These parts can also be referred to as a heater coils or Piezos and are designed to ignite the gas in the combustion chamber within the Worcester Bosch boiler. They are normally attached to the spark electrode via a lead and also to the printed circuit board. The generator generates a high voltage that arcs across the spark electrode causing a hot spark to take place, this spark ignites the gas being emitted from the main burner.
