READ ALL INSTRUCTIONS BEFORE USING YOUR COOKTOP  
• Before servicing or cleaning unit, switch power off at  
servicepanelandlockservicepaneltopreventpower  
from being switched on accidentally.  
WARNING: IF THE INFORMATION IN THIS  
MANUAL IS NOT FOLLOWED EXACTLY, A FIRE OR  
EXPLOSION MAY RESULT CAUSING PROPERTY  
DAMAGE, PERSONAL INJURY OR DEATH.  
• Do not cook on a cooktop in which the glass top has  
broken. If the cooktop glass should break, do not use  
it or attempt to clean or fix it. Cleaning solutions and  
spill-overs may penetrate the broken cooktop and  
createariskofelectricshock. Turnoffelectriccircuit  
to the cooktop and call an authorized service agency  
immediately.  
WARNING: TO REDUCE THE RISK OF FIRE,  
ELECTRIC SHOCK, OR INJURY TO PERSONS,  
OBSERVE THE FOLLOWING:  
• DO NOT USE WATER, including wet dishcloths or  
towels - a violent steam explosion will result.  
• WARNING:DONOTSTOREITEMSOFINTEREST  
TO CHILDREN ABOVE THE COOKTOP OR AT  
THE BACK OF IT. IF CHILDREN CLIMB ONTO  
THE COOKTOP TO REACH THESE ITEMS, THEY  
COULD BE SERIOUSLY INJURED.  
• SMOTHER FLAMES from a grease fire with a close-  
fitting lid, cookie sheet or other metal tray. Turn off  
the gas burners or the electric elements. BE CARE-  
FUL TO PREVENT BURNS. If the flames do not go  
out immediately EVACUATE AND CALL THE FIRE  
DEPARTMENT.  
• Children should not be left alone or unattended in an  
area where appliances are in use. They should never  
be allowed to sit or stand on any part of appliance.  
• Use baking soda to SMOTHER FLAMES from other  
type food fires. Never use water on cooking fires.  
WARNING: Do not store flammable materials on or  
near the cooktop.  
• NEVER PICK UP A FLAMING PAN - You may be  
burned.  
• When using the cooktop, do not touch the hot  
cooking area or the immediate surrounding area.  
Even though dark in color, these areas may be hot.  
Areas adjacent to the elements may become hot  
enough to cause burns.  
• TURN OFF THE VENTILATOR in case fire or when  
"flaming" liquor or other spirits. The blower could  
spread the flames.  
• ALWAYS HAVE A WORKING SMOKE DETEC-  
TOR NEAR THE KITCHEN.  
• Never let clothing, pot holders, or other flammable  
materials come in contact with the burners, burner  
grates or cooking area until they are cool to the  
touch.  
• USE AN EXTINGUISHER ONLY IF:  
1. You know you have a Class ABC extinguisher, and  
you already know how to operate it.  
• Use only dry pot holders. Moist or damp pot holders  
on hot surfaces may cause burns from steam. Do not  
use a towel or other bulky cloth in place of pot  
holders. Do not let pot holders touch hot cooking  
areas.  
2. The fire is small and contained in the area where it  
started.  
3. The fire department is being called.  
4. You can fight fire with your back to an exit.  
• Always use utensils that have flat bottoms and that  
are large enough to cover the whole cooking area.  
The use of a utensil smaller than the size of the  
cooking area will expose a portion of the heated area  
to direct contact with the user which could result in  
burns.  
WARNING:TOREDUCETHERISKOFFIRE,ELEC-  
TRIC SHOCK, OR INJURY TO PERSONS, OB-  
SERVE THE FOLLOWING:

