Very important information, always read it if it is present.
TIP!
It is worth reading this information, it makes it easier to use.
4. Definition of terms used in this manual
(USER/INSTALLER)
Central heating boiler - a device for burning various types of solid fuels to heat the heat
carrier (usually water) circulating in the central heating cycle.
Draft limiter - a device whose task is to regulate temperature in solid fuel boilers. As the
temperature rises, the airflow to the furnace is limited, which slows down the burning of fuel. As
the temperature decreases, the air inflow increases, which makes it possible to ignite the fuel
again.
Chimney draught regulator - is used to stabilize and reduce excessive negative pressure in
chimney ducts.

11. Fuel
(USER)
The fuel for SE series boilers is deciduous firewood with humidity not exceeding 20%, hard
coal of OI range.
It is recommended to use deciduous wood such as: beech, hornbeam, oak, birch, alder, ash.
The use of coniferous wood is not recommended, as it causes the boilers to smoke and requires
more frequent cleaning.
NOTE!
When using wood with moisture content of more than 20%, it is advisable to use
an acid resistant steel insert in the flue pipe.
12. Requirements for the boiler house
and boiler installation
(USER/INSTALLER)

NOTE!
More detailed information on the requirements for the construction of a boiler
house can be found in the Regulation of the Minister of Infrastructure
dated March 12, 2009.
TIP!
The aforementioned provisions are guidelines that should be reviewed as the
regulation is subject to revision.
13. Boiler installation
(USER/INSTALLER)
An important part of the installation is a correct positioning and leveling of the SE type boiler,
these boilers do not require special foundations. The boiler must stand vertically.
NOTE!
An improperly leveled boiler can be damaged.
The boiler must be placed on a heat-insulating, non-flammable pad that is 2 cm larger on each
side than the base of the boiler. If the boiler is located in a basement, it is recommended that it be
placed on a foundation of at least 5 cm. The strength of the foundation as well as the fire
protection conditions are key guidelines when placing the boiler in the right location, these
include:
●20 cm safety distance from flammable materials;
●40 cm for flammable materials of flammability grade C3;
●40 cm if flammability is not known.
NOTE!
The return water temperature from the system to the central heating boiler should
not be lower than 45ºC.
NOTE!
It is required to connect the boiler to the heating system using a four-way valve.

system
(INSTALLER)
Boiler connection to the central heating system should be performed by a firm authorized by
the manufacturer, and the fact of proper connection should be confirmed on a warranty card
attached to this manual. Boiler should be connected according to producer recommendations, in
accordance with this manual.

15. Requirements for the expansion
vessel
(INSTALLER)
Every open heating system should be equipped with a collecting vessel whose task is to absorb
the increase in the volume of water filling the system and to vent it. The vessel should be installed
in the highest point of the system, if possible in a vertical line above the boiler(s).
The volume of the collection vessel can be estimated by taking the unit volume in relation to
one kW of thermal capacity is 1-2 dm3.
The vessel is equipped with a ferrule for the connection of a tolerable safety pipe, a
precipitation safety pipe and an overflow pipe with associated vent.
The diameter of the vent pipe and the overflow pipe shall be at least:
[MM]
- boiler output [kW].
The most important requirements for safety devices are as follows:
●the vessel should have a volume of approximately 3.5% of the volume of water contained
in the heating system including the boiler;
●Every boiler should absolutely have a safety pipe and an overflow pipe;
●The system should be equipped with a signalling and collecting pipe and a venting stub for
the collecting vessel.
If several boilers are set up, each of them should be equipped with a safety pipe according to
the given rules in PN-91/B02413 - protection of open-system water heating installations. No shut-
off valves can be installed on safety and overflow pipes, and the pipes and vessel should be
protected against freezing.
16. Boiler connection to the electrical
installation
(INSTALLER)
The boiler is designed for connection to 230V/50Hz. Installation should be made by a qualified
person. The socket outlet 230V/10A with earthing should be easily accessible. Boiler power supply
and boiler room lighting should have a different circuit.
Completion of the installation and the heating test must be recorded in the Warranty Card. The
completed Warranty Card should be sent to the manufacturer's address by the user in order to
register the user in the company's system.
NOTE!
The first start-up of the boiler must be carried out only by a service technician
trained by the manufacturer, with a valid certificate of METAL-FACH Authorized
Service Provider, METAL-FACH Distributor or a person holding the SEP license up
to 1.5 kW.
17. Connection of boiler to chimney
(INSTALLER)
Smoke ducts
The purpose of flue pipes is to reliably carry exhaust fumes to the outside and to draw in air
for fuel combustion. The chimney draught required for this depends on:
●Temperature difference between hot exhaust gas and cold air;
●effective chimney height;
●chimney section not less than 20 x 20 cm;
●the execution of the chimney (as smooth internal surfaces as possible) and the tightness of
the joints;
The effective height of the chimney is the difference in height between the highest hearth and
the exit of the chimney. The effective height of individual chimneys must be at least 4 m and
common chimneys for solid and liquid fuels at least 5 m. The difference in height between two
fireplaces must not be greater than 6.5 m.
In the case of sloping roofs, chimneys should end at the ridge (the highest point of the roof), in
the area of free wind flow. This avoids draught disturbance. Always pay attention to the position of
the building in relation to other buildings.
Chimney selection
In most cases an approximate method or selection according to chimney manufacturer's
chimney diagrams is sufficient for selecting the chimney. in special cases (unfavourable pressure
and temperature relationships, large flue gas volume) chimneys are calculated according to PN-EN
13384-1+A2:2008 standard.
Chimneys for solid fuel boilers
Please note that solid fuel stoves with a nominal heat output >20 kW and without a fan need
their own chimney. For solid fuel stoves, single-layer brick chimneys can be used. Nowadays three-
layer chimneys with smooth surfaces and good thermal insulation are used.
Flue
The boiler is connected to the chimney by a flue pipe and a flue duct. Smoke ducts are pipes
and fittings that are laid indoors. Smoke ducts meet fire safety requirements concerning chimneys
and are often made of the same material as the main chimney. Smoke ducts should be made of
non-combustible products. Smoke ducts or casing should meet the requirements specified in the
Polish Standard concerning fire testing of small chimneys. A 12 cm thick solid brick housing, built
on cement-lime mortar with external plaster or pointing, is acceptable. Joints should be as short as
possible and laid with an elevation to the chimney to avoid heat loss and additional resistance.
They shall not be routed to other floors. Flue pipes should not be laid in rooms where fireplaces
cannot be fitted, nor should they be placed in walls or ceilings. In order to protect the chimney

