Question 1 of 27070

Flame failure in an automatically fired auxiliary boiler can result from a/an __________.

🔍 Key Concepts

• automatic boiler ignition systems and how they maintain a stable flame • the difference between fuel supply problems and ignition/electrical problems • how a clogged fuel nozzle versus an improper spark/arc affects the flame after startup

💭 Think About

• Ask yourself which condition would most likely make the burner lose its flame after it has already been established, rather than just preventing ignition. • Consider which choices would reduce or interrupt the actual flow of fuel into the furnace, instead of only weakening the spark. • Think about how an automatic system responds: when the flame sensor no longer detects a stable flame, what underlying cause would trigger that situation among these options?

✅ Before You Answer

• Verify which option directly restricts fuel flow to the burner. • Check which options mainly affect the quality/position of the spark rather than the ongoing fuel supply. • Be sure you are focusing on flame failure during automatic operation, not just difficulty in getting the flame to light initially.
