This appliance has been tested in
accordance with ANSI Z21.1b-1993
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 suitable overhead vent hood.
(See Step 1 for Ventilation Require-
ments.) 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. To eliminate risk of
burns or fire caused by reaching
over heated surface units, cabinet
storage located above the surface
units should be avoided.
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
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 the
30", 36", and 48" 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, at a minimum, overhang the
range cooking surface by 6" on both
sides.

30" RANGE
36" RANGE
48" RANGE
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.

IMPORTANT INSTALLATION INFORMATION

absence of local codes the appliance
should be installed in accordance with
the National Fuel Gas Code ANSI
Z223.1 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.
Verify the type of gas being used at the
installation site. As shipped from the
factory, all units are configured for use
on natural gas. For use with propane
gas, the unit must be converted. Field
conversion for use with propane must
only be done by qualified service
personnel. Contact the dealer when
the unit was purchased or Thermador
(800/735-4328). The field conversion
kit for all Professional Series ranges is
Thermador Model PROLPKIT, PN 35-00-549.
For installations at 6,000 feet above sea
level or higher, it is necessary to de-rate
the appliance. Contact your local gas

STEP 1: VENTILATION REQUIREMENTS

CAUTION: 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.
• Hood blower speeds should be
variable 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.
2. Hood Placement:
• For best smoke elimination, the lower

setting.
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 water column from the
propane gas tank regulator.
(2) This unit is designed as a
cooking appliance. Based on safety
considerations never use it for
warming or heating a room.
edge of the hood should be installed a
minimum of 30" to a maximum of 36"
above the range cooking surface. (See
Fig. 1).
• If the hood contains any combustible
materials (i.e. a wood covering), it must
be a minimum of 42" 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.
