The firing of a burner with the fuel controls in a low fire position to provide a minimum of incoming fuel from the main fuel valve(s) to give a smooth start and to provide a safe operating condition during lightoff. In a system with guaranteed low fire start, interlocks are used to prevent startup if the burner is not in the low fire start position.  1, record 6, English, - low%20fire%20start

Low-high-low prepurge-a prepurge period during which the air damper is driven open for the purge period and then back to low fire position for the burner lightoff. This is called low-high-low proven prepurge if suitable interlocks indicate that the damper actually reached the open position during prepurge, and then closed again before ignition trials.  1, record 7, English, - low%2Dhigh%2Dlow%20proven%20prepurge

A condition of normal lightoff but with rpm remaining at some low value rather than increasing to the normal starting rpm. This is often the result of insufficient power to the starter, or the starter cutting off before the engine starts self-accelerating. In this case, the engine should be shut down.  2, record 9, English, - false%20start
