🔍 Key Concepts

• Combustion air flow and how long it takes for unburned fuel to clear from a furnace • Why you must be sure there is no residual fuel/flammable mixture before closing things up • Difference between removing heat vs removing combustible gases or vapors

💭 Think About

• Think about what is inside the furnace and gas passages immediately after you shut off the burners. What must be removed first for safety? • If you leave burner registers open for a few minutes, what does that mainly allow to pass through: heat, gases, or water vapor? • Which option is most closely related to preventing an explosive mixture from remaining in the furnace?

✅ Before You Answer

• Identify which choice relates to removing unburned fuel/combustible gases, not just temperature control • Ask whether simply "cooling" something is the primary safety reason for this procedure • Confirm which term is typically used in boiler operations for blowing fresh air through a furnace before or after firing for safety.
