INSTALLATION NOTES
Refer to the illustrations and specifications
for overall dimensions and installation specifics.
Wolf downdraft ventilation systems are
recommended for use with Wolf electric and
gas cooktops and integrated modules, excluding
the grill, steamer and fryer modules. The down-
draft should be at least as wide as the cooking
surface.
IMPORTANT NOTE: Wolf downdraft ventilation
systems cannot be used with Wolf dual fuel
ranges, gas ranges, sealed burner rangetops
and gas rangetops. A Wolf Pro ventilation hood
should be used.
The 45" (1143) downdraft will fit most 45"
(1143) wide cabinets. Cabinet backs may need
to be removed. It is recommended that over-
sized cabinets be used for easier installation.
To incorporate a downdraft system and a
Wolf cooktop, you must allow for a minimum
25
1
/8" (638) 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) of flat countertop
is required behind the cooktop and 1
3
/4" (44) is
necessary between the back edge of the
cooktop and inside of cabinet back. Follow
dimensions given in the Countertop Cut-out
illustration on page 3.
Model DD45I has a 500 CFM internal blower.
Model DD45R is shipped without the blower
assembly. In-line and remote blower assemblies
are available. Blower options vary with the
volume of air that needs to be moved and the
length of the duct run. Refer to the charts at the
end of this section for cooktop ventilation
recommendations and blower options.
IMPORTANT NOTE: Install this downdraft only
with a Wolf blower.
Wolf downdraft ventilation systems require a
separate, grounded 120 V AC, 60 Hz power
supply. The service should have its own 15
amp circuit breaker and a grounded 3-prong
receptacle should be located within the reach of
the 2' (.6 m) power cord. The specific location
of the outlet is not critical, as long as it is
within reach of the power cord that is located
mid-way, top and bottom on the right side of
the downdraft.
If the 45" (1143) downdraft is being installed
in a 45" (1143) wide cabinet, the outlet cannot
be located on the back wall of the cabinet. It is
recommended that the outlet be placed in an
adjacent cabinet within reach of the power
cord. Refer to the Location of Electrical illustra-
tion on page 4.
IMPORTANT NOTE: A ground fault circuit
interrupter (GFCI) is not recommended and may
cause interruption of operation.
You must follow all National Electrical Code
regulations. In addition, be aware of local codes
and ordinances when installing your service.
This appliance must be used with a Wolf
approved remote mounted control module and
top cover, which is included with the down-
draft.
Installation of the control module must be
within 10' (3 m) of the downdraft assembly and
a minimum of 4" (102) from the outer edge of
cooktop element or burner. You will be required
to drill three holes and connect the two units
by the provided wire.
Refer to the installation instructions
shipped with each Wolf product for detailed
specifications.
