What is an intermittent pilot system designed to do?

• A. Ignite the main burner continuously
• B. Improve heating by utilizing a fan
• C. Ignite the main burner only when there is a demand for heat
• D. Regulate gas flow in low-pressure systems

Answer: (C)

An intermittent pilot system is specifically designed to ignite the main burner only when there is a demand for heat. This means that the pilot light does not stay on continuously; rather, it only activates when the temperature drops below a set point or when the thermostat calls for heat. This system enhances energy efficiency by reducing gas usage since the pilot light isn't on all the time, which ultimately leads to cost savings and reduced emissions. In contrast to other methods, such as having a continuously lit pilot light, the intermittent pilot system allows for greater control of the heating system based on actual heating needs. It is also designed to safely and automatically ignite the main burner without requiring ongoing manual intervention. Therefore, option C effectively captures the primary function and advantage of an intermittent pilot system in heating applications.
