The following information will help you choose cookware which will give good performance on glass cooktops.

SURFACE

COOKING

Never cook directly on the glass. Always use cookware.

OFF CENTER

Always place the pan in the center of the surface unit you are cooking on.

About the radiant surface units…

The radiant cooktop features heating units beneath a smooth glass surface.

NOTE: A slight odor is normal when a new cooktop is used for the first time. It is caused by the heating of new parts and insulating materials and will disappear in a short time.

NOTE: On models with light-colored glass cooktops, it is normal for the cooking zones to change color when hot or cooling down. This is temporary and will disappear as the glass cools to room temperature.

The surface unit will cycle on and off to maintain your selected control setting.

It is safe to place hot cookware on the glass surface even when the cooktop is cool.

Even after the surface units are turned off, the glass cooktop retains enough heat to continue cooking. To avoid overcooking, remove pans from the surface units when the food is cooked. Avoid placing anything on the surface unit until it has cooled completely.

DRAGGING

Do not slide cookware across the cooktop because it can scratch the glass—the glass is scratch-resistant, not scratchproof.

Water stains (mineral deposits) are removable using the cleaning cream or full-strength white vinegar.

Use of window cleaner may leave an iridescent film on the cooktop. The cleaning cream will remove this discoloration.

Don’t store heavy items above the cooktop. If they drop onto the cooktop, they can cause damage.

Do not use the surface as a cutting board

Selecting types of cookware.

SafetyInstructions Operating Instructions Care and Cleaning

Check pans for flat bottoms by using a straight edge.

Pans with rounded, curved, ridged or warped bottoms are not recommended.

Stainless Steel:

recommended

Aluminum:

heavy weight recommended

Good conductivity. Aluminum residues sometimes appear as scratches on the cooktop, but can be removed if cleaned immediately. Because of its low melting point, thin weight aluminum should not be used.

Copper Bottom:

recommended

Copper may leave residues which can appear as scratches. The residues can be removed, as long as the cooktop is cleaned immediately. However, do not let these pots boil dry. Overheated metal can bond to glass cooktops. An overheated copper bottom pot will leave a residue that will permanently stain the cooktop if not removed immediately.

Porcelain Enamel-Covered Cast Iron:

recommended

As long as the cookware is covered completely with porcelain enamel, this cookware is recommended. Caution is recommended for cast iron cookware that is not completely covered with smooth porcelain enamel, since it may scratch the glass ceramic cooktop.

Glass-Ceramic:

usable, but not recommended

Poor performance. May scratch the surface.

Stoneware:

usable, but not recommended

Poor performance. May scratch the surface.
