Answer :
Final answer:
In an Intermittent Pilot Ignition system, the pilot is not lit when the furnace is off, saving energy by igniting the pilot only on a heating cycle.
Explanation:
When dealing with an Intermittent Pilot Ignition system in furnaces, the pilot light status is dependent on the furnace operation. With Intermittent Pilot systems, the pilot is not lit when the furnace is off. This is in contrast to a standing pilot ignition system, where the pilot light remains lit at all times. The Intermittent Pilot system is designed to ignite the pilot light only when the furnace is about to begin a heating cycle, thus saving energy when the furnace is not in use.
