Biomatic 50 the new generation pellet boiler is specically designed for pellet
heating. It is equipped with vertical convection tubes to prevent soot to stick
to the convection surfaces.
Biomatic 50 is equipped with an oversized ash box to facilitate maintenance
work. Sweeping is mainly done from the soot-hatch on top of the boiler but
also through the rebox door where the burner is located.
e boiler is designed to operate with a pellet burner.
Biomatic 50 consists of a combustion chamber with flue pipes, which is
enclosed by a jacket holding 115 litres of water. Heat generated by the
burner is transferred directly to the boiler water.
Oil heating
e Ariterm pellet boiler can also be used for heating with oil (oil heating
accessories on demand).

e boiler shall be positioned and installed according to the building rules in force.
Before installing the boiler, the chimney must be controlled for underpressure and
possible risk of condensation. It is possible that an air draught compensator has to be
installed. Inner pipe is recommended for minimizing the risk of condensation.
Space needed for installation: Minimum clearance in front of the boiler (burner
included) is 1000 mm. Clearence on the top shall be at least 0,5 m. By the other side
of the boiler clearence shall be at least 0,8 m. e boiler must be level. If the floor is
uneven, adjustments can be made with the help of four adjusting bolts (enclosed with
the boiler) that shall be fitted to the bottom plate of the boiler.
e air intake duct to the boiler room must have at least the same area as the flues.
Chimney installation
To embed the angular tube in the chimney, proceed according to the drawing below.
If the tube is embedded as described, you will be able to avoid soot leakage when the
chimney is being swept.
Flue connection and combustion air intake
e combination flue of the boiler allows for connection towards the top as well as
to the rear. Boiler cement is suitable for sealing. Recommended flue gas requirements
for Biomatic+ 50: brick chimney lined with a Ø 150 mm acid proof thin-walled tube
or an acid proof Ø 150 mm element chimney. Recommended underpressure in the
chimney is 25 Pa. e height of the gas flue shall be dimensioned according to the
building’s requirements, but should be at least 6 m. If condensation water comes out of
the flue, a condensate drain pan shall be installed in the lower portion of the chimney.
e combustion air intake must not be covered.

Water piping shall be carried out in accordance with current local and national hot
water and building regulations. Safety equipment shall be installed in accordance
with regulations in force. If a closed expansion vessel is used, an approved safety valve,
a pressure gauge, and a vent valve shall be fitted. e safety valve shall be fitted just
above, but not directly on, the boiler in such a manner that the connection with the
boiler cannot be closed off. e connecting line from the boiler to the safety valve must
rise continuously. Before the boiler is filled with water, the enclosed drain tap shall be fitted.
Radiator system and expansion vessel
When you fill the system, all valves must be open and the external circulation pump
turned off. Bleed the system carefully while filling. When the installation has been in
service for a few days, it shall be bled and refilled once again.
ATTENTION! See also separate instructions for filling of water.
e volume of the expansion vessel is determined as follows:
Open system:
5% of the water volume in the heating system.
Closed system:
Select the volume of the vessel in accordance with the manufacturer’s instructions.
In the following table, you will find examples of suitable closed system expansion
vessels.
System volume Opening pressure Initial pressure Vessel volume
(litre)* (bar) (bar) (litre)
70˚C 90˚C
500 1,5 0,5 35 80
1000 1,5 0,5 80 140
1500 1,5 0,5 80 140
2000 1,5 0,5 140 200
An open system with 500 litre water volume demands at least a 35 litre expansion vessel and a 1500 litre
system volume a 80 litre expansion vessel
* System volume = boiler volume + storage tanks + piping volume + radiator volume.
Planning and installation
Planning and installation shall be carried out in a professional manner, attention being
paid to general and local rules and regulations. Operating pressure is max.
1,5 bar. Before taking the installation into service, and always at the beginning of the
heating season, the following checks shall be carried out:
• that the heating system is filled and bled
• that the circulation pump is working
• that the system valves are open
• that the automatic control and safety devices are in working order
• that the chimney has the necessary draught and that the fresh air ventilation
is open.
Safety valve
If a closed expansion vessel has been installed in the radiator system, the safety valve
must be checked 4 times a year. Activate the valve by pressing or turning the control
button and check that water escapes from the overflow pipe connecting the valve to
the drain.
WATER PIPING

