If the flame does not appear within 3 seconds after the gas valves
have opened, the control box goes into the lock-out condition (the
burner shuts down completely and the warning light turns on).
To "reset" the control box operation, press the reset button.
CAUTION / WARNING
The electronic cam controls the burner, activating the com-
bustion air, gas servomotor and the fan motor, if the inverter
is fitted, according to a curve that has ten points set (see
curve regulation table).