15
against dampness and draught limitation, acid resistant or ceramic chimney liners should be used,
with condensate draining to the sewage grid. A distance of at least 6 m should be kept between
the chimney and the nearest edge of a tree crown.
18. Commissioning the boiler
(USER/INSTALLER)
Before you start a fire in the boiler, check if the central heating system has been properly
made and if it is properly filled with water - up to the overflow pipe from the vessel.
For filling the entire system or for making up for losses, softened/chemically treated water,
distilled water or rainwater would be most suitable.
In addition, check that the grate is cleaned of any unburnt fuel, ash and slag from the previous
firing and that the ash has been removed from the ash pan.
Recommended firing-up (correct firing from the top) - fill the prepared grate deck with fuel
(when burning wood - full load - to the bottom edge of the inlet, put logs across the boiler) Place a
kindling layer (paper, wood pieces) on the surface and set the fire. The boiler should be started up
with the primary air dosing flap in the lower door (grate and ash door) open, and with the
secondary air throttle in the charging door.
Boiler operation in the upper combustion system takes place in a system with cyclical fuel
filling, which means that after complete burning out of the fuel portion poured into the
combustion chamber and removing ash, the chamber is filled again and a new fuel portion is
ignited with the use of kindling fuel.
We do not recommend firing up the fuel "from below" in top-firing type boilers.
Before lighting the kindling layer, make sure that the chimney provides sufficient draught.
Insufficient draught is most often encountered when the boiler is started up for the first time or
after a longer break in operation, when the boiler and the chimney have cooled down.
To check the chimney draught, place a lit piece of wood close to the air inlet duct with the
damper open.
If you find that the flame is not being drawn intensively into the boiler, this indicates
insufficient chimney draught.
In this case, before setting the layer on fire, the chimney must be "warmed up" by proceeding
as follows:
●Put a few sticks of wood in the flue pipe and set it on fire;
●Keep the fire going until the chimney draught increases (the flame is drawn up the
chimney);
●After the wood has burnt out, scoop the unburnt residue and dispose of it in the ash pan.
When the boiler reaches the required water temperature, it is necessary to adjust the
combustion intensity. The combustion intensity is adjusted by a proper setting of the adjustment
screw of the primary air dosing flap and by a proper adjustment of the secondary air throttle.
During normal boiler operation it is necessary to periodically check and replenish the fuel as
specified above. In the case of hard coal, strike the hook to cause the fuel to fall down.
When opening the fuel door, be very careful, because if the door is opened abruptly, explosive
gases (degasification products) can be ignited. When opening the fuel door, stand at the side of
the boiler, slightly open the door, wait for a moment until the combustion gases are discharged
from the fuel tank into the chimney and then slowly open it. Do not stand in front of the door
opening. A similar procedure should be followed when opening the other doors during boiler
operation.
NOTE!
If for any reason there is a lack of water in the boiler - mains system, do not
top up with cold water. Cool the boiler down to the temperature of 30°C as soon
as possible and only after the boiler has cooled down, add water and start
burning again.
NOTE!
The flow of cold water on the boiler walls when the boiler is hot can cause
an explosion of the boiler and consequently damage the heating equipment. In
extreme cases, it can cause damage to buildings and injuries to people.
NOTE!
When opening the door do not stand in front of the boiler, it can cause burns.
When starting up the boiler cold or for the first time, a phenomenon of "sweating of the boiler"
can occur. This gives an impression of leakage. In this case, it is necessary to carry out an intensive
burning process (70-80ºC) to dry and warm up the boiler and the flue for even 2-3 days.
To increase the service life of the boiler it is recommended to keep the flue gas temperature
180ºC above the ambient temperature, and the boiler water temperature should not be lower
than 60ºC.
Maintaining a suitably low radiator temperature in this situation during autumn or spring can
be achieved by, among other things:
Correct boiler selection according to the size of heated rooms;
Use of three-way or four-way mixing valves between the water supply and return, manually or
automatically controlled.
Inadequate insulation of the expansion (overflow) vessel can also cause a boiler explosion with
all its negative consequences.
Frozen water in the expansion vessel breaks the connection between the central heating
system and the boiler and the atmosphere, and when the temperature of the boiler water rises,
the pressure in the system increases uncontrollably, which may result in a boiler explosion.
19. When using the boiler, remember
(USER)
●The boiler may only be operated by adults who have read the operating manual;
●It is forbidden for children to be near the boiler without the presence of adults;
●If flammable gases or vapours get into the boiler room or during the work, in which there
is an increased risk of fire or explosion (gluing, painting, etc.), the boiler must be switched
off before such work is started;

