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 the service disconnecting means 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 accordance 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 equipment
manufacturer’s guideline 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. To reduce the risk of fire, use only metal ductwork.

8. If this unit is to be installed over a tub or shower, it must be
marked as appropriate for the application and be connected to
a GFCI (Ground Fault Interrupter) - protected branch circuit.

9. Never place a switch where it can be reached from a tub or
shower.

10. 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.

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT
OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOW­ING:*

1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or
metal tray, then turn off the burner. BE CAREFUL TO PREVENT
BURNS. If the flames do not go out immediately, 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.

!

WARNING

4. Use an extinguisher ONLY if:
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.
D. You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.

CAUTION

1. For general ventilating use only. Do not use to exhaust hazard-

ous or explosive materials and vapors.

2. To avoid motor bearing damage and noisy and/or unbalanced

impellers, keep drywall spray, construction dust, etc. off power

unit.

3. If ventilator is installed in an unconditioned space (such as

an attic): Surround the ventilator with thermal insulation - to

minimize possible condensation.
