FOR THE NEW OWNER
In this guide, we have compiled the key facts on installation, operation and servicing.
Ariterm Oy’s bio-burners have been designed to be easy to operate and reliable, and
risks such as burn back have been eliminated through the introduction of several safety
systems. By observing the instructions in this guide, your burner will achieve optimal
operation. e quality of fuel used also fundamentally affects the ease of use.
e model of burner and level of accessories are selected at the order stage to suit the
needs of the customer. ese instructions are a general guide to the Ariterm Multijet
range of products. Because of this, there may be differences between the burner delive-
red to you and these instructions, due to different power ratings. During the installa-
tion stage, situations may emerge for which these instructions do not provide a direct
answer.

GENERAL
Ariterm’s bio-burners meet the most up-to-date operational and safety standards for the bur-
ning of bio-fuels. The Multijet is a burner equipped with a moving grate which is installed in
the burner compartment of the boiler’s firebox. The burner grate is located entirely inside the
firebox.
An automation system controls the burner by feeding it fuel and combustion air. The air is divi-
ded through separate fans into primary and secondary air, and the fuel is gasified in the burner’s
grate. The feed system may consist of one of more feed augers and a fuel stoker. The augers and
stoker are selected according to the fuel being used. The movement of the grate can be separate-
ly adjusted to suit each kind of main fuel.
Between the augers in the multi-auger systems is a sensor, which monitors the fuel feed to the
burner. If a conveyor stoker is part of the equipment, the automation system also controls this.
When using pellets as fuel, no special control is required for the silo.
The burner’s automation system controls the equipment based on the boiler’s water temperature
which is measured by a PT-100 sensor (with 4...20 mA transmitter). With the Arimatic control
unit (AM200, AM1000 or AM2000), the burner can be maintained on constant partial power
settings and reverts to its inactive mode only when the power requirement falls below the mi-
nimum level. In normal operation, the automation system runs the burner based on the power
requirement at a level between 21% and 100%.
The equipment must have burn back protection. Such equipment varies depending on the fuel
and feed system selected. Please note that the fuel selected also affects other parts of the equip-
ment.
ALWAYS CHECK WITH THE PRODUCT SUPPLIER ON THE SUITABILITY OF
THE FUEL FOR YOUR BURNER!

TRANSPORT, HANDLING AND STORAGE
The burner is packed at the factory for transportation and short-term storage. Depending on
the means of transport and place of storage, however, the package may require additional pro-
tection to ward off moisture, knocks, etc.
The burner is often part of a larger entity. If you are transporting the system by itself, in order
to avoid transport damage and for the sake of traffic safety it is important to tie the packages
together as well as possible and to secure them to the vehicle. The transport company is always
responsible for the correct loading and securing of the equipment.
Use caution when handling components in order to prevent damage.
The equipment can be stored in the open air if protected from rain and ground moisture. Long-
term storage, however, requires a better storage location. Storage indoors is recommended as the
equipment contains sensitive parts such as electric motors, sensors and a control unit.

Receiving delivery and handling
When you receive the delivery, check that the contents correspond to your order and that the
final inspection report and list of accessories are included. If anything is unclear, contact the
seller immediately.
Before commencing assembly, it is advisable to read not only these burner installation and
operating instructions carefully but also the installation instructions for the boiler, automation
system and fuel stoker.
This means you can ensure in advance that, from a point of view of successful installation, the
main facts and measurements are all satisfactory. Please note: Keep all operating and installation
instructions in a safe place where you can easily find them when you need them, for example in
their own folder in the boiler room.
The parts of the Ariterm bio-heating system should always be installed by an expert and in
accordance with requirements. We recommend that you carry out installation in the following
order:
1. Put the boiler in position with the burner attached, and ensure that the pipes and flue are
not yet connected.
2. Put the conveyor or other fuel stoker in position.
3. Fit the augers between the stoker and burner.
4. It is advisable not to carry out the final precise positioning of the boiler and fuel stoker un-
til the suitability of the augers has been checked. In the TPYM stoker, the stoker is fitted
to the floor and is the checkpoint for the system.
5. Plumbing and electrical work is done last.
Requirements concerning the installation and operating environment
• e boiler room must be built in accordance with the relevant regulations (E9 Building
Regulations, further information available from your local fire authority)
• Air vent in the boiler room wall. Recommended surface area 5 cm2 / 1 kW
• Installation and operating temperature 0 – +40 °C
• e humidity of the boiler room should be 20 – 80 % (in order to prevent condensation)
Necessary connections
• Electrical supply through the control unit to the actuators and instrumentation
• Flue in accordance with the instructions for the boiler to be used. Remember that the
correct negative pressure is important for the system to function properly!
• Water for the automatic extinguishing system (a powder extinguishing system is recom-
mended if pellets are used as fuel)
• Installation of the power unit of the stoker conveyor
• Connecting the hoses of the power unit that move the grates of the Multijet burner to the
burner’s cylinders
Space requirement
Please note that there must be sufficient space for the burner and burner auger between the
boiler and boiler room wall. When planning, it is advisable to make allowance for the possible
dismantling of the burner and burner auger/motor for maintenance purposes (e.g. door open-
ings). We recommend a distance of at least 1 metre between the boiler and the wall on the sides
where sweeping and maintenance work will be carried out.

MECHANICAL INSTALLATION
e system delivery usually also includes a boiler, burner auger, auger motor, automation system
and stoker. ese are selected based on the type of fuel and fuel stoker being used.
Installing the burner in the boiler
e burner can be installed in a solid fuel boiler, the power rating of which corresponds to the
power of the burner. e negative pressure required for the reliable and correct operation of the
burner (25-30 pa in the firebox) can be ensured either by a correctly dimensioned chimney or a
negative pressure-controlled flue gas extractor.
We recommend that compatibility with anything other than an Ariterm boiler is checked by the
burner manufacturer.
e burner is fixed by its flange to the boiler with bolts and the seam is sealed with heat-resis-
tant silicon (1). e joints must be sealed so well that they are completely air-tight! e bolts
are tightened diagonally. If the boiler opening and burner flange are of different sizes, for the
purposes of installation, a suitable installation flange must be made.
