Abstract
A method for the failsafe and lean ignition of a fuel gas-air mixture on a gas burner (), which is mixed in a mixing device () arranged upstream of the gas burner (). A control valve () along the fuel gas flow path has an actuator () and a throttle element (), moved by the actuator (), for the closed-loop control of a flow rate of the fuel gas flowing into the mixing device (). A test is performed to determine whether the throttle element () is in the throttle reference position when the actuator () is in the actuator reference position. The throttle element () is moved in a flow rate-increasing manner starting at a start time (tD). The flow rate-increasing movement of the throttle element () is stopped as soon as at least one of multiple predetermined termination conditions occurs.
