Abstract
A gas burner 10 intended to point downwardly in use. The gas burner comprises a flame strip 24 in the form of a sheet material with a plurality of openings 38 therein to define ports for combustion gas. The outer side of the flame strip 24 provides a combustion surface in use. The gas burner also comprises a body member 22 with an inlet 18 thereinto for combustion gas. The body member 22 and flame strip 24 together define a combustion chamber 50, with a space between the flame strip 24 and an outer wall 32 of the body member. The body member 22 and/or flame strip 24 are profiled such that said space varies across the chamber 50 to provide a required flow of combustion gas across the chamber 50.
