Abstract (en)
The invention relates to method for starting up a gas burning appliance (1). The method comprises an ignition sequence comprising:- activating an igniter (6) for a predetermined ignition time,- opening a gas supply (3) for a predetermined safety time to supply combustible gas to a burning chamber (2), the combustible gas being a hydrogen comprising gas,- detecting the presence of a flame by means of a flame detector (5),- closing the gas supply (3) if no flame has been detected at the end of the predetermined safety time. The combustible gas comprises more than 20 mol% of hydrogen and activation of the igniter commences at a predetermined pre-ignition time interval before opening the gas supply (3).
