INSTALL SUPPORT SYSTEM

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 as shown. The
UP ARROW should point towards the
ceiling after installation.
4. Secure the support frame to joists and cross
framing with four screws (6x70mm) and
washers provided. Make sure screws are
driven into center of joists and framing for
maximum strength.

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
