TO PERSONS, OBSERVE THE FOLLOWING:
1.  Use this unit only in the manner intended by the manufacturer. If 

you have questions, contact the manufacturer or your distributor.

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 pre-

vent 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 electri-

cal wiring and other hidden utilities.

6.  Ducted fans must always be vented to the outdoors.
7.  To reduce the risk of fire, use only steel 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:
1.  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.

2.  Always turn hood ON when cooking at high heat or when flambe-

ing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef 

Flambe’).

3.  Clean ventilating fans frequently. Grease should not be allowed 

to accumulate on fan or filter.

4.  Use proper pan size. Always use cookware appropriate for the 

size of the surface element.

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.

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.
