Preparing the installation
4.1 Ductwork preparation
¡The exhaust air is discharged upwards through a duct
or directly through the outside wall into the open.
¡The appliance 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.
¡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.
¡The appliance must be vented to the outside of the
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 “Equivalent duct lengths for commonly used
transitions” table to compute permissible lengths for
duct runs to outdoors. → Page11

4.2 Choosing the correct blower
All blower models are sold separately.
It is recommended to use only Thermador blowers with
Thermador Pro ventilation hoods. See the “Ventilation
Planning Guide” for recommended blowers. Contact
Customer Service for additional options.
→ "Customer Service", Page23
You can purchase integral, in-line and remote blowers
through your authorized Thermador dealer. For local
dealer information, visit the "Find a Dealer" section at
www.thermador.com.
The blower performance options vary in cubic feet per
minute (CFM). The required performance is dictated by
the cooking surface, the volume of air that needs to be
moved and the length 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.
