This appliance has been tested in accordance
with ANSI Z21.1 2000, Standard for House-
hold Cooking Appliances (USA) and in accor-
dance with CAN 1.1-M81 Domestic Gas Ranges
(Canadian).
It is strongly recommended that this appliance
be installed in conjunction with a suitable over-
head vent hood (see “Ventilation Require-
ments” on page 10). Due to the high heat
capability of this unit, particular attention
should be paid to the hood and ductwork
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 appli-
ance should be installed in accordance with the
To eliminate risk of burns or fire caused
by reaching over heated surface units, cabi-
net storage located above the surface units
should be avoided
CAUTION
When connecting the unit to propane gas,
make certain the propane gas tank is
equipped with its own high pressure regu-
lator in addition to the pressure regulator
supplied with this unit. The maximum gas
pressure to this appliance is not to exceed
14.0 inches (37 mb) water column from the
propane gas tank regulator.
This unit is designed as a cooking appliance.
Based on safety considerations never use it
for warming or heating a room.
CAUTION
National Fuel Gas Code ANSI Z223.1 Current
Issue and National lectrical Code ANSI/
NFPA 70-Current Issue. In Canada, installa-
tion must be in accordance with the CAN 1 -
B149.1 and .2 - Installation Codes for Gas Burn-
ing Appliances and/or local codes.
This appliance is equipped with an intermit-
tent/interrupted ignition device that cycles
the two far left surface burners on and off when

Page 10
VENTILATION REQUIREMENTS
It is strongly recommended that a suitable
exhaust hood be installed above the range.
Downdraft ventilation should not be used.
The table below indicates the Thermador hoods,
by model number, that are recommended for
use with all ranges.
1 Select Hood and Blower Models
For wall installations, the hood width must, at
a minimum, equal the width of the range cook-
ing surface. Where space permits, a hood larger
in width than the cooking surface may be
desirable for improved ventilation perfor-
mance.
For island installations, the hood width should,
at a minimum, overhang the range cooking
surface by 6″ on both sides.
CAUTION: Ventilation hoods and blowers
are designed for use with single wall ducting.
However, some local building codes or inspec-
tors 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.
Hood blower speeds should be variable to
reduce noise and loss of heated or air condi-
tioned household air when maximum ventila-
tion is not required. Normally, the maximum
blower speed is only required when using the
grill.
2 Hood Placement
For best smoke elimination, the lower edge of
the hood should be installed a minimum of 30″
to a maximum of 36″ above the range cooking
surface.
If the hood contains any combustible materials
(i.e. a wood covering), it must be a minimum of
36″ above the cooking surface.
3 Consider Make-Up Air
Due to the high volume of ventilation air, a
source of outside replacement air is recom-
mended. This is particularly important for
tightly sealed and insulated homes.
A qualified heating and ventilating contractor
should be consulted.

Page 11
CABINET PREPARATION
1. The range is a freestanding unit. If the unit
is to be placed adjacent to cabinets, the
clearances, shown in Figures 1A and 1B,
are required. The same clearances apply to
island installations, except for the over-
head cabinets, which must have a space
wide enough to accept the flared island
hood.
2. The 30″ and 36″ ranges may be recessed
into the cabinets beyond the edge of the
front face of the oven (see Figures 1A & 1B).
In these installations, the door and cabinet
can cause a pinching hazard.
CAUTION
3. The gas and electrical supply should be
within the zones shown in Figures 2A or 2B
on page 12.
4. The maximum depth of overhead cabinets
installed on either side of the hood is 13″.
5. Any openings in the wall behind the range
and in the floor under the range must be
sealed.
6. When there is less than a 12″ horizontal
clearance between combustible material
and the back edge of the range above the
cooking surface, a Thermador Low Back or
High Shelf backguard must be installed
(see Figure 1A). When clearance to com-
bustible material is over 12″, a Thermador
Island Trim may be used (see Figure 1B).
Figures 1A and 1B indicate the space re-
quired for each type of backguard.
7. Always keep appliance area clear and free
from combustible materials, gasoline and
other flammable vapors and liquids.
8. Do not obstruct the flow of combustion and
ventilation air to the unit.

ELECTRICAL SUPPLY—
DUAL FUEL RANGES
Installation of Dual Fuel ranges must be
planned so that the rough-in of the junction
box for the receptacle or conduit connection
will allow maximum clearance to the rear of
the unit.
When the power supply cord (not supplied) or
conduit is connected to the mating receptacle
or junction box cover, the combined plug/
receptacle or junction box cover/conduit con-
nector should protrude no more than 2-1/4
inches from the rear wall (see Figure 2C ).
This is especially critical if the junction box in
the wall will be directly behind the junction
box on the unit when the unit is installed (see
Figure 7 on Page 20 for location of junction box
on unit). To minimize binding when the unit is
connected to the receptacle or junction box,
orient the receptacle or conduit connector, and
slide back into position.

UNPACKING, MOVING, & PLACING THE RANGE
Proper equipment and adequate manpower
must be used in moving the range to avoid
damage to the unit or the floor. The unit is
heavy and rests on adjustable steel legs.
CAUTION
The range has an approximate shipping weight
as shown in Chart A. It is recommended that
the grates, griddle, burner caps, front kick
panel and oven racks be removed to facilitate
handling. This will reduce the weight as shown
in Chart A and allow the range to pass through
30″ doorways (see Chart B and Figures 1A and
1B on Page 11). Do not remove the grill or
griddle assemblies.
Remove the outer carton and packing material
from the shipping base. Remove the front kick
panel (see Figure 3) by removing two (2) screws
at the top and pulling forward. The dual fuel
ranges are held to the skid by four (4) bolts. The
front two (2) are behind the kick panel, (see
Figure 3), and the rear two (2) are located on
the bottom flange of the range back (see Figure
4). All-gas ranges are held in place by 4 bolts,
two (2) as shown in Figure 3, and two (2) at the
rear as shown in Figure 4. After removing the
bolts, the range must be lifted and removed
from the skid.
