READ ALL INSTRUCTIONS BEFORE USING YOUR COOKTOP

▲

!

WARNING: IF THE INFORMATION IN THIS
MANUAL IS NOT FOLLOWED EXACTLY, A FIRE OR
EXPLOSION MAY RESULT CAUSING PROPERTY
DAMAGE, PERSONAL INJURY OR DEATH.

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.

• SMOTHER FLAMES from a grease fire with a close­fitting lid, cookie sheet or other metal tray. Turn off
the gas burners or the electric elements. BE CARE­FUL TO PREVENT BURNS. If the flames do not go
out immediately EVACUATE AND CALL THE FIRE
DEPARTMENT.

• Use baking soda to SMOTHER FLAMES from other
type food fires.

• NEVER PICK UP A FLAMING PAN - You may be
burned.

• 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 DETEC­TOR NEAR THE KITCHEN.

• USE AN EXTINGUISHER ONLY IF:

1. You know you have a Class ABC extinguisher, and
you already know how to operate it.

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.

WARNING: TO REDUCE THE RISK OF FIRE, ELEC­TRIC SHOCK, OR INJURY TO PERSONS, OB­SERVE THE FOLLOWING:

• Use this unit only in the manner intended by the
manufacturer. If you have any questions, contact the
manufacturer

Never use water on cooking fires.

• Before servicing or cleaning unit, switch power off at
service panel and lock service panel to prevent power
from being switched on accidentally.

• 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
create a risk of electric shock. Turn off electric circuit
to the cooktop and call an authorized service agency
immediately.

• WARNING: DO NOT STORE ITEMS OF INTEREST
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.

• 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.

WARNING: Do not store flammable materials on or
near the cooktop.

• 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.

• 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 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.

• 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.

• Always use cookware and utensils appropriate for
the type and amount of food being prepared.

IMPORTANT SAFETY INSTRUCTIONS

!

▲

• 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.

• CAUTION: The cooktop is for cooking. Never use
it to warm or heat a room.

• Be sure your appliance is properly installed and
grounded by a qualified servicer in accordance with
the Installation Instructions provided with the cooktop.

• 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.

• Other than the use of metal pans, only certain types
of glass, heat-proof glass ceramic, ceramic, earthen­ware, or other glazed utensils are suitable for cooktop
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.

• 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.

• In the event that personal clothing catches fire,
DROP AND ROLL IMMEDIATELY to extinguish
flames.

• 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 heat unopened food containers; a buildup of
pressure may cause the container to burst.

• 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.

• 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.
produce noxious fumes if applied to a hot surface.

• 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.

• 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
not light even though the electronic igniters click. See
Page 18.

Some cleaners

• 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.

• If the cooktop is near a window, be certain the
curtains do not blow over or near the burners; they
could catch on fire.

• 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.

• 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:

• Remove all packing materials and literature from the
cooktop surface. Read all safety precautions and
care & use information prior to operating.

• 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.

• Optimum cooking results depend on the proper
cookware being selected and used. See Pages 12-13.

• 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.

Precautions for Long Life and Good Appearance
of the Surface:

• Regular, daily care using the Cooktop Cleaning
Creme will protect the surface and make it easier to
remove food soil and water spots.

• The glass ceramic cooking surface is a durable mate­rial that is resistant to impact but is not unbreakable
if a pan or other object is dropped on it.

• Do not use aluminum foil directly on the glass; it will
melt and permanently damage the glass surface.

• 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.

• Do not allow pans to boil dry. This can permanently
damage the pan, element and/or the cooktop.

• Use only flat bottom pans. (See Page 12).

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.

outer

inner

Dual Radiant Elements (Models CD365 & CD456)

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.

TEMPERATURE LIMITERS

Each radiant heating element has its own sensor to
protect the glass cooking surface from extreme high
temperatures. The limiters will operate automatically
by cycling the element off regardless of the knob setting.

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 base of the pan is not making full contact with the
heating surface (due to a warped or uneven base).

• The pan base is too small for the size of the element.

• The pan has boiled dry.

• The material or shape of the pan is slow to transfer
the heat.

• No pan has been placed on the element.

• 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;
it may scratch the glass. Even cookware with smooth
bases may scratch, if grit gets between the pan and
the surface.

Page 8

ELECTRIC COOKTOP OPERATION

CONTROL KNOBS

The placement of each knob corresponds to the place­ment 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
of using either gas and electric, you can move a pan from
gas to electric (LO) for an even lower heat setting.

