🔍 Key Concepts

• Flame failure switch purpose in an automatic boiler safety system • What condition the switch is designed to detect: presence or loss of actual flame • Difference between stopping ignition and stopping fuel flow to a burner that is firing

💭 Think About

• Ask: How does the boiler know there is truly no flame in the furnace, not just no ignition spark? • Consider which action would simulate a real operating hazard that the flame failure device is intended to protect against. • Think about what must happen first in a safe shutdown sequence when a flame is lost but fuel is still being supplied.

✅ Before You Answer

• Verify which option actually removes or interrupts fuel to a burner that is currently firing. • Check which choice most realistically imitates a flame-out condition during normal operation. • Eliminate any options that only affect ignition voltage or firing rate without proving whether the device senses loss of flame.
