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
®
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. 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”).
Blower options
25 ft. remote and in-line blower extension cable
The 25 ft. remote and in-line blower extension cable
(EXTNCB25W) is available to connect the hood to the in-
line and remote blowers for distances up to 25 ft. The
accessory cable must be purchased separately. DO NOT
use more than one extension cable per installation.
Attaching the 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.
Attaching the hood 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 6½'' (165 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. Secure the transition to the hood using four (4) 1/4'' (6
mm) sheet metal screws included with hood.
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.
