A gas burner has a burner base formed with inner and outer upwardly open annular base chambers each connected to a respective gas supply. An inner burner on the burner base has gas outlet orifices that create an inner flame ring. An annular outer burner on the burner base has inner gas outlet orifices on its inner annular periphery creating an intermediate flame ring and outer gas outlet orifices on its outer annular periphery creating an outer flame ring. This outer burner also has two coaxial and separate inner and outer annular gas chambers that are downwardly open toward the burner base. The outlet orifices of the intermediate flame ring open into the inner annular gas chamber while the gas outlet orifices of the outer flame ring open into the outer annular gas chamber.
