PLANNING DUCTWORK INSTALLATION
PREPARE THE HOOD
In more complex ducting situations, a 3-1/4" x 10" rectangular
ducting range hood (UXT3030AA and UXT3036AA hoods) can be
converted to a round duct by means of a transition.
(This section for UXT2030AA, UXT2036AA, UXT3030AA, and
UXT3036AA hoods only. UXT4030AA and UXT4036AA hoods
skip this section and go on to "Prepare the Hood".)
Begin planning ductwork by deciding where duct will run between
the range hood and the outside. For best performance, use the
shortest possible duct run and a minimum numaber of elbows.
There are several choices shown - FIGS. A - F below.
FIG. A
Ducting directly through the wall (for range hoods mounted on an
exterior wall). Shown are two ways to duct through an outside wall.
If a wall cap is used directly off the back of the hood, special care
must be taken to make sure that the damper in the damper/duct
connector on the hood damper in the wall cap do not interfere with
each other when the hood is operating. This could result in either
inadequate air delivery or backdrafts. If this condition does exist,
remove the hood damper flap. Sometimes when using a wall cap it
is easier to duct vertically and then use an elbow as shown FIG. B.

1. Unpack hood and check contents. You should receive:
1 - Aluminum Filter (UXT3030AA, UXT3036AA, UXT2030AA
and UXT2036AA hoods only)
1 - 3¼" x 10" Damper/Duct Connector (mounted inside of
hood for shipping only) ((UXT3030AA and UXT3036AA
hoods only)
1 - Ductfree Filter (UXT4030AA and UXT4036AA hoods only)
2. Remove wiring box cover. Under cover find:

FIG. E. Ducting between the ceiling joists
(for multi-story installations) or through the
soffit space above the cabinets (where the
soffit connects to an outside wall).
FIG. F. Straight up through the roof
using 6" round duct (for single-story
installations).
