ignition – turn the burner down or off.
• Always turn the hood fan ON when part of the cooking surface is
on
• Always make sure the hood grease filter is installed before cooking.
• Clean hood grease filter frequently. Do not allow grease to
accumulate on filter.
• Always use proper pan size. Use cookware appropriate for the size
of the surface element.
• Keep cooking areas clean and clear of combustible materials.
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.

le bruleur plus bas ou l'éteindre.
• Toujours activer le ventilateur de la hotte lorsqu'une partie de la
surface de cuisson chauffe.
• Toujours s'assurer que le filtre de graisse de la hotte est installé
avant la cuisson.
• Nettoyer fréquemment la graisse du filtre de la hotte. Ne pas laisser
s'accumuler la graisse sur le filtre.
• Toujours utiliser la taille appropriée de poêle à frire. Utiliser une
batterie de cuisine proportionnelle à la surface de l'élément.
• Garder propre l'aire de cuisson et dégagée de toute matière
combustible.
Observer les points suivants pour réduire le risque
de blessures aux personnes advenant un incendie de
graisse sur le dessus de la cuisinière :*
• ÉTOUFFER LES FLAMMES à l'aide d'un couvercle ajusté,
d'une plaque à biscuits ou d'un plateau en métal, puis fermer le
brûleur. S'ASSURER D'ÉVITER DES BRÛLURES. Si les flammes
ne s'éteignent pas immédiatement, ÉVACUER LES LIEUX ET
APPELER LE SERVICE D'INCENDIE.
• NE JAMAIS SAISIR UNE POÊLE EN FLAMME. Vous pourriez vous
brûler.
• NE PAS UTILISER D'EAU, ni de linges à vaisselle ni de serviettes
mouillées car il pourrait se produire une violente explosion de
vapeur.
