RADIANT HEATING ELEMENT SYSTEMS
Heating Elements: The radiant heating element consists of a resistance
ribbon attached to microporous insulation with molded ceramic fiber walls
in a corrosion-protected metal tray.
The Heating Elements come in four sizes:
Heating Element
• 6" – 240 Volt, 1500 Watts
• 9" – 240 Volt, 3000 Watts (Dual 6" and 9")
Micro Porous
• 6" – 240 Volt, 120 Watts

HOT SURFACE INDICATOR LIGHT
When glass temperature reaches 150°F, the hot surface indicator light is activated
to alert consumer that glass surface is too hot to touch. The hot surface indicator
light is turned on by an additional set of contacts within the temperature limiter.
NOTE: Installation information for reference
only. See Installation Instructions shipped
with product for complete details and before
attempting to install. Anti-tip bracket must be
attached to the floor or wall to hold either
right or left rear leg leveler. Make sure leg
leveler reengages the bracket when 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 as soon as glass temperature reaches 150°F. The HOT LIGHT
will remain on until the glass surface above the heating unit has cooled below 150°F
(even after surface unit switch has been turned off).
2. Detects when glass temperature above a unit has exceeded its limit of approximately
1031°F and disconnects power to that unit. When 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 and right-front elements have two cooking zones:
• To use the large 9" cooking area or bridge, push to turn the control knob clockwise to
desired setting.
• To use the small 6" or 8" cooking area, push to turn the control knob counterclockwise
to 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 your selected control setting.
L1
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.
4a • 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

COMPONENT COMPARTMENT AIRFLOW
Surface Unit
The oven uses a fan for cooling the components. Air is pulled in by the fan
blades and circulated in the component compartment. The air is exhausted
through louvers below the control panel and out the slots above the door.
DOOR ASSEMBLIES:
The doors can be separated into two assemblies: (1) Outer assembly which
consists of handle, vent trim, outer glass, bottom trim and frame; (2) Inner
assembly which consists of inner panel, gasket, glass panels and insulation.
The assemblies are held together by 2 screws on each side, along with 4
screws across the bottom.
CAUTION: Care must be taken when mounting door handle not to overtighten
handle screws. Overtightening screws can damage handle. Hand-tighten
screws (do not use electric driver). Make sure handle fits snuggly to door
panel.
SELF-CLEAN DOOR GASKET:
The door gasket is attached to the frame
front.
1. Locate spring clip at center of gasket and insert in hole on frame front.
2. Install gasket by bending at 90° beside clip and rocking into hole.
3. Tuck loose ends into slot at the bottom of frame front.
REMOVABLE OVEN DOOR
The door is very heavy. Be careful when removing
and lifting the door. Do not lift the door by the handle.
To Remove:

• Clear/Off – Audible tone and display shows time of day.
• Probe – Audible tone and response if meat probe is plugged in.
• Numerical Pads – Audible tone. Can only be used after another function has been
selected.
