IMPORTANT
• A backguard must be utilized when there is less than a
12" horizontal clearance between combustible
materials and the back edge of the cooktop. The
Thermador Low Back backguard must be ordered
separately and installed at the rear of the cooktop. For
island installations and other installations with more
than 12" clearance, an optional stainless steel Island
Trim is available to cover the backguard mounting
flanges.
• Verify that the appliance is correct for the type of gas
being provided. Refer to “Step 4: Gas Requirements
and Hookup” on page 11 before proceeding with the
installation.

Step 1: Ventilation Requirements
It is strongly recommended that a suitable exhaust hood be
installed above the appliance. Downdraft ventilation should
not be used. The following table indicates the ventilation
hood options and blower capacity guidelines that are
recommended for use with all Thermador cooktops.
Due to the high heat capability of this unit, particular
attention should be paid to the hood and duct work
installation to assure it meets local building codes.
Do not install a microwave oven/ ventilator combination
above the cooktop, as these types of units do not provide
English 3
the proper ventilation and are not suitable for use with the
cooktop.
Select Hood and Blower Models:
• For wall installations the hood width must, at a
minimum, equal the nominal width of the appliance
cooking surface. Where space permits, a hood larger in
width than the cooking surface may be desirable for
improved ventilation performance.
• For island installations the hood width should, at a
minimum, overhang the appliance cooking surface by
3" on each side.
Hood Placement:
• For best smoke elimination, the lower edge of the hood
should be installed 30" above the appliance cooking
surface. (See Figure 1).
• If the hood contains any combustible materials (i.e., a
wood covering), it must be 36"or greater distance
above the cooking surface.
NOTICE:
Most hoods contain combustible components which must
be considered when planning the installation.
Consider Make-Up Air:
• Due to the high volume of ventilation air, a source of
outside replacement air is recommended. This is
particularly important for tightly sealed and insulated
homes.
• A qualified heating and ventilating contractor should be
consulted.
NOTE:
Ventilation hoods and blowers are designed for use with
single-wall ducting. Some local building codes may require
double-wall ducting. Before starting installation, consult
local building codes and agencies to insure that the
installation will meet local requirements.

Important Notes:
• It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador
Professional Cooktops.
• Refer to www.Thermador.com for a complete selection of Professional Ventilation options, Blowers, and
Accessories.
• * For high output gas cooktops (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the cooktop has a grill or griddle, add 200 CFM to the estimated blower capacity. Add 400 CFM if
the cooktop has a 24” griddle or wok. Additional blower capacity may be required for longer duct runs.
• For island applications, it is recommended to use a hood width that exceeds the width of the cooktop by 6”
(overlapping the cooktop by 3” on each end).
• CFM = “cubic feet per minute” (standard blower capacity rating).

