WARNING
To reduce the risk of range top grease fire:
• 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.
• Always turn hood ON when cooking at high heat or
when cooking flaming foods.
• Clean ventilation fans frequently. Grease should not
be allowed to accumulate on fan or filter.
• 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:*
• 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.
• NEVER PICK UP A FLAMING PAN. You may be
burned.
• DO NOT USE WATER, including wet dishcloths or
towels - violent steam explosion will result.
