SECTION ONE: GENERAL SAFETY INSTRUCTIONS
PRECAUTIONS
SAFETY PRACTICES TO AVOID
PERSONAL INJURY
When properly cared for, your
new Thermador PROFESSIONAL
Range has been designed to be a
safe, reliable appliance. However,
use extreme care when using this
restaurant caliber range as this
type of appliance provides intense
heat and can increase the accident
potential. When using kitchen
appliances, basic safety
precautions must be followed,
including the following:
Read this Care and Use Manual
carefully before using your new
range to reduce the risk of fire,
electrical shock, or injury to
persons.
Insure proper installation and
servicing. Follow the installation
instructions provided with this
product. Have the range installed
and grounded by a qualified
technician.
Have the installer show you where
the gas supply shut-off valve is
located so that you know how
and where to turn off the gas to
the range.
If you smell gas, your installer has
not done a proper job of checking
for leaks. If the connections are
not perfectly tight, you can have a
small leak and therefore a faint
gas smell. Finding a gas leak is
not a “do-it-yourself” procedure.
Some leaks can only be found
with the burner control in the ON
position and this must be done by
a qualified service technician. See
Inside Front Cover regarding gas
leaks.
In the event a burner goes out
and gas escapes, 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 range.
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 technician.
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 the appliance.
CAUTION: Do not store items
of interest to children above the
range or at the back of it. If
children should climb onto the
appliance to reach these items,
they could be seriously injured.
Never use any part of the cooktop
or oven for storage. Flammable
materials can catch fire and plastic
items may melt or ignite.
Do not hang articles from any part
of the appliance or place anything
against the oven. Some fabrics
are quite flammable and may catch
on fire.
If the range is near a window, be
certain the curtains do not blow
over or near the cooktop burners;
they could catch on fire.
DO NOT USE WATER ON
GREASE FIRES. Turn appliance
off and smother fire with baking
soda or use a dry chemical or
foam-type extinguisher.
Never let clothing, potholders, or
other flammable materials come
in contact with or too close to any
element, burner or burner grate
until it has cooled. Fabric may
ignite and result in personal injury.
Use only dry potholders: moist or
damp potholders on hot surfaces
may cause burns from steam. Do
not use a towel or other bulky
cloth in place of potholders. Do
not let potholders touch hot
elements, hot burners, or burner
grates.
For personal safety, wear proper
apparel. Loose fitting garments
or hanging sleeves should never
be worn while using this
appliance. Some synthetic fabrics
are highly flammable and should
not be worn while cooking.
Do not use aluminum foil to line
any part of the oven or cooktop.
Use of a foil liner could result in a
shock or fire hazard, or the
obstruction of 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
finish of the oven or the cooktop.
WARNING
!
TO REDUCE THE RISK
OF TIPPING OF THE
APPLIANCE, IT MUST
BE SECURED BY A
PROPERLY
INSTALLED ANTI-TIP
DEVICE. VERIFY THAT THE
ANTI-TIP DEVICE IS ENGAGED PER INSTALLATION
IN–STRUCTIONS. (NOTE:
ANTI-TIP DEVICE IS
REQUIRED ON ALL 30" AND
36" RANGES)
Page 4
SECTION ONE: GENERAL SAFETY INSTRUCTIONS
PRECAUTIONS
WARNING: The appliance
is for cooking. Based on safety
considerations, never use the
oven or cooktop to warm or heat
a room. Also, such use can
damage the cooktop or oven
parts.
When using the cooktop: DO
NOT TOUCH THE BURNER
GRATES OR THE IMMEDIATE
SURROUNDING AREA. Areas
adjacent to the burners may
become hot enough to cause
burns.
Never leave the cooktop
unattended when using high
flame settings. Boil overs cause
smoking and greasy spillovers that
may ignite. More importantly, if
the burner flames are smothered,
unburned gas will escape into the
room. See Inside Front Cover
regarding gas leaks.
Only certain types of glass, heatproof glass-ceramic, ceramic,
earthenware, or other glazed
utensils are suitable for cooktop
use. This type of utensil may break
with sudden temperature
changes. Use only on low or
medium heat settings according
to the utensil manufacturer’s
directions.
