Use Of The Burner; Servomotors - baltur BGN 200P Manual De Instrucciones

USE OF THE BURNER

The burner operates fully automati-
cally; therefore it is non necessary
to carry out any kind at adjustment
during its operation. 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 pro-
perly. 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 ope-
rating properly. If the burner stops
three or four times at a stretch, it
is necessary either to look for the
cause to 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 and
to close the fuel valve, to disconnect
the burner electrically.
