  • FIREPLACE WITH EXHAUST HEAT EXCHANGER
    Publication number: 20090151711
    Abstract: A heat exchanger system and method for transferring heat from exhaust air from a fireplace to air to be delivered to a living space is described. Heated exhaust air is passed through a heat exchanger before exhaustion from the structure. The heat exchanger couples the exhaust duct and the intake duct and transfers otherwise unused heat from the waste products to the outside air to increase the overall efficiency of the heated product source.

  • Pressure relief system for a gas fireplace
    Patent number: 7069925
    Abstract: A pressure relief system for a gas fireplace. The pressure relief system has a flue pipe with an opening in its side. A pressure relief plate is coupled to the flue pipe so that it is movable between an open and a closed state. The pressure relief plate positioned so that it covers the opening in the side of the flue pipe when the pressure relief plate is in the closed state. In the event of a gas explosion, the pressure relief plate is moved to an open state and the pressure build-up in the fireplace is relieved.
