26 Valve assembly with pressure regulator on nozzle return
27 Servomotor, provides adjustment of fuel delivery regulator
and of air gate valve.
When the burner is not operating the air gate valve is fully
closed in order to reduce to a minimum heat dispersion from
the boiler due to the flue draught which draws air from the
fan suction inlet.
Two types of burner failure may occur:
Control box lock-out: if the control box 23) (Fig. 1) pushbutton
lights up, it indicates that the burner is in lock-out. To reset, press
the pushbutton, no sooner than 10 s after the lock-out.
Motor trip: release by pressing the pushbutton on thermal cut-out
19)(Fig. 1).
