Which ignition method uses a spark to ignite the pilot?

• A. Intermittent pilot
• B. Standing pilot
• C. Electronic ignition
• D. Hot surface ignition

Answer: (A)

Intermittent pilot ignition uses a spark to ignite the pilot flame. When heat is needed, the control creates a brief electrical spark at the igniter to light the pilot gas. Once the pilot flame is established, it remains enough to light the main burner when called for, and the spark stops until the next demand for heat. This is different from a standing pilot, which keeps a small flame continuously lit; electronic ignition typically uses a spark to ignite the main burner rather than the pilot; and hot surface ignition relies on a heated element to ignite the gas, not a spark.
