🔍 Key Concepts

• Automatic safety shutoff functions on oil-fired boiler burners • Boiler flame failure and safety trip conditions • Purpose of burner valves in preventing fuel flow during unsafe conditions

💭 Think About

• Ask yourself: in which situation would continuing to supply oil to the burner be MOST dangerous? • Which option describes a condition that should STOP fuel flow, not start or continue it? • Think about the sequence of burner operation: purge, trial for ignition, flame proven, normal firing. At what point should the automatic system be ready to shut the valve immediately?

✅ Before You Answer

• Identify which choices describe a normal condition versus a fault or emergency condition. • Verify which event is directly tied to a boiler safety trip or unsafe state. • Confirm that the correct choice would cause the fuel supply to stop rather than continue.
