Dual radiant surface elements 
(some models)
Symbols on the backguard are used to indicate which coil 
of the dual radiant element will heat. The   
indicates the inner coil only. The  
 symbol indicates 
both inner and outer coils will heat.
To operate a dual radiant element:
1. Place correctly sized cookware on dual radiant surface 
2. Push in and turn the surface control knob clockwise to 
begin heating both the inner and outer portions of the 
dual element. If only the inner heating portion is 
needed like for smaller cookware, push in and turn the 
knob counter-clockwise to start.
3. When cooking is complete, turn the dual radiant 
surface element OFF before removing the cookware.
Start most cooking operations on a higher setting and then 
turn to a lower setting to finish cooking. The surface control 
knobs do not have to be set exactly on a particular mark. 
Use the marks as a guide and adjust the control knob as 
needed.  A glowing red surface heating area extending 
beyond the bottom edge of the cookware indicates the 
cookware is too small for the surface heating area.
You may switch from either element setting at any time 
during cooking.  See Suggested radiant surface element 
settings table
 on previous page.
Keep warm 
(some models)
The purpose of the keep warm zone is to keep hot cooked 
foods at serving temperature. Use the  keep warm feature 
to keep cooked foods hot such as; vegetables, gravies, 
casseroles, soups, stews, breads, pastries and oven-safe 
dinner plates.
Always start with hot food. It is not recommended to heat 
cold food on the keep warm zone. All food placed on the 
warming zone should be covered with a lid to maintain 
For best results, when warming pastries or breads, the 
cover should have an opening to allow moisture to escape. 
Do not use plastic wrap to cover food. Plastic may melt 
onto the surface and be very difficult to clean. 
Use only 
dishware, utensils and cookware recommended for oven 
and cooktop use on the keep warm zone.
Setting the keep warm control
1. Push in either direction and turn the knob. The 
temperatures are approximate, and are designated by 
HI and LO. However, the control can be set at any 
position between HI and LO for different levels of 
2. When ready to serve, turn the control to OFF. The keep 
warm zone will remain warm until the indicator light 
Radiant surface elements may appear to 
have cooled after they have been turned off. 
The glass surface may still be hot and burns 
may occur if the glass surface is touched 
before it has cooled sufficiently.
Do not place plastic items such as salt and 
pepper shakers, spoon holders or plastic 
wrappings on top of the range when it is in 
use. These items could melt or ignite. 
Potholders, towels or wooden spoons could 
catch fire if placed too close to the surface 
Do not allow aluminum foil, or ANY material 
that can melt to make contact with the 
ceramic glass cooktop. If these items melt on 
the cooktop, they will damage the ceramic
