Zusammenfassung:The invention pertains to a method for operating a surface stabilized fully premixed gas premix burner. The burner is adapted to modulate between a minimum load and a full load, the ratio of the full load over the minimum load being at least 4. The method comprises the step of supplying a premix of combustible gas and air to the burner at an air to combustible gas ratio, the combustible gas supplied to the burner comprises at least 20% by volume of hydrogen, In the method, the air to combustible gas ratio of the premix which is supplied to the burner when the burner is operated at minimum load is set by a mechanism to be in relative terms at least 20% higher than the air to combustible gas ratio of the premix which is supplied to the burner when the burner is operated at full load.
