PLANNING AND
DESIGN INFORMATION
The downdraft ventilation system
should be at least as wide as the
cooking surface you are designing
into the home.
The 30" (762 mm) downdraft will fit
most 30" (762 mm) wide cabinets
and the 36" (914 mm) downdraft will
fit in most 36" (914 mm) wide
cabinets. Cabinet backs may need to
be removed. It is recommended that
oversized cabinets be used for easier
installation.
IMPORTANT NOTE: To incorporate
a downdraft system and a Wolf
cooktop, you must allow for a
minimum 25-1/8" (638 mm) flat
counter space from front to back. A
countertop with a raised lip and/or
backsplash may not allow enough
space for proper installation. 2-3/8"
(60 mm) of flat countertop is
required behind the cooktop and
1-3/4" (44 mm) is necessary between
the back edge of the cooktop and
inside of cabinet back. Also, the
cabinet back may need to be
removed.
When installing cooktop service
connections, you MUST use adjacent
base cabinets outlined in the cooktop
specifications.
Except for Models DD30I and DD36I,
downdrafts are shipped without the
blower assembly. The blower or venti-
lator will vary in size and is dictated
by the cooking surface and the
distance to the exterior of the home.
The blower assemblies are quite
varied, and depending on the
amount of air you want to move and
the length of the duct run, you have
many options.

You also need to consider if you are
going to use these assemblies as
internal blowers or mount them
externally.
