HOOD PLACEMENT
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.

CALCULATING CHIMNEY FLUE HEIGHT
Measure A (total kitchen height from fi nished fl oor to 1.
fi nished ceiling height).
Measure B (height from fi nished fl oor to countertop). 2.
Determine the desired distance from counter-top to 3.
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.
To calculate the chimney fl ue height (D): D = A – (B 4.
+ C). This dimension must be between the minimum
and maximum fl ue extension for your specifi c hood as
shown in the chart.

CT WALL HOOD INSTALLATION CONSIDERATIONS
TO REDUCE THE RISK OF FIRE, USE ONLY RIGID METAL DUCTWORK.
TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK, THIS VENTILATION HOOD SHOULD ONLY BE
INSTALLED WITH BLOWERS MANUFACTURED BY WOLF APPLIANCE INC. AND SPECIFIED FOR USE WITH
THESE VENTILATION MODELS.
COUNTERTOP WALL HOODS INSTALLATION
SPECIFICATIONS AND PREPARATIONS FOR
MODELS CTWH30 & CTWH36
A straight, short duct run will allow 1.
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.
Always use metal ducting. Do not 2.
use fl ex ducting.
Wolf recommends installing a back-3.
draft 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.
Wolf recommends the hood be in-4.
stalled 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 require-
ments.
ELECTRICAL REQUIREMENTS
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.

CT WALL HOOD INSTALLATION
DUE TO THE WEIGHT OF SOME HOODS, SEVERAL
PEOPLE MAN BE REQUIRED FOR A SAFE AND
PROPER INSTALLATION.
INSTALL MOUNTING BRACKETS
Construct wood wall framing that is fl ush with the interior
surface of the wall studs. Make sure that the framing is
centered in the hood installation location, and that the
height of the framing will allow the mounting brackets to
be secured to the framing within the dimension shown in
Figure 2-10.
After the wall surface is fi nished, secure the mounting
brackets to the framing using the dimensions shown.
INSTALL THE HOOD
Hang the hood from the brackets through the rectangular
cut-outs on the back of the hood. The cut-outs are larger
than the brackets to allow for vertical and horizontal
adjustment. (See Figure 2-11)
Keep in mind that the bottom of the hood should be 24”
(610) to 30” (762) above the countertop.
Figure 2-10 Mounting Bracket Installation
TO REDUCE THE RISK OF ELECTRICAL SHOCK,
THIS VENTILATION HOOD MUST BE PROPERLY
GROUNDED.
Use height adjustment screws to adjust the hood vertically
and the depth adjustment screws to adjust the hood
horizontally.
Secure the hood with additional mounting screws. If wall
studs or framing are not available in the proper location,
use the drywall anchors provided with the hood.
ELECTRICAL CONNECTIONS
NOTE: This unit should be install by a qualifi ed electrician
in accordance with all applicable national and local codes.
Remove the cover from the rear electrical box knockout 1.
that faces the hood’s discharge collar.
Insert 6” (152) of 120 VAC power cable through the 2.
knockout opening. Secure the cable to the electrical
box with an appropriate connector.
Make electrical connections. Connect black to black, 3.
white to white and green/yellow to green or bare wire.
(See Figure 2-12)
Reinstall the electrical box cover and screws. Make 4.
sure that all wires are secure and that no wires are
pinched between the cover and box.

CTE WALL HOOD INSTALLATION CONSIDERATIONS
TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.
TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK, THIS VENTILATION HOOD SHOULD ONLY BE
INSTALLED WITH BLOWERS MANUFACTURED BY WOLF APPLIANCE INC. AND SPECIFIED FOR USE WITH
THESE VENTILATION MODELS.
INSTALLATION OPTIONS:
Ducted Installation. 1.
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.
Recirculating Installation.2.
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.
LOW-PROFILE HOOD INSTALLATION SPECIFICATIONS AND PREPARATIONS
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.

DOWNDRAFT INSTALLATION SPECIFICATIONS
INSTALLATION SPECIFICATIONS
Wolf downdraft Model DD30 will fi t most 30”
(762) wide cabinets, Model DD36 will fi t most
36” (914) wide cabinets and Model DD45 will
fi t most 45-1/2”(1156) wide cabinets. It is
recommended that oversized cabinets be used
for easier installation. Cabinet backs may need
to be removed. Wolf downdraft ventilation
systems can be mounted in an island, peninsula
or standard wall location.
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
