ARITERM SWEDEN AB Installation, Operation & Maintenance - 2008.11.18- 4/28
OPERATING PRINCIPLE
e Ariterm Bionet combines a compact pellet boiler with an Ariterm BeQuem
combustion chamber into a single reliable and ecient unit. e convenience, envi-
ronmental performance and eciency are optimised to meet the demands of ease-of-
use and ecient pellet combustion. Ariterm Bionet has a vertical convection system
that reduces deposition, which allows the boiler to retain a high coecent of eciency
in between servicing. Servicing needs depend on pellet quality and output eciency
(fuel consumption) and varies seasonally. e large ash box hold 20 litres and is easy
to remove and empty.
Automatic controls
e control system is specially designed for pellet combustion and permits ecient
control at 3 dierent settings. e control display provides information about current
operating conditions such as boiler temperature, exhaust temperature, rate of pellet
consumption, amount of remaining pellets in storage, warning functions, etc.
Versatile supplemental heat
e Ariterm Bionet can advantageo-
usly be adapted to existing waterborne
heating systems. e Bionet is an easy
maintained, convenient and economic
choice in combination with modern oil,
rewood, heat-pump or solar-energy
powered systems. e 12 kW output
is sucient for most detached-house
heating systems. For domestic hot water
needs, the Bionet can benecially be
connected to a separate hot water storage
system pre-prepared for solar energy.
Ariterm Bionet’s compact shape permits
installation even in tight spaces.
Chimney-sweeping
Sweep soot from the boiler via the combustion chamber door and cleaning hatch at
the top of the unit. Use a ue brush to clean all convection surfaces. Remove the
burner and clean the combustion chamber walls.
NB!
Always use caution when handling ashes, as some may still be glowing. Ash should be
kept in a re-proof container.

SAFETY AND ALARMS
e boiler is designed according to the same main principles as an oil heated system.
e advantage of this pelletsystem is easy and comfortable handling, as the location of
the fuel store does not depend on the layout of the boiler room. From the safety point
of view, the separation of fuel store and burner in combination with interrupted fuel
supply between the two means high security.
In the event of temperature sensor failure, the high-limit thermostat stops ope-
•
ration to prevent the boiler from overheating. e burner automatically resumes
normal operation after power failure or interrupted fuel supply.
Equipment failure leading to operation stop is indicated by a red LED combined
•
with a message on the display panel indicating the cause of the failure.
In case of fuel shortage, there is also an audible alarm.
e boiler design is outstanding with safety as an integral part of the function. As
•
the fuel supply is interrupted and corrected in the burner auger pipe before the
boiler wall, there is no continuous fuel line capable of transferring heat outside the
boiler wall which means that you do not have to rely on extra safety devices.
For details about the various alarm conditions please refer to ”Troubleshooting”.
Each time lling takes place, only a limited
amount of pellets is transported through
the external feeding system from the storage
bin to the top feed connection. To make
sure that the correct amount of pellets is
supplied from the top feed connection to
the burn pot, a separate supply auger has
been installed immediately under the top
connection controlling the supply of pel-
lets through the air lock and burner auger.
As the burner auger is feeding pellets to
the burn pot three times a fast as they are
supplied, a safety zone containing only a
few seperated pellets is created between the
air lock and the burn pot. is safety zone
is always kept intact even in case of power
failure, insucient maintenance or equipment
failure. In consequence, safety has become
an integral part of the burner functionality.
