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 downdraft 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 oversized 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 illustration 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 downdraft.
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.
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.
IMPORTANT NOTE: Install this downdraft ventilation system only with a Wolf blower.
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 alignment of ductwork. Refer to the illustration below for discharge location options.

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.
IMPORTANT NOTE: All Wolf downdrafts must be vented to the outside. Use only metal ductwork.
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.

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 homeowner preferences. Internal, in-line and remote blower assemblies are available as sales accessories through your Wolf dealer.
Wolf internal, in-line and remote blowers are for use with Wolf cooktop hoods, downdraft systems and Pro ventilation hoods and hood liners.
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 following pages provide minimum CFM recommendations according to the cooking appliance and ventilation system used and blower options for each specific ventilation hood or downdraft.
