Installation Instructions
Installation Considerations
Clearances and requirements
The chimney hood requires the ducting to be vented to
the exterior of the building. It cannot be used in
conjunction with a recirculation unit.
Hood installation height above a cooktop, rangetop or
range can vary. To obtain the necessary installation height
above a cooktop, rangetop or range, consult the
appliance's installation manual.
NOTICE: The hood could incur some damage from heat if
a Thermador Professional®series range or rangetop is
operated with multiple burners at high settings under a
hood that is installed at minimum clearances while the
hood is turned off.
Hood Width
The hood width should be no less than the width of the
cooking surface. For proper performance, the housing
must cover the entire cooking surface.
For proper performance, the hood must be centered
horizontally above the cooking surface. Where space is
not restricted, a wider hood can be used to increase
capture area.
Distance From Cooking Surface
The installation height ranges from a minimum height of
30'' (762 mm) to a suggested maximum height of 40''
(1,016 mm); however, it is necessary to follow the cooking
appliance manufacturer’s installation instructions for
proper hood height.
Unit Weight
This vent hood is heavy. Adequate structure and support
must be provided in all types of installations. When
calculating the load for the housing support system, be
sure to consider the weight of the ventilation unit.
*Follow cooking appliance manufacturer’s recommendations.

of installation, including but not limited to: wall, tile,
mortar, plaster, brick, finishes, partitions, and other
similarly incorporated architectural and structural items.
It is the responsibility of the owner and the installer to
determine if additional requirements and/or standards
apply to specific installations.

Page. 8
Blower Motors
Integral, In-line and Remote blowers are available through
your authorized Thermador®dealer. For local dealer
information, visit the Find a Dealer section of our website
at www.thermador.com.
The blower performance options will vary in cubic feet per
minute (CFM) and is dictated by the cooking surface, the
volume of air that needs to be moved and the length of
the duct run. Refer to the “Blower Motor Installation”
section for detailed blower motor information.
Wall Framing
Due to the weight of the hood, make sure the wood
mounting bracket is attached to all available wall studs.
Framing must be fastened together and to ceiling joists to
provide enough structural strength to support the weight
of the hood and internal blower, if applicable.
Wall framing should be, at minimum, made of 2"x 4"
lumber. Proper structural support is required to
accommodate the weight of the hood.
Electrical Requirements
The unit requires a 120V AC, 60Hz. 15A branch circuit. The
VTR1330 blower in conjunction with a PHxxGWS requires
a 20 amp circuit breaker. The hood should only be
connected to a dedicated circuit (with ground) that has
been installed according to relevant regulations.
When connected to a GFCI-protected supply, Thermador
Professional®hoods are suitable for use in damp locations
that are protected from outside weather conditions and
not subject to saturation with water and other liquids, but
can be subject to moderate degrees of moisture (such as
an outdoor covered patio or lanai area). Refer to local
codes, NEC/CEC, and or the Authority Having Jurisdiction
(AHJ) for additional information.
Check your local building codes for proper method of
installation. In the U.S., this unit should be installed in
accordance with applicable local codes or, in the absence
of local codes, with the National Electrical Code, NFPA 70
or the Canadian Electric Code, CSA C22.1-02.
WARNING
The appliance must be grounded.
NOTE: The 25 ft. Blower Connector Cable accessory
(EXTNCB25W) will only work for distances up to 25 ft.
Accessory cable must be purchased separately. DO NOT
use more than one Blower Connector Cable per
installation.
Electrical Data
Data, including the model and serial number, is located on
the product data rating label inside the appliance, visible
after removal of the filter frame (see “Product Data Rating
Label”).

