USING THE COOKTOP
Sealed Burners
Sealed Star_ Brass
Burner Base
The cooktop features four or six
gas surface burners; each rated
at 15,000 BTU/HR using natural
gas (13,000 BTU/HR using
propane). The burners are sealed
to the stainless steel top frame to
prevent liquid spills from
accumulating below the top
surface, making it easier to clean.
On all models, the two left burners
have the exclusive ExtraLow
feature, the remaining burners are
standard. Each burner has its own
control knob.
CONTROL KNOBS
The control knobs for two sealed
gas burners, one in front and one
in the rear, are located directly _n
front of and below the pair of
burners on the control panel.

Range
ExtraLow® Burner
Control Knob
The drawing shows that the
control knob has an additional
range between the LO 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.
