Abstract: A wood burning stove is configured to produce low emissions and provide high efficiency. The stove includes a housing, a firebox disposed in the housing, a first air flow channel, a secondary air flow channel, and a lower primary air conduit. The secondary air flow channel includes a plurality of secondary air apertures configured to supply secondary air to a combustible gas emitted by a fire. The lower primary air conduit includes a plurality of conduit apertures configured to supply a second primary air flow into the firebox. Also disclosed are methods of operating such a stove.

Abstract: Gas fire devices are provided that produce a swirling flame by passive means using the kinetic energy of gas exiting through burner ports located in a burner and the kinetic energy of air drawn through louvers or flaps radially positioned on the base of a plenum. Situated above the burner and plenum is a chimney, which surrounds the flame and may be a translucent or transparent material to help observers better see the flame.

Abstract: A secure, easy to use and aesthetically appealing outdoor fireplace includes a housing, fuel management component and burner assembly. The fuel management component is disposed alongside the burner assembly and facilitates safe and effective distribution of fuel and dispersion of heat. A roller assembly eases fuel tank transfer while providing stable support, and an outer decorative wall cooperates with the frame platform mounted on the roller assembly to enhance the aesthetic appeal of the fireplace. The fireplace maintains a low profile for stability and aesthetics while properly managing heat so as to avoid damaging supporting surfaces as well as components of the fireplace itself.
