Abstract

A burner apparatus for an indoor or outdoor fireplace, fire pit, stove or oven is shown. The burner apparatus operates to produce natural gas fueled or liquid petroleum fueled amber flames among artificial logs, coals or a combination of artificial logs and coals, simulating a natural fire. One embodiment of the burner apparatus comprises a burner tube loop for the distribution of fuel, a fuel/air mixing valve for mixing the fuel and air before ignition of the resulting fuel/air mixture, metal cups for the dissipation of the fuel/air mixture and flames, an ignition system for igniting the fuel/air mixture, a control system for monitoring and controlling the ignition of the fuel and for regulating the flow of fuel, and artificial logs, coals or a combination of logs and coals placed around the burner tube loop to provide for an aesthetically pleasing and natural looking display.
