  • the positioning accuracy of the spark plug is improved, resulting in a robust, reliable ignition.
  • the positioning accuracy of the thermocouple is also improved, thereby reliably ensuring flame detection.
  • the assembly of the burner due to the fact that except the mounting device in the form of a spring plate, if necessary, a fixing element in the form of a clip is required.
  • the design costs for different designs are low.
