Pellet burner GP xx sc 17
The sensitive component of the circulations water temperature sensor has to be mounted in
a sleeve for measuring of the outlet water temperature of the hot water boiler or has to be
screwed in a threaded orifice (depending on the sensor type).
6.2.3. SWITCHING ON THE PELLET BURNER FROM SERIES „GP XX SC”.
The burner switching ON has to be performed through the power supply of the appliance, to
which it is mounted. If the burner has been in operational mode (or in “hot reserve”) but the
power supply has been interrupted, then when the power supply restores the burner will
continue its operation automatically.
In case the appliance to which the burner is mounted is not properly sealed and
the burner is operating, smoking of flue gasses through the unsealed sections is
possible to occur, as well as through the fuel feeding flexible pipe. It is
recommended to seal these sections and to adjust the burner’s heating output in
order to avoid such smoking. The same effect might be monitored during the
transition seasons – autumn and spring, when the natural chimney draught is
decreased due to higher ambient temperatures.
During the burner’s ignition mode the heating elements activate, which are
positioned under the combustion chamber’s fire-grate. This zone is heated to
high temperatures and could be dangerous in case it is touched – manipulations
in the burner’s combustion chamber zone should not be performed. If necessary
to stir (spread) or remove the fuel then proper tools and personal protection
equipment must be used.
When initiating the burner to operation for the first time the auger (fuel feeding)
device must be filled with pellets – this is continues process requiring time.
Therefore the auger must be connected to external power supply, through its
standard plug and to wait until the fuel starts to drop from its top orifice. After that
it must be connected to the power supply socket of the burner’s main module.
The burner’s main module constantly checks if the feeding auger is connected to
its socket and if this condition is not fulfilled the system will transit to emergency
mode, until the auger’s power supply cable is connected properly. After that it is
necessary to restart the burner’s main module in order to transit to normal
operational mode.
If the power supply cable of the transport auger has been disconnected from the
burner’s main module socket (this situation is treated by the controller as an
emergency mode – i.e. there is no motor connected to the socket) and the burner
has been operating at that time, then an emergency mode activates and the
burner operation stops. To reset the alarm it is necessary to connect the auger’s
plug back to the burner’s main module and to switch the burner’s power supply
button to position OFF and then back to ON (restart).
The burner operates through a preliminary set algorithm, which is installed in its
control module. The optimal operation parameters are adjusted in the
manufacture company’s factory and their change is generally not required.
