Check to be sure the burner you turned on is
the one you want to use.
After the burner lights, turn the knob in
eitherdirection to adjust the flame size. To turn a
burner off, turn the knob clockwise as far as it will
go, to the OFF position.
The indicator lamp in the bezel for each knob
verifies the burner is ON.
Caution: Do not operate a burner for an extended
period of time without cookware on the grate. The
finish on the grate may chip without cookware to
absorb the heat.
Selecting Flame Size
All 5 burners on your cooktop have 2 rows of
flames. These dual-flame burners have an upper
ring of main burner ports which produce the main
flame for high-heat cooking from the HI knob
setting to the LO knob setting.
The bottom simmer flame is used for simmer
heat cooking operations such as melting choco-
late, holding food at serving temperature, and
simmering.
Both MAIN and SIMMER flames are lit when the
knob is between HI and LO. Only the simmer
flame is lit when the knob is in the SIMMER
position.
Burner Adjustment
There is no adjustment on this burner. See
Burner Cleaning.
Burner Cleaning
The slits in the burner rings of the cooktop must
be kept clean at all times for an even, unhampered

burner ring subassemblies, remember their size

after cleaning for proper burner operation.
