A gas burner (30) includes an outer cylindrical wall (16) defining an internal cavity (20) for receiving a gas and air mixture and the outer cylindrical wall (16) includes a plurality of apertures (26) to allow a gas and air mixture to pass from the internal cavity (20) to an outer surface (16a) of the outer cylindrical wall (16) for combustion. A securing member (32) is attached to one end (33) of the outer cylindrical wall (16) and includes a circumferential inner rim (36) defining a circular opening (38). An inner cylindrical wall (18) is located inside the internal cavity (20) and defines at one end (50) thereof a circular flange (48), the circular flange (48) extending axially through the circular opening (38) and in a radially outwards direction to thereby secure the inner cylindrical wall (18) to the securing member (32). At least part of the circumferential inner rim (36) of the securing member (32) extends in a radially outwards direction and includes a slot (40). |
