🔍 Key Concepts

• Boiler furnace purging before lighting off • Relationship between fuel/air mixture and ignition in enclosed spaces • Difference between flash point and normal operating fuel temperature

💭 Think About

• Which condition would leave unburned fuel or vapors in the furnace so they could suddenly ignite? • For each option, ask: does this situation make combustion more controlled and stable, or more likely to create an explosive mixture? • How does proper light-off procedure prevent dangerous accumulations of fuel or combustible vapors?

✅ Before You Answer

• Identify which option directly involves start-up/light-off procedures rather than steady-state operation • Check which condition would most likely create a flammable mixture in a confined space rather than just poor efficiency • Recall that flash point is the temperature where vapors can ignite if an ignition source is present, not where normal operation is set
