Two solenoid control valves are required on large automatic auxiliary boilers and will simultaneously shut off the fuel in the event of __________.

🔍 Key Concepts

• Automatic boiler safety devices and what conditions are considered dangerous enough to require immediate fuel shutoff • The purpose of low-water cutout and flame safeguard systems on large auxiliary boilers • Which of the listed conditions is most directly linked to risk of overheating and boiler damage

💭 Think About

• Ask yourself: which condition would most quickly create a serious hazard inside the boiler if fuel kept burning? • Think about which protection is ALWAYS required on large automatic boilers to prevent the boiler from firing when it is unsafe. • Compare each choice: is this condition normally handled by shutting down fuel, by electrical protection, or by pressure‑control devices?

✅ Before You Answer

• Verify which condition is specifically tied to a low-water cutoff device that stops fuel flow to protect the boiler • Check which listed protections are usually handled by separate electrical safety devices, not necessarily the fuel shutoff valves • Confirm from your boiler-systems notes which single condition absolutely must trip the redundant solenoid fuel shutoff valves on large automatic boilers
