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 interven-
tion 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.