RETAINED HEAT

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.

Hot Surface Indicator Lights

"ON" Indicator
Light

SIGNAL LIGHTS

Element “ON” Signal Light

The element “ON” signal light glows whenever any
element is turned on. The light remains lit until all of the
elements are turned off.

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).

To turn ON the small, inner element only, press
down on the control knob and turn it

clockwise to a

heat setting.

To turn ON both inner and outer elements
together, press down on the control knob and turn it

counterclockwise to a heat setting.
The element is in the off position when the indicator on

the knob lines up with the word “OFF” and snaps into
place. Align the indicator with the LO position. The dual

●

element symbol

and the inner element symbol ● are

not heat settings.

The “ON” light is located on the right side and below
the control knobs.

HOT SURFACE INDICATOR LIGHTS

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 tempera­ture. There is one Hot Surface Indicator light for each
electric heating element.

If a Hot Surface Indicator light is on, use caution when
working or cleaning around the cooktop.

STANDARD BURNER

(All Models)

All standard burner controls press down to turn and
have an infinite number of heat settings. There are no
fixed positions. Select the appropriate control knob,
press down and turn it counterclockwise to the HI
position (detent) until the burner lights. Adjust the
flame size. Turn off by turning the control clockwise to
OFF.

OFF

• The burner flame will pulse ON and OFF when the
setting is at any position between LO and XLO.

• The length of time the flame is ON and OFF varies.

• With a setting just below LO, the flame will be ON
approximately 53 seconds and OFF 7 seconds of each
minute.

• With a setting at the XLO position, the flame is ON
approximately 7 seconds and OFF 53 seconds of each
minute.

FOR THE BEST RESULTS

• Temperature control will be more accurate if a lid is
used.

• Bring food to a rolling boil; stir well to be sure all the
food is boiling; cover and reduce the heat to just
below LO.

• Check periodically to see if the control knob should
be turned to a lower setting.

• Adjust control knob to lower settings in small steps.

line.
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 tempera­ture, without scorching or burning. This is accom­plished because the XLO setting cycles the flame OFF
and ON for varying lengths of time.

HOW THEY WORK

• The BTU/HR usage on the 9,100 BTU/HR burner
ranges from HI (at 9100) to XLO (at 300). The

BTU/HR usage on the 11,000 BTU/HR burner ranges
from HI (at 11,000) to XLO (at 365).

• There are an infinite number of settings between HI
and XLO; the control knob can be set at any
position.

• If control is set too low to maintain simmer, bring the
food back to a boil before setting a higher simmer
setting.

WHAT TO EXPECT WHEN USING XLO

• The type and quantity of the food will affect which
setting to use.

• The size, type and material of your pan will affect
which setting to use.

• When a large pan is used on a small burner, it may
cause the simmer action to occur mainly in the center
of the pan. When the food is stirred, the cooler food
near the edges of the pan may result in an overall
temperature too cool to simmer. If this happens, turn
the burner up slightly.

• It is normal to stir food occasionally. This is especially
important when simmering for several hours. For
example: homemade spaghetti sauce or beans.

• It is normal not to see simmer bubbles immediately
after the food has been stirred.

• While the flame is ON there may be bubbling; there
should be at least steam and a slight quivering of the
liquid’s surface.

• Simmer bubbles may not be seen when the flame has
cycled OFF. (Models CGX)

holding a match at the ports and turning the control
knob to the HI position. Wait until the flame is burning
all the way around the burner cap before adjusting the
flame to the desired height.

Be sure to turn the ExtraLow burners OFF if a power
failure occurs, as they will not turn back on until both
control knobs are turned OFF first. See “What To Do
If You Smell Gas,” Page 1.

BURNER EFFICIENCY and
FLAME CHARACTERISTICS

The burner flame should be blue in color and stable with
no yellow tips, excessive noise or fluttering. It should
burn completely around the burner cap.

Foreign particles in the gas line may cause an orange
flame during initial use. This should disappear with use.

If the flame does not burn evenly all the way around the
burner cap, be sure the cap is resting correctly on the
burner base and the gas ports are dry.

The burner should light in 4 seconds or less. If a
burner does not light, check to see that the cap is resting
correctly on the burner base.

Page 11

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.

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.

Balanced Pan

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 - Center the pan on the burner grate or

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.

