Safety provisions
During the use of the boiler, its individual parts: chimney, door,
individual points of the body - can heat up and cause burns if
touched.
Do not allow children to touch or use the boiler without adult
supervision.
The boiler can be operated by a capable adult who has
carefully familiarized himself with this instruction.
Only a qualied specialist can install the boiler and connect it
to the heating and electrical systems.
If you suspect that the boiler has malfunctioned, please
contact the organization that installed the boiler or
the manufacturer’s representative. Do not under any
circumstances use a malfunctioning boiler.
Improperly connected and used boiler can cause injury or
death.

1.1 General information
The Agro Uni boiler models are characterized by an
exceptionally large heat exchanger, which allows to achieve an
efciency of more than 90 percent, and very good tray pellet
burners with a wide range of control options.
Before connecting the boiler to the heating system carefully
read this manual to ensure that all boiler components and
equipment are working properly.
Agro Uni boilers are designed for heating private residential
houses, commercial and auxiliary premises. The boilers belong
to the so-called low-temperature boilers category, i.e. the
average temperature of the heat carrier cannot exceed 90 °C,
and the maximum operating pressure - 1.5 bar.
The manufacturer has the right to make minor changes
that do not signicantly affect the quality of the combustion
process and the operation of the boiler. We do not recommend
equipping the boiler with a stainless steel chimney.
1.2 Standards and regulations
The boiler must be installed and operated in compliance with
the legal requirements of the country to which it is supplied. It
must be installed in accordance with the requirements of the
maintenance and installation instructions.
Otherwise, the manufacturer assumes no responsibility and
does not guarantee repair for any defects.

3.2 Boiler
The boiler heat exchanger consists of three main zones. Four
horizontal heat exchangers (three in the 15 kW boiler) are
placed in the area of the upper door (3). The upper door is
used when it is necessary to clean the surface of the heat
exchanger. There is a solid fuel combustion chamber in the
area of the middle door (5). This chamber is designed to use
cheaper solid fuel which is loaded manually. The middle and
lower chambers are separated by cast iron grates (7). It is
recommended to remove the grates during continuous ring in
automatic mode. The tray burner (8) is installed on the side of
the boiler and is connected to the fuel chamber. A blower (19) is
installed on the side of the boiler, near the fuel supply pipe. The
burner has a built-in mixer that helps burn difcult burning fuel
(9). A pull-out ash box (11) is placed under the burner for ash
removal. An air valve is installed in the front of the lower door.
The boiler controller (2) is installed in the front part of the boiler.
The internal heat exchanger is made of bent and welded heat-
resistant steel sheets, and the nish is made of powder-coated
sheets. Underneath the boiler is an insulating layer of glass
wool, which protects against heat loss through the boiler’s outer
walls. Double doors are sealed with heat-insulating material
and painted with heat-resistant paint. Gases generated during
combustion are removed through the chimney pipe (1) installed
in the upper part of the boiler.

3.3 Pellet chamber
The pellet chamber is designed to store fuel and supply it to the
boiler in automatic mode. The delivery system can be on the
left or the right side, depending on the order. Fuel is loaded into
the chamber by opening the lid. Fuel falls down to the bottom,
where it is fed to the burner through a feed pipe with the help of
a screw-type feeder. After opening the tank maintenance cover
(17), we can access the cleaning opening. It is designed to
periodically clean the accumulated pellet dust, which reduces
the performance of the pellet feeder.
3.4 Burner
Agro Uni boilers use „Zenono“ tray burner that can burn lower-
quality, difcult burning pellets and other fuels: wood pellets,
grass pellets, grains, oats, beans. A fuel mixer is installed
together with the burner, designed to facilitate the burning
of extremely difcult burning fuel. This is a high quality, long
lasting new generation burner, designed to burn pellets and
other fuels. This is the only (and without any competition)
burner designed and manufactured in Lithuania. Reliable
construction and quality components will allow you to use this
burner for a long time.
3.5 Controller
An Inter Electronics controller is installed in the boiler. The
controller is a modern electronic device designed to control the
operation of the pellet boiler using data from various sensors.
The device is compact and easy to install. It can control the
central heating and hot water circuits and the burner.
3. Construction
The temperature of the heating circuits can be determined by
the data received from the main temperature sensor or the
room thermostat, which turns off the boiler pump.
When connecting the thermostat, it is necessary to ensure the
minimum heat demand for boiler operation in standby mode.
The compatibility with standard room thermostats allows you
to maintain a comfortable temperature in all premises (rooms).
Controlling the boiler is easy and simple. The controller can be
used in households and small industrial facilities.

Agro Uni boilers are equipped with a pellet chamber of 400 or
600 liters.
We do not recommend equipping the boiler with a stainless
steel chimney.
4.1 Location and position of boiler and pellet chambers
The boiler and pellet chamber must be placed on a hard,
smooth and non-ammable dry surface. It should be
convenient to access the bed burner, blower, controller, pellet
chamber, and fuel supply system, ash collector and other
mechanisms. The pellet chamber can be on the left or right side
of the boiler depending on the order. The door opening direction
can be changed.
