When the burner motor is started a pre-
ventilation period of 30 seconds begins
during which the ignition transformer is also
activated. When the pre-ventilation and
pre-ignition phase has been completed, the
selected fuel valve opens and the fuel starts
to flow with formation of the flame. If the
flame does not appear 3 seconds after ope-
ning the fuel valve, the burner locks. If the
flame accidentally goes out during normal
operation, the burner locks completely. The
burner is turned on again by pressing the
lock reset button (7).
