Start-up, calibration and operation of the burner
6.11 Burner flame goes out during operation
If the flame accidentally goes out during operation, the control
box carries out a recycle (i.e. it repeats the start-up phase once,
and makes a further ignition attempt).
If the flame is still absent, the control box goes into lockout.

The burner can be stopped by:

intervening on the disconnecting switch of the electrical sup-
ply line, located on the boiler panel;