TIGHT FITTING LID - A lid shortens cooking time

by holding the heat inside the 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)

!

▲

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:

• Use a canner with a dark or dull finish to reduce heat
reflecting back to the cooktop surface.

• Select a canner with a flat bottom, rather than one
with a concave, convex or rippled bottom.

• Allow at least 3/8 inch of air space between the
canner overhang and the cooktop surface.

• 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.

• Use care to prevent burns from the large amount of
steam generated by the canning process.

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.

Large or Warped Utensils

Woks and Speciality Pans

Use only a flat bottom wok on electric heating elements.
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.

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).

Custom Accessories

Thermador® offers several accessories for use on dual
or gas burner cooktops.

AWOKRING - a ring designed to hold a round bottom
wok. It is custom fitted to the shape of the grate.

• 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.

GG1 - a cast aluminum griddle with a non-stick finish
that spans two burners. It is custom fitted to the grates.

AEGRIDDLE - an anodized aluminum griddle that
spans two glass ceramic electric elements.

remove water spots or food spatters.

®

to a clean paper towel or cloth.

CLEANERS

TO AVOID ON THE GLASS CERAMIC
SURFACE AND METAL TRIM FRAME: Use of these
types of cleaners may cause discoloration and permanent
damage.

The temperature of the cooking surface during use
reduces the protective qualities of the Cleaning Creme,
so it must be re-applied regularly to maintain the
appearance of the cooktop.

CLEANERS / PRODUCTS

TO USE ON THE CERAMIC

SURFACE

Cooktop Cleaning Creme
Bon Ami

®

(incl. with cooktop)

Soft Scrub®, except on trim frame.
Vinegar (rinse and dry)

CLEAN CARE TECHNIQUES (FOR MOST SOILS)

1. Clean the surface when it is completely cool,
with the exception of spills containing milk, dry
sugar, sugar syrup, or tomato described in the
Special Care Techniques on the following page.
These must be removed IMMEDIATELY.

CAUTION:

DO NOT use any kind of cleaner on

the glass while the cooktop is hot. The resulting
fumes can be hazardous to your health. The heated
cleaner can chemically attack and damage the
cooktop.

• Glass cleaners: Do not use glass cleaners containing
ammonia or chlorine bleach. These ingredients may
etch or stain the cooktop.

• Caustic cleaners: Oven cleaners such as Easy Off
or Dow® may etch the cooktop surface.

• Abrasive cleaners: Metal scouring pads such as

Chore Girl

®

and Kurly Kate® and scrub sponges
such as Scotch Brite® can scratch the cooktop and
leave metal marks.

®

Soap-filled scouring pads such as Rescue

or S.O.S.

can scratch the cooktop surface.

• Powdery cleaners that contain chlorine bleach can
stain the cooktop.

• Cleaners that are flammable may be dangerous

2. Cooktop surface, glass-ceramic: Wipe off greasy
spatters with a clean, damp sponge, cloth or paper
towel. Rinse and dry. Use vinegar if smudge
remains. Apply Cleaning Creme as directed above.
Rub on the cooktop surface. When dry, buff surface
with clean paper towel or cloth.

3. Knobs, plastic: Pull up to remove. Wipe with hot
soapy sponge; rinse and dry. Do not soak.

TYPE OF SOIL

Dry sugar, sugar syrup, milk or tomato spills.
Melted plastic film or foil. All these items
REQUIRE IMMEDIATE REMOVAL. Remove

these types of spills

while the surface is hot using the

only

razor blade scraper. See Page illustration on page16.

Burned-on food soil, dark streaks, and specks

Greasy spatters

Metal marks

POSSIBLE SOLUTION

Failure to remove these soils immediatly can

permanently damage the surface.

• 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.

• Use vinegar or a soapy sponge to remove grease; rinse
thoroughly and dry. Apply Cooktop Cleaning Creme.

• Pans with aluminum, copper or stainless steel bases
may leave marks. Treat immediately, after surface has
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.

Hard water spots

Hot cooking liquids dripped on surface

Surface scratches:

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.

CAUTION: Diamond rings will scratch the surface.

• 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.

Remove boil-overs / stains, before using the cooktop again.

• Can be reduced by removing sand-like grains/grit such
as salt and seasoning from below the pan.

• Can be reduced by using pans with bases that are
smooth, clean, and dry before use. Use recommended
Cooktop Cleaning Creme daily on the cooktop.
