Yournew cooktophas a halogen/radiant glass ceramic
cooktop.If yOLIareused to cooking with gas burners
or electric surface units, you will notice some
differenceswhen you use the halogetiradiant cooktop.
The best types of cookware to use, plus heat-up and
cool-downtimes, depend uponthe type of burneror
surface unit you have.
The followingchart will help you to understandthe
differencesb;tween halogen/radiantcooktops and any
other type of cooktop you may have used in the past.

NOTE: A slightodor is normal when a new cooktop
is used for the first time. It iscaused by the heating of
new parts and insulating materials and will disappear
in a shorttime.
When a surface unit is turned on, coilsbeneath the
surfaceunit radiate heat through the glass to the
cookware. The red glow of the coils will be visible
throughthe glass. It will take the surface unit a few
lmomentsto heat up. Thecoil cycles on and off to
maintainyoLlrselected control ~etting.With poor
cookware, you wi~lsee frequent cycling of the unit
off and on. Good, flat cookware will minimize
the cycling.

Even after the surface units are turned off, the glass
ceramic cooktopretains enough heat to continue
cooking.To avoid overcooking,remove pansfrom
the surface units when the food is cooked. Avoid
placinganything on the surface unit until it has
cooled completely.
The Hot Surface Lights will stay lit until the cooktop
is safe to touch. It is not unusual for the lights to stay
lit for 30 minutes.

sandwich bottom combines the benefits of stainless
steel (appearance, durability and stability)with the
advantagesof aluminumor copper(heat conduction,
even heatdistribution).
Alun]inum:heavy ~veighrrecommended
Good conductivity.Aluminum residues sometimes
appear as scratcheson the cooktop, but can be
removed if cleaned immediately.Because of its
low melting point, thin weight aluminum shouldnot
be used.
Porcelai~namel:
Good performance only with a thick, flat, smooth
bottom. Avoid boiling dry, as porcelain can melt and
fuse to the surface.
Howtocheck PanPerformance
Use of correct cookware can affect the cooking
formance and cleaning of your cooktop.
correct cookware reduces the temperature of
ooktop surface and minimizes the chance of
overs burning onto the cooktop.
must use pans with perfectly flat bottoms.
Some pans may have curved or rounded bottoms or
may be warped. If you are unsure of the fiatness of
your pans you may do this quick test.
Turn yoLIrpan upside
down on the countertop,
place :1ruler flat against
the pan surface. The
bottomof the pan and the
straightedge of the ruler
shouldfit
flLIshagainst each other all the way across.
Turn the ruler a full 360 degrees, checking for any
space between the ruIer and the bottom of the pan.
I’))l!l
b~
Lti
Copper
Bottom: heavy vveightrecomnzeizded
Good performance, but copper may leave residue
if pot is allowed to boildry. Overheated metal can
bond to glass cooktops. If pot boils dry,leaving a
residue on the glass, clean immediately.
Glass-ceramic:Ltsable,butnot recommended
Poor performance. May scratch the surface.
Stoneware: usable,but rxotrecommetzded
Poor performance. May scratch the surface.
Cast Iron: usable, but ]zotrecommended
Poor performance. May scratch the surface.
Pans with rounded, curved, ridged or warped bottoms
are not recommended.
Another simple test to determineeven heat distribution
acrossthe cookware bottom isto put one inchof water
in the pan. Bring the water to aboil and observe the
locationof bubbles as the water starts to boil.
Good flat cookware willhave an even distribution of
bubblesover the bottomsurfacearea of the pan.
Bubbleslocalizedin only a portionof the bottom
indicateuneven contact of the pan to the surface unit,
uneven heat transferor an unsuitablepan.
Use pansthat match the diameter of the surface
unit. Cooking perfollnance will not be as good if
the cookware is either smaller or larger than the
surface unit.

observetheFollowingPointsincanning
1. Be sure the canner fitsover the center of the

allowthe canner to be centered on the surface unit,
use smaller diameter pots for good canning results.
2. Fla~-bottomedcannersmust be used. Do not use

HOWEVER, DO NOT USE LARGE DIAMETER
CANNERS OR OTHER LARGE DIAMETER POTS
FOR FRYING OR BOILING FOODS OTHER

all typesof frying—cook at temperatures much higher
than boilingwater. Such temperaturescould
eventuallyharm the glass cooktop surfaces.
3. When canning, use recipes and procedures from

General Information:
As the Cook TOPCleaning Creme cleans, it
leaves a protectivecoatin~ on the cooktop surface.
This coating helps to prevent build-up of mineral
deposits (water spots) and will make future cleaning
easier.Dishwashing detergents remove this protective
coating and therefore make the cooktop more
susceptibleto staining.
