Abstract: A combustion air and exhaust gas balancing system for use with a direct-vent heater appliance. The balancing system includes a combustion air valve in fluid communication with a combustion air duct and an exhaust gas valve in fluid communication with an exhaust gas duct. The combustion air valve is operatively coupled to the exhaust gas valve with an actuator. The combustion air and exhaust gas valves are shaped and sized so that a single operation of the actuator simultaneously adjusts the flow of combustion air into the firebox and the flow of exhaust gas out of the firebox and provide selected flame characteristics in the firebox. In one aspect of this embodiment, a movement of the actuator in a first direction simultaneously increases the flow of combustion air and exhaust gas, and a movement of the actuator shaft in a second direction simultaneously restricts the flow of combustion air and exhaust gas.

Abstract: An electric fireplace assembly is disclosed and discussed. An electric fireplace of an embodiment includes a housing, a screen assembly having a translucent picture or image, a light panel behind the screen assembly, a controller coupled to the light panel, an image plate behind the screen assembly, and a reflector assembly above the light panel and behind the screen assembly.

Abstract: A burner assembly that overcomes problems experienced in the prior art. One embodiment provides a burner assembly for burning a fuel gas from a gas source. The assembly has a burner body with a contoured upper surface and a burner pan with a gas inlet aperture therein. The burner body is connected to the burner pan. The burner body and burner pan are spaced apart to form a gas distribution chamber therebetween. The burner body has a plurality of gas apertures extending between the distribution chamber to an upper surface of the burner body. The gas apertures are positioned to allow the fuel gas to flow to selected areas on the burner body's upper surface for combustion to create a desired flame at selected locations relative to the upper surface. In one embodiment is a contoured upper surface with a plurality of peaks and valleys forming simulated coal or ember members.

Abstract: A device for the ornamental display of the interaction of fire and water allowing the spray of a water fountain to be combined with flame from a gas burner is described. The device includes one or more gas burners configured amongst one or more water dispersion assemblies. The water streams from the nozzles of the water dispersion assemblies of the fountain can be directed toward, through, and over the flames originating from the gas burners. The flames originating burners are protected from being extinguished by a water shield. The water shield is positioned in such a manner to influence the characteristics of the flame produced by the burner while still protecting the flames' integrity. The water and fire aspect of the device can operate independently providing a fire source with a reflecting pool or a water fountain absent the flames.

Abstract: Wood burning stove having several features for reducing emissions output and for improving energy efficiency by increasing the supply of oxygen to combustible materials, by increasing the mixing of oxygen with combustible materials, and by lengthening the residence time of combustible materials within the stove. The features include a turbulence-creating means positioned at an upper, front region of the combustion chamber, and a baffle located near the outlet for increasing both turbulence and the pathway of combustible materials exiting the stove.
