Abstract: A gas burner includes a burner pipe, in which gas is supplied and which is provided with a row of linearly arranged perforations that allow the gas through to a burner chamber, and an ignition mechanism to ignite the gas electrically. The burner pipe is provided on the inside with a gas distribution pipe in order to evenly distribute the gas supply over the entire row of perforations, and the burner chamber is surrounded by a premounted air chamber, which is connected to the burner chamber by means of air slots, whereby the air slots are oblique with respect to the longitudinal axis of the burner pipe at an angle between 10° and 80°, and whereby the air supply through the air slots is controlled by a device that blows in or draws in air through the premounted air chamber.
