Choosing The Correct Blower; Attaching The Hood Transition; Wall Mount Installation - Thermador HPCN36WS Installation Instructions Manual

Choosing the correct blower

Blower motors
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 (see the back page for contact
information).
Integral, in-line and remote blowers are available through
your authorized Thermador
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. 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").

Calculating the installation 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. (See figure below.)