IMPORTANT SAFETY INSTRUCTIONS  
L
L
• Hold the handle of the pan to prevent movement of  
the utensil when stirring or turning food. Turn  
handles of utensils inward so that they do not extend  
over adjacent work areas, cooking areas, or the edge  
of the cooktop. This will help prevent hot food spills.  
• The cooktop is factory assembled for natural gas. It  
should be correctly adjusted by a qualified service  
person or installer for the type of gas with which it is  
used. (See Page 1 for propane gas.)  
• For personal safety, wear proper apparel. Loose  
fitting garments or hanging sleeves should never be  
worn while cooking.  
• CAUTION: The cooktop is for cooking. Never use  
it to warm or heat a room.  
• In the event that personal clothing catches fire,  
DROP AND ROLL IMMEDIATELY to extinguish  
flames.  
• Be sure your appliance is properly installed and  
grounded by a qualified servicer in accordance with  
theInstallationInstructionsprovidedwiththecooktop.  
• Do not use aluminum foil to line any part of the  
cooktop. Improper use of a foil liner could result in  
a shock, fire hazard or it could obstruct the flow of  
combustion and ventilation air. Foil is an excellent  
heat insulator and heat will be trapped beneath it.  
This will upset the cooking performance and can  
damage the cooktop finish.  
• Do not repair or replace any part of the appliance  
unless specifically recommended in this manual. All  
other servicing should be referred to a qualified  
servicer.  
• Use high heat settings on the cooktop only when  
necessary. Use low to medium settings to heat oil  
slowly.  
• Do not heat unopened food containers; a buildup of  
pressure may cause the container to burst.  
• Other than the use of metal pans, only certain types  
of glass, heat-proof glass ceramic, ceramic, earthen-  
ware,orotherglazedutensilsaresuitableforcooktop  
use. These types of utensils may break with sudden  
temperature changes. Use only on low or medium  
heat settings according to the utensil manufacturer’s  
directions.  
• Never leave the burners unattended when using high  
flame settings. Boilovers cause smoking, and greasy  
spillovers that may ignite. More importantly, if the  
flame is smothered, unburned gas will be coming into  
the room. See “What To Do If You Smell Gas”, Page  
1.  
• During cooking, set the burner control so that the  
flame heats only the bottom of the pan and does not  
extend beyond the edge of the pan.  
• Clean the cooktop with caution. If the soil must be  
removed while the cooktop is hot, clean the hot top  
with the metal razor blade scraper only. Do not use  
a wet sponge or cloth while it is hot. Some cleaners  
produce noxious fumes if applied to a hot surface.  
• If the cooktop is near a window, be certain the  
curtains do not blow over or near the burners; they  
could catch on fire.  
• Clean the ventilation system above or behind the  
cooktop frequently, so that grease from the cooking  
vapors does not accumulate on the filters, fan, intake,  
or hood.  
• Take care that drafts, like those from fans or forced  
air vents, do not blow flammable material toward the  
flames or push the flames so that they extend beyond  
the edges of the utensil.  
• For proper lighting and performance of the burners,  
keep the igniters clean. It is necessary to clean these  
when there is a boil over, or when the burner does  
notlighteventhoughtheelectronicignitersclick. See  
Page 18.  
• In the event a burner goes out and gas escapes, turn  
OFF all the controls and open a window or a door.  
Do not attempt to use the cooktop until the gas has  
had time to dissipate. Wait at least 5 minutes before  
using the cooktop.

ELECTRIC COOKTOP OPERATION  
BEFORE USING THE COOKTOP FOR THE  
FIRST TIME:  
ELEMENTS  
When either element is turned on the "ON" signal light  
turns red; when both elements are turned off, the  
“ON” signal light goes out.  
• Remove all packing materials and literature from the  
cooktop surface. Read all safety precautions and  
care & use information prior to operating.  
outer  
inner  
• While cool, wipe with a clean, damp sponge and dry.  
• Apply the Cooktop Cleaning Creme® packaged  
with the cooktop. Buff with a clean cloth. This helps  
protect the surface and makes cleanup easier. See  
Page 16 for daily care instructions.  
• There may be a slight odor during the first several  
uses; this is normal and will disappear.  
Dual Radiant Elements (Models CD365 & CD456)  
• Optimum cooking results depend on the proper  
cookware being selected and used. See Pages 12-13.  
This type of electric element has two cooking sizes.  
Select either the small inner element or both the inner  
and outer elements, (dual) depending of the base size of  
your pan.  
• The cooking surface will hold the heat and remain  
hot up to 25 or 30 minutes after the elements have  
been turned off. See Hot Surface Indicator lights on  
Page 9.  
TEMPERATURE LIMITERS  
PrecautionsforLongLifeandGoodAppearance  
of the Surface:  
Each radiant heating element has its own sensor to  
protect the glass cooking surface from extreme high  
temperatures. The limiters will operate automatically  
bycyclingtheelementoffregardlessoftheknobsetting.  
• Regular, daily care using the Cooktop Cleaning  
Creme will protect the surface and make it easier to  
remove food soil and water spots.  
Although cycling is normal, any one of the following  
conditions can activate the limiter and cause it to cycle  
on and off more than usual:  
• The glass ceramic cooking surface is a durable mate-  
rial that is resistant to impact but is not unbreakable  
if a pan or other object is dropped on it.  
• Thebaseofthepanisnotmakingfullcontactwiththe  
heating surface (due to a warped or uneven base).  
• Do not use aluminum foil directly on the glass; it will  
melt and permanently damage the glass surface.  
• The pan base is too small for the size of the element.  
• The pan has boiled dry.  
• Do not allow plastic, paper, or cloth to come in  
contact with the hot glass surface; these items can  
melt or burn and can damage the glass surface.  
• The material or shape of the pan is slow to transfer  
the heat.  
• Do not allow pans to boil dry. This can permanently  
damage the pan, element and/or the cooktop.  
• No pan has been placed on the element.  
• Use only flat bottom pans. (See Page 12).  
• Never cook food directly on the glass.  
• Do not use the glass surface as a cutting board.  
• Do not slide cookware across the cooking surface;  
itmayscratchtheglass. Evencookwarewithsmooth  
bases may scratch, if grit gets between the pan and  
the surface.

