Pellet burner GP 45 IV 37
To initiate fuel final combustion the button “S” must be pressed, which is located bellow
[YES]. To cancel the final combustion initiation or to return to the previous menu press the
button “ESC”, located bellow [NO].
In case the pellet burner from series “GP” should be stopped from operation, an
entire cleaning of the combustion chamber from the ash deposits has to be
performed, as well as cleaning of the appliance heat exchanging surfaces, to
which it is mounted, because the ash has corrosive influence over the steel
surfaces, which reduces the life of the appliance. A prophylaxis of the burner by
specialized servicing company has to be performed also. Observance of these
procedures provide longer and reliable operation life of the burner.
If an operation stop signal is received by the burner the fuel feeding stops, but its
fresh air fan continues operation. Therefore after receiving a stop signal the
burner continues to burn and to generate heat energy, which makes it inert,
respectively the entire heating system becomes inert. This feature is important if
the radiators are equipped with thermostatic regulators (or other control
components), which close the circulations water flow. As a consequence of this
process the generated by the burner energy might not be “unloaded” and could
lead to overheating of the appliance. Therefore in case a pellet burner from
series “GP” is used and the heating system radiators are equipped with such
thermostatic regulators (heads) it is necessary not to close them completely,
and/or at least one of the radiators should not be equipped with such regulator, in
order to ensure constant energy release in all operation modes.

SWITCHING OFF THE PELLET BURNER FROM SERIES “GP IV” BY EXTERNAL
MODULE, CONTROLLING ITS OPERATION.
The burner switch off is achieved by interrupting its operation signal, which is submitted to
the burner by external module or by performing the procedure for stopping its operation, as
described in the previous chapter. When the burner transits from burning mode to pause
mode or to “shut down” mode, then the control module performs the so called process of
“controlled stopping”, during which the fresh air fan continues its operation and the
controllers monitors the emergency signals. After the burner cools down its power supply has
to be cut off. It is also recommended to clean the system burner-appliance from the ash
deposits.
6.5.1.
BURNER EMERGENCY SHUT DOWN.
During operation of the burner emergency mode situations are possible to occur. Such
situations are read by the control module and it automatically performs prevention
procedures. The burner controller transits to emergency mode by indicating an error code on
the display. The alarm codes and other messages are presented in Table 7.2.
If an emergency situation occurs the failure/alarm code, shown on the display, must be
checked and the relevant corrective measures should be taken, in order to remove the failure
cause. After that the burner should be restarted from its power supply. Before restarting the
burner it is necessary to clean its fire-grate from the ash deposits and fuel remaining;
In case of overheating (emergency situation) of the appliance to which the burner
is mounted, the emergency thermostat activates, which is MANDATORY
equipment and is not part of the burner’s delivery kit. The emergency cause must
be diagnosed and removed. The emergency thermostat must be switched back
on manually, so the burner can receive power supply signal.
