monitored, in case of emergency appropriate actions will be taken. After the
burner has been cooled down (to ambient temperature), it should be switched off
by turning off the main power supply of the heat consumer unit. It is
recommended to clean the deposited ash thoroughly both of the burner as well
as heat consumer surfaces.
• Emergency burner stop
In operating process of the burner emergency situations could arise and the
unit will go into alarm/failure mode. Such situations are detected by the
process control board and it will go into automatic protective mode in order
to be protected as well as the heat consumer unit. These modes are operated
by appropriate preventive measures, automatically taken by the control
board of the main module and the alarm mode is indicated by the LEDs of
the control board and eventually will identify it. Please check the status of
the LEDs and refer this manual before taking any actions. After the cause
of the alarm situation is clarified, take adequate actions for bringing back
the burner into normal operating conditions and restart it by switching off
the power supply OFF the main module and back into ON.
ATTENTION :
• in case of emergency situation – heat consumer overheating, the
emergency thermostat (which is not part of the burner’s equipment and is
installed on the control module of the unit) is activated. In this case the
system (burner-heat consumer) should be cooled down and the reason for
such emergency situation should be investigated and preventive measures
should be performed. The emergency thermostat should be manually reset
by unscrewing its preventive cap and its stem should be pressed until the
thermostat switches back on (a “click” sound is heard in this process),
then screw back its cap. After the system (burner-heat consumer) boiler is
checked and the cause for overheating is determined and repaired, restart
the burner by turning off its power supply and then back on in order to run
the burner in normal mode;
• in case of alarm mode – fuel delivery pipe overheating, the alarm thermo-
probe of the burner’s main module is activated and the control board
switches into alarm mode. This thermo-probe senses the temperature on
the surface of fuel pipe and prevents so called “back fire” process. After
the unit is cooled down and the reason for such kind of emergency
situation are clarified and special preventive measures have been taken,
then the burner should be restarted into nominal operating mode. This is
done by manual switch OFF and back ON of the power supply of the
burner. In some situations this thermo-probe could be thermally damaged
and will need renewal, in such situation please refer to service assistance;
