Thermador PRD36, PRD48, PRD30 Electronic Single Point Ignition, Operation of the ExtraLow Burners

Section Four: USING THE COOKTOP

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 LO 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 LO and XLO range marked on the knob.

ExtraLow Settings

•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, pages 17 and 18, with the flame on longer at the #4 setting than on #1 setting.

•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 LO.

•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.

Components

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 burners when the igniters are sparking.

If a burner fails to ignite, refer to the section on Page 40, “Before Calling for Service.”

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.
