ABSTRACT:
This device provides a method of automatically extinguishing a fire that may occur in a chimney and it contains an indicating flag that rises when the extinguishing fluid has been discharged onto a fire in the chimney, upon which it is installed. The device includes an elongated and refillable container that is mounted in the top of the chimney, and it further includes a deflector at the bottom, which will create a spray effect when the fluid strikes it.
