Step 1: Ventilation Requirements
It is strongly recommended that a suita ble exhaust hood be
installed above the appliance. Downdraf t ventilation sh ould
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.
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 installed a minimum of 40”
above the cooking surface.
NOTICE:
Most hoods contain combustible components which must
be considered when planning the installation.
Do not install a microwave oven/ ventilator combination
above the cooktop, as these types of units do not provide
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.

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.
48” 6 burners with griddle
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 griddle, add 200 CFM to the estimated blower capacity. 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).
• **Not all 48” Pro Wall Hood models can accommodate a 1300 CFM blower option.
• 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, depe n din g 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, 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 o ther flame sp re ad
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 Th e rm ad o r
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 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 warmin g 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.
• 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.

back edge of cooktop. (See Figure 1 and Figure 5.) For
island installations and other installations with over 12"
clearance, use the stainless steel trim channel that comes
already mounted at the back of the cooktop. 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 11) provided.
2. Fasten the top of the backguard to the wall with two screws through the backguard. (See B, Figure 11.)
3. Place the backguard cap on top and fasten using the two counter-sink screws provided. (See C, Figure 11.)

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 carefu lly 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
T est Burner Ignition. Select a cooktop burn er knob. Pu sh
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.

Test Flame: High Setting. Turn burner on to HI. See
Figure 12 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. Tur n 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.
