WOLF DOWNDRAFT VENTILATION SYSTEMS
DUCTING CONSIDERATIONS
IMPORTANT NOTE:
Always consult a
qualified HVAC Engineer for specific ducting
applications.
Wolf downdraft models with an internal blower
are designed for use with 83 mm x 254 mm
ductwork and 83 mm x 356 mm ductwork for
models with a remote blower. Each can be
transitioned to 203 mm or 254 mm round
ductwork.
For best performance, 254 mm round ductwork
is recommended. The downdraft will operate
most efficiently when the ductwork does not
exceed 12 m in length.
Choose the ducting option that allows the
shortest length of ductwork and a minimum
number of elbows and transitions. Check the
location of floor joists, wall studs, electrical
wiring or plumbing for possible interference
with the ductwork. Refer to the illustrations
below for ducting options.

BLOWER OPTIONS
Wolf downdraft Models ICBDD30I, ICBDD36I
and ICBDD45I include an 850 m3/hr internal
blower. Models ICBDD30R, ICBDD36R and
ICBDD45R are shipped without a blower
assembly and can be used with a 1529 m3/hr
remote blower (812307), available through
your Wolf dealer.
IMPORTANT NOTE:
Blower options vary with
the cooking surface. For recommendations,
refer to the Wolf Design Guide found on the
Wolf website, wolfappliance.com.
IMPORTANT NOTE:
Install this downdraft
ventilation system only with a Wolf blower.
The blower will vary in size and is dictated by
the cooking surface, the volume of air that
needs to be moved and the length of the duct
run. A straight, short duct run with a limited
number of elbows and transitions will allow
the downdraft to perform most efficiently.
A remote-mounted blower will minimize the
amount of blower noise, but will not eliminate
the noise completely.
