leads.
2. Connect the aluminum wiring to the added section of
copper wire using special connectors
and/or tools
designed and UL listed for joining copper to aluminum.
Follow the electrical connector manufacturer's
recommended
procedure. Aluminum/copper

INSTALLATION INSTRUCTIONS
It is recommended
that the vent system be installed before
hood is installed.
•
Before making cutouts, make sure there is proper clearance
within the ceiling or wall for exhaust vent.
•
We recommend
the hood be installed 30"to 36" (76.2 cm to
91.4 cm) above the countertop.
•
Check your ceiling height and the hood height maximum
before you select your hood.
•
To avoid damage or dirt, place a thick, heavy covering over
countertop,
cooktop, or range.
1. Disconnect
power.
2. Determine which venting method to use: roof, wall, or non-
vented.
3.
Select a flat surface for assembling
the range hood. Place
covering over that surface.
NOTE: Do not remove the plastic covering on the chimney
covers at this time. The covering protects the chimney during
installation.
Excessive Weight Hazard
Use two or more people to move and install
range hood.
Failure to do so can result in back or other injury.
4.
5.
Using 2 or more people, lift range hood onto covered surface.
Determine and mark the centerline on the ceiling where the
hood will be installed, making sure that the hood is centered
over the cooking surface.
