DESCRIPTION OF THE BOILER

EKO-CKS

is a special steel boiler for central heating systems. It has been

constructed on the basis of a long term experience. The boiler is engineered for
solid fuel firing. Its nominal thermal output is achieved through solid fuel (Hd>15000
kJ/kg). The  steel  body  of  the  boiler  is  welded  according  to  modern  technology,
produced out of high quality material and tested in compliance with EN-303-5 norm.
Boiler`s  efficiency  rate  reaches  over  75%.  It  is  constructed  for  a  maximum
operating pressure of 4,0 bar. The entire surface inside the boiler which comes in
touch with fire or with smoke is in contact with water and its tubing net has water
cooling. Flue gases are streaming through three passages of exchanging surfaces:
combustion chamber, first bundle of boiler flue exhaust and the second bundle of
boiler  flue  exhaust  tubes.  After  that  they  are  coming  out  through  the  smoke
chamber  and  through  the  chimney  connection.  The  firing  procedure  is  manual
through the spacious door. The temperature , i.e. fire intensity is regulated by the
underperssure  lid  in  boiler  flue  exhaust  and  properly  sized  fan. Additional  firing
regulation can be achieved through the secondary air door which is situated on the
lower boiler's door. The upper boiler door enables the access to the first and second
bundle of the boiler flue exhaust tubes and their cleening. There is also free access
to all other doors and openings when the boiler has to be cleaned. The boiler is
equipped with all necessary connections for the connection to the central heating
system. The  body  of  the  boiler  is  delivered  separately  from  the  casing  and  the
thermal  insulation  which  enables  easier  transportation  and  assemblage  without
unnecessary risks.

WARNING:
Connection of the boiler to the chimney and to the central heating system as
well as the start-up has to be performed by the authorized person licensed on
behalf of Centrometal d.o.o. company.

14.3.

ASSEMBLING THE BOILER REGULATION

After the holes have been perforated, through the bigger hole the tap should be
inserted (included in delivery package) and pulled through the sensors, supply and
the wires for the connection with the fan (Image 10).

Before assemblage of the boiler cover, 3 holes should be made on the lower side of
the cover: on the

right lateral

(or

left lateral

side), which depends upon the position

of the boiler in the heating room - (see plan for the boiler casing EKO-CKS on the
page 13). The 2 holes should have diameter of Ř3,5 mm for screws and also one
bigger hole (Ř22,3 mm) should be made for sensors, supply and connection to the
fan. The Image 9. shows places where the holes are to be made.

CONNECTION TO THE CHIMNEY

Properly dimensioned and built chimney is the main condition for safe and
economical functioning of the boiler

. The thermal insulation of the chimney has

to be done properly

, it has to be absolutely gas-proof and smooth. On its lower

part there has to be built in the opening for cleaning with the door. An brick-layed
chimney has to have three layers with an insulation of 30 mm in the middle, if the
chimney is built inside the house (i.e. inside the heated area), or an insulation of 50
mm if it is built outside the house (i.e. outside the heated area). The flue gas
temperature has to be at least 30°C higher then the temprerature of their
consdensation point. The choice and the construction of the chimney has to be
performed by the authorized person.

3.1.

DIRECT CONNECTION TO THE CHIMNEY

Inside dimensions of the chimney intersection depend of its height and of the
capacity of the boiler (Image 3.). Prescribed maximal distance between boiler and
the chimney is 700 mm, minimal distance 300 mm. Boiler flue exhaust angle has to
be 30° to 45° (Image 1). In order to unable condensate to enter the boiler, the flue
exhaust pipe has to be situated 10mm deaper inside the chimney. The

pipe

connecting the boiler and the chimney has

to have a thermal insulation made

out of 30-50mm thick stone wool. If for any reason the boiler has to be connected to
the  chimney  dimensioned  for  higher  capacity  boilers,  the  possibility  of
condensation  inside  the  chimney  shall  be  highly  inreased. The  boiler's  function
shall  not  be  affected,  but  the  damper  on  the  flue  exhaust  has  to  be  positioned
according to the chimney underpressure (see technical data regarding the chimney
pressure for each type of the boiler).

3.2.

CONNECTION THROUGH THE CYCLONE AND FAN DRIVE

In case of the connection through the flue gas fan the height of the chimney can be
reduced for 50% regarding the read value (see Image 3). The cyclone is directly
connected to the boiler and the distance between the fan and the chimney shall be
determined by enabling the smooth maintaining of the cyclone, flue gas fan, boiler
and the chimney.

The cyclone and connecting tubes have to be coated by an

30-50mm stone wool termal insulation.

THE ROTOR AND THE FAN'S HOUSING

Both parts are subjected to the wear and tear. The main reason is dust, i.e. the acid
mixed with the medium inside the tubes, steam and gases. The wear and tear grade
depends on the kind and quantity of the substance. During the rotation the rotor
could slip out of its center, which causes the damage of bearings, of the axle and of
the rotor itself. Because of the material wear and tear the solidity of the rotor can be
minimized, which leads to its break down as well as to a heavy damage of the fan.
The rotor and the housing have to be checked once in the month. During the
operation process of the fan, there has to be payed special attention to its smooth
moving, i.e. the vibration level has to be checked. The cleaning of the rotor depends
of the dust quantity. Depending on general conditions (wear and tear of the rotor,
higher dust stickiness) the controls have to be repeated in shorter periods.

