2. INTENDED USE OF A BOILER
SAS AGRO-ECO boilers with a fuel tank and an automated feeder are desig-
nated for water central heating systems, open vented or sealed*, with gravitational or forced water flow, secured according to current specific national or EU
regulations (PN-EN 12828+A1:2014-05 Heating systems in buildings. Design for
water-based heating systems). They are recommended, in particular, for heating of
residential flats in one-family or multi-family houses, commercial, services, catering and workshop facilities, etc., in which water supply design temperature does
not exceed
gas pass 0.30 – 0.55 mbar, depending on the device output (according to PN-EN
13384-1:2015-05 Chimneys. Thermal and fluid dynamic calculation methods. Part
1: Chimneys serving one heating appliance).
These boilers may also work with domestic hot water systems through a heat
exchanger of any producer that meets current standards. The boiler cannot be
used as a continuous flow water heater. The SAS AGRO-ECO boiler is also not
intended to be used as an air heater.
A boiler for heating a building should be selected on a basis of an energy heat
balance of that building
or EU regulations (PN-EN 12831:2006 Heating systems and water based cooling
systems in buildings – Method for calculation of the design heat load).

devices for water-based heating equipment in open vented systems,and expansion vessels in an open vented or sealed
systems (concerns boilers of up to 100 kW) together with accessories: diaphragm expansion vessel, pressure relief
valve, equipment for control and measurements, or devices for removing excess heat.
*) inner partitions (components in contact with fire) are made of 6 mm thick boiler plate steel P265GH (8 mm thick plate
boiler steel 16Mo3 for boilers exceeding 78 kW); the external shell of the water jacket is made of 4 mm steel plate (5 mm
for boilers exceeding 78 kW).

NOTE 1:
The boiler should be installed and operated only in conditions meeting those
specified in the operation and maintenance manual (manufacturer documentation delivered together with the device)!
NOTE 2:
Any changes in the design aiming at adapting the boiler to perform functions
not intended by its manufacturer are strictly forbidden and result in a loss of
warranty rights and documents associated with the product!
3. BOILER DESIGN AND OPERATION
The
SAS AGRO-ECO heating boiler is a low temperature central heating boiler
adapted to high performance, fully automated firing of biomass in form of
wood granulate (pellets of parameters specified according to EN 14961-2) and
oats. Biomass other than wood , in form of dry fruit stones (e.g., sweet cherry,
cherry, etc.) can be used as alternative (substitute) fuel, of parame-ters
conforming to EN 14961-6, see Chapter 6 "Fuel".
Basic boiler components are listed in Fig. 6 and Fig. 7.
The boiler consists of a body constructed of welded steel plates
The boiler water jacket forms a double-walled cuboid divided with water partitions.
The furnace chamber is located under a high-performance convection heat exchanger.
With the boiler structure based on three-pass layout of a flue gas duct, flue gas
heat is fully recovered. Also the upper part of the furnace chamber is closed with
a water jacket.
Flue gases are directed to a stack through a flue located in the upper part of
the boiler.
A clean out door, a firing/feed door and an ash box door are installed on a front
wall of the boiler. The front clean out door and the firing/feed door provide access
to the furnace chamber for maintenance operations and periodic cleaning of convection ducts of the boiler. The ring/feed door is also used for manual (emergency, e.g., lighter failure) firing of the boiler in the automated fuel feeding mode and
can be used as a feed door to stack the boiler when it is operated in the "emergency" mode (fuel burned on the steel grate). The ash box door is provided with a flap
in its bottom part, dosing air flow into the "emergency" burning process. The door
of a side clean out hatch is used to remove ash formed during furnace operation.
The whole heat exchanger structure is covered with an insulating material in
form of mineral wool, filling the space between the exchanger and the boiler casing.

, and pipes.
NOTE:
The flue gas temperature (semiconductor PT1000) sensor is installed in the flue,
controlling the burning process and reducing stack losses (controlling a blower
fan) A terminal block facilitates its quick and easy replacement, whenever necessary (see Fig. 1).
7
Figure 1 Flue gas temperature sensor installed in a flue
NOTE:
For correct operation of a controller controlling the burning process – work of the
automated fuel feeding system – periodic cleaning of dust and soot deposits from
the sensor surface is recommended.
Due to an overpressure in the whole inner space of the boiler, it is provided
with fire doors and inspection hatches with circumferential sealing (ceramic rope,
gaskets) and screwed connection, ensuring for its tight closing. Furthermore, it
is also provided with adjustment systems for hinges, and for closing systems for
doors and a fuel tank cover.
