Model DD36I 36" (914) downdraft
ventilation system includes a 500 CFM
internal blower. In-line and remote blower
options are available for Model DD36R.
Control module and top cover come in
classic, platinum and carbon stainless
steel finishes.
The cooktop downdraft unit rises from the counter-
top to whisk away odors and smoke into the easy-to-
clean, five-layer mesh filter. The control module and top
cover are available in the exclusive premium finishes of
platinum or carbon stainless steel, or the standard
classic stainless steel for ease in matching your
cooktop.
Wolf downdraft ventilation systems are recommended
for use with Wolf electric and gas cooktops and
integrated modules, excluding the unframed electric
cooktops and electric grill, steamer and fryer modules.
Wolf downdraft systems cannot be used with Wolf
dual fuel ranges, gas ranges, sealed burner rangetops
and gas rangetops.

Refer to the illustrations and specifications
Wolf downdraft ventilation systems require a
for overall dimensions and installation specifics.
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.
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.
If the 36" (914) downdraft is being installed
in a 36" (914) 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.
The 36" (914) downdraft will fit most 36"
(914) wide cabinets. Cabinet backs may need to
be removed. It is recommended that oversized
cabinets be used for easier installation.
IMPORTANT NOTE: A ground fault circuit
interrupter (GFCI) is not recommended and may
cause interruption of operation.
To incorporate a downdraft system and a
Wolf cooktop, you must allow for a minimum
251/8" (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. 23/8" (60) of flat countertop
is required behind the cooktop and 13/4" (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.
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 in the downdraft
control kit, available as a sales accessory.
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.
Model DD36I has a 500 CFM internal blower.
Model DD36R 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.
Refer to the installation instructions
shipped with each Wolf product for detailed
specifications.
IMPORTANT NOTE: Install this downdraft only
with a Wolf blower.
Dimensions in parentheses are in
millimeters unless otherwise specified.

Except for Models DD30I, DD36I and DD45I,
which include a 500 CFM internal blower, Wolf
downdrafts are shipped without the blower
assembly. In-line and remote blower assemblies
are available through your Wolf dealer. To obtain
local dealer information, visit the Locator section
of our website, wolfappliance.com.
Wolf downdraft systems have an adjustable
discharge that will allow you to negotiate
ducting around floor joists and other obstacles.
Three different discharge locations are available
with side to side adjustment for accurate align-
ment of ductwork. Refer to the illustration below
for discharge location options.
IMPORTANT NOTE: Install this downdraft
ventilation system only with a Wolf blower.

For best performance, 10" (254) round ductwork
is recommended. The downdraft will operate
most efficiently when ductwork does not exceed
40' (12 m) in length. Consult a qualified HVAC
engineer for specific ducting applications.
Choose the ducting option that allows the
shortest length of ductwork and a minimum
number of elbows and transitions. Refer to the
illustration below for ducting options.
Refer to the cooktop ventilation charts at the end
of this section for recommendations and blower
options.
IMPORTANT NOTE: All Wolf downdrafts must
be vented to the outside. Use only metal
ductwork.

Planning Information
Wolf Ventilation Recommendations
W O L F B L O W E R A S S E M B L I E S
A ventilation system must include a blower
assembly. With a few exceptions where internal
blowers are included, Wolf ventilation hoods and
downdrafts are shipped without the blower
assembly. An internal, in-line or remote blower
assembly must be selected to accommodate the
cooking appliance, CFM requirements and home-
owner preferences. Internal, in-line and remote
blower assemblies are available as sales acces-
sories through your Wolf dealer.
IMPORTANT NOTE: Use only a Wolf blower
with all Wolf ventilation products.
Internal blowers are mounted inside the hood
canopy or downdraft blower box. In-line blowers
are mounted in between the hood and the
exterior of the home. Remote blowers can be
mounted on the roof or in some cases, on an
exterior wall. Refer to the illustrations below for
dimensions of Wolf in-line and remote blowers.
Ventilation recommendation charts on the
Wolf internal, in-line and remote blowers are for
use with Wolf cooktop hoods, downdraft
systems and Pro ventilation hoods and hood
liners.
following pages provide minimum CFM recom-
mendations according to the cooking appliance
and ventilation system used and blower options
for each specific ventilation hood or downdraft.
