Abstract: A combined log set and gas burner system comprises a plurality of reinforced ceramic fiber burner elements formed in the shape of artificial logs and or glowing embers or a non-porous bed of coals. The burner elements are formed with a gas passageway in the interior of the element and a plurality of gas jets are made which connect the surface of the burner elements to the gas passageway in the burner elements. A source gaseous fluid is connected to the passageways to complete the combination burner system which eliminates the need for a separate burner apart from the log system.

Abstract: A high efficiency gas fireplace unit having a heat exchanger is located in a room in which the heat from the gas fireplace is not wanted. An air duct is connected to the heat exchanger and has a termination point in a room or area remote from the gas fireplace unit. During a heat dump or heat transfer mode of operation, an induced draft fan in an air duct is activated by a remote switch thrown to cause room air to be sucked through the heat exchanger and passed through the air duct and dumped in a remote area so that the fireplace heating effect is nullified or neutralized allowing the fireplace to be operated with or without an air conditioning system.

Abstract: An integrated combined heating and cooling unit comprises a known high efficiency gas fireplace unit stacked on top of a known high efficiency window type air conditioning unit. Novel vent adapters are connected to the rear of the units for connecting them to a source of outside combustion and cooling air to effect high efficiency operations. Novel controls comprise a fireplace relay and an air conditioning relay mounted inside of each of the units. The relays control the on-off operation of the respective units and are actuated by a thermostatic control preferably located remote from the combined units.
