The gas valve is a gas distribution device. When there is a need for more gas in the burner, a message is sent from the printed circuit board to the gas valve, which upon opening allows gas to pass through the valve in to the pilot assembly or the burner dependant on the model of the appliance installed ."
The spark generator is part of the pilot assembly and is responsible for generating a spark that ignites the pilot burner. It is controlled by the printed circuit board which is controlled via the control panel by the user .
The control knob sits on one of the spindles located on the front of the control panel and allows you to manually control certain aspects of the boilers functionality. Some boilers allow you to alter the temperature and some even allow you to change the current function. This means the user can have the boiler produce hot water without the central heating being on and vice versa .
