BTU Output for Standard Star® Burners

•HI is equivalent to 18,000 BTU / HR (15,000 BTU / HR using Propane).

•SIM is equivalent to 2,100 BTU / HR.

BTU Output for ExtraLow Star® 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.

BTU Output for POWERBOOSTTM

•XHITM for the POWERBOOSTTM is equivalent to 22,000 BTU / HR (18,000 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.

ExtraLow® Burners

The controls for the two left and two right burners, front and rear, have flame settings even lower than the standard SIM settings (see Figure 10 on Page 12).

Figure 11 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 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.

POWERBOOSTTM

The POWERBOOSTTM, or XHITM, is located at the right-front position of the rangetop. The XHITM is 4,000 BTU greater on its highest setting than any other Star® Burner. It offers the convenience to quickly boil water, sear steaks, stir-fry vegetables, etc. Use of the SIM and XLO® remains the same as the other XLO® Knobs (see Figure 10 on Page 12).
