🔍 Key Concepts

• Panting in boilers – what it means physically (pressure pulsations / surging in the furnace or steam space) • Conditions that cause rapid pressure fluctuations rather than a complete shutdown • Normal boiler safety responses to low water level, flame failure, or scanner faults

💭 Think About

• Think about which option would make the furnace pressure and/or steam pressure surge up and down, rather than simply stopping the burner or tripping the boiler. • Ask yourself: which condition would still allow the burner to fire, but in an unstable, oscillating way? • Consider how the boiler’s automatic safety devices react to low water level, complete flame failure, or a bad flame scanner—do these usually cause pulsing or an immediate trip?

✅ Before You Answer

• Identify which choice would most likely cause unstable combustion rather than an automatic shutdown. • Eliminate any options that normally cause a safety trip (low water, proven flame failure, loss of flame signal). • Focus on the condition that affects air–fuel mixture stability and furnace pressure, not on the electronic detection devices.
