Explanation:
In an intermittent pilot system, the pilot is lit each time there is a call for heat by the thermostat. This system ignites the pilot flame only when heat is needed, and it is extinguished when the heating cycle is complete. The pilot flame is typically smaller in intermittent pilot systems compared to other systems, as it only serves the purpose of igniting the main burner.
