This patent describes a heating appliance employing a surface combustion or radiant burner that burns a combustible gas comprised of a mixture of gaseous fuel and combustion air and that emits radiation while burning the combustible gas, having means for supplying the gaseous fuel to the radiant burner at one or more flow rates and having means for supplying the combustion air to the radiant burner at a variable flow rate, a method of setting the proportion of the gaseous fuel to the combustion air in the combustible gas to a desired proportion. It comprises determining a reference intensity, the reference intensity being the intensity of radiation emitted by the radiant burner when the radiant burner is burning a reference combustible gas; setting the gaseous fuel supply means at a given flow rate; sensing the intensity of radiation emitted by the radiant burner while the radiant burner is burning the combustible gas; and controlling the combustion air supply means so as to reach and maintain a flow of combustion air that will produce a resultant combustible gas having such a proportion of gaseous fuel to combustion air that, when the radiant burner burns the resultant combustible gas.
