycle ON for approximately 54 seconds
and OFF for 6 seconds of each minute.
• To vary the amount of low heat, 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.