ELECTRIC COOKTOP OPERATION  
RETAINED HEAT  
CONTROL KNOBS  
The glass cooking surface retains heat and stays hot  
after the element(s) have been turned off. The retained  
heat may be used to hold foods at serving temperatures  
for a short time.  
The placement of each knob corresponds to the place-  
ment of the heating element that it controls. To turn  
on any element, PUSH DOWN on the knob and TURN  
in either direction to the desired heat setting.  
There are an infinite number of heat settings  
between the LO and HI positions. Detents (fixed  
positions) are found at LO and HI to define minimum  
and maximum heat settings. The LO setting provides a  
very low heat for simmering foods such as spaghetti  
sauce and cooking Hollandaise sauce. With the option  
ofusingeithergasandelectric,youcanmoveapanfrom  
gas to electric (LO) for an even lower heat setting.

The element “ON” signal light glows whenever any  
elementisturnedon. Thelightremainslituntilallofthe  
elements are turned off.  
The “ON” light is located on the right side and below  
the control knobs.  
HOT SURFACE INDICATOR LIGHTS  
When the elements are turned on, a red glow can be  
seen through the glass. The elements cycle on and off  
to keep the selected heat setting. Poor cookware  
causes the element to cycle on and off more often. (See  
Temperature Limiters on Page 8).  
Whenever a cooking surface is too hot to touch, an  
indicator light will turn on automatically in the area  
marked Hot Surface. The light remains on until the  
cooking area has cooled to a safe-to-touch tempera-  
ture. There is one Hot Surface Indicator light for each  
electric heating element.  
To turn ON the small, inner element only, press  
down on the control knob and turn it clockwise to a  
heat setting.  
If a Hot Surface Indicator light is on, use caution when  
working or cleaning around the cooktop.  
To turn ON both inner and outer elements  
together, press down on the control knob and turn it  
counterclockwise to a heat setting.

the burner up slightly.  
The XLO setting on the right front and right rear  
burners (CGX304), and the center front and center  
rear burners (CGX365 and CGX456) are designed to  
provide flame settings which enable you to simmer,  
poach, melt and hold cooked food at a serving tempera-

PROPER COOKWARE  
CHARACTERISTICS OF A GOOD PAN  
The choice of pans directly affects the cooking speed  
and uniformity. For best results select pans with the  
following features:  
FLAT BASES - Check flatness of pan with a straight  
edge. When pan is hot, the base (pan bottom)  
should rest evenly on the surface without wobbling.  
To check flatness on the electric surface, put one  
inch of water in a pan. Turn control to HI and  
observe the bubble formation in the bottom of the  
pan. Flat pan bases have an even distribution of  
bubbles. Bubbles forming in one or two areas show  
uneven pan contact and uneven heat conduction.  
Balanced Pan  
PAN MATERIAL and WEIGHT - Medium to heavy  
weight metal pans, with copper or aluminum disc  
bottoms, conduct heat well. On the glass surface  
they may leave residues which look like scratches;  
clean immediately to remove. Medium to heavy  
weight pans distribute heat more evenly and resist  
warping. To prevent warping, cool pans slowly so  
they will stay flat.  
Convex (rounded)  
Concave (hollow)  
DIAMETER - The base of the pan should cover or  
match the diameter of the electric element or flame  
size. Pans may overhang the element area no more  
than 1" all around. On a gas burner, the flames  
should hit only the bottom of the pan.  
PLACEMENT-Centerthepanontheburnergrateor  
electric element before turning the unit on.  
SIZE - Use cookware that is large enough to accommo-  
date the amount of food or liquid to eliminate the  
possibility of boilovers and spattering.  
Flame Too Large for Pan Size  
Use Lids that fit Properly  
TIGHT FITTING LID - A lid shortens cooking time  
by holding the heat inside the pan.  
Unbalanced Pan  
Do not use cookware with these characteristics:  
Thin bottom  
Concave bottom when heated  
Convex bottom when heated  
Poor balance (rocks back from weight of handle)  
!
L
CAUTION  
Plastic, paper and cloth can melt or burn  
when in contact with a hot surface or burner grate.  
Do not let these items come in contact with the  
burner grate or electric element cooking surface.  
!
LCAUTION  
Foods packaged in aluminum foil should not  
be placed directly on the glass ceramic surface or  
burner grate for cooking; aluminum foil can melt to  
either surface and cause permanent damage.  
Do not allow pans to boil dry. This can perma-  
nently damage the pan, the element, the burner  
grate, the cooktop glass and/or the burner plate.

