Step 1: Ventilation Requirements
It is strongly recommended that a
suitableexhausthoodbeinstalled
above the range. Downdraft
ventilationshouldnotbeused.The
table below indicates the
Thermador hoods, by model
number, that are recommended
for use with all ranges.
1. Select Hood and
Blower Models:
• Forwallinstallations,thehood
width must, at a minimum,
equal the width of the range
cooking surface. Where
space permits, a hood larger
in width than the cooking sur-
face may be desirable for im-
proved ventilation perfor-
mance.
• For island installations, the
hood width should, at a mini-
mum, overhang the range
cookingsurfaceby3"oneach
side.
Notes: * For wall installations where adequate space is available, the installer or user may elect to
use a hood that is wider than the rangetop cooking surface. This may be particularly beneficial
for installations having a long duct run or when heavy usage of the grill is anticipated, in which
improved capturing of the cooking exhaust is desired.
** Thermador offers a choice of remote (VTR1030D or VTR1530D) or internal (VTN1030C)
blowers for use in wall installations.

2. Hood Placement:
• The lower edge of the hood
shouldbeinstalledaminimum
of 36" above the range cook-
ing surface. Also use a 36"
minimumclearanceifthehood
contains any combustible
materialssuchasawoodcov-
ering. (See Figure 1).
3. Consider Make-Up
Air:
• Duetothehighvolumeofven-
tilationair,asourceofoutside
replacement air is recom-
mended. This is particularly
importantfortightlysealedand
insulated homes.
• A qualified heating and venti-
lating contractor should be
consulted.
IMPORTANT:
Ventilationhoodsandblowersare
designed for use with single wall
ducting. However, some local
building codes or inspectors may
require double wall ducting. Con-
sult local building codes and/or
local agencies before starting to
assure that hood and duct instal-
lationwillmeetlocalrequirements.
Do not install a microwave oven /
ventilator combination above the
range, as these types of units do
not provide the proper ventilation
and are not suitable for use with
therange.

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
wide enough to accept the flared island hood as
indicated in Fig. 1.
2. The 36" ranges may be recessed into the cabi-
netsbeyondtheedgeofthefrontfaceoftheoven
(SeeFigures2Aand2B).The30"and48"ranges
are not approved to be installed flush with the
cabinets.
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
thetopoftherangeandthebottomofanunprotected
cabinet. It is recommended that the bottom of the
wood or metal cabinet be protected by not less than
1/4inchofaflameretardantmaterialcoveredwithnot
less than No. 28 MSG sheet steel, 0.015 inch (0.38
mm)thickstainlesssteel,0.024inch(0.6mm)alumi-
num, or 0.020 inch (0.5 mm) thick copper. Flame
retardant materials bear the following mark:

Followed by the flame spread and smoke ratings,
these designations are shown as “FHC (FIame
Spread/SmokeDeveloped).”Materialswith“O”flame
spreadratingsareflameretardant. Local codesmay
allow other flame spread ratings.
3. Thegasandelectricalsupplyshouldbewithinthe
zones shown in Fig. 3A.
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 clear-
ance between combustible material and the
back edge of the range above the cooking sur-
face, a Thermador Low Back or Pot and Pan
Shelf must be installed. (See Fig. 2A). When
clearanceto combustible material is over 12",
aThermador Island Trimmay be used.(See Fig.
2B). Figures 2A and 2B indicate the space re-
quired for each type of backguard.
6. A three (3) inch minimum clearance is needed
whentherange is installed besideacombustible
side wall.
7. Always keep appliance area clear and free from
combustible materials, gasoline and other flam-
mable vapors and liquids.
8. Do not obstruct the flow of combustion and ven-
tilation air to the unit.

