Abstract
An assembly for controlling the flow of a gas to a gas burner. The assembly including a rotational regulating valve and an electromagnetic safety valve. The regulating valve is rotational between a first angular position corresponding to a closed position and a second angular position corresponding to an open position. The safety valve includes a valve member that translates axially between a first axial position corresponding to a closed position and a second axial position corresponding to an open position. An operating shaft is operably coupled to the rotational regulating valve and to the electromagnetic safety valve and is rotatable between angular positions corresponding to the closed and open positions of the rotational regulating valve and is axially translatable between axial positions corresponding to the closed and open positions of the valve member of electromagnetic safety valve, axial translation of the operating shaft is not permitted when the angular position of the operating shaft corresponds to an open position of the rotational regulating valve.