16
●When cleaning carbon in the retort, trough, the boiler should be turned off ("OFF"
position);
●When adding fuel to the tank, turn the boiler off ("OFF" position);
●Do not use flammable liquids for firing up the boiler, the boiler should ignite automatically
(by means of an igniter);
●When cleaning the boiler, turn the appliance off ("OFF" position);
●The boiler must not overheat in any way during operation;
●Do not place flammable objects on the boiler or in its close vicinity;
●When removing the ashes, flammable materials must not be located within 150 cm of the
boiler;
●The ashes should be put into heatproof dishes with a lid;
●When the boiler is operated at a temperature lower than 60°C, the steel exchanger may
dampen and cause corrosion due to low temperature, which shortens the exchanger's life;
therefore the temperature during boiler operation must be at least 60°C;
●After the end of the heating season the boiler and the flue pipe must be thoroughly
cleaned;
●The boiler room should be kept clean and dry.
NOTE!
The product is not intended for use by persons with reduced physical / mental
capabilities or lack of experience and knowledge, unless they are supervised or
instructed by a person responsible for their safety.
NOTE!
Any unauthorised interference with the electronics or the design of the boiler is
prohibited.
20. Cleaning and maintenance of the
boiler
(USER)
NOTE!
The boiler may only be cleaned when the appliance is switched off from the mains.
To save fuel it is necessary to keep clean the combustion chamber and convection ducts of the
boiler. It is necessary to clean walls and grates in the combustion chamber through the charging
and furnace doors. Boiler exchanger and ash collector must be also cleaned regularly.
The convection ducts (ducts) and the flue pipe must be cleaned through a cleanout on the
boiler flue and at the bottom on the side wall. Cleaning should be done with wire brushes on
extension tubes. The above actions must be performed during periodic boiler standstill, preferably
every 100 hours of boiler operation. Thorough cleaning of the boiler should be done once a
month.
In the case of combustion of poorer grades of fuel, these operations should be carried out
more frequently.
21. Instructions for disposal of the
boiler at the end of its service life
(USER)
Before scrapping the boiler, all electronic components must be disconnected from the boiler.
They must be disposed of in accordance with the European Directive 2002/96/EC on the disposal
of electronic and electrical equipment. For correct disposal, contact the manufacturer of the
electronic components according to the above mentioned European Directive.
Steel elements from which the boiler is made should be scrapped in designated places (scrap
metal purchase).
NOTE!
Do not dispose of the old boiler, intended for scrapping, or its components with
general waste.
22. Examples of equipment failure
