Q

Burner ignition failure in an automatically fired auxiliary boiler would be caused by __________.

🔍 Key Concepts

• Automatic boiler ignition sequence (pre-purge, pilot, main flame, safety interlocks) • How fuel oil solenoid valves affect fuel flow to the burner • What happens if a control relay or interlock is out of position or not made up

💭 Think About

• Which option would physically prevent fuel from reaching the burner at the moment of ignition in an automatic system? • Which choices are more about normal operating conditions (efficiency, temperature control) rather than a hard ignition failure? • Think about the role of electrical components (solenoids, relays) in the automatic start sequence—what happens if one of them fails or is misaligned?

✅ Before You Answer

• Identify which components are in the fuel supply path right before ignition (valves, solenoids, relays). • Decide which option would cause a no-fuel or no-start condition rather than just poor combustion. • Confirm which choice is not directly involved in the burner ignition circuit (e.g., hotwell or excess air settings).
