DECORATIVE HOODS
A decorative 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 measure in multiple
places. Use the smallest dimensions to verify
hood liner specifications.

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: There is a possibility of
noise issues, if there is a short duct run
coupled with a remote blower.
Always install a roof or wall cap if you are not
installing a remote blower. Connect 8" (203)
round metal ductwork for Model L282212I or
10" (254) round metal ductwork for all other
hood liners to the cap and work back towards
the hood. Use duct sealing tape on joints
between ductwork sections.
Wolf Pro hood liners come standard with 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 necessary to 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.

WALL PREPARATION
Construct the wood wall framing flush with
the wall studs and centered in the location
that the hood liner will be mounted. Use
the rough-in plate shipped with hood liner
to determine the location of the framing.
After the wall surface is finished, secure the
rough-in plate assembly to the wall.
Refer to the illustrations below for the location
of mounting holes for Pro hood liners and a
cross-section of a typical installation.
If you are installing LBLOWER-120INT, refer
to the internal blower information on page
11 and follow installation instructions
provided with the blower.
The hood liner assembly is shipped with
the rough-in plate/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. Then take out
the grease cups placed on the bottom edge
of the hood liner coinciding with the bottom
edge of the filters (Model L282212I only).
Gloves should be worn to provide the
proper grip when removing filters.
Detach the rough-in plate/transition
assembly from the hood liner by removing
the screws on the top and back of the
assembly.
Separate the transition from the rough-in
plate by removing the four shipping screws.
Do not discard the screws , they will be
needed to reinstall the transition to the
rough-in plate.
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.
