Abstract: The present invention relates to a gas-fired artificial log stove assembly, and more particularly to a gas stove assembly which visually simulates, in a realistic fashion, a traditional fire in a gas-fired stove stacked with horizontally disposed artificial logs, and which at the same time supplies substantial space heat to the surrounding room environment by heating room air circulated through a heat exchange mechanism.

Abstract: In a fireplace unit having an open sided firebox formed by opposed side walls, a top wall, a bottom wall, a rear wall, and a connection in the top wall to an exhaust flue, the present improvement including an intermediate wall member of overall curved configuration mounted in the firebox opening, the intermediate wall member being spaced from the rear wall of the firebox and extending between the opposed side walls and, at least, the bottom wall thereof to define a substantially enclosed space in the firebox opening therebehind, the curved configuration of the intermediate wall member increasing the reflective and radiant characteristics of the interior of the firebox thereby improving its overall efficiency and heat transfer capabilities. The various embodiments of the intermediate wall member disclosed herein may be attached to the firebox by fasteners, by welding, or by other suitable arrangements, or such intermediate wall member may be integrally formed as part of the firebox itself.

Abstract: A gas fire space heater which can be an insert for an existing fireplace or a free standing unit is described. The device consists of a gas burner with radiants disposed within a housing. The products of combustion are collected in a first plenum, directed through a concertina heat exchanger into a second plenum, and from the second plenum up a flue. Air to be heated is collected by a blower and circulated countercurrently to the products of combustion through the heat exchanger, around the housing, and into the space to be heated. Air to be heated is supplied to the blower from an outside vent, and an inside vent. The outside vent is controlled by a one-way suction damper and the inside vent is controlled by a manual damper. The two vents form a T at the fan inlet and control of the manual damper then controls the amount outside and inside air supplied to the blower.

Abstract: Heating stove which permits essentially two modes of combustion: (a) upwards combustion i.e. with combustion air entering from beneath the grates. (b) downwards from the combustible material i.e. the combustion air enters from above the hearth so that the combustion gases pass downwards through the grates. The modes of combustion being regulated by a device of flaps.

Abstract: A forced air gas fired heating device may be utilized as a stove insert for a conventional open fireplace or in an alternative embodiment may be formed with a double walled construction for use as a free standing unit. In both embodiments a gas burner adjacent a bottom portion of the housing heats an air space within the housing. A room air inlet conduit traverses back and forth across the heated air space and communicates with an air distribution chamber in an upper portion of the housing. A plurality of room air outlet conduits extend outwardly from the distribution chamber through a front wall of the housing. A heat exchanger is suspended from each of the room air outlet conduits and includes a hollow body portion in fluid communication with the associated air outlet conduit. Each of the heat exchangers has an enclosed longitudinally extending corrugated heat conductive metal plate and terminates in a bottom heat conducted metal plate deposed adjacent the gas burner.

Abstract: A combustion apparatus including a housing formed with an opening, a combustion tube provided in the opening, a reflector disposed rearwardly of the combustion tube, and at least one heat shielding plate disposed between the combustion tube and a top plate of the housing such that at least one gap for allowing convected air to flow therethrough is defined between the heat shielding plate and the top plate. Furthermore, a front end of the heat shielding plate is projected forwardly of the top plate.
