  • Patent number: 4437830
    Abstract: The movable elements of two normally closed valves are actuated by a thermal element responsive to ignition at a pilot burner supplied fuel through one of the valves. The two valve elements form a mechanical train from the thermal element which simultaneously unseats the second valve controlling fuel to the main burner and releases a manually operable mechanism with which the pilot burner valve is initially unseated for ignition.
