Installation Preparation

ADVANCE PLANNING
Ductwork Planning
• 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 100 equivalent length for any duct
configurations.
• Refer to “Duct Fittings” chart to compute
the maximum permissible length for duct runs
to the outdoors.
CAUTION:
To reduce risk of fire and to
properly exhaust air, be sure to duct air outside–Do not
vent exhaust air into spaces within walls or ceilings
or into attics, crawl spaces or garages.
PRUDENCE
– Il faut prendre soin
d’installer un conduit vers l’extérieur pour réduire le
risque d’incendie et pouvoir évacuer l’air correctement.
Il ne faut pas évacuer l’air dans l’espace entre les parois
d’un mur, un plafond ou un grenier, un espace sanitaire
ou un garage.
POWER SUPPLY
IMPORTANT – (Please read carefully)
WARNING:
FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE
PROPERLY GROUNDED.
AVERTISSEMENT
POUR DES RAISONS DE SÉCURITÉ, CET APPAREIL
DOIT ÊTRE CORRECTEMENT MIS À LA TERRE.
Remove house fuse or open circuit breaker before
beginning installation.
Do not use an extension cord or adapter plug with this
appliance. Follow National Electrical Code or prevailing
local codes and ordinances.
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.
• Use metal ductwork. These hoods must use 8" round
duct. It can transition to 3-1/4" x 12", reducing the
maximum equivalent duct length to 75 feet.
• Install a wall cap with damper or roof cap at the
exterior opening. Order the wall or roof cap
and any transition needed in advance.
Wall Framing for Adequate Support
• This vent hood is heavy. Adequate structural support
must be provided. The hood must be secured to
vertical studs in the wall, or to a horizontal support.
See page 9.
• We strongly recommend that the vent hood with duct
cover be on site before final framing and wall
finishing. This will also help to accurately locate
the ductwork and electrical service.
• Route house wiring as close to the installation location
as possible in the ceiling or soffit. Wiring should enter
at least 4" above the bracket on the right side.
• 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
the 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.
AVERTISSEMENT
Le mauvais branchement du fil de mise à la terre peut
causer un choc électrique. En cas de doute, consulter un
électricien qualifié ou un technicien pour déterminer si
l’appareil est à la terre.