Step 8: Door Removal and Installation
To Remove the Oven Door:
• Open the door fully and use a screwdriver to pry the
hinge clips away from the hinge slots. (See Photo
B.)
• Flip the hinge clip toward you. (See Photo C.)
• Close the door until it stops against the hinge clips.
The open hinge clips will hold the door open at a
slight angle.
• Grasp the door firmly on the ends of the door
handle, and lift the door up. (There will be some
spring resistance to overcome.) When the door is
lifted sufficient to clear the hinge hooks, the door
can be pulled straight out. (See Photo D.)
• Place the door in a safe and stable location.
To Reinstall the Oven Door:
• Position the door at a slight angle and insert the
hinges into the hinge slots - one on each side of the
range. The hinges will securely hook into the slots
when properly installed. Do not force, bend, or twist
the door.
Tip: Rest the door on your foot while using your leg for
stability.
• Open the door fully and use a screwdriver to push
the hinge clips all the way into the hinge slots. Be
careful not to scratch the range during this process.
To Check Door Fit and Operation:
• Openandclosethedoorslowlytotestthemovement
andthefitofthedoortotheovencavity.Donotforce
the door to open or close. If the door is properly
installed, it should move smoothly and rest straight
on the front of the range when closed.
• If the door does not operate correctly, verify that the
hinges are properly seated into the hinge slots, and
that the hinge clips are fully engaged into the slots. Photo D. Hinges removed from oven.
CAUTION
USECAUTIONWHENREMOVINGTHE
DOOR.THEDOORISVERYHEAVY.
• Make sure oven is cool and power to oven has
been turned off. Failure to do so could result in
electrical shock or burns.
• The oven door is heavy and fragile. Use both
hands to remove or replace the door.
• Grasp only the ends of the oven door handle.
• Failure to grasp the oven door firmly and properly
could result in personal injury and product
damage.
• With the door off, never release the levers and
try to close the hinges. Without the weight of the
door, the powerful springs will snap the hinges
closed with great force.

Step 9: Burner Test and Adjustment
WHEN FLAME IS PROPERLY ADJUSTED:
• There should be a flame at each burner port.
• Thereshouldbeno air gap betweentheflame
and burner port.
Install any loose components, such as burner caps
and grates that may have been removed earlier. Be
certainthatburnercapsseatproperlyintotheburner
bases. Before testing operation of the appliance,
verify that the unit and the gas supply have been
carefullycheckedforleaksandthattheunithasbeen
connected to the electrical power supply. Turn the
manual gas shut-off valve to the open position.
Test Rangetop Burners
Test Burner Ignition. Select a rangetop burner
knob. Push in and turn counterclockwise to HI. The
ignitor/spark module will produce a clicking sound.
Once the air has been purged from the supply lines,
the burner should light within four (4) seconds.
TestFlame:High Setting.TurnburnerontoHI.See
Figure 9 for appropriate flame characteristics.
Ifanyoftherangetopburnerscontinuetoburnmostly
or completely yellow, verify that the burner cap is
positionedproperlyontheburnerbase,thenre-test.If
flame characteristics do not improve, call
Thermador®.
Test Flame: Low Setting. Turn burner on to LO.
Verifythattheflamecompletelysurroundstheburner.
Thereshouldbeaflameateachburnerportandthere
should be no air gap between the flame and the
burner. If any burners do not carry over, call
Thermador®.
The two far left burners feature XLO®, causing the
flame to cycle on and off when the knob is set to the
XLO range. This is normal operation.
Repeat the Ignition and Flame Test procedures de-
scribed above for each rangetop burner and the grill
burner (if so equipped).
The gas grill uses a tube-style burner that has an air
shutter which allows adjustment to the amount of
primary air inside the burner tube.
Air shutters of tube-style burners are pre-adjusted at
the factory, and usually do not require re-adjustment
except under rare conditions such as installation at
highaltitude.
If grill burner/flame adjustment is required, go to the
procedure: "Flame Adjustment (if necessary)".

Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.

the Flame Adjustment procedure in the following
section.
Test Broil Ignition
Set cooking mode to BROIL. The broil burners will
ignite after 30-75 seconds.
NOTE: Thetwoinfraredceramicbroilburnersdonot

Replace oven bottom cover. Slide cover into place
and reattach to bottom of oven cavity.
Flame Adjustment (if necessary):
Tube-style gas burners used in Thermador© appli-
ances have air shutter systems which are similar to
theillustrationinFigure10,andcanbeadjustedusing
the following method (unless adjustment is not rec-
ommended). It is necessary to remove the burner
from the appliance in order to perform air-shutter
adjustments.
• Loosen shutter screw(s) and turn shutter to new
position.
• Adjust the shutter to more-closed position if the
flame is lifting or blowing, or is not carrying over.
Adjust the shutter to more-open position if the
flame is too yellow. (See Figure 10.)
• Re-tighten the shutter screw(s).
• Afteradjustment,re-installtheburnerandperform
flame evaluation. The air shutter must fit over the
orifice hood for proper operation of the burner.
• Repeat procedure as needed until flame char-
acteristics are acceptable. (See Figure 9.)
