Important Installation Information
GAS type verification
Verify the type of gas supplied to the location. Ensure that the appliance is con-
nected to the type of gas for which it is certified. All models are certified for use with
natural gas. Field conversion of the appliance for use with propane gas supply will
require a conversion kit.
WARNING
To avoid possible burn or fire hazard, a backguard designed specifically
for this range must be installed whenever the range is used.
Refer to “Chart C: Backguard Kit Model Numbers” on page 23, for the correct
backguard models that are designed for this range. After selecting the correct
backguard, the range must be installed properly, using the minimum clear-
ances to combustible surfaces specified in the Cabinet Preparation instruc-
tions on Page 5.
Important: • A backguard must be utilized when there is less than a 12” horizontal clearance
between combustible materials and the back edge of the range. A Thermador
backguard must be ordered separately and installed at the rear of the range (A
Low Back is supplied with 30" model). For island installations and other installa-
tions 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 5: Gas Requirements and Hookup” on page 15 before proceeding with the
installation.
This appliance has been tested in accordance with ANSI Z21.1, Standard for
Household Cooking Appliances (USA) and in accordance with CAN 1.1-M81
Domestic Gas Ranges (Canadian).
It is strongly recommended that this appliance be installed in conjunction with a suit-
able overhead vent hood. (See “Step 1: Ventilation Requirements” on page 3.) 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.
Check local building codes for the proper method of appliance installation. Local
codes vary. Installation, electrical connections and grounding must comply with all
applicable codes. In the absence of local codes the appliance should be installed in
accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54 current issue
and National Electrical Code ANSI/NFPA 70-current issue. In Canada, installation
must be in accordance with the CAN 1-B149.1 and .2 – Installation Codes for Gas
Burning Appliances and/or local codes.
Gas Supply:
Natural Gas – 6 inch water column. (14.9 mb) min., 14 inch (34.9 mb) maximum
Propane Gas – 11 inch water column. (27.4 mb) min., 14 inch (34.9 mb) maximum
Electric Power Supply:
(See Page 17 for specifications.)

CAUTION
When connecting the unit to propane gas, make certain the propane gas
tank is equipped with its own high-pressure regulator in addition to the
pressure regulator supplied with the range. The maximum gas
pressure to this appliance must not exceed 14.0 inches water
column (34.9 mb) from the propane gas tank to the pressure
regulator.
CAUTION
This unit is designed as a cooking appliance. Based on safety
considerations, never use it for warming or heating a room.
This appliance complies with one or more of the following standards:
• UL 858, Standard for the Safety of Household Electric Ranges
• UL 923, Standard for the Safety of Microwave Cooking Appliances
• UL 507, Standard for the Safety of Electric Fans
• ANSI Z21.1, American National Standard for Household Cooking Gas Appli-
ances
• CAN/CSA-C22.2 No. 113-M1984 Fans and Ventilators
• CAN/CSA-C22.2 No. 61-M89 Household Cooking Ranges
It is the responsibility of the owner and the installer to determine if additional require-
ments and/or standards apply to specific installations.
Due to the high heat of the cooktop burners, installing a microwave oven with a ven-
tilation system over the cooktop is not recommended.
CAUTION
To eliminate risk of burns or fire caused by reaching over heated surface
units, cabinet storage located above the surface units should be avoided.
Step 1: Ventilation Requirements
It is strongly recommended that a suitable exhaust hood be installed above the
range. Downdraft ventilation should not be used. The Table on page 5 indicates the
ventilation hood options and blower capacity guidelines that are recommended for
use with all Thermador ranges.
1. Select Hood and Blower Models:
• For wall installations, the hood width must, at a minimum, equal the width of the
range 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 overhang the range cooking sur-
face by a minimum of 3" on each side.
Important: Ventilation hoods and blowers are designed for use with single wall ducting.
However, some local building codes or inspectors may require double wall ducting.
Consult local building codes and/or local agencies, before starting, to assure that
hood and duct installation will meet local requirements.
Do not install a microwave oven/ventilator combination above the range, as these
type of units do not provide the proper ventilation and are not suitable for use with
the range.

Page 4
2. Hood Placement:
• For best smoke elimination, the lower edge of the hood should be installed 36"
above the range cooking surface. (See Figure 1).
• If the hood contains any combustible materials (i.e. a wood covering), it must be
a minimum of 40" above the cooking surface.
3. 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.

Important Notes:
• It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador Pro-
fessional Ranges.
• Refer to www.thermador.com for a complete selection of Professional Ventilation options, Blowers, and Accesso-
ries.
• * For high output gas ranges (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the range has a grill or 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 range by 6” (overlap-
ping the range by a minimum of 3” on each end).
• CFM = “cubic feet per minute” (standard blower capacity rating).

Page 5
Step 2: Cabinet Preparation
1. The range is a free standing unit. If the unit is to be placed adjacent to cabinets,
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 flared island hood, as indicated in Figure 1.
2. These ranges may be recessed into the cabinets beyond the edge of the front
face of the oven (See Figure 2a and Figure 2b).
CAUTION
In these installations, the door and cabinet can cause a pinching hazard.
3. The gas and electrical supply should be within the zones shown in Figure 3a.
Note: The maximum depth of over head cabinets installed on either side of the hood is
13".
A 40-inch minimum clearance is required between the top of the cooking surface
and the bottom of an unprotected cabinet. A 36-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 0.020 inch (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.
4. Any openings in the wall behind the range and in the floor under the range must
be sealed.
5. When there is less than a 12" horizontal clearance between combustible mate-
rial and the back edge of the range above the cooking surface, a Thermador
Low Back or Pot and Pan Shelf must be installed. (See Figure 2a). When clear-
ance to combustible material is over 12", a Thermador Island Trim may be
used. (See Figure 2b). Figures 2a and 2b indicate the space required for each
type of backguard.
6. Always keep appliance area clear and free from combustible materials, gasoline
and other flammable vapors and liquids.
7. Do not obstruct the flow of combustion and ventilation air to the unit.
8. A (4) inch minimum clearance is needed when the range is installed beside a
combustible side wall.
A s defined in the “National Fuel Gas Code” (ANSI Z223.1, Current Edition).
