HOOD PLACEMENT
Wolf cooktop wall and island hoods come with
atelescopic chimney flue that allows you to
reach a ceiling height of 8' (2.4 m) to 9' (2.7 m)
with a finished look. A flue extension to
accommodate 10' (3 m) ceilings is available.
Refer to page 12 for optional accessories.
Installation of the cooktop wall or island hood
should be 24" (610) to 30" (762) from the
bottom of the hood to the countertop.
IMPORTANT NOTE: 8' (2.4 m) ceilings may
not permit installation of the wall or island
hood at 30" (762) above the countertop.
To determine placement of the wall or island
hood, you must calculate the height of the
telescopic chimney flue. Refer to the chart and
illustration below.
IMPORTANT NOTE: Both sections of the
telescopic chimney flue must be installed in
order for the chimney to be lifted for service.

Letters correspond to those in the illustration.
CALCULATE CHIMNEY FLUE HEIGHT
1) First measure A (total kitchen height from
finished floor to finished ceiling height).
2) Next measure B (height from finished floor
to countertop).
3) Then determine the minimum C value
(distance from countertop to bottom of
hood). Refer to the chart below for ceiling
heights from 8' (2.4 m) to 9' (2.7 m).
Dimension
C must be greater than 24" (610)
and less than 30" (762).
4) To determine the upper flue section height:
E=A-(C+B+D) .
IMPORTANT NOTE: If dimension E falls
between 0" (0) and 1/2"(13), you will need to
modify the flue to affix to the flue attachment
brackets. For ease of installation, Wolf
recommends that dimension E be no less
than 1/2"(13).

WALL HOOD INSTALLATION
INSTALL DUCTWORK
IMPORTANT NOTE: Consult a qualified HVAC
Engineer for specific ducting applications.
Decide where the ductwork will run between
the hood and the outside. A straight, short
duct run will allow the hood to perform more
efficiently. 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). Always use metal ducting.
Do not use flex ducting.
IMPORTANT NOTE: All hoods must exhaust
to the outdoors.
IMPORTANT NOTE: Thereis a possibility of
noise issues, when using a remote blower with
ashort duct run.
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. In
cold weather installations a backdraft damper
is necessaryto minimize the backflow of cold
air into the room.
If you are not installing a remote blower,
always install a roof or wall cap. Connect 8"
(203) round metal ductwork to the cap and
work back towards the hood location. Use duct
tape to seal joints between ductwork sections.
Local building codes may require the use of
make-up air. Consult your local HVAC profes-
sional for specific requirements in your area.
Dimensions in parentheses are in

INSTALLATION INSTRUCTIONS
WALL HOOD INSTALLATION
ELECTRICAL REQUIREMENTS
Wolf cooktop wall hoods require a separate,
grounded 110/120 V AC, 60 Hz power supply.
The service should have its own 15 amp circuit
breaker. Locate the electrical supply with a
minimum of 12" (305) of 120 V AC power
cable within the shaded area shown in the
illustration below.
You must follow all National Electrical Code
regulations. In addition, be aware of local
codes and ordinances when installing your
service.
INSTALL BACKSPLASH
If an optional backsplash is to be used, attach
it to the finished wall. Secure the hood
mounting brackets to the wall studs prior to
installing the backsplash.Refer to page 12 for
optional accessories.
INSTALL MOUNTING BRACKETS
Construct wood wall framing that is flush 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 dimensions
shown in the illustration below.
After the wall surface is finished, 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.
Keep in mind that the bottom of the hood
should be 24" (610) to 30" (762) above the
countertop.
Use height adjustment screws to adjust the
hood vertically and the depth adjustment
screws to adjust the hood horizontally.
Securethe 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

CONNECT DUCTWORK
Use the screws and wall anchors provided to
secure the upper brackets to the ceiling.
Position the upper brackets based on the
dimension of the telescopic chimney flue.
Use an 8" (203) round metal duct to connect
the duct collar on the hood to the ductwork
above. Use duct tape to make all joints secure
and air tight.
Connect the upper section of the telescopic
chimney flue to the brackets with the screws
provided.
Nest the bottom of the telescopic chimney flue
into the relief in the hood shell.

WOLF COOKTOP VENTILATION HOODS
Secure the upper half of the support frame to
the joists and cross framing with four screws
provided with your hood. Make sure that the
screws are driven into the center of the joists
and framing for maximum strength. Ensure the
correct orientation of the support frame.
Adjust the overall height of the support frame.
Loosen and retighten the screws in the height
adjustment slots as necessary. Refer to the
illustration below.
IMPORTANT NOTE: The hood height is 111/4"
(286) from the support frame attachment point.
The bottom of the hood must be 24" (610)
minimum and 30" (762) maximum from the
countertop.
CONNECT DECORATIVE FLUE
Securethe upper telescopic chimney flue
section to the upper support frame. Refer to
the illustration below.
Temporarily hold the lower telescopic chimney
flue section over the upper flue section.
ISLAND HOOD INSTALLATION
ELECTRICAL REQUIREMENTS
The Wolf cooktop island hood requires a
separate, grounded 110/120 V AC, 60 Hz power
supply. The service should have its own 15
amp circuit breaker. Locate the electrical
supply with a minimum of 6' (1.8) of 120 V AC
power cable on the ceiling through the top of
the hood.
You must follow all National Electrical Code
regulations. In addition, be aware of local
codes and ordinances when installing your
service.
INSTALL SUPPORT SYSTEM
At the island hood installation location, install
two-by-four or 3/4"(19) plywood cross framing
between ceiling joists. Refer to the island hood
mounting pattern dimensions below.
Finish the ceiling surface. Be sureto mark the
location of the ceiling joists and cross framing.
Determine the desired orientation of the island
hood. Note that the front designates the
control side of the hood.
