The invention provides a method for reconfiguring a burner assembly having an air register, a central burner tip adapted to burn fuel oil, and a plurality of peripheral burner tips adapted to burn a combustion gas. The method is directed to such burner assemblies wherein substantially all of the combustion oxygen is provided by air directed into the air register. The method comprises the steps of replacing the oil-burning central tip with a gas-burning central tip and connecting the central tip to a source of combustion gas. The invention further provides a burner assembly having characteristics of the reconfigured burner assembly prepared from the method of the invention, namely a burner assembly having: an air register, a central burner tip and a plurality of peripheral burner tips, wherein the central burner tip is connected to a combustion gas conduit which has an eductor for drawing combustion oxygen into the central burner tip from a location outside the air register.
