    摘要: In an air-gas mixture burning appliance (100) that comprises a burning unit (120), a flame detector (150) an air-gas mixing unit (110), a gas valve (194), and a controller (140), the controller (!40) being adapted for determining an earliest flame appearance time for an ignition phase of the burning unit (120) by selecting from at least two different durations of time, wherein the controller (140) determines the earliest flame appearance time as an anticipated minimum duration of time that elapses between an opening of the gas valve (194) and the flame detector (150) sensing the presence of a flame (122) in the burning unit (120).
