ELECTRICAL REQUIREMENTS
Wolf Pro ventilation hood liners 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 within the shaded area shown in the
Installation Specifications illustration on
the following page.
You must follow all National Electrical Code

DECORATIVE HOODS
Adecorative hood can be created out of wood,
plaster, tile or metal. The shape of the decora-
tive hood is not critical. The only place where
the hood liner and outside cover must meet is
at the bottom edge of the liner. The decorative
hood and liner must fit at the bottom edge in
both width and depth.
The height of the hood liner does not have to
be the same as the height of the decorative
hood and is generally shorter.
The top depth of the hood liner, which is 12"
(305) standard, must be less than the interior
depth of the decorative hood. Measure the
interior depth of the hood at the top height of
the liner to make sure the liner will fit inside
the decorative hood.
The hood liner comes standard with a 4" (102)
lower reveal. Be sure to include this dimension
in your decorative hood selection.
Always use the interior measurements of the
decorative hood and measurein multiple
places. Use the smallest dimensions to verify
hood liner specifications.

INSTALL DUCTWORK
IMPORTANT NOTE: Wolf recommends that
the Pro ventilation hood liner be installed
30" (762) to 36" (914) above the countertop.
IMPORTANT NOTE: Consult a qualified HVAC
Engineer for specific ducting applications.
IMPORTANT NOTE: All Wolf ventilation hood
liners must exhaust to the outdoors. Always
use metal ducting. Do not use flex ducting.
Decide where the ductwork will run between
the hood liner and the outside. A straight,
short duct run will allow the hood liner 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 liner. Wolf
recommends the maximum linear duct run be
no greater than 50' (15 m). The Pro hood liner
has a vertical discharge.
IMPORTANT NOTE: Thereis a possibility of
noise issues, if thereis a shortduct run
coupled with a remote blower.
Always install a roof or wall cap if you are not
installing a remote blower. Connect 10" (254)
round metal ductwork to the cap and work
back towards the hood. Use duct sealing tape
on joints between ductwork sections.
Wolf Prohood liners come standardwith a
backdraft damper included in the transition
assembly.Local codes may require the use of
an additional backdraft damper.Contact your
local HVAC professional for specific require-
ments. In cold weather installations, a back-
draft damper is necessaryto minimize the
backflow of cold air into the room.
Local building codes may require the use of
make-up air. Consult your local HVAC profes-
sional for specific requirements in your area.
To reduce the risk of fire, use only metal
ductwork.
To reduce the risk of fire and electric
shock, install this ventilation hood liner
only with a blower manufactured by
Wolf. Blower model numbers are listed
on page 14.

WOLF PRO VENTILATION HOOD LINERS
WALL PREPARATION
Construct the wood wall framing flush with
the wall studs and centered in the location
that the hood liner will be mounted.
Refer to the illustrations below for the location
of mounting holes for Pro hood liners and a
cross-section of a typical installation.
HOOD LINER PREPARATION
If you are installing LBLOWER-120INT, refer
to the internal blower information on page
11and follow installation instructions
provided with the blower.
The hood liner assembly is shipped with
the transition attached. The transition is
shipped upside down in the top of the hood
liner. It must be removed and reinstalled in
the proper position. Refer to the illustration
on the following page.
Remove the filters by pushing each filter up
at the angle it is placed in, and rotate down.
Remove the center filter first. Gloves should
be worn to provide the proper grip when
removing filters.
Separate the transition from the top plate
by removing the four shipping screws.
Do
not discard the screws
,they will be
needed to reinstall the transition to the top
plate.
Attach the transition to existing ductwork
with sheet metal screws and duct sealing
tape.
Framing must be tied together and to
ceiling joists to provide enough structural
strength to support the weight of the hood
liner and internal blower, if applicable.

INSTALLATION INSTRUCTIONS
HOOD LINER PREPARATION
If you are installing an in-line or remote
blower, drill a 7/8"(22) hole through the
wood framing for the conduit. Refer to the
in-line and remote blower information on
pages 12–13 and follow installation instruc-
tions provided with the blower.
IMPORTANT NOTE: Donot run wiring for the
remote blower through the ductwork.
INSTALL THE HOOD LINER
IMPORTANT NOTE: If a backsplash is to be
used, it should be installed before the hood
liner is mounted.
Position the hood liner in the desired location
on the wall. Install the #10 x 2" (59) screws
through the mounting holes on the back plate.
Verify that the screws engage the wall studs or
framing. If not, wall anchors must be used.
IMPORTANT NOTE: If additional support is
required for the hood liner, drill supplementary
mounting holes in the back plate and use these
holes to attach the hood liner assembly to the
wall framing.
Due to the weight of the hood liner, be
sure to have adequate manpower for
installation.

Run a 120 V AC, 15 amp circuit (minimum)
power cable from the service panel to the
electrical box in the back of the hood liner.
Insert the conduit through the holes in the
back of the hood liner to the electrical box.
Remove the electrical box cover from the
back of the hood liner. Connect black wire
to power supply black wire, white wire to
power supply white wire and green wire to
green wire or bare wire.
Place all wiring connections inside the
electrical box and reinstall the electrical box
cover. Make sure that the wires are secure
and that no wires are pinched between the
cover and box.
Refer to the wiring diagram packaged with the
hood liner for more information.