Ductwork Preparation
Discharge Direction
The exhaust air is discharged upwards through a duct or
directly through the outside wall into the open.
Ducting Recommendations
Proper performance is dependent upon proper ducting.
Local building codes may require the use of make-up air
systems when using ducted ventilation systems greater
than specified cubic feet per minute (CFM) of air
movement. The specified CFM varies from locale to
locale. It is the responsibility of the owner and the installer
to determine if additional requirements and/or standards
apply to specific installations.
DO NOT USE FLEXIBLE DUCT; it creates back pressure/
air turbulence and reduces performance. Always install a
metal vent cover where the ductwork exits the house.
Always install a metal vent cover where the ductwork exits
the house. Hood must be vented to the outside of
building only.
COLD WEATHER installations should have an additional
backdraft damper installed to minimize backward cold air
flow and a nonmetallic thermal break to minimize
conduction of outside temperatures as part of the
ductwork. The damper should be on the cold air side of
the thermal break. The break should be as close as
possible to where the ducting enters the heated portion
of the house.
MAKE-UP AIR: Local building codes may require the use
of make-up air systems when using ducted ventilation
systems greater than specified CFM of air movement. The
specified CFM varies from locale to locale. It is the
responsibility of the owner and the installer to determine if
additional requirements and/or standards apply to specific
installations.
To reduce risk of fire and to properly exhaust air, be sure
to duct air outside. Do not vent exhaust air in spaces with
walls or ceilings or into attics, crawl spaces or garages.
The unit cannot be used in conjunction with a recirculation
unit.
Thermador®recommends not exceeding 50 ft
(15.24 m) equivalent of duct.
Keep duct runs as short and straight as possible. Elbows
and transitions fittings reduce air flow efficiency. Back to
back elbows and “S” turns give very poor delivery and are
not recommended.
A short, straight length of duct at the inlet of a remote
blower gives the best delivery.
Hoods are supplied with a 10" (254 mm) transition. A
locally supplied transition is required for other sizes.
Use the “Equivalent Duct Lengths for Commonly Used
Transitions” table to compute permissible lengths for duct
runs to outdoors.

Choosing the Correct Blower
It is recommended to use only Thermador blowers with
Thermador ventilation hoods. See the Ventilation Planning
Guide for recommended blowers. Contact Customer
Service for additional options (see the back page for
contact information).
IMPORTANT: Cutting off a connector to the appliance,
blower, or to the extension cable kit will void the warranty.
Blower selection will vary based on the volume of air that
needs to be moved and the length and location of the
duct run. For long duct runs with multiple turns and
bends, consider using a more powerful blower. For the
most efficient air- ow exhaust, use a straight run or as few
elbows as possible (refer to “Ductwork Preparation”).
Integral Blowers
These blowers are integrated into the hood at the time of
installation.
Remote Blowers
Depending on preference and ducting situation, these
blowers can be mounted on the roof or exterior wall of the
home. An exterior installation may be more appealing to
reduce noise in the kitchen.
In-line Blowers
To minimize noise in the kitchen, these blowers are
mounted along the duct line anywhere between the
kitchen and the exterior wall. If there is easy access to duct
line (in an attic, for example), this may be an appealing
option.
25 ft. Blower Connector Cable
The 25 ft. Blower Connector Cable Accessory
(EXTNCB25W) is available to connect the hood to the In-
line and Remote Blowers for distances up to 25 ft.
Accessory cable must be purchased separately. DO NOT
use more than one Blower Connector Cable per
installation.
Hood Transition
Discharge Direction
The exhaust air is discharged upwards through a duct or
directly through the outside wall into the open.
The hood can be mounted on the wall only with a vertical
discharge.
Assembly of the Transition
Hoods are supplied with a 10'' (254 mm) round transition.
A locally supplied transition is required for other sizes.
1. A minimum height clearance of 7-7/16'' (189 mm) is
needed above the hood for transition mounting.
2. Align mounting holes at base of transition over the
mounting holes of the 1/2'' (13 mm) flange located at
the top of the hood.
3. Fasten transition to hood using four (4) 1/4'' (6 mm)
sheet metal screws included with hood.
Note: Screws must not hinder damper operation.
4. Seal connection between transition and hood with
aluminum tape. DO NOT use duct tape. Ensure that
the connection is completely sealed.
5. Remove tape holding damper closed.

