An automatically activated fire extinguishing device for a stove. The device (10) is installable in a hood (16) over the stove (11) and has a compact design which substantially hides portions of the device from normal viewing. A container (12) holds the fire extinguishing compound and is evacuated when valve (22) punctures seal (21) in the container opening (20). A tube (24) conveys the compound from valve outlet (25) to header (26) when valve (22) is open. Nozzles (28) secured to header (26) direct the compound to the stove surface (30). Fusible links (36), trigger (37) and wires (38) activate a valve opening mechanism (40) when link (36) breaks pushing rod (41) of valve (22) upwards to puncture seal (21). The invention also includes an automatic stove shut-off (44) which shuts off the electricity or gas to the stove in the event of a fire.