Do not heat unopened food
containers; a buildup of pressure
may cause the container to burst.
During cooking, set the burner
control so that the flame heats
only the bottom of the pan and
does not extend beyond the
bottom of the pan.
Avoid using high flame setting
with a pan larger than the grate or
with one that spans more than
one burner, such as a griddle, for
prolonged periods of time. This
can result in poor combustion that
generates harmful by-products.
Use caution to insure that drafts like
those from forced air vents or fans do
not blow flammable material toward
the flames or push the flames so that
they extend beyond the edges of the
pot.
Always use utensils that have flat
bottoms, large enough to cover
the burner. The use of undersized
utensils could expose a portion of
the flame and may result in ignition
of clothing.
To minimize burns, ignition of
flammable materials and
unintentional spillovers, position
handles of utensils inward so they
do not extend over adjacent work
areas, cooking areas, or the edge
of the cooktop.
Hold the handle of the pan to
prevent movement of the utensil
when stirring or turning food.
DO NOT use pots or pans on the
grill section.
Do not use the grill for cooking
excessively fatty meats or
products which promote flareups.
The optional cutting board
accessory must be removed
before operating the griddle
beneath or burners adjacent to it.
GREASE IS FLAMMABLE. Let hot
grease cool before attempting to
handle it. Avoid letting grease
deposits collect. Clean after each
use.
For proper lighting and
performance of the burners, keep
the igniter ports 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 38.
WARNING
After a spill or boil over, turn
off the burner and clean around
the burner and burner port.
After cleaning, check for proper
operation.
Clean the cooktop with caution.
Avoid steam burns; do not use a
wet sponge or cloth to clean the
cooktop while it is hot. Some
cleaners produce noxious fumes
if applied to a hot surface. Follow
directions provided by the cleaner
manufacturer.
Be sure all cooktop controls are
turned off and the cooktop is cool
before using any type of aerosol
cleaner on or around the cooktop.
The chemical that produces the
spraying action could, in the
presence of heat, ignite or cause
metal parts to corrode.
When using the oven: DO NOT
TOUCH THE INFRARED
BURNERS, THE INTERIOR
SURFACES OF THE OVEN OR
THE EXTERIOR AREA
IMMEDIATELY SURROUNDING THE DOOR. Interior oven
surfaces become hot enough to
cause burns. The heat deflector,
which deflects heat away from the
cooktop and the trim on the top
and sides of the oven door, will
also be hot when the oven is in
use.
Place oven racks in desired
position while oven is cool. If a
rack must be moved while the
oven is hot, do not let the
potholders contact the infrared
burner.
Use care when opening the oven
door; let hot air or steam escape
before removing or replacing
foods.
Before self-cleaning the oven,
remove the broiler pan, oven racks
and any other utensils, and excess
spillage.
Page 5
SECTION ONE: GENERAL SAFETY INSTRUCTIONS
PRECAUTIONS
Do not clean, rub, damage, move
or remove the door gasket. It is
essential for a good seal during
baking and while self-cleaning the
oven.
Protect the self-cleaning feature.
Clean only those parts indicated
in this booklet. Do not use
commercial oven cleaners or oven
liner protective coatings of any
kind in or around the large selfcleaning oven.
DO NOT obstruct the flow of
combustion or ventilation air.
For safety reasons and to avoid
equipment damage, never sit,
stand, or lean on the oven door.
Service should only be done by
authorized Technicans. Techni-
BEFORE USING YOUR RANGE FOR THE FIRST TIME, CHECK THAT YOU HAVE THESE ITEMS:
cians must disconnect the power
supply before servicing this unit.
Listen to be sure the cooling
blower runs whenever the oven
controls are set to broil or selfclean. If the fan does not operate,
do not use the oven. Call an
authorized service center for
service.
Clean the ventilator hood and
filters above the range frequently
so grease from cooking vapors
does not accumulate on them.
• In case of fire or when intentionally “flaming” liquor or other spirits on the cooktop, follow hood
manufacturer’s instructions.