Non-flammable insulating materials were installed to reduce heat losses and
secure against excessive increase in a temperature of external boiler surfaces. The
heat exchanger surface is insulated from the environment with external cladding
of powder-coated steel sheets, under which a thermal insulation layer of asbestos-free non-flammable mineral wool is installed. The insulating material tightly
fills space between the exchanger and the boiler casing (powder-coated external
insulation metal sheet). Boiler doors are insulated, reducing heat losses. Door or
clean out hatch handles are made of non-flammable components significantly reducing heat transfer, Mobile components (gearmotor, gear wheels and chain system driving the fuel feeder, mobile grate drive, blower fan) located under a hopper
are secured against direct access with additional removable covers. Furthermore,
for safety reasons, a pictogram informing a user about presence of the mobile
components was used.
8
The fuel tank is provided with a loading opening with sealing and a closing
system. The design of the tank equipped with the hopper ensures free transport of
fuel (gravitational discharge).
Additional protection against flashback was installed in form of a pressure
equalising system in the hopper, which is also used for drying and ventilation
(preventing corrosion).
A hot water connector is welded to the upper part of the exchanger, while a return water connector is welded to a bottom part of
the side wall. A discharge connector is located on
a side wall in the bottom part of the boiler. It is also
used for connection of cooling water (from a water
supply system) when overheat thermal protection
– a thermostat valve (a device removing excess
heat, according to Fig. 10 and Fig. 11) is installed.
A connector (G 1/2”) for a temperature sensor
with a capillary tube, L=150 mm, is installed on
the side wall in the upper part of the boiler, see
Fig. 2 (excluding boilers above 100 kW).
Figure 2 Location of a temperature sensor with
a capillary tube– thermal protection sensor
The fuel hopper (tank), together with the feeder drive mechanism and the
blower fan, is installed in the back part of the boiler, behind its body.
Adjustment feet with the adjustment range of 30 mm ensure the boiler final
alignment versus the floor. The user is responsible for possible installation of adjustment feet, according to guidelines provided in this instruction (Fig. 8).
A characteristic feature of SAS AGRO-ECO boilers is an automated high-performance self-cleaning furnace burning precisely the amount of fuel necessary
to
obtain the temperature set on a controller by the user. Furnace components
exposed to high temperatures are made of stainless steel and ceramic materials. Ceramic panels used in the furnace ensure optimum conditions for
biomass burning (an optimum temperature for oats burning is 1200 °C) and
increase fur-nace effectiveness, while they have a positive effect on its life.
Fuel from a tank is fed automatically with a screw conveyor (a system with two
screws and a transfer duct).
The funnel-shaped fuel tank ensures gravitational fuel transport through a loading opening from a fuel tank to an upper fuel feeding pipe with a screw installed,
then fuel is transported gravitationally through a transfer duct to a lower distribution pipe in which the second screw is installed. With this screw fuel is supplied
to the furnace chamber. The screws are rotated by gear wheels driven by a chain
driven by a gearmotor. Safe fuel transport between the upper screw, the bottom
screw and the furnace chamber is only possible due to correctly selected number
of teeth in transmission wheels. All processes leading to burning of supplied fuel
in air supplied with the blower fan installed under fuel tank casing take place on a
9
grate in the furnace chamber. The supplied air is separated in the air chamber. The
initial air is supplied under the grate, while the secondary air is pumped through
a system of nozzles in ceramic panels into the fuel burning zone. The appropriate
– depending on a type of burned fuel – stream of air supplied by the blower fan is
controlled with a manual knob located on the boiler side wall.
The furnace grate is divided into a fixed part and a section of moving fire bars.
The cyclically activated moving grates driven by an eccentric mechanism remove
fuel burning residues, i.e., ash, particularly in form of sintered slag, from the furnace space to the boiler chamber. This solution maintains the furnace space of
the burner in a "clean" condition without interrupting the continuity of the burning
process. After a clean out cycle the moving grates are placed in slots of the lower
part of the furnace. The grate is positioned with a position control sensor (Hall
effect sensor, see Fig. 3, Fig. 6 and Fig. 7).
Figure 3 Moving grate positioning sensor (Hall effect sensor ).
NOTE:
Correct operation of the moving grate mechanism requires a correct setting of
the Hall effect sensor. A distance between the position sensor and the wrapping
connector of the moving grate should be 3 to 5 mm, these components should be
aligned axially.
The fuel feeder design developed at ZMK SAS, using a set of two screws,
is protected by an application No. W.120870 issued by the Polish Patent Office.
Additionally, for easier operation the boiler is equipped with a ceramic heater,
firing fuel during the boiler start-up (fuel self-firing). An automatic fuel firing and a
system to maintain flame after the set temperature is reached ensures an efficient
operation of this boiler even during periods of low demand for heat (an option
for continuous operation or operation with a domestic hot water tank during the
summer).
10
A microprocessor controller automatically controls operation of the fuel feeder,
the blower fan, the fuel igniting heater and the furnace cleaning mechanism.
During the final phase of biomass burning, a residual negligible non-flammable
part of fuel – ash – is transferred to the ash box chamber equipped with a removable ash drawer that should be emptied periodically (ash resulting from biomass
burning can be used as valuable ecological fertiliser for soil enrichment).
