<p>The present invention provides an assembly (1) for controlling supply of gaseous fuel to a gas burner. The assembly (1) includes a manifold (2) of tubular construction (3) defining a passage for supply of gas therethrough. The assembly also includes valve means (4) having one or more orifice (14, 15, 16) for regulating or controlling the volume rate of gas flow (G) through the valve means to a burner. The valve means (4) is combined with the manifold (2) such that the at least one flow regulating orifice (14, 16, 17) is located inside the manifold tube (3). The invention also provides a valve means (4) in the form of a gas cock and a manifold (2) suitable for producing the above assembly (1).</p> |
