INSTALL SUPPORT SYSTEM
1. At hood location, install 2 x 4 cross framing
between ceiling joists using dimensions
shown.
2. Finish the ceiling surface. Be sure to mark
the location of the ceiling joists and cross
framing.
3. Position the support frame so that the
support frame openings are on the long
side of the hood and the side with the slot
(A) corresponds to the side opposite the
controls.
4. Secure the support frame to joists and cross
framing with four screws (4,5x60mm) and
washers provided. Make sure screws are
driven into center of joists and framing for
maximum strength.
5. Adjust the overall height of the support
frame. Loosen and re-tighten the screws
in the height adjustment slots as
necessary. Note that the hood height is 14-
3/16" (360mm) and that the bottom of the
hood must be 24" min. and 30" max. above
the cooktop.
