ABSTRACT:
A combination damper and chimney cap apparatus is provided to ventilate a fireplace and a flue connected thereto to provide a draft through the flue. The apparatus includes a platform constructed and arranged to be removably mounted to the flue and formed with an aperture extending therethrough in communication with the flue. An element senses temperature-smoke at the flue and at an area external to a fireplace connected to the flue to provide a signal in response to the temperature-smoke. A ventilation fan is connected to the a support to provide a draft sufficient to exhaust the smoke from the fireplace and the flue and to cool a electronic motor for the apparatus.
