BTU for Standard Burners • HI is equivalent to 15,000 BTU / HR (13,000 BTU/HR using Propane). • SIM is equivalent to 2,100 BTU / HR. BTU Output for ExtraLow® Burner • HI is equivalent to 15,000 BTU / HR (13,000 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. Setting Indicator ExtraLow® Range Figure 4: 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 Burner • 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. • 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. 1 2 3 4 Figure 5: ExtraLow Settings Page 15
