This range hood can discharge upward
or backward. According to the conditions
where the hood is installed, determine
whether it will be discharged vertically or
horizontally (3 1/4” x 10” duct). For
vertical or horizontal discharge, run duct
work between the hood location and the
roof cap or wall cap.
For best result in either direction, use a
minimum number of transitions and
elbows. Be sure to attach a roof cap or
wall cap to avoid rain/wind entry.

The range hood unit must be mounted to a liner which has the
following dimensions. Install the liner securely after checking that
the opening size of the liner is the same as the figure below.
• If the range hood is not installed properly, it could become detached
and fall.
• Ensure that the metal duct does not touch other metal housing
materials, otherwise fire or electric shock could result.
• When the liner is installed in the wooden hood, the inside of the
wooden hood placed above the cooking surface must be fully
covered by the metal barrier including bottom edges. Select a
suitable liner and metal barrier according to the size and shape of
the wooden hood and install properly.
• The liner should be installed tightly. If the liner installation is not
correct, the range hood unit may become detached and fall off.
• Wear working gloves to avoid injury.
