🔍 Key Concepts

• automatically fired auxiliary boiler safety sequence and flame safeguard system • difference between ignition circuit problems and fuel delivery problems • how a flame detector would respond to loss of ignition vs loss of fuel

💭 Think About

• In an automatic boiler, what has to happen first to establish a flame: proper spark or proper fuel spray? Which failure would more directly remove the flame once already established? • Which of the listed faults would most likely interrupt the fuel being burned rather than just the starting spark? • If the flame monitoring device suddenly no longer ‘sees’ a flame, which type of problem—electrical ignition side or fuel flow side—would actually stop combustion after it has been running?

✅ Before You Answer

• Identify which choices affect initial ignition only versus those that affect continuous combustion. • Consider which component, if it fails while the boiler is already firing normally, would actually cause the flame to go out rather than just prevent a restart. • Double-check how a clogged fuel nozzle and a faulty signal in the trial-for-ignition circuit each affect the burner operation over time.