CONNECTION OF THE BOILER TO THE CENTRAL HEATING INSTALLATION

The boiler has to be connected to the open system according to the Image 4. All
connections  from  the  boiler  to  the  open  expansion  vessel  and  from  the  open
expansion  vessel  to  the  boiler  have  obligatory  to  be  covered  by  the  thermal
insulation  of  min.  40mm  (stone  wool  or  equivalent  insulating  material).  If  the
expansion vessel is situated outside the heated area, it has to be insulated. The
dimension of the open expansion vessel is determined by the quantity of water
inside the installation, i.e. approximatly 7% of the total water quantity inside the
entire installation.

5.1.

CONNECTION OF THE BOILER TO THE OPEN EXPANSION VESSEL

5.2.

BOILER SAFETY PUMP

In order to minimize the condensation inside the boiler a safety line with an safety
pump has to be build in (Image 5.). Activating and disactivating of the safety pump is
steered by the pipe valve situated on the boiler's outlet, approx. 300 mm from the
safety line connection point, towards the installation with an functioning field of 0°C
to 65°C. Safety line suggestions according to the boilers' capacity is shown by the
table „TECHNICAL DATA“. Safety line has to be covered by thermal insulation, min.
40 mm stone wool or equivalent insulating material.

5.3.

CONNECTION OF THE BOILER TO THE CENTRAL HEATING SYSTEM

The central heating system to be connected to the boiler has to be performed
according all professional and security standards. The regulation of the room
temperature can be solved in few ways, but each of solutions has to be worked out
in order the outlet water operating temperature does not reach the value below
60°C.

It is recommended to build in the 4-passes manual valve

. In order to

minimize the water steam condensation of the flue gas, it is necessary the
circulating pump of the heating circuit/s to be activated and disactivated by means
of the pipe thermostate set up to min. 75°C. The system can also be regulated by
means of any other appropriate system. The pipe thermostat has to be situated on
the boiler's inlet right next to its connection to the boiler. The general connection
plan is figured on the Image 5.

Additional equipment-fan

13.3.

CONNECTION OF THE FAN TO THE ELECTRICAL POWER NET

This connection has to be performed only by an authorized person. Technical data
concerning the motor are attached in the technical manual and are also written on
the motor body. The rotation sense of the fan is indicated on its casing and has to be
considered. The cable has to be protected from mecanical or other kind of
damages, set in the proper way, in order to avoid any damages. Connection plan to
the electrical power net is shown on Image 7., page 22.

13.4.

STARTING THE FAN

First to be checked if the fan is properly fasten to the cyclone. Revolve the fan
manualy and find out if it is rotating without touching any obstacle. The rotor is not
allowed to touch its housing! During its first start up it is necessary to start the fan
when the draught regulator is closed or otherwise closed air flow, in order to enable
the motor to reach the speed easier. During the first short start up it is necessary to
control the fan rotation sense (sense of the arrow). It has also to be checked if
during the start up some kind of strange noices are appearing. Check the vibrations
and find out if they are exceeding the normal range.
The damper for the balancing of the fan which is situated on the flue exhaust of the
boiler and should be put in the position which enables the flue exhaust gases
temperature to reach minimum 160°C - 180°C at nominal thermal output.

While the motor is running it is necessary to control the temperature of the motor
and its bearings. The motor housing temperature should not exceed 70°C (constant
operation). If the bearings are getting warmer the fan has to be stopped and the
reason for the exceed temperature has to be found out.

13.5.

TEMPERATURE OF THE FAN BEARINGS

13.6.

MAINTAINING THE FAN

After each 6000 working hours, i.e. once in the year it is necessary to: check the
general condition of the fan; check all elements and screw joints; check all welding
points, especially those on the rotor; check the wear and tear of the motor housing
and of the rotor; check the condition of the compensator and belonging steerings
(tightness, wear and tear). In case the spare parts are needed, they have to be
cleaned previously.

FILLING THE SYSTEM

The boiler and the entire central heating system have to be filled with water
according to the EN norm.
The system has to be airvented in order the water can circulate normaly.

Assamblage of the thermal insulation and plastified metal sheet coating can be
started after the boiler has been connected to the chimney and to the central
heating installation. If the boiler regulation is planed for the fan, before assembling
the boiler casing, the regulation has to be fixed. The order of assembling is
described on Image 6. and the plan which is attached to the package.

CONNECTION OF THE CONDENSATE OUTPUT

During the first heating process, usually by means of solid fuel firing, when the
temperature in the boiler is below 65°C, a certain quantity of condensate produced
by water steam appears on the cold walls of the boiler. In order to let this
condensate get out of the boiler, in the left lower corner of the upper boiler's door
(see page 3) there is an output. It is connected by an 1/2“ inside thread to which a
flexible plastic/gum pipe can be connected which is draining the condensate into
the plastic pot, or simply out of the boiler.

