LACEMENT
Wolf cooktop wall and island hoods come with a telescopic chimney fl ue that allows you to reach ceiling heights of 8’ (2.4m) to 9’ (2.7m) with a fi nished look.
A fl ue extension to accommodate 10’ (3m) ceilings is available as a sales accessory for cooktop chimney hoods only.
Installation of the cooktop wall or island hood should be
24” (610) to 30” 762) from the bottom of the hood to the countertop.
To determine placement of the wall or island hood, you must calculate the heights of the telescopic chimney fl ue. Refer to the chart in Figure 2-8 above for the minimum and maximum fl ue extension for specifi c hood.
NOTE: Both sections of the telescopic chimney fl ue must be installed in order for the chimney to be lifted for service.
NOTE: If the height of the upper fl ue section is less than 1/2” (13), you will need to modify the fl ue to affi x to the fl ue attachment brackets.

1. Measure A (total kitchen height from fi nished fl oor to fi nished ceiling height).
2. Measure B (height from fi nished fl oor to countertop).
3. Determine the desired distance from counter-top to bottom of hood (C). This dimension must be between
24” (610) and 30” (762).
NOTE: 8’ (2.4m) ceilings may not permit installation of the wall or island hood at 30” (762) above the countertop.
4. To calculate the chimney fl ue height (D): D = A – (B
+ C). This dimension must be between the minimum and maximum fl ue extension for your specifi c hood as shown in the chart.

1. A straight, short duct run will allow the hood to perform more effi ciently.
Limit the number of elbows and transitions to as few as possible. Long duct runs, elbows and transitions will reduce the performance of the hood.
NOTE: All hoods must exhaust to the outdoors.
NOTE: There is a possibility of noise issues, if a short duct run is coupled with a remote blower.
2. Always use metal ducting. Do not use fl ex ducting.
3. Wolf recommends installing a backdraft damper in all installations
(included with hood). In cold weather installations a back-draft damper is necessary to minimize the back-fl ow of cold air into the room.
4. Wolf recommends the hood be installed 24” (610 mm) to 30” (762 mm) above the cooking surface.
NOTE: Local building codes may require the use of make-up air. Consult a local
HVAC professional for specifi c requirements.

EQUIREMENTS
Wolf cooktop wall hoods require a separate, grounded, 110/120 VAC, 60 Hz power supply. The service should have its own 15 amp circuit breaker.
NOTE: You must follow all National
Electrical Code regulations. In addition, be aware of local codes and ordinances when installing your service.

PTIONS
:
1. Ducted Installation.
In a ducted installation, the hood aspirates the kitchen air saturated with fumes and odors, passes it through the grease fi lter(s) and expels it to the outside through ductwork.
For this installation, a hood with an internal, in-line or remote blower can be used. In-line blowers are located in ductwork between the hood and the outside.
For wall hoods, the remote blower can be mounted on the roof or an exterior wall. Wolf in-line and remote blower assemblies are available through your Wolf dealer.
2. Recirculating Installation.
In a recirculating installation, the hood aspirates the kitchen air saturated with fumes and odors, purifi es it through the grease fi lter(s) and charcoal fi lter and returns clean air into the room. For constant effi ciency, the charcoal fi lter must be replaced periodically. For this installation, a recirculation kit available through your Wolf dealer will be required.
NOTE: For Installation instructions for Recirculating Option please see Installation Manual that was provided with the product.

Decide where the ductwork will run between the hood and the outside. A straight, short duct run will allow the hood to perform more effi ciently. Limit the number of elbows and transitions to as few as possible. Long duct runs, elbows and transitions will reduce the performance of the hood. Wolf recommends the maximum linear duct run be no greater than 50’ (15 m).
NOTE: There is a possibility of noise issues, if a short duct run is coupled with a remote blower.
Wolf recommends installing a backdraft damper in all installations. A backdraft damper is included with the hood. It is built into the transition from the hood to the duct run. Unless you are using a remote blower, a roof or wall cap should be installed. Connect ductwork to the cap and work back towards the hood. Use duct tape to seal the ductwork joints.
NOTE: Local building codes may require the use of make-up air. Consult a local HVAC professional for specifi c requirements.
NOTE: Consult a qualifi ed HVAC Engineer for specifi c ducting applications.

