MAINTENANCE
The burner does not require special maintenance, but it is good practice to check periodically that the gas filter is
clean and that the ignition electrode is efficient. It is also necessary to verify that the ignition electrode’s spark is
produced between the same electrode and the disk. The combustion head may need cleaning. During re-assembly,
special attention must be paid to centring exactly the electrodes (ignition and flame detection) in order to avoid them
going to earth or short-circuiting which would result in the “shut down” of the burner.
USE OF THE BURNER
The burner operates fully automatically, therefore it is non necessary to carry out any kind at adjustment during its
operating.
The “block” position is a safety position reached by the burner automatically when some of the components of the
burners or the plant do not work properly.
It is necessary to check then whether the cause to the problem is a dangerous one before unblocking the burner.
The causes to the block may be temporary, for example when air in inside the pipes.
When it is unblocked, the burner starts operating properly.
If the burner stops three or four times at a stretch, it is necessary either to loock for the problem and solve it or ask
for the intervention of the after sales service.The burner can remain in the “block” position without any limit in time.
In emergency cases it is advisable to close the fuel valve, and to disconnect the burner electrically.
