A metal body for the gas burner of an infrared radiant heater appliance, the body (1) being generally elongate in shape having an open front that receives a plate (25) for generating infrared radiation and itself being made up of two sheet metal parts (2, 3) that are cut out, stamped, folded, and assembled together. The parts comprise: a U-shaped back part (2) having an elongate main face (4) with a longitudinally elongate depression (5) shaped to form half of a tubular Venturi shape; and a dish-shaped front part (3) with an elongate bottom to the dish-shape that presents a longitudinally elongate depression (18) shaped to constitute half of a tubular Venturi, a portion of the bottom of the dish-shape situated beyond the outlet from the Venturi being cut out and folded towards the inside of the dish-shape so as to define an opening (23) through which the gas mixture passes into the dish-shape, said portion constituting a deflector (21) suitable for distributing the gas mixture inside the dish-shape.

Radiant burner body

An extra flat type gas burner assembly is provided, comprising an annular venturi (17), a tubular member (11) fast with the burner body (1) extending vertically thereunder to cover the injector (5) and position the latter coaxially at the intake (15) of the gas-air mixture in the burner body, whereas the injector (5) is supported freely by a structural element (18).
