<p>A tube assembly for a gas range includes a small aluminum manifold block (12), valve assemblies (22, 24, 26, 28) adapted to regulate flow of gas from the manifold block to the burners, and burner orifices (40) adapted to control flow of gas to the burners. Aluminum valve supply tubes (14, 16, 18, 20) each have a first end stacked to an associated outlet of the manifold block and a second end connected to an inlet of an associated one of the valve assemblies. Aluminum burner tubes (32, 34, 36, 38) each have a first end connected to an outlet of an associated one of the valve assemblies and a second end connected to an associated one of the burner orifices. Two or more small manifold blocks can be interconnected by aluminum manifold supply tubes (144). The manifold supply tube can be easily bent to position the manifold blocks in any desirable position. An igniter assembly includes a pin (132) extending from a stem of the valve assembly and a contactless position sensor (88). The sensor is activated by the pin in the full-on position which in turn activates a spark module (89) at the burner to ignite the burner.</p> |
