(54) Mixer tube assembly for fuel gas burner


(57) A fuel/air mixture tube assembly (10) for interconnecting a range top burner with a fuel gas manifold. The tube is preferably formed by stamping half shells (12,14) from thin sheet metal and joining the half shells to form a tube having an inlet (16) for connection to the manifold and an outlet (20) for connection to the burner inlet. An inlet flap or door (54) is integrally stamped in the half shells adjacent the inlet end. After assembly the flap or door may be mechanically deformed to vary the air inlet opening.
