In an intermittent pilot ignition system, what does the igniter do?

In an intermittent pilot ignition system, the igniter plays a crucial role by specifically igniting the pilot flame. This system is designed to enhance safety and efficiency in gas appliances by using a pilot light that only activates when needed.

When the appliance calls for heat, the igniter generates a spark or flame to light the pilot, which then enables the main burner to operate once the pilot is confirmed to be lit. This process occurs intermittently; the igniter is not continuously generating heat, but rather is activated periodically to ignite the pilot when required.

This approach minimizes gas consumption and reduces the risk of gas leaks, as the pilot flame only burns when the appliance is in operation. Understanding this mechanism is essential for safety and proper functioning when working with gas appliances.
