Abstract (en)
Method for operating a gas burner appliance (10), the gas burner appliance (10) comprising: a combustion chamber (11), a mixing device (23), a fan (14), a gas safety valve unit (19) assigned to the gas duct (16) having a first gas safety valve (19a) and a second gas safety valve (19b) positioned downstream of the first gas safety valve (19a), a gas flow modulator (18) assigned to the gas duct (16), and an electrical or electronic absolute pressure sensor (21) assigned to the gas duct (16) positioned downstream of the first gas safety valve (19a). The gas burner appliance (10) is operated to compensate for a fluctuating gas inlet pressure of the gas burner appliance by executing the following steps: Measure a first absolute pressure by the absolute pressure sensor (21) when at least the first gas safety valve (19a) of the gas safety valve unit (19) is closed. Measure a second absolute pressure by the absolute pressure sensor (21) when the gas safety valve unit (19) is opened. Determine a pressure difference between the first absolute pressure or a pressure depending on the first absolute pressure and the second absolute pressure or a pressure depending on the second absolute pressure. Operate the gas flow modulator (18) dependent from said pressure difference.
