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)(A)
pushbutton lights up, it indicates that the burner
is in lock-out.
To reset, press the pushbutton, no sooner than
