Method for determining in a heating appliance whether ignition of the mixture of fluid fuel and air has taken place, comprising the following steps of:
- applying an electrical ignition signal to a measuring circuit;
- filtering a combustion signal from the ignition signal;
- comparing the detected combustion signal to a predetermined pattern;
- and
- establishing that the anticipated combustion signal took place during a predetermined period of time.
Device for determining in a heating appliance whether ignition of the mixture of fluid fuel and air has taken place, comprising:
- measuring means to which an electrical ignition signal has been applied;
- filter means for filtering a combustion signal from the ignition signal;
- comparing means for comparing the filtered combustion signal to a predetermined pattern;
- and
- determining means for establishing whether the combustion signal occurred during a predetermined period of time.
Device for combusting a mixture of fluid fuel and air, comprising:
- a gas valve control block unit for supplying gas;
- a fan connected to a gas valve control block unit for drawing in air;
- a burner disposed close to a heat exchanger;
- and
- discharge means for discharging the combusted mixture, wherein an ignition pin is arranged close to the heat exchanger and wherein the heat exchanger is provided with a protruding counter-electrode.
