ABSTRACT:
An apparatus which is operated for opening and maintaining the flow of a gaseous fuel to a burner only after the fuel is ignited in a gas appliance, such as a gas room heater. More specifically, the apparatus has a lever with three operating positions, a starting position, an intermediate position, and a final position. From the starting position, which is an inoperative mode, the lever is capable of being moved in a first direction to an intermediate position wherein actuation of a valve to the fuel source occurs allowing fuel to enter into the burner, and a final position wherein ignition of the fuel in the burner is actuated. A continuous force urging the lever in a second or opposite direction is included as well as a locking mechanism for holding the lever in the intermediate position, which locking mechanism is activated only after the lever has first been moved to the final position, hence avoiding the condition where the burner is continuing to be supplied with fuel without ignition of the fuel.