ARITERM SWEDEN AB Installation, Operation and Maintenance - 2007.10.26- 8/12
Before you begin heating, the heating system must be filled with water.
To fill the system, do as follows:
1. Open all shut-off valves, including the shunt valve.
e pump must be switched off.
2. Fill the boiler and the radiator system with water.
Bleed the system at the radiators.
3. Once the system is filled completely, the circulation pump can be started and
heating can begin.
4. When the boiler water has reached its pre-set operating temperature, the pump
should be stopped and the system bled at the radiators once again. is should be
repeated several times.
Remember that much air is enclosed in tap water. e enclosed air volume may reach
as much as 10%, which explains why bleeding takes time – especially where there are
large water volumes. A closed system shall be filled until the pressure gauge indicates
the correct system pressure, i.e. the distance from the pressure gauge to the highest ra-
diator in meter times 0,1 which gives the system pressure in bar. Adjust the red needle
of the pressure gauge to the same value as the big needle.
FILLING OF WATER MAINTENANCE, CARE, SWEEPING
Boiler cleaning
Burning solid fuels, even if operation is automated, normally calls for a little more care
and maintenance than oil heating. For Biomatic 20 maintenance has been minimized
as the result of well planned design and a big ash box holding 50 litres. Ash is removed
when necessary. e convection parts of the boiler are to be cleaned when the flue gas
temperature has risen by 20-30˚C above the temperature of a newly swept boiler.
ATTENTION! Pay special attention to the pellets quality when you receive a new delivery or when
you change supplier.
ATTENTION! Show a great care when emptying the ash as it might be glowing hot. Ash must be
kept in a fireproof container.
e following measures and checks shold be carried out when the boiler is cleaned:
•Switch off the burner an hour before service.
•Lift the soot hatch at the top of the boiler and brush clean the flues.
•Remove the fixing bolts from the burner and loosen the hose and electric connec
tions.
•Pull out the burner and brush clean the walls of the combustion chamber.
• Empty the ash.
ATTENTION! Disconnect the power to the boiler before removing the protective housing
ATTENTION! Show great care when emptying the ash as it can be glowing hot.

ADVICE ABOUT FUEL PELLETS
• Pellet fuel can be manufactured from several different biologically derived raw
materials. Most common is wood, but today there are several alternative materials
available on the market that are suitable for pellets manufacture.
ese raw materials have various characteristics that can be advantageous or disad-
vantageous for pelletised fuel.
Important factors that can be assessed are energy content, size, amount of fines,
moisture content and, last but not least, the price. We recommend that you choose
the fuel that has the lowest cost per energy unit after checking how the fuel per-
forms in the burner. Study carefully the fuel performance after new delivery.
In case of doubt, please contact us at Ariterm.
• Most of the problems that arise on account of inferior fuel quality are the result of
inadequate handling and storage before the fuel reaches the end customer.
If the fuel has high fines content the problem is usually due to separation
during storage or loading.
e formation of sintered ash is due to silicate contaminants (sand). eses
cannot be discovered before they are used. If you get pellets that produce
sintered ash, a claim must immediately be sent to the pellet supplier.
ATTENTION! If sintered ash is formed, the burn pot must be continuously
cleaned of sintered material (with a table spoon for example).
• Damp pellets can be the result of inadequate handling and transport.
If possible, inspect the pellets before they are unloaded to make sure that
you get clean and dry pellets and no fines.
ATTENTION! Damp pellets must be rejected immediately.

PELLET STORE
anks to the pellet feed system the pellet store can be built for bulk deliveries.
e store can either be located inside the house or in a separate building.
Pellets must, however, never be exposed to moisture.
Data for flexible feed system:
Maximum climb: 2,5 m
Maximum gradient: 45˚
Outside pipe diameter: 75 mm
Attention! The pellet store can have a maximum of 3 intake openings, and only one intake
can be used at a time.
e store shall be well sealed to avoid the spreading of dust. As a guide when determi-
ning the size of the store, it may be useful to know that the minimum bulk delivery is
normally 3 tons if you wish to avoid freight surcharge. 1 ton of pellets corresponds to
about 1,6 m3. To accommodate 3 tons of pellets you would need a store of at least 6
m3to have some space to spare.
