Pellet burner GP 45 IV 25
The circulations water temperature sensor must be mounted in a muff for measurement of
the hot water boiler outlet water temperature or must be screwed in threaded orifice
(depending on the sensor type).
6.2.3. SWITCHING ON THE BURNER FROM SERIES “GP”.
The burner switching on is performed by the appliance power supply to which it is mounted.
If the burner has been in operation mode (or in “hot reserve”) but the power supply has been
interrupted, it automatically starts/continues operation when the power supply has been
restored.
During operation of the burner flue gasses are possible to flow through the
unsealed parts, eventually through the fuel inlet flexible pipe, if the appliance
to which it is mounted is not sealed properly. It is recommended to seal these
parts and to adjust the burner’s heating output in order to prevent flow of smoke
out of the appliance. The same effect can be monitored during the transition
seasons, autumn and spring, when the natural chimney draught is decreased
due to higher environment temperature.
The electrical heating elements, which are positioned over the combustion
chamber fire-grate, activate during the ignition mode. This zone heats to very
high temperatures and could be considered as a risk from burning, in case it is
touched by hand – it is not allowed to perform any manipulation in the
combustion chamber zone. If it is necessary to mix (spread) or remove fuel, then
proper personal protection equipment and tools must be used.
At initial burner operation start the fuel transport auger must be filled with pellets –
this is continues process requiring more time. The auger must be connected to
external power source through its standard plug and to wait until the pellets start
to drop down through the auger’s upper opening. After that plug the auger to the
burner’s main module power supply outlet.
The burner’s main module constantly checks if the fuel transport auger is
connected to it and if this condition is not fulfilled it activates an emergency
mode. In order to turn it back to normal operation mode the auger’s power supply
cable must be plugged in and the module restarted.
If the auger was plugged out of the burner’s main module (the controller reads
such situation as an emergency mode – i.e. no electric motor plugged) and the
burner was switched on, then an emergency mode activates and the burner does
not operate. In order to reset the alarm it is necessary to switch off and then back
on the burner’s main power supply, but after the auger has been plugged in the
burner’s main module.
The burner operates by preliminary installed algorithm based in its control
module. The optimal parameters for operation are adjusted in the manufacturer
company factory and their change is not required.
