READ AND SAVE THESE INSTRUCTIONS

INSTALLATION PRECAUTIONS

e high degree of craftsmanship in the construction and finish
of your hood requires careful handling to ensure proper
installation.

• Do not remove your hood from its carton until you are ready
to hang it.

• Do not store your hood anywhere other than within the carton.
If it is necessary to remove your hood from the carton, arrange
it on a blanket or padded area that will protect your hood
from scratches or indentations.

• Do not lift the hood by its utensil rail. Place your fingers under
the lower reveal of the hood. Grasp firmly and lift.

• Cotton gloves are preferable. ey will protect the surface
from fine scratches and eliminate fingerprints.

• Remove all rings, watches, belt buckles, and jackets
(snaps-zippers) to prevent scratch marks.

• Do not remove the cotton flannel from your hood until
the installation process is complete. It will be necessary
to remove only a small portion on the back-side of a wall
mounted hood in order to position in place.

• Located within the hood cavity (behind the baffle filter)
are component parts and halogen bulbs.

INSTALLATION PLANNING

CHECK THE INSTALLATION LOCATION

• If your installation has been roughed-in (including ductwork and
wiring), be certain there are no obstructions in the way of the
mounting, pipes, other wiring, etc.

• If the installation has not been roughed in, check what is needed
to create the framing and mounting hardware (allthreads, nuts,
etc.). Be sure the location will not interfere with wiring, other
utilities, or structural considerations.

WALL MOUNTED HOODS

1. Use 2x4s, Unistrut or Angle Iron, to construct the framing. e considerable
weight of the hood makes this necessary.

2. Mark the center location of the hood. Install two 2x4s (wide side down),
Unistrut or Angle Iron, across ceiling joists with outer edges aligned with
the existing ceiling joist.

3. Drill two 7/16"" diameter holes in the 2x4s, Unistrut or Angle Iron, the
same distance apart as the nuts in the top of the hood, plus the finished
drywall thickness. is ensures the hood is tightly fitted against the wall.
Install wooden spacers if necessary to ensure the top of the hood is flush
with the ceiling.

CHOOSE THE INSTALLATION METHOD

ere are several different methods available to mount the hood: the
Unistrut, Angle Iron, Frame In, Wall Mount and Rough-In Plate Mount,
which can be used for both indoor and outdoor applications. Please check
the model options for the suggested methods of your installation. Each
hood type and site requirements are presented as follows.

5. While lifting the hood, guide and position the allthread through the
2x4s, Unistrut or Angle Iron, (At least 2 people are recommended
for this step)

7. Secure the hood with 3/8" nuts (do not tighten).

8. Adjust hood to proper location and tighten nuts. A second nut should
be used as a locknut

9. Locate studs and drill 3/8" diameter holes through back panel. Secure
hood to wall with (4) 1/4" x

10. Connect the duct to hood using 3 sheet metal screws and seal all joints
with silicone or duct tape.

11. Make electrical connections. (An electrical contractor should make
all electrical connections. See wiring diagram.)
