In a direct ignition system, what does the igniter actually light?

• A. The pilot light only
• B. Both the burner and pilot light
• C. The main burner only
• D. The gas supply

Answer: (C)

In a direct ignition system, the igniter is designed to ignite the main burner directly. When activated, the igniter generates a sufficient amount of heat to ignite the gas being supplied to the main burner, initiating the combustion process. This system allows for a more efficient and immediate start-up compared to traditional pilot light systems, which require an ongoing flame to ignite the gas. In this context, while some systems may have features that involve pilot lights, the primary function of a direct ignition system is to bypass the pilot light entirely, focusing solely on igniting the main burner. This enhances operational efficiency and improves safety, as there is no need for a continuously burning pilot flame.
