🔍 Key Concepts

• Automatic boiler safety interlocks in the burner circuit • Difference between pressure limit switch, low-water cutoff, and alarms • Purpose of the burner control circuit in maintaining safe steam pressure

💭 Think About

• Ask what must happen to the burner when the boiler reaches its maximum safe steam pressure—should it keep firing or change state? • Consider whether a pressure limit switch is meant to detect flame, water level, or system pressure. • Think about which device specifically protects against low water level versus high steam pressure.

✅ Before You Answer

• Identify the primary job of a steam pressure limit switch on an automatic boiler (control at high pressure, not low water or flame presence). • Separate in your mind the function of a low-water cutoff device from a pressure limit switch. • Verify which choice describes an action that directly controls burner operation when cutoff pressure (maximum set pressure) is reached.