Step 2: Cabinet Preparation
1. To ensure professional results, the cabinet and countertop openings should be prepared by a qualified cabinet worker.
2. The clearances shown in Figure 1 are required. The same clearances apply to island installations, except for the overhead cabinets, which must have a space wide enough to accept the island hood.
3. The cooktop is designed to hang from the countertop
by its side flanges. The countertop however, must be
strong enough to support this cooktop. It may be
necessary to add a supporting cleat along each side
(see Figure 2) or a 2 x 4 corner brace (see Figure 3
and Figure 4 and Detail A). Another alternative would
be to construct a deck to set the cooktop on.
4. The cooktop can be installed in various positions with the front either flush or projecting, depending on the countertop’s depth. (See Figure 5, side view of cooktop; see Figure 3, Figure 4, Figure 6 and Figure 7 for alternate mounting positions.)
5. The gas and electrical supply must be located in an
area that is accessible without requiring removal of the
cooktop. The appliance electrical power cord and gas
pipe connection are located on the left rear underside
of the cooktop (except on models with a 24" griddle
where power cord is located in the center), as shown in
Figure 5 and Figure 9.
6. The maximum depth of over head cabinets installed on either side of the hood is 13".
A 36-inch minimum clearance is required between the
cooking surface of the cooktop and the bottom of an
unprotected cabinet. A 30-inch distance can be used when
the bottom of the wood or metal cabinet is protected by not
less than 1/4 inch of a flame retardant material covered
with not less than No. 28 MSG sheet steel, 0.015 inch (0.4
mm) thick stainless steel, 0.024 inch (0.6 mm) aluminum,
or 0.020inch (0.5 mm) thick copper. Flame retardant
materials bear the mark:
UNDERWRITERS LABORATORIES INC. CLASSIFIED
MINERAL AND FIBER BOARDS SURFACE BURNING
CHARACTERISTICS
followed by the flame spread and smoke ratings. These
designations are shown as "FHC (FIame Spread/Smoke
Developed)." Materials with "O" flame spread ratings are
flame retardant. Local codes may allow other flame spread
ratings.
7. When there is less than a 12" horizontal clearance
between combustible material and the back edge of
the cooktop above the cooking surface, a Thermador
Low Backguard must be installed. (See Step 6). When
clearance to combustible material is over 12", a
Thermador Island Trim may be used. Attach the
backguard before sliding the appliance into the final
installed position.
8. Establish the centerline of the cooktop’s desired location. It should be the same as the center of the overhead ventilation hood.
9. Cut the openings for the following installations:
• Wall installation, see Figure 3.
• Island installation, see Figure 4.
10. For models with a 24” griddle, attach the foam strip to countertop centered along the rear about 1/16” from the edge.
11. For installation of a 48" cooktop above two side-by-side
Thermador Warming Drawers, Model No. WD24, refer
to Figure 8. Completing the installation as per Figure 8
will result in the left and right edges of the cooktop
being aligned with the left edge of the left-side warming
drawer and right edge of the right-side warming
drawer. If different alignment is desired, the 1-7/8"
horizontal distance between warming drawer cutouts
may be varied. However, maintain at least a 1-1/8"
distance to avoid interference between the warming
drawers. Attach a 90-degree elbow to the gas cooktop
inlet pipe. All above-the-countertop clearances must be
maintained, as shown in Figure 1.
As defined in the "National Fuel Gas Code" (ANSI
Z223.1/NFPA54-current issue).
NOTES:
• If a solid side cabinet wall exists on one or both sides,
you will need to notch the front corner of the cabinet to
match the countertop notch and to allow clearance for
the cooktop front (see Detail A, Figure 3 and Figure 4).
• If a supporting deck is used, the sides or bottom of the
cutout may be solid combustible or non-combustible
material. If the bottom is solid, provide a 8" by 8" cutout
in the left rear corner of the supporting deck. This will
provide clearance for the gas inlet and power cord,
while also allowing viewing of the product rating label.
• On models which have a 24" griddle with power cord in
the center, provide 2 (two) separate pieces of
supporting deck to allow clearance in center for cord to
pass through.
• Always keep appliance area clean and free from
combustible materials, gasoline and other flammable
vapors and liquids.
• Do not obstruct the flow of combustion and ventilation
air to the unit.

must be disconnected from the gas supply
piping system during any pressure testing of the
system at test pressures in excess of 1/2 psig
(3.5kPa.).
When checking the manifold gas pressure, the
inlet pressure to the regulator should be at least
6.0" W.C. for natural gas or 11.0" for propane.
Do not attempt any adjustment of the pressure
regulator.
Step 5: Electrical Requirements, Connection and Grounding
• All 240 Volt cooktop models require hard wire
connections.
• Observe all governing codes and ordinances when
grounding. In the absence of these codes or
ordinances observe National Electrical Code ANSI/
NFPA No. 70 current issue. See Figure 10 for
recommended grounding method.
• An electrical wiring diagram and schematic have been
attached to the bottom of the cooktop chassis for
access by a qualified service technician. Do not
remove or discard this important information.
Grounding Method for 120 VAC Models
The cooktop is factory equipped with a power supply cord
with a three-prong grounding plug (with polarized parallel
blades).
IT MUST BE PLUGGED INTO A MATING, GROUNDING
TYPE RECEPTACLE THAT IS CONNECTED TO A
CORRECTLY POLARIZED 120 VOLT CIRCUIT (240
VOLT CIRCUIT FOR MODELS WITH 24" ELECTRIC
GRIDDLE. (See Figure 10).
CAUTION
Improper grounding or reverse polarization will
cause malfunction (such as continuous sparking
of the burner igniters). This can damage the
appliance and can create a condition of shock
hazard. If the circuit is not correctly grounded
and polarized, it is the responsibility and
obligation of the installer and user to have the
existing receptacle changed to a properly
grounded and polarized receptacle. This must
be accomplished in accordance with all
applicable local codes and ordinances by a
qualified electrician. In the absence of local
codes and ordinances, the receptacle
replacement shall be in accordance with the
National Electric Code. (See Figure 10.)
• Before installing, turn power OFF at the service panel.
Lock service panel to prevent power from being turned
ON accidentally.
• Always disconnect appliance from the electric supply
either by disconnecting power cord or shutting off the
breaker before servicing the appliance.
• Before you plug in an electrical cord, be sure all
controls are in the OFF position.
• All 120 Volt cooktop models must be plugged into a
mating 3-Prong, Grounding-Type Receptacle. The
receptacle must be connected to a properly grounded
and polarized electrical power supply rated at 120VAC,
Single Phase, 60HZ. See “Electrical Power Supply
Over-current Protection Requirements” on page 13 on
this page for proper over-current protection
requirements for each model.

