A combustion assembly includes a single stage gas valve, a burner member having a flame end, a spark generating member, a name sensing member, and a controller. The spark generating member generates a spark in response to a spark signal and is positioned adjacent to the flame end of the burner membe r. The flame sensing member senses the presence of a flame and is also positioned adjacent to the flame end. The controller provides a valve open signal to the valve t o control a flow of gas to the burner member, provides a spark signal to the spark generating member to generate a spark that ignites the flow of gas, receives a flame sense signal from the flame sensing member related to the state of the flame, and provide s a valve closed signal to stop the flow of gas when the flame sense signal indicates no flame is present.