Wall Mount Installation
The figure below indicates a typical installation of the
hood with an optional chimney extension. Add or subtract
chimney extensions as appropriate to accommodate
ceiling height and recommended hood height.
The installation height is a minimum height of 30''
(762 mm) to a suggested maximum height of 40"
(1,016 mm) for best performance above the cooking
surface; however, it is necessary to follow the cooking
appliance manufacturer’s installation instructions for
proper hood height.
Calculating Optional Chimney Extension
Height
Duct covers, sold separately, are available to cover the
space between the top of the hood and ceiling.
Optional Chimney Extensions are available for purchase in
6'' (153 mm) and 18'' – 35'' (457 mm – 889 mm) sizes.
1. Measure height from floor to ceiling (A, Figure).
2. Measure height from floor to cooking surface (B,
Figure).
3. Measure hood mounting height from the bottom of
hood to cooking surface (C, Figure). Dimension must
be a minimum 30" (762 mm).
4. Calculate optional duct cover height (D, Figure):
D = A – (B + C + 18'').
NOTICE: The hood could incur some damage from heat if
a Thermador Professional series range or rangetop is
operated with multiple burners at high settings under a
hood that is installed at minimum clearances while the
hood is turned off.
Wiring Preparation
Ensure wiring does not interfere with optional chimney
duct cover (where the cover touches the wall).
Ceiling Cutout
The junction box is located on the top right side of the
hood. Wiring should enter at least 20" (508 mm) above
the bottom of the installation height.
Prepare the wire hole cutout in the ceiling, as indicated
below,
with a 5/8'' (16 mm) diameter clearance hole for a
½'' (12.7 mm) conduit to the junction box.

Blower Motor Installation
Blower and Circuit Breaker Ratings
CAUTION
To reduce the risk of fire and electric shock, install this
range hood only with the blowers listed in the
Ventilation Planning Guide.
NOTE: Cutting the plug of the blower will void the
warranty or eligibility for return or exchange.
All blower models are sold separately. Use only
Thermador blowers with these ventilation hoods. See the
Ventilation Planning Guide for recommended blowers.
Contact Customer Service for additional options.
All hood models are rated for 120V AC installed with a
blower listed in the table above, using a 15 amp
dedicated circuit breaker. The VTR1330 blower in
conjunction with a PHxxGWS requires a 20 amp circuit
breaker.
Blower selection will vary based on the volume of air that
needs moved and the length and location of the duct run.
For long duct runs with multiple turns and bends, consider
using a more powerful blower. For the most efficient air
flow exhaust, use a straight run or as few elbows as
possible (refer to
“Ductwork Preparation”).
Integral blower installation
Integral Blower models are integrated into the hood at the
time of installation. Integral Blowers should be installed
after the hood is mounted to the wall.
For complete installation instructions see the instructions
supplied with the blower unit.
1. The blower is attached to the hood using weld studs
on the mounting plate. Guide the motor mounting
plate over the studs.
2. Attach four (4) nuts (included with hood) to the weld
studs. Tighten nuts with a 11/32'' nut driver to secure
the blower to the hood.

Installing a Remote Blower or an In-line
Blower
For complete installation instructions see the instructions
supplied with the blower unit.
Remote Blower
Depending on preference and ducting situation, these
blowers can be mounted on the roof or exterior wall of the
home. An exterior installation may be more appealing to
reduce noise in the kitchen.
In-line Blower
To minimize noise in the kitchen, these blowers are
mounted along the duct line anywhere between the
kitchen and the exterior wall. If there is easy access to duct
line (in an attic, for example), this may be an appealing
option.
Blower Wire Connection
1. Remove junction box channel covering the wires.
2. Remove one circular knockout.
3. Route the blower motor’s plug connector to the hood.
Connect the blower’s harness to the hood harness.
