1. Do not install the range hood near open doors and windows to avoid reduced
performance. (Fig.1)
2. Install the range hood directly above the cooktop. The optimal distance between the
cooktop and lower edge of the range hood is 24" to 36". (Fig.2) Install at the height
appropriate to your ceiling. Make sure the chimney reaches the ceiling. If your ceiling
leaves the hood a few inches higher or lower than 24" to 36" you can still install it without a
major loss of performance.
3. For optimal performance, do not over extend the exhaust tube and avoid unnecessary
bending. (Fig.3)
4. After hanging the unit on the wall, ensure the range hood is straight and leveled. (Fig.4)
5. The air outlet must be connected to chimney flumes or combustion gas ducts. Under no
circumstances should the air outlet be connected to ventilation ducts for rooms in which
fuel-burning appliances are installed.

A. Find the Core Unit Bracket (D) that will hold
the back of the range hood. Mark the
locations on the wall with a pencil or marker.
B. Drill a 5/16" (8mm) hole at each marked
location.
C. Insert wall anchors into each hole, gently
tapping in place.
D. Take the Core Unit Bracket ( Part D) that
will hold the range hood and firmly tighten with
3 wood screws (Part B) into the anchors.
Secure range hood by hanging on bracket.
Place the range hood on the wall and mark the
position where you want to install.
A height of 24" to 36" from the cooktop is
recommended for optimalperformance. Install
atthe height appropriate foryour ceiling. You
mayinstall higher if needed. Make sure the
chimney can still reach the ceiling. If your
ceiling leaves thehood afew inches higher or
lower than 24" to 36"you canstill install it with-
outa major loss of performance.
There are 3 included brackets.
Start your measurements from the top down to
make sure the chimney reaches the ceiling with
no gap if desired.
* If you intend to run your ducting through the back wall behind
the hood, it is not necessary for the chimney to touch the ceiling.
