What are the three major functions of the spark ignition module?

The three major functions of the spark ignition module involve lighting the pilot, proving the flame, and stopping sparking when the burner is lit. This sequence is critical for the safe and efficient operation of gas appliances.

Lighting the pilot is the initial step where the spark ignition module generates a spark to ignite the gas coming from the pilot. Once the pilot is lit, the module proves the flame through sensors or circuits that confirm the presence of a flame, which is essential for ensuring that the gas is only flowing if there is a successful ignition. Finally, once the burner is lit, the module stops sparking, as continuous sparking can lead to safety hazards, including potential unburned gas accumulation.

These functions are vital for ensuring safety and reliability in gas appliance operation. Other options present functions that might be relevant in broader heating or cooking contexts but do not accurately represent the specific core functions of the spark ignition module itself.
