Electrical requirements

9 WARNING
The appliance must be grounded.
The unit requires a 120V AC, 60Hz. 15A branch circuit.
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
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. 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.
The 25 ft. remote and in-line blower extension cable
accessory (EXTNCB25W) will only work for distances
up to 25 ft. The accessory cable must be purchased
separately. DO NOT use more than one blower
extension 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" on page 17").

Ductwork preparation

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.
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.

hoods are suitable for use in
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.

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 "Attaching the hood transition" table to
compute permissible lengths for duct runs to
outdoors.
