When should the ignition module stop sparking?

The ignition module is designed to stop sparking when the flame is proven, which indicates that the burner has ignited successfully. This is an essential safety feature in gas appliances to prevent unnecessary fuel consumption and to avoid the risk of a gas build-up that could lead to an explosion. Once the flame is detected by a flame sensor or another means, the ignition module recognizes that the ignition process has been completed and ceases to generate sparks.

In practical terms, this means that the ignition module continuously monitors the presence of a flame. If there is no flame detected, the module will likely continue to spark for a predetermined time to attempt to ignite the gas. However, once the flame is confirmed, sparking is no longer needed, and stopping the spark also conserves energy and reduces wear on the ignition components.
