🔍 Key Concepts

• Boiler furnace explosions and how they occur during light-off • Purpose of a furnace purge before and after failed ignition attempts • Why unburned fuel or vapors in the furnace are dangerous on the next light-off attempt

💭 Think About

• What happens to the fuel that entered the furnace during the failed light-off attempt? Where is it now? • Before trying to light the boiler again, what must you do to make the furnace atmosphere safer for ignition? • Which choice specifically removes accumulated fuel vapors rather than just waiting or trying again?

✅ Before You Answer

• Verify which option involves securing (shutting off) the fuel supply after a failed light-off. • Identify which option requires a forced draft fan purge of the furnace before re-ignition. • Eliminate any choices that allow repeated light-off attempts without addressing trapped fuel vapors in the furnace.

If an attempted light off of an idle boiler fails, what should be done?

The fuel should be secured to the boiler and the boiler allowed to remain idle for a few minutes before another light-off attempt is made.

Another light-off attempt (just one) can be undertaken before any additional precautions need to be observed.

Another light-off attempt (with no limit) can be undertaken before any additional precautions need to be observed.

The fuel should be secured to the boiler and the furnace purged of combustible vapors with the forced draft fan before another light off attempt is made.
