DISCONNECT POWER BEFORE SERVICING
IMPORTANT: RECONNECT ALL GROUNDING DEVICES. All parts of this appliance
capable of conducting electrical current are grounded. If grounding wires, screws,
straps, clips, nuts or washers used to complete a path to ground are removed for
service, they must be returned to their original position and properly fastened.

RADIANT HEATING ELEMENT SYSTEMS

Heating Elements: The radiant heating element consists of a spiral-wound resistance
wire attached to microporous insulation with molded ceramic fiber walls in a corrosion-
protected metal tray.
The Heating Elements come in various sizes:
• 6" – 240 Volt, 1500 Watts
• 12" – 240 Volt, (1050, 1950, 3000 Watts)
(Triple 6", 9" and 12")
• Warmer – 240 Volt, 120 Watts
• 9" – 240 Volt, (1400, 3000 Watts)
(Double 6" and 9")

HOT SURFACE INDICATOR LIGHT

The Hot Surface Indicator Lights are now under the cooktop. The Hot Surface Indicator
Light will turn on when the surface unit switch is turned on. The Indicator Light will
remain on through an additional set of contacts on the limiter as long as the glass
temperature exceeds 150°F.
NOTE: Installation information is
for reference only. See Installation
Instructions shipped with the product
for complete details and before
attempting to install.
Brackets should be attached to the floor
and wall to hold either the right or left
rear leg leveler. Make sure the leg leveler
reengages the bracket when the range
is moved for any reason.

TEMPERATURE LIMIT/HOT LIGHT SWITCH

The Temperature Limit/Hot Light Switch performs two functions:
1. Turns on HOT LIGHT when the Surface Unit Switch is turned on. The hot light will
remain on until the glass surface above the heating unit has cooled below 150°F
(even after the surface unit switch has been turned off).
2. Detects when the glass temperature above a unit has exceeded its limit
of approximately 1031°F and disconnects power to that unit. When the glass
temperature cools below 1031°F, the unit will turn back on. The temperature limit/hot
light switch cannot be calibrated.

DUAL CIRCUIT CONTROL

The left-front element may have two cooking zones:
• To use the large cooking area or bridge, push to turn
the control knob clockwise to the desired setting.
• To use the small cooking area, push to turn the control
knob counterclockwise to the desired setting.
When a cooking zone is activated, coils beneath the zone
radiate heat through the glass cooktop to the utensil. The
red glow of the coils will be visible through the glass. It will
take the cooking zone on the glass surface a few moments
to heat up. The coil cycles on and off to maintain the
selected setting.

TRIPLE CIRCUIT CONTROL

The right-front element may have three cooking zones:
• To use the large cooking zone, push to turn the control
clockwise to the desired setting.
• To use the small cooking zone, push to turn the control
knob counterclockwise to the desired setting.
• To use the medium cooking zone, push to turn the control
knob clockwise or counterclockwise to the desired setting
between the large and small setting areas.
When a cooking zone is activated, coils beneath the zone
radiate heat through the glass cooktop to the utensil. The
red glow of the coils will be visible through the glass. It will
take the cooking zone on the glass surface a few moments
to heat up. The coil cycles on and off to maintain the
selected setting.
