bring the burner to a standstill. When the temperature (pressure, if
steam boiler) drops below the intervention limit of the "shut down"
N
device, the burner will start up again as previously described.
During normal operations, the thermostat (or pressure switch) of the

2nd stage is aware of load variations in the boiler and automatically

requests the servomotor regulating delivery (fuel/air) to make an
adjustment in the fuel delivery and in the relative combustion air.

With this manoeuvre, the delivery regulating system (fuel/air)
reaches a position of equilibrium which corresponds to a fuel de-
