Flare-ups are temporary upsurges of flame that result from fat dripping onto hot surfaces or briquettes. All MHP grills have either self-cleaning briquettes, flavor plates or drip pans that help to reduce the chance of flare-ups. Brief flare-ups are normal and usually do not require any action. If one lasts for more than a couple of seconds, carefully move your food and close the lid to kill the flames. DO NOT USE WATER. Flare-ups are a grease fire and using water can increase the flames.
Trimming excess fat off your meats can reduce the chance of flare-ups. If marinating, make sure that it is not dripping off your food, especially if the marinade is mostly oil.