Assembling order for the casing

Insert the lower lateral part of the insulation (1) into the slit D in order it fits into the
lower boiler casing porter (see detail Y), in the same time put the lower part of the
casing into the lower slit.
Fix the upper lateral part of the insulation (2) onto the upper porter of the boiler (see
detail Z), while the lower part of the upper lateral insulation plate is fixed on the porter
of the boiler according to the detail Y.
The sensor of the thermometer has to be inserted into the probe on the upper side of
the boiler and the upper front cover (3) has to be hanged over the hooks A and fixed by
screws B on the casing (2). The same has to be done with the upper back cover (4).
The stone wool has to be placed on the upper side of the boiler. After that the cover (5)
hast to be placed on the plate (2) as well as the cover (6) being fixed into the slit (5)
(detail X).
The back side plate (7) and then (8) has to be fixed on the boiler and fixed together by
help of the screw C, successively to the lateral plates of the boiler (1).
Before assembling the front insulation plate (9) take off the side air opening, then
open the lower door and pull through the front insulation plate over them. After this
step we adjust front insulation plate on the pin A on the left and right plate (1), and put
back the side air opening.

START UP OF THE BOILER

Additionaly following has to be checked:

- the boiler and the central heating system have to be filled with water and airvented.
- the security elements are functioning and if they are correctly connected.
- the flue connection tube is well connected, insulated, and sealed.
- flue gas lid is properly set according to the chimney underpressure.
- all objects, which eventually could have been left inside the boiler are removed
(from the combustion chamber, exhaust tubes, etc.). Some objects could have
been put inside during the assemblage for any reason and could negatively
influence the functioning.
- the upper and lower door of the boiler is well set (seal properly).
- the primary air/cleaning door properly fits.
- the draught regulator is put in the proper position and if it is properly connected
with the chain to the primary air/cleaning door (in case of cyclone - opening of
draught regulator must be watertight sealed).
- the secondary air regulator on the lower boiler door is closed.
- the side air opening can freely open/close, when the boiler does not work, side
air opening must be closed.
- the heating room has proper air circulation.
- the tube thermostate of the boiler's security pump is set to 65°C (the pump is
functioning from 0°C to 65°C).
- the tube thermostate of the heating circuit pump is set up to 75°C (the pump is
functioning above 75°C).

Firing the boiler, cleaning and maintaning

FIRING THE BOILER

The  boiler  is  constructed  to  be  manualy  fired  by  means  of  solid  fuel.  Nominal
thermal output is obtained through solid fuel and its lower calorific value Hd>15000
kJ/kg.
After the initial firing the fuel has to be supplied in the way the boiler reaches the
temperature of 70°C as soon as possible in order to minimize the intensity of the
initial condensation.
The  functioning  of  the  draught  regulator  (in  case  of  cyclone  -  uderpressure
regulator lid and fan regulation) has to be set in the way the temperature inside the
boiler during the normal combustion does not exceed 90°C and does not fall below
75°C.
It  is  also  necessary  to  take  care  of  the  outlet  water  temperature  during  the
operation, because it should not fall under 60°C.
Additional regulation of the combustion quality can also be reached by setting the
secondary air opening.
Between two firing, it is recommended to pass over the glow with the poker in order
to obtain a balanced fresh air supply. It is also necessary to take care of all other
previously mentioned points of this technical manual.
The fuel has to be dry as usualy recommended for this kind of firing, for example,
two years long air dried wood, i.e. the wood has to contain less then 30% humidity.

The space under the grate and the combustion chamber has to be cleaned every
day. The space under the grate can be cleaned through the primary air/cleaning
door, which previously has to be removed without separating the chain of the
draught regulator. Clean of the flue exhaust tubes of the second and third passage
when necessary or once a week through the upper boiler door with the brush which
has to be pushed through the whole length of the tube. On the back side of the boiler
there is another opening for cleaning (see page 3.) through which is possible to
remove the material which has been collected during firing as well as during the
cleaning process. The hole can be approached by removing M8 screws and covers.
If there is a possibility of freezing, the boiler has to be fired constantly. Draining the
water out of the system is absolutely not the right solution, because this would
cause corrosion of the entire central heating system as well of the boiler' interior.

The start up procedure includes also

- starting of at least one heating process during which the functioning of the draught
  regulator  (in  case  of  cyclone  -  uderpressure  regulator  lid  and  fan
    regulation) has to be set, so that the temperature inside the boiler during a normal
  firing process does not exceed 90°C and does not decrease below 75°C.
- check the outlet water temperature during functioning, because this temperature
should not be under 60°C. If it happens the system should be accordingly set up.
- secondary air flow is set (can also be closed)
- training the person in charge of the boiler room, training protocol signed by the
trained person.

The start up has to be done by the person authorized on behalf of
Centrometal d.o.o.

It is necessary the check if previous assemblage has been performed exactly
according to the requirements and description of this manual.
