is recommended to install a heat accumulating tank parallel to the
circuits of the heating system in order to achieve a buffer effect and to
decrease any variations of the consumption of heat energy by the heating

Turning OFF the automatic pellet burner of series “GP”
The pellet burner is turned off by changing the “START” signal status into
OFF, supplied by the control module of the heat consumer unit. During the
working process in OFF state, the control module of the burner performs so
called “controlled turning off procedure” in which the air fan is working (and
the burner is cooled down) and operating parameters are simultaneously
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 energy 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
obligatory
– it should be 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-
