Abstract: A fire extinguishing attachment including a bracket for mounting on a stove stack and having a tubular guide therethrough. The tubular guide is an elbow tube having an inner end within the stack directed towards the chimney flue and an outer end outside the stack adapted to receive the nozzle of a powder type fire extinguisher. When a chimney fire occurs, the extinguisher is placed over the outer end of the guide end and activated. The powdered material is directed, by the guide, into the stack and up the chimney to the location of the fire thereby extinguishing the fire. The guide and bracket is preferably downstream of the damper in the same section of stack to be close to the chimney, and for unobstructed flow.
