ABSTRACT:
A chimney fire prevention device and tar trap. The device is seated on the top of a chimney or stove pipe and is comprised of a perforate support for a plastic sheet seal supporting a fire quenching material such as baking soda with sand as a weight agent. The plastic sheet withstands the temperature of normal flue gases but should a chimney fire develop the increased temperature melts the plastic seal and releases the fire quenching material to extinguish the fire. The tar trap is comprised of an open top sleeve on the interior of the device to collect condensed tars to trap the liquid tars or resins from wood fires and can be emptied periodically.