PROPER COOKWARE  
Do not use unusually large or warped utensils such as  
canners and stock pots on HI heat for an extended  
period of time. This may cause heat build up which can  
result in damage to the cooktop or the surrounding  
countertop. Once food has reached temperature, turn  
the control setting down to maintain the cooking heat.  
Use canners and stock pots that have a flat bottom and  
extend no more than 2 inches beyond the burner grate.  
Canning Tips:  
An oversize canning pot can be used on the gas burners  
with success following these suggestions:  
Useacannerwithadarkordullfinishtoreduceheat  
reflecting back to the cooktop surface.  
Select a canner with a flat bottom, rather than one  
with a concave, convex or rippled bottom.  
Large or Warped Utensils  
Allow at least 3/8 inch of air space between the  
canner overhang and the cooktop surface.  
Woks and Speciality Pans  
Useonlyaflatbottomwokonelectricheatingelements.  
A round bottom wok can be used on the burners with  
a support ring. The round bottom wok is unstable  
without the ring. Check that the ring does not restrict  
air to the burners causing a yellow flame. See Custom  
Accessories AWOKRING below.  
Use the lowest heat setting possible to maintain a  
boil or pressure.  
Be sure to cover all containers.  
Follow the canning instructions given in a standard  
cookbook or manufacturer’s instructions provided  
with the canning jars.  
Specialty pans such as woks, lobster pots, pressure  
cookers, griddles, French fryers, etc. must meet similar  
design requirements as regular cookware: flat bottom,  
balanced, correct size, and proper cover (if applicable).  
Use care to prevent burns from the large amount of  
steam generated by the canning process.  
Custom Accessories  
Thermador® offers several accessories for use on dual  
or gas burner cooktops.  
Look for canners fitting this description:  
Water Bath Canner: Standard 21 to 22-quart  
canners with an 11 to 12-inch diameter and a 9 to  
11-inch depth.  
AWOKRING-aringdesignedtoholdaroundbottom  
wok. It is custom fitted to the shape of the grate.  
GG1 - a cast aluminum griddle with a non-stick finish  
that spans two burners. It is custom fitted to the grates.  
Pressure Canner: Canners vary in size from 8 to  
22 quarts with 8 to 11-inch bottom diameters and  
a 6-1/2 to 12-inch depth.  
AEGRIDDLE - an anodized aluminum griddle that  
spans two glass ceramic electric elements.

SPECIAL CARE TECHNIQUES  
TYPE OF SOIL  
POSSIBLE SOLUTION  
Failure to remove these soils immediatly can  
permanently damage the surface.  
Dry sugar, sugar syrup, milk or tomato spills.  
Melted plastic film or foil. All these items  
REQUIRE IMMEDIATE REMOVAL. Removeonly  
these types of spills while the surface is hot using the  
razor blade scraper. See Page illustration on page16.  
• Remove pan and turn off the element.  
• Angle the scraper slightly, using care not to gouge or  
scratch the glass. Push soil off the heated area.  
• After the surface has cooled, remove the residue and  
apply the Cooktop Cleaning Creme®.  
• Soften by laying a damp paper towel or sponge on top  
of soil for about 30 minutes.  
• Use non-metal scouring pad such as Dobie® with Soft  
Scrub®, or use the razor blade scraper. Rinse and dry.  
Recondition with Cooktop Cleaning Creme and a  
clean cloth or paper towel.  
Burned-on food soil, dark streaks, and specks  
• Use vinegar or a soapy sponge to remove grease; rinse  
thoroughly and dry. Apply Cooktop Cleaning Creme.  
Greasy spatters  
Metal marks  
• Pans with aluminum, copper or stainless steel bases  
mayleavemarks. Treatimmediately, aftersurfacehas  
cooled, with the Cooktop Cleaning Creme. If this  
does not remove the metal marks, try a mild abrasive  
(Bon Ami®, Soft Scrub®) with a dampened paper  
towel; rinse; and re-apply creme.  
Failure to remove metal marks before the next  
heating makes removal difficult.  
• The minerals in some water can be transferred onto  
the surface and cause stains. Use undiluted white  
vinegar, rinse and dry. Recondition with Cooktop  
Cleaning Creme.  
Hard water spots  
Hot cooking liquids dripped on surface  
Remove boil-overs / stains, before using the cooktop again.  
Surface scratches:  
• Canbereducedbyremovingsand-likegrains/gritsuch  
as salt and seasoning from below the pan.  
Small scratches are to be expected on the glass surface  
, but do not affect cooking. Although scratches are not  
removable, in time they will become smoother and  
much less noticeable with daily use of the Cooktop  
Cleaning Creme.  
• Can be reduced by using pans with bases that are  
smooth,clean,anddrybeforeuse. Userecommended  
Cooktop Cleaning Creme daily on the cooktop.  
CAUTION: Diamond rings will scratch the surface.