NOTE: To install a downdraft system and a
Wolf cooktop, you must allow for a minimum
25-1/8”(638) fl at counter space from front to back. A countertop with a raised lip or backsplash may not allow enough space for proper installation. 2-3/8”(60) of fl at 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.
If downdraft Model DD30 is installed in combination with two cooktops or integrated modules, an integrated module support
(available as a sales accessory) for downdraft ventilation is required. Model DD45 does not require this accessory. If optional fi ller strips are used with the cooktops or modules, be aware that they are different for the Model DD30 and
DD45. Be sure to use the correct fi ller strip.
For installation of a downdraft system with a cooktop, refer to the cooktop installation instructions for the dimensions of the cooktop, countertop cut-out and cabinet requirements.
The depth of the cooktop may vary and will affect the location of the downdraft in the countertop. Figure 2-45 provides countertop cut-out dimensions for downdraft Models DD30,

EQUIREMENTS
Wolf downdraft ventilation systems require a separate, grounded 120 VAC, 60 Hz power supply (for ICB power requirements see Section 6). The service should have its own 15 amp circuit breaker, and a grounded 3-prong receptacle should be located within the reach of the 2-1/2’ (.8 m) power cord. The specifi c 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.
NOTE: If Model DD30 is to be installed in a 30” (762) wide cabinet, Model DD36 in a 36” (914) wide cabinet or Model
DD45 in a 45-1/2”(1156) wide cabinet, the electrical outlet cannot be located on the back wall of the cabinet. The outlet can be placed in an adjacent cabinet within reach of the power cord. An access hole for the power cord must be drilled in the cabinet wall.

THE DOWNDRAFT MUST BE USED WITH A WOLF APPROVED CONTROL MODULE AND TOP COVER.
Installation of the remote-mounted control module can be located anywhere 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 control module to the downdraft assembly using the cable provided.
NOTE: The length of the control module cable is 10’ (3 m). You must plan the installation of the control module to be within 10’ (3 m) of the downdraft assembly.
The remote-mounted control module is 2-3/8” (60) x 6-5/8” (168) and can be positioned horizontally or vertically in the countertop. A 5/8” (16) diameter hole for the DIN connector cable will be centered horizontally and vertically in the back side of the control module. Two 1/4” (6) diameter holes for the mounting screws will be located 2” (51) from the center of the DIN connector cable hole, one on each side. Additional installation instructions are provided with the control kit. Mark the center of the control module on the counter top. Measure 2” (51) up (or left) and 2” (51) down (or right) to locate holes for the mounting screws.

ONSIDERATIONS
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 effi ciently.
A remote-mounted blower will minimize the amount of blower noise, but will not eliminate the noise completely.
NOTE: Blower options vary with the cooking surface. For recommendations, refer to the Wolf
Design Guide found on the Wolf website, www.

ONSIDERATIONS
NOTE: Always consult a qualifi ed HVAC Engineer for specifi c ducting applications.
NOTE: Wolf ventilation downdraft systems must be vented to the outside. Use only rigid metal ductwork.
Wolf downdraft ventilation systems are designed for use with 3-1/4”(83) x 10” (254) ductwork for
Models DD30I, DD36I and DD45I, and 3-1/4”(83) x 14” (356) ductwork for Models DD30R, DD36R and DD45R. Each can be transitioned to 8” (203) or 10” (254) round ductwork.
For best performance, 10” (254) round ductwork is recommended. The downdraft will operate most effi ciently when the ductwork does not exceed 40’ (12 m) in equivalent duct length.
Choose the ducting option that allows the shortest length of ductwork and a minimum number of
Figure 2-46 Top View Installation Dimensions elbows and transitions. Check the location of fl oor joists, wall studs, electrical wiring or plumbing for possible interference with the ductwork.
NOTE: Use duct tape to seal the connection between the blower outlet and ductwork. Support the weight of the ductwork is necessary to ensure sealed joints.
