PRG Professional Ranges Care and Use
Safety Practices to Avoid Personal Injury
Section One: General Safety Instructions
PRECAUTIONS
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,
electric 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
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
not a “do-it-
time to dissipate. Wait at least 5
minutes before using the range.
®
Do not repair or replace any
part of the appliance unless spe-
cifically 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 foamtype 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 burners, or
burner grates.
For personal safety, wear
proper apparel. Loose fitting gar-
ments 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 IN-
STALLED ANTI-TIP DEVICE. VERIFY THAT THE
ANTI-TIP DEVICE IS ENGAGED
PER INSTALLATION INSTRUCTIONS. (NOTE: ANTI-TIP DEVICE
IS REQUIRED ON ALL 30” AND
36” RANGES.)
Page 4
PRG Professional Ranges Care and Use Section One: General Safety Instructions
Safety Practices to Avoid Personal Injury
PRECAUTIONS
Warning: The appliance is for
cooking. Based on safety consider-
ations, 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,
heat-proof 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.
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 un-
dersized 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 prod-
ucts which promote flare-ups.
The optional cutting board accessory must be removed before operating the grill burner
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 12.
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 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 hot infrared burner.
Use care when opening the
oven door; let hot air or steam
escape before removing or replacing foods.
Do not rub, damage, move or
remove the door gasket. It is
essential for a good seal during
baking.
Be careful not to damage the
screen covering the infra-red
broiler of the gas oven. If the
screen is damaged, air can enter the
distribution box behind the screen,
possibly resulting in an explosion.
In the event that personal
clothing catches fire, DROP
AND ROLL IMMEDIATELY
to extinguish flames.

PRG Professional Ranges Care and Use
Section One: General Safety Instructions
PRECAUTIONS
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. Technicians must disconnect the power
supply before servicing this unit.
SAVE THESE INSTRUCTIONS
BEFORE USING YOUR RANGE FOR THE FIRST TIME,
CHECK THAT YOU HAVE THESE ITEMS:
Clean the ventilator hood and filters above the range frequently so
grease from cooking vapors does
not accumulate on them.
Turn the ventilator OFF in case of
fire or when intentionally “flaming”
liquor or other spirits on the
cooktop. The blower, if in operation, could unsafely spread the
flames.
California Proposition 65
WARNING:
The burning of gas cooking fuel 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.

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.
Remove or reposition the racks as follows:
a. Pull the rack forward,
b. Lift the front of the rack up so the safety stops clear the rack slides.
c. Pull the rack forward to remove.
Caution
Aluminum foil should never be used to cover the oven racks
or to line the oven. It may cause damage to the oven if it
touches the infrared broiler or when heat is trapped beneath it.
Before baking or broiling for the first time, the oven and broiler should be
turned on separately to burn off the manufacturing oils. Turn the oven on
to 450˚F. for 20 to 30 minutes; then turn the broiler to "Broil" for same
length of time. You may wish to turn on the ventilator above your range
during this time.
