Abstract

The invention relates to a gas forced air burner having modulatable burner power for a gas heating appliance, having an air path (2) for feeding combustion air supported by a fan, a gas path (6) for feeding a fuel gas, a gas valve (7) for regulating the amount of the fuel gas, a burner surface and a distribution chamber (9) disposed upstream of the burner surface (10), into which the combustion air and the fuel gas open, characterized in that the burner surface and the distribution chamber are divided into at least two regions, and that the gas path divides into at least two partial gas paths (6 -1, 6 -2) at a branch downstream of the gas valve, each partial path being connected to an associated region of the distribution chamber. The method according to the invention for operating a gas forced air burner is characterized in that a fuel gas flows directly into a first region of a burner surface when operating in a first burner power range, mixes in said first region with combustion air into a fuel gas-air mixture, and the combustion is then begun. When operating in a second burner power range, the fuel gas flows through an air path guiding air to a mixture forming section, from where said gas flows further as fuel gas-air mixture to a second region of the burner area, and then is fed to the combustion.
