This appliance has been tested in accordance with
ANSI Z21.1 Current Issue Standard for Household
Cooking Appliances (USA).
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 build-
ing codes.

Important Installation Information
CAUTION
To eliminate risk of burns or fire caused by
reaching over heated surface units, cabinet
storagelocatedabovethesurfaceunitsshould
be avoided.
Check local building codes for the proper method of
appliance installation. Local codes vary. Installation, elec-
trical 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/NFPA54-current
IssueandNationalElectricalCodeANSI/NFPA70-current
Iissue.
This appliance is equipped with an intermittent/
interruptedignitiondevicethatcyclesthetwofarleft
surface burners on and off when in the ExtraLow®
setting.

Step 1: Ventilation Requirements
Itisstronglyrecommendedthat
a suitable exhaust hood be in-
stalled above the range.
Downdraftventilationshouldnot
be used. The table below indi-
cates the Thermador hoods, by
model number, that are recom-
mended 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 cooking
surface. Where space permits, a
hood larger in width than the
cooking surface may be desir-
ableforimprovedventilationper-
formance.
•Forislandinstallations,thehood
widthshould,ataminimum,over-
hang the range cooking surface
by 6" on both sides.
CAUTION:
Ventilationhoodsandblowersare
designed for use with single wall
ducting. However, some local
buildingcodesorinspectorsmay
requiredoublewallducting.Con-
sult local building codes and/or
localagencies,beforestarting,to
assure that hood and duct instal-
lation will meet local require-
ments.
• Hood blower speeds should be
variable to reduce noise and loss
of heated or air conditioned
household air when maximum
ventilation is not required. Nor-
mally,themaximumblowerspeed
is only required when using the
grill.
2. Hood Placement:
•Forbestsmokeelimination,the
loweredgeofthehoodshouldbe
installed a minimum of 30" to a
maximumof36"abovetherange
cooking surface. (See Fig. 1).
• If the hood contains any com-
bustible materials (i.e. a wood
covering), it must be a minimum
of36"abovethecookingsurface.
3.ConsiderMake-UpAir:
• Due to the high volume of ven-
tilation air, a source of outside
replacementairisrecommended.
This is particularly important for
tightly sealed and insulated
homes.
•Aqualifiedheatingandventilat-
ing contractor should be con-
sulted.
Page 4
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.

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 Fig. 1 are required. The same clear-
ancesapplytoislandinstallations,exceptforthe
overhead cabinets, which must have a space
wideenoughtoaccepttheflaredislandhood,as
indicated in Fig. 1.
2. The 36" ranges may be recessed into the cabi-
nets beyond the edge of the front face of the
oven (See Figures 2A and 2B).
3. The gas and electrical supply should be within
the zones shown in Fig. 3A.
4. The maximum depth of over head cabinets in-
stalled 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 clear-
ance between combustible material ∆and the
back edge of the range above the cooking
surface, a Thermador Low Back or High Shelf
backguardmustbeinstalled.(SeeFig.2A).When
clearanceto combustible material ∆is over12",
a Thermador Island Trim may be used. (See Fig.
2B). Figures 2A and 2B indicate the space
required for each type of backguard.
7. Always keep appliance area clear and free from
combustiblematerials, gasoline and other flam-
mable vapors and liquids.
8. Do not obstruct the flow of combustion and
ventilation air to the unit.
CAUTION
In these installations, the door and cabinet
can cause a pinching hazard.
NOTE: 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 top of the range and the bottom of an unpro-
tected cabinet. A 30-inch minimum distance is nec-
essary 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:

• Prior to servicing appliance, always disconnect
applianceelectricalsupplycord,ifsoequipped,
from wall receptacle. If appliance is hard-wired
to power supply, disconnect power to unit by
turning off the proper circuit breaker or discon-
necting the proper fuse.
CAUTION
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve
duringanypressuretestingofthegassupplypipingsystemattestpressuresequaltoorlessthan1/2psig(3.5kPa.).
The appliance and its individual shut off valve must be disconnected from the gas supply piping system during
any pressure testing of the system at test pressures in excess of 1/2 psig (3.5kPa.).
Whencheckingthemanifoldgaspressure,theinletpressuretotheregulatorshouldbeatleas6.0"(14.9mb)W.C.
for natural gas or 11.0" (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.
• For the PD Dual-Fuel Ranges, a neutral supply
wire must be provided from the power source
(breaker/fusepanel)becausecriticalrangecom-
ponents, including the surface burner spark
reignition module, require 120 VAC to operate
safely and properly. An improper 120/240 VAC
power supply will cause malfunction, damage
thisappliance,andpossiblycreateaconditionof
shock hazard. If the correct power supply circuit
is not provided, it is the responsibility and obli-
gation of the installer or user to have proper
power supply connected. This must be accom-
plished in accordance with all applicable local
codes and ordinances by a qualified electrician.
In the absence of local codes and ordinances,
the power supply connection shall be in accor-
dance with the National Electric Code.
• Observe all governing codes and ordinances
when grounding. In the absence of these codes
or ordinances observe National Electrical Code
ANSI/NFPA No. 70 Current Issue. See Pages 16
and 8 for grounding method.
• Electrical wiring diagrams and schematics have
been placed in the toe kick area of the range for
access by a qualified service technician.
• The PD Dual Fuel Ranges may be connected to
a 120/208 VAC power supply.
DualFuelrangemodelsPD304,PD36andPD48can
be connected or hard-wired to the power supply as
described on Page 16.

Dual Fuel models must be connected to the power supply utilizing one of the following methods. For all methods of
connection,thelength of the cordorconduit/wiring must allow theunittobe slid completely outofthe cabinet without
havingto unplug ordisconnect the unitfrom the powersupply. Recommended minimumfree length ofcord or conduit
isfour feet. Electricalinstallations and groundingmust be inaccordance with alllocal codes andordinances, and/or the
National Electric Code, as applicable.
