Abstract
An ignition spark emitter for a fuel operated heating device has two electrodes which are addressed by a transformer and deliver ignition sparks. The ignition electrodes are secured at a housing of the ignition spark emitter which also contains the transformer and the power supply unit of the ignition spark emitter. A plug connector, which preferably, is disposed in the form of a plug-in unit is provided at the housing of the ignition spark emitter, and not only establishes the electrical connection of the ignition spark emitter, but also serves for its mounting, preferably, in proximity of the nozzle assembly of the burner. One of the ignition electrodes, in connection with a ground circuit, can be utilized for ionization flame monitoring via the combustion tube of the heating device, whereby the ionization flame monitor appropriatelylame monitoring via the combustion tube of the heating device, whereby the ionization flame monitor appropriately is operated in a time multiplex manner. An evaluation device, whose output signal is transmitted for ionization flame monitoring via the plug connector for further processing, is also disposed in the emitter housing.
