🔍 Key Concepts

• Auxiliary boiler automatic combustion controls and what happens during a normal/safety shutdown • Purpose of a post-purge or furnace purge before lighting a burner • What could happen if unburned fuel or combustible vapors remain in the furnace and the burner is refired immediately

💭 Think About

• Think about what is left inside the furnace at the moment of shutdown and what needs to be removed before lighting off again. • Which option describes a safety action that protects against furnace explosions or fires, rather than a routine control or level adjustment? • Does the system need time for mechanical equipment to restart, or for the boiler space itself to be made safe for re-ignition?

✅ Before You Answer

• Identify which choice is directly related to removing unburned fuel or vapors from the furnace or combustion space. • Ask: which option is a standard safety step in boiler light-off procedures found in boiler operating manuals? • Eliminate options that deal only with electrical buildup or normal control functions that are not directly tied to preventing furnace explosions.
