A fire extinguishing system is automatically actuated in response to flames from a fire on the upper surface of a stove having a vent hood. A pressurized fire extinguisher includes a lever actuated valve spring biased to the open position and contains a supply of fire extinguishing material. A discharge manifold extends between the valve of the fire extinguisher and a plurality of nozzles which are positioned within the vent hood to distribute the fire extinguishing material over the upper surface of the stove when the valve is released into the open position. A fusible link secures a strut which maintains the valve in a closed position. A fuse extends from an area above the upper surface of the stove to a capsule of gun powder which surrounds the fusible link. A fire in the stove top area ignites the exposed end of the fuse which controllably transfers fire to the capsule of gun powder. Combustion of the gun powder instantaneously severs the fusible link which releases the strut and permits the spring to open the valve of the fire extinguisher causing the entire contents of the fire extinguisher to be discharged onto the stove top area.
