- relay means responsive to the application of power thereto, said relay means controlling the operation of the valve;
- means for detecting the presence of a flame at each burner within the plurality of burners; and
- means for controlling the application of power to said relay means, said controlling means comprising timing means and a plurality of switching means, each switching means within said plurality of switching means being associated with a burner within said plurality of burners, said timing means cooperating with said each switching means within said plurality of switching means preventing the application of sufficient power to said relay means to actuate said relay means and the valve for a first pre-determined period of time and allowing sufficient power to be applied to said relay means actuating said relay means and the valve for a second pre-determined period of time, said timing means cooperating with said each switching means within said plurality of switching means preventing the continued application of sufficient power to said relay means after the expiration of said second pre-determined period of time unless said detecting means determines that a flame is present at each burner within said plurality of burners.
