Burners
The controls for the two left burners, front and rear, have flame settings even lower
than the standard SIM settings.
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 Burner
XLO, the very lowest setting, is achieved by cycling the flame ON for approxi-
mately 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.
The number and dash 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, Page 21
through Page 23, with the flame on longer at the #4 setting than on #1 setting.
