The relief capacity of the pressure relief system has to refer to the nominal
heat output of the boiler!

Safety installations are not part of the purchased parts package.
6 Mode of operation
The wood pellets are stored in a pellet store (4). Out of the store the pellets will be transported by
an auger system (3). From the end of the auger system the pellets will reach the store of the burner
(5) through a plastic hose (2). The hose is part of the burner safety system. Only Janfire certified
hoses may be used.
There is a level sensor in the store of the burner. Until this sensor is not covered with pellets, the
auger system will run. Than it will stop. Because of the consumption of the burner the pellet level in
the storage will fall and after a while the sensor will not be covered anymore. The LED of the sensor
goes out. This process will repeat depending on the power output of the burner, its parameter can
be adjusted in the menu of the burner. If the level sensor is not covered after the maximal operation
time (adjustable in burner menu) a fault message will appear in the display of the burner. This case
normally happens at the first start running or if you run out of pellets!!!
The internal dosing auger of the burner (6) transports the pellets according to the power output of
the burner from the storage to the dropshaft. The pellets will fall down the dropshaft into the burner
bowl where the combustion proceeds. The combustion air is transported by a fan according to the
power output of the burner into the burner bowl. The ratio from pellets and air has to be adjusted
during the setup process. An optional lambda-sonde, which does this adjustment automatically, is
available too.
The burner is equipped with an electric ignitor. During the startup process a part of the combustion
air is heated by the ignitor and inflames the pellets. Two temperature sensors are monitoring the
combustion process.
When the burner stops, the deashing system is cleaning the ash out off the burner bowl into the ash
pit of the boiler.
Make sure that the boiler room is vented properly. To avoid back burn it is compulsory that there is
an under pressure in the boiler compared to the boiler room in every mode of operation.