An efficiently working boiler furnace burns the amount of fuel necessary to
maintain the temperature set on the controller by the user. Thus, the controller
continuously measures a temperature of water in the boiler, and on this basis appropriately controls operation of the boiler operational components. At the same
time the controller controls operation of pumps: central heating, domestic hot water, floor, and circulatory (when the heating system is equipped with pumps). In a
system equipped with a mixing valve with a cylinder, the mixer can be controlled
directly from the boiler controlled. Connection points for circulatory pumps, temperature sensors and the mixer are located on the boiler side wall (see Fig. 4, Fig.6
and Fig. 7).
Figure 4 Connection terminal strip supplying control equipment
(note: the photograph shows an example of connection layout, details are provided in the controller operation and
maintenance manual).
The module (see Fig. 4, Fig.6 and Fig. 7) controlling furnace operation is located under the insulation upper lid. The module controls the fuel igniting heater
and the mechanism for furnace cleaning together with the positioning sensor (Hall
effect sensor). The temperature controller installed on the boiler controls operation
of the blower fan, the fuel feeding mechanism, and the feeder temperature sensor.
Cooperation between the module (Fig.6 and Fig. 7 item 32) controlling the burner
and the main boiler controller (Fig.6 and Fig. 7 item 14) is possible due to RSbased wired communication.
11
Figure 5 Module controlling burner operation.
The boiler controller* is also adapted to operation with a room temperature
controller.
Advantages of the boiler include its simple operation in form of periodic supplementing of fuel in the tank (hopper: every 1 to 3 days, depending on weather
conditions and building insulation) and removing of ash from the ash drawer without a need to put the boiler off. After firing the boiler does not require continuous
operation, and apart from periodic planned maintenance, it can be used in general
throughout the heating season. The boiler can also be used outside the heating
season in a system with a domestic hot water tank.
A boiler room with a solid fuel boiler is not maintenance-free and requires
periodic monitoring. During boiler operation certain daily activities must be
performed (e.g., verification of the furnace operation), to prevent emergency
situations.
Generally, the SAS AGRO-ECO boiler is operated automatically (in a continuous mode) using a unit consisting of the gearmotor-driven fuel feeder, the
self-cleaning blower furnace, and the digital temperature controller.
Additionally, the boiler is adapted to operation in the "emergency burning"
mode, e.g., in the event of power outage or failure of the feeder/fan (see details
in chapter 8.2.2). Then the boiler runs using a natural flue gas flow, therefore, the
boiler operation in this mode does not require any power supply. In this mode a
temperature of water in the boiler can be checked with an analogue thermometer.
The burning process can then be controlled manually with a screw adjusting air
supply in an air-dosing flap. The boiler is equipped with a bracket for installation of

troller operating manual attached to this documentation.
12
an emergency steel grate. This grate is not a standard boiler equipment.
It is forbidden to burn plastic materials; this may result in blocking of air
distribution openings and contamination of the furnace plate. Contamination
of the heat exchanger surface leads to reduced boiler efficiency and deterioration in the burning process. It is forbidden to use flammable materials
(such as petrol, kerosene, or solvents) for boiler firing, as this may result in
a fire or explosion.
To ensure safe operation, the SAS AGRO-ECO boiler is equipped with a security system consisting of several steps. The protective devices include protection
against flashback into the fuel tank through the fuel feeder (a temperature sensor
in the fuel route), a set of two screws separated with a transfer duct, and a thermal
switch protecting against boiler overheating.
The feeder in the SAS AGRO-ECO boiler, equipped with two transport screws,
consists of two fuel distribution pipes separated with the transfer duct ensuring a
distance between them. Feeders previously available in the market particularly for
biomass, were equipped with a single screw mechanism. This system requires an
additional protective device to be installed, securing against uncontrolled flashback to the fuel tank. For this purpose, an extinguishing system based on a thermally activated valve and an external water tank is used. When temperature in the
fuel supply system rises, the valve is opened and water is poured over the furnace.
After this procedure the boiler furnace and chamber must be thoroughly cleaned,
and those operations are very labour- and time-consuming. This mechanism protects against uncontrolled flashback into the fuel tank in boilers, without a need
to install the extinguishing system. The feeder in the SAS AGRO-ECO boiler was
designed to eliminate a risk of flashback from the furnace chamber to the fuel tank
during the normal operation or the fuel feeder downtime, as well as during power
supply outages (no power supply).
The system monitoring the boiler operating equipment guarantees the boiler
is automatically switched off in the event of the fuel feeder blocking, failure of the
system driving the moving grates, flame extinguishing in the heating chamber, etc.
In the event of power outage the operational status and all controller settings are
remembered, therefore, when the power supply is restored, the boiler is started
automatically, bringing the system to the required temperature.
