ADVANCE PLANNING
Ductwork Planning
• These vent hoods are equipped for 10” round
ductwork.
• Determine the exact location of the vent hood.
• Plan the route for venting exhaust to the outdoors.
• Use the shortest and straightest duct route possible.
For satisfactory performance, duct run should not
exceed 150 ft. equivalent length for any duct
configurations.
• Refer to “Duct Fittings” chart to compute the
maximum permissible length for duct runs to the
outdoors.
• Use rigid metal ductwork only.
• Install a roof cap with damper at the exterior opening.
Order the cap and any transitions needed in advance.
Ceiling Framing for Adequate Support
• These vent hoods are heavy. Adequate structural
support must be provided. The ceiling structure must
be capable of supporting the weight of the hood and
any inadvertent user contact loads (approximately 300
pounds). The hood support frame will be supported by
2 x 4 cross framing.
Accessory Frames and Duct Covers
• All models are shipped with a support frame and duct
covers for ceilings heights of 7’11" to 8’5".
• Optional accessories include telescoping support
frames and duct covers to reach 8’6” and up to
10’4” ceiling heights.
• Optional accessories must be ordered with the hood
and be on site before final framing and wall finishing.
Mounting the hood without a support frame
The distance between the cooking surface and the
bottom of the hood must be 30" to 36". In situations
where the ceiling is low, the hoods may be secured
directly to the ceiling without the supplied frame.
Use the bottom of the supplied support frame as a
template to locate the mounting holes in the top of the
hood. Use shims on the ceiling joists or cross framing
in the mounting hole locations. This will allow the
mounting screws to engage the recessed keyhole
slots in the top of the hood. See Step 2.

Electrical Supply
This vent hood must be supplied with 120V, 60Hz,
and connected to an individual, properly grounded
branch circuit, and protected by a 15 or 20 amp
circuit breaker or time delay fuse.
• Wiring must be 2 wire with ground.
• If the electrical supply does not meet the above
requirements, call a licensed electrician before
proceeding.
• Route house wiring in the ceiling, as close to the
installation location as possible. Allow additional
length from ceiling joists to reach the junction box
on the bottom of the hood support frame.
• Connect the wiring to the house wiring in accordance
with local codes.
Grounding Instructions
The grounding conductor must be connected to
a ground metal, permanent wiring system, or an
equipment-grounding terminal or lead on the hood.
WARNING:
The improper
connection of equipment-grounding
conductor can result in a risk of electric shock. Check
with a qualified electrician or service representative if
you are in doubt whether the appliance is properly
grounded.
