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.
