WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If you have questions,
contact the manufacturer at the address or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel and lock service
panel to prevent power from being switched on accidentally. When the service
disconnecting means cannot be locked, securely fasten a prominent warning device,
such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by a qualified person(s) in accor-
dance with all applicable codes and standards, including fire-rated construction codes
and standards.
4. Sufficient air is needed for proper combustion and exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equip-
ment manufacturer’s guidelines and safety standards such as those published by the
National Fire Protection Association (NFPA), and the American Society for Heating,
Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other
hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Do not use this unit with any separate solid-state speed control device.
8. To reduce the risk of fire, use only metal ductwork.
9. This unit must be grounded.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
A. Never leave surface units unattended at high settings. Boilovers cause smoking and
greasy spillovers that may ignite. Heat oils slowly on low or medium settings.
B. Always turn hood ON when cooking at high heat or when flambeing food (i.e. Crepes
Suzette, Cherries Jubilee, Peppercorn Beef Flambe’).
C. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or
filter.
D. Use proper pan size. Always use cookware appropriate for the size of the surface
element.

EVACUATE AND CALL THE FIRE DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN - You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels - violent steam explosion will
result.

A. You know you have a Class ABC extinguisher and you already know how to operate
it.
B. The fire is small and contained in the area where it started.
C. The fire department is being called.

INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only
metal ductwork.
1.Decide where the ductwork will run between
the hood and the outside.
2. A straight, short duct run will allow the hood
to perform most efficiently.
3. Long duct runs, elbows, and transitions will
reduce the performance of the hood. Use
as few of them as possible. Larger ducting
may be required for best performance with
longer duct runs.
4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back to-
wards hood location. Use duct tape to seal
the joints between ductwork sections.