REMOVED UNDER ANY CIRCUMSTANCES.
Electrical Connection for 240 VAC Models
1. Attach flexible conduit to the junction box.
2. Connect the cooktop lead wires to the junction box supply wires in proper phase:
For all 240 VAC models, connect black (L1) to black,
red (L2) to red, white wire to neutral and green wire
to ground.

Step 6: Backguard Installation
A Low Back backguard must be installed when there is less
than a 12" clearance between combustible materials and
back edge of cooktop. (See Figure 1 and Figure 5.) For
island installations and other installations with over 12"
clearance, an optional stainless
available to cover the backguard mounting flanges. Attach
the backguard before sliding the appliance into the final
installed position. Follow Steps A through C below:
1. Slide backguard over the two flanges on the rear of the appliance. Fasten the front and back with the two screws (see A, Figure 12) provided.
2. Fasten the top of the backguard to the wall with two screws through the backguard. (See B, Figure 12.)
3. Place the backguard cap on top and fasten using the two counter-sink screws provided. (See C, Figure 12.)

Step 7: Burner Test and Adjustment
Install any loose components, such as burner caps and
grates that may have been removed earlier.
Be certain that burner caps seat properly into the burner
bases. Before testing operation of the appliance, verify that
the unit and the gas supply have been carefully checked for
leaks and that the unit has been connected to the electrical
power supply. Turn the manual gas shut-off valve to the
open position.
Test Cooktop Burners
Test Burner Ignition. Select a cooktop burner knob. Push
in and turn counterclockwise to HI. The ignitor/spark
module will produce a clicking sound. Once the air has
been purged from the supply lines, the burner should light
within four (4) seconds.
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow, verify that the
regulator is set for the correct fuel. After adjustment,
retest.
Some orange-colored streaking is normal during the
initial start-up.
Allow unit to operate 4-5 minutes and re-evaluate before
making adjustments.
Test Flame: High Setting. Turn burner on to HI. See
Figure 13 for appropriate flame characteristics. If any of the
cooktop burners continue to burn mostly or completely
yellow, verify that the burner cap is positioned properly on
the burner base, then re-test. If flame characteristics do not
improve, call Thermador.
Test Flame: Low Setting. Turn burner on to LO. Verify
that the flame completely surrounds the burner. There
should be a flame at each burner port and there should be
no air gap between the flame and the burner. If any burners
do not carry over, call Thermador.
The two far left burners feature XLO, causing the flame to
cycle on and off when the knob is set to the XLO range.
This is normal operation.
Repeat the Ignition and Flame Test procedures described
above for each cooktop burner and the grill burner (if so
equipped).
Figure 13: Flame Characteristics
WHEN FLAME IS PROPERLY ADJUSTED:
• There should be a flame at each burner port.
• There should be no air gap between the flame and
burner port.
The gas grill uses a tube-style burner that has an air shutter
which allows adjustment to the amount of primary air inside
the burner tube.
Air shutters of tube-style burners are pre-adjusted at the
factory, and usually do not require readjustment except
under rare conditions such as installation at high altitude.
If grill burner/flame adjustment is required, go to the
procedure: “Flame Adjustment (if necessary)”.
English 14
Flame Adjustment (if necessary)
Tube-style gas burners used in Thermador appliances
have air shutter systems which are similar to the illustration
in Figure 14, and can be adjusted using the following
method (unless adjustment is not recommended). It is
necessary to remove the burner from the appliance in order
to perform air-shutter adjustments.
• Loosen shutter screw(s) and turn shutter to new
position.
• Adjust the shutter to more-closed position if the flame
is lifting or blowing, or is not carrying over.
• Adjust the shutter to more-open position if the flame is
too yellow. (See Figure 14.)
• Retighten the shutter screw(s).
• After adjustment, reinstall the burner and perform
flame evaluation. The air shutter must fit over the
orifice hood for proper operation of the burner.
• Repeat procedure as needed until flame characteristics
are acceptable. (See Figure 13.)
