MPORTANT:
All ranges must be installed with a
backguard. Models PRG304 and
PRDS304 are shipped from the
factory with a standard 9" back-
guard. For all other models one of
three available backguards must be
ordered separately and installed at
the back of the range. The three
backguard choices include a Low
Back Guard, High Shelf, or Island
Trim. See STEPS 2 and 6.
CAUTION:
(1) 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
this unit. The maximum gas
pressure to this appliance is not
to exceed 14.0 inches (37mb)
water column from the propane
gas tank regulator.
Check local building codes for the proper
method of appliance installation. Local
codes vary. Installation, electrical con-
nections and grounding must comply
with all applicable codes. In the absence
of local codes the appliance should be
installedinaccordancewiththeNational
Fuel Gas Code ANSI Z223.1 Current
IssueandNationalElectricalCodeANSI/
NFPA 70-Current Issue. In Canada, in-
stallation must be in accordance with
the CAN 1-B149.1 and .2 – Installation
Codes for Gas Burning Appliances and/
or local codes.
This appliance has been tested in ac-
cordance with ANSI Z21.1 Current Is-
sue, Standard for Household Cooking
Appliances (USA) and in accordance
with CAN 1.1-M81 Domestic Gas
Ranges (CANADIAN).
(2) This unit is designed as a
cooking appliance. Based on
safety considerations never use it
for warming or heating a room.
It is strongly recommended that this
appliance be installed in conjunction
with a suitable overhead vent hood.

1. Select Hood and Blower Models:
• Hood blower speeds should be vari-
able to reduce noise and loss of heated
or air conditioned household air when
maximum ventilation is not required.
Normally, the maximum blower speed
is only required when using the grill.
• For wall installations, the hood width
must, at a minimum, equal the width of

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 insu-
lated homes.

Notes:
* For wall installations where adequate space is available, the installer or user may elect to use a hood that is wider than the range
cooking surface. This may be particularly beneficial for those cases, such as a long duct run or heavy usage of the grill, in which
improved capturing of the cooking exhaust is desired.
** Thermador offers a choice of remote (VTR1000Q or VTR1400q) or in-hood (VTN1000Q) blowers for use in wall installations.

• Due to the weight, a dolly with soft
wheels should be used to move this
unit. The weight must be supported
uniformly across the bottom (See
Fig. 7).
• After transporting the professional
range by dolly close to its final
location, the range can be tipped
back and supported on the rear
legs while the dolly is carefully
removed. THE FLOOR UNDER
THE LEGS SHOULD BE PRO-
TECTED (WOOD STRIPS, CAR-

tions should be made (STEPS 5 and
6), and the backguard installed
(STEP 7) before the range is placed
in its final position.
• For proper performance the profes-
sional range must be level. The
range is leveled by adjusting the
legs with a wrench. Replace the
kick panel and oven doors by
reversing the procedure described
above. It is important that the
two (2) screws retaining the
kick panel are secure to pre-
vent accidental access to live

STEP H: Using the 1/4"-20 x 1/2" Hex Head
Bolt, Hex Nut and two (2) Flat Washers,
securely attach the Adjustable Anti-Tip
Channel to the existing hole in the flange
located at the bottom rear of the range.
(There are two (2) holes in the range flange,
so be certain to select the hole that is on the
same side as the mounting bracket.) The

STEP8:TESTANDADJUSTMENT
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 alignment slots in 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 electric
power supply. Turn the manual gas shut-off valve to the open position.
Check operation of the sealed gas burners and grill by pushing and
turning each knob counterclockwise to “HI”. The burner igniters will click
until the flame ignites. The two far left sealed burners feature XLO®,
causing the flame to cycle on and off when the knob is set to the XLO
range. This is normal operation.
CAUTION
Thermador recommends that
burner adjustments be made by
a qualified technician at the
time of installation. Extreme
care should be used when
adjustments are made after
installation. Improper or lack of
adjustments may void your
warranty.
Burner flames should be blue and stable with no yellow tips, excessive
noise, or lifting of the flame from the burner. If any of these conditions
exist, check that the air shutter (grill, griddle and gas oven only) or burner
ports are not blocked or clogged. Remove any blockages that exist.
If the flame is too yellow, indicating insufficient air, adjust the shutter

TO CLEAN AND PROTECT
EXTERIOR SURFACES
The stainless steel surfaces may be cleaned by wiping
with a damp soapy cloth, rinsing with clear water and
drying with a soft cloth to avoid water marks. Any mild
glass cleaner will remove fingerprints and smears.
DO NOT allow deposits to remain for long periods of
time.
DO NOT use ordinary steel wool or steel brushes.
Small bits of steel may adhere to the surface causing
rust.
For discolorations or deposits that persist, refer to the
Care and Use Manual.
DO NOT allow salt solutions, disinfectants, bleaches or
cleaning compounds to remain in contact with stain-
less steel for extended periods. Many of these com-
pounds contain chemicals which could prove harmful.
Rinse with water after exposure and wipe dry with a
clean cloth.
To polish and protect the stainless steel, use a cleaner/
polish such as Stainless Steel Magic®.
