Fire Safety

Read and save these instructions.

Always have a working smoke detector near the kitchen.

WARNING – TO REDUCE THE RISK OF A 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 flambéing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
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.

In the event that personal clothing or hair catches fire, drop and roll immediately to extinguish flames.

Smother flames from food fires other than grease fires with baking soda. Never use water on cooking fires.

WARNING – TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A GREASE FIRE, OBSERVE THE FOLLOWING:

a) 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.
b) NEVER PICK UP A FLAMING PAN – You may be burned.
c) DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion will result.
d) Use an extinguisher ONLY if:
1) You know you have a Class ABC extinguisher, and you already know how to operate it.
2) The fire is small and contained in the area where it started.
3) The fire department is being called.
4) You can fight the fire with your back to an exit.

Whenever possible, do not operate the ventilation system during a cooktop fire. However, do not reach through fire to turn it off.

Only operate the backsplash ventilation with the florescent lamp fitted.

Use pots which fit the appliance. The top of the pot should not touch the top of the ventilator.