California Proposition 65
Warning: The burning of gas
cooking fuel and the elimination
of soil during self-cleaning
generate some by-products which
are on the list of substances which
are known by the State of
California to cause cancer or
reproductive harm. California law
requires businesses to warn
customers of potential exposure
to such substances. To minimize
exposure to these substances,
always operate this unit according
to the instructions contained in
this booklet and provide good
ventilation to the room when
cooking with gas, during and
immediately after self-cleaning the
oven.

Board, Griddle Cover, Wok Support Ring and
other accessories are available from your
Thermador Dealer. Contact the Thermador Parts
Department toll-free at 800/735-4327 for more
information.
4. Position the racks correctly in the oven.
The correct rack position depends on the recipe
and the cooking mode. The rack positions are
numbered from the bottom of the oven, like an
elevator. Rack position 3 is the most frequently
used position. Place rack(s) in the proper position before turning on the oven.
Insert the racks as follows:
a. Hold the rack with the back rail in the up
position towards the rear of the oven. Slip it
into the oven so the rack slides are between
the rack and the rack guides.
b. Tip the front of the rack up slightly as it slides
into the oven so that the safety stops clear
the rack slides. The safety stops on the back
of the rack will keep it from sliding out of the
oven when it is pulled forward.

• Press in on the knob and turn
it counter-clockwise to the HI
setting.
• The igniter for the selected
sealed burner clicks and
sparks.
• After flame ignition, the
igniters stop clicking.
• Rotate the knob to any flame
setting between HI and LO.
• The Blue Burner Signal Light,
between the burners, will light
when adjacent burners are lit.
They will remain on until the
burner is turned off.

The drawing shows that the
control knob has an additional
range between the LO and XLO
settings. When the knob is set
within this range, the flame pulses
off and on. By varying the length
of time the flame is off and on,
the heat is reduced even further
to cook delicate foods. For
example, these very low settings
are suitable for simmering and
poaching, melting chocolate and
butter, holding cooked foods at
temperatures without scorching
or burning, etc.
SECTION FOUR: USING THE COOKTOP
Operation of the ExtraLow
Burners
• XLO, the very lowest setting,
is achieved by cycling the flame
ON for approximately 8
seconds and OFF for 52
seconds of each minute.
• When the knob is set just
below the LO setting, the flame
will cycle ON for approximately
52 seconds and OFF for 8
seconds of each minute.
• To vary the amount of low heat
to suit the food and quantity,
the control can be set
anywhere within the LO and
XLO range marked on the
knob.
ExtraLow Settings
• The number and dash
designations, shown in the
drawing, are for reference only.
Numbers do not actually
appear on the knob. The
number indicates the position
of the flame setting as
represented on the cooking
chart, pages 17 and 18, with #4
being hotter than #1.
• To maintain a low or simmer
heat, bring food to a rolling
boil. Stir well, then cover the
pan and lower the heat to a
setting just below LO.
• Check periodically to see if the
control knob should be turned
to another setting.
• If an over-size pan is used, the
simmer action may occur
mainly in the center of the pan.
To equalize the temperature
throughout the food, stir the
food around the outer edges
of the pan into the food in the
center.
• It is normal to stir food
occasionally while simmering.
This is especially important
when simmering for several
hours, such as for a homemade
spaghetti sauce or beans.
• When lowering the flame
setting, adjust it in small steps.
• If the setting is too low to hold
a simmer, bring the food back
to a boil before re-setting to a
higher heat.
• It is normal not to see simmer
bubbles immediately after the
food has been stirred.
• There may be bubbling when
the flame cycles ON and no
bubbles when the flame is OFF.
Even when the flame is OFF,
there will be steam and a slight
quiver on the liquid’s surface.

Components
Each burner has its own electronic
igniter that sparks when the
burner is turned on. Each burner
should light in 4 seconds or less.
If a burner does not light, check
to see that the cap is positioned
correctly on the base. Do not
touch the burners when the
igniters are sparking. If a burner
fails to ignite, refer to the section
on Page 42, “Before Calling for
Service.”
IGNITER
ExtraLow Techniques
• The type and quantity of food
affects which setting to use.
• The pan selected affects the
setting. Its size, type, material,
and whether a lid is used, all
affect the consistency of the
cooking temperature.
