1.4 GENERAL DESCRIPTION The wall hung gas boiler is a fuel gas-consuming appliance (natural gas or liquefied

petroleum gas) which has the role of turning the energy of the fuel into thermal energy by burning.

The boiler can be used in the “summer” mode, in this case the boiler functions only for producing domestic hot water, or in the “winter” mode, case in which the boiler functions both for the central heating of the housing and for preparing domestic hot water. In the “winter” operation mode, the demand of domestic hot water has a higher priority.

This model of boiler functions unsupervised due to its protection and control systems with which it is fitted.

All boilers in the EKO range are monothermal, which means that they have two exchangers: the primary exchanger for preparing thermal agent and the secondary plate exchanger for preparing domestic hot water.

In order to obtain an adequate comfort, in case of increased domestic hot water consumption, we recommend using a MOTAN boiler. Please refer to Annex 8 “Examples of thermal systems”.

If you decide to also install a MOTAN boiler, ask the installation technician or the service personnel to set the boiler for preparing domestic hot water at the value of 60ºC.

1.5 DESCRIPTION OF THE RANGE OF BOILERS The range of EKO boilers is composed of wall hung gas boilers, with rated output = 24,

respectively 31 Kw with the following design versions: a) Type: C32 SPV 24 MEF A b) Type: C32 SPV 24 MEF B c) Type: C32 SPV 24 ME C d) Type: C32 SPV 31 MEF A e) Type: C32 SPV 31 MEF B f) Type: C32 SPV 31 ME C

where: C32 – family of boilers S – with instant production of domestic hot water (without storage); P – with pump; V – with closed expansion vessel; 24, respectively 31 – the maximum rated output that the boiler may give, in kW; M – the burner is supplied by a continuous modulating valve; E – the ignition and the control of the flame are electronically-made; F – the forced scavenging of burning gases using the fan;

A – the fan with variable revolutions per minute; B – the fan with constant revolutions per minute;

C – natural draught, without fan. The boiler is designed to use gas from the following classes: G20, G25, G25.1,

G30/G31. The type of gas for which the appliance is calibrated is specified on the product label and

on the name plate.

3 MOUNTING-INSTALLATION INSTRUCTIONS The chapter addresses both to the qualified persons which contribute to the installation of

the boiler and to the beneficiary who is interested that the performed works to correspond to the safety operations standards of all the installations which contribute to the proper functioning of the boiler.

An incorrect installation can cause damages for which the manufacturing company is not held liable.

3.1 GENERAL INFORMATION The preparations for connecting the inlet/outlet installations, for the gas, central

heating, domestic hot water installations, and the connection to the electricity network are carried out by personnel authorized by ISCIR for the mounting/installation activity certified by the manufacturer.

THE INSTALLATION OF THE BOILER IS NOT EQUIVALENT WITH ITS PUTTING INTO OPERATION. The putting into operation must be done by personnel authorized by ISCIR and certified by SC KÖBER SRL VADURI BRANCH. The warranty is not granted without signing the putting into operation protocol by the authorized personnel and the company declines any responsibility as regards the warranty or the subsequent functioning of the boiler.

3.2 THE LOCATION OF THE BOILER

The boiler will be installed in rooms with ventilation in compliance with the legislation in force and which correspond from the perspective of the climatic conditions.

The boiler can be mounted only in rooms having a humidity of maximum 60% in the range of 20÷300C.

3.3 THE MOUNTING OF THE BOILER

3.3.1 UNPACKING THE BOILER The boiler is encased in a cardboard box. Inside the box, besides the boiler, you will

find: the set of two anchors and stove bolts, support plate necessary for the wall mounting of the boiler, as well as the technical documentation.

The inlet-outlet kit is packed separately, in a cardboard box.

3.3.2 PREPARING THE MOUNTING PLACE The mounting place of the boiler is established taking into account the assurance of

minimum spaces necessary for service operations (annex 1C), as well as the sizes of the boiler (annex 1B and annex 2).

The vertical wall, chosen for mounting the boiler, must be able to support its weight.





Form code F-02-15




3.3.3 FIXING THE BOILER ON THE WALL Two holes are made in the wall for the screw anchors using the support made of zinc-

platted sheet from the standard equipment of the boiler. The hole for the passing of the inlet-outlet kit is made (in compliance with the sizes

indicated in annex 1B and annex 2). The two anchors are fixed in the wall, after which the two stove bolts are threaded. The support of the boiler is fixed. The boiler is fixed on the support, so that it will be

well fixed in two profiles especially made on the central support bar. The stability of the fixing and the positioning on the wall are checked so that there

would not be straining of the structure of the boiler.

3.4 CONNECTING THE GAS BOILER

3.4.1 CONNECTION TO THE GAS NETWORK The entire gas supply installation must be made in compliance with the regulations in

force and sized so that the necessary gas flow of the boiler is also ensured for the other gas consuming appliances within the housing.

The gas supply installation must MANDATORILY include a pressure reducer, with an impurity filter.

The pressure reducer is not part of the standard equipment of the boiler and must be purchased separately.

The pressure of the natural gas at the entrance in the gas valve must be kept within the range of 20÷25 mbar.

The pressure of the gas if G.P.L. is used at the entrance in the gas valve must be kept within the range of 30÷37 mbar.

The maximum admitted pressure at which a gas valve holds is of 60 mbar. If the foreseen pressure is not observed noises can be produced due to a

turbulent burn or problems might appear at the internal regulator of the gas valve, which leads to the worsening of the combustion performances.

The gas supply connection (C connection – see annex 3 “Hydraulic diagram”)

must be of 3/4". The diameter of the gas installation will be at least equal with the diameter of the connection (3/4").

For the user’s safety, the entire gas supply installation, including the meter, must be checked in order to be sure there are no gas leaks!

The connection to the electricity network of the building must allow the full electrical insulation of the boiler in situations in which an intervention must be done, except for the disconnection from the protective earth.

3.4.3 THE AIR INLET – FLUE GAS OUTLET SYSTEM The boiler with forced draught is not supplied with air from the room (enclosure) in

which it is located, or from the neighbouring rooms. The charging of the air necessary for an efficient and non-dangerous burn will be carried out directly from the exterior atmosphere.

The boiler with natural draught has an open burn chamber and must be connected to the stack, the burning air is taken over from the room where the boiler is installed.

Recommended examples for mounting the air inlet/flue gas outlet system are

presented in annex no. 6, and the minimum distances that must be observed upon mounting the kit are presented in annex no. 5.

It is forbidden to install the boiler without grounding. The colour semantics will be taken into account: brown =

phase, blue = neutral, green and yellow = grounding.

3.5.2 ADDING WATER IN THE HEATING INSTALLATION

If the pressure of the thermal agent from the heating circuit drops under the recommended working pressure (1.560.5 bars), please follow the next steps:

- open the filling tap (black colour), located under the boiler, by unthreading it in the counter clockwise direction (please see the picture below).

- load the central heating circuit until the necessary pressure is reached (1.566660.5 bars).

- after reaching the required pressure in the installation, the filling tap of the central heating installation is closed by threading it in clockwise direction.

3.5.3 EMPTYING THE HEATING INSTALLATION

If you wish to empty the heating installation, unthread the filling tap (please see the picture above), but first turn off the running water supply of the boiler, then open a tap from the domestic hot water consumer and let the water from the installation to run off.

3.6 MOUNTING THE AMBIENT THERMOSTAT

The mounting of the ambient thermostat is made on one of the interior walls of the housing.

Do not mount the thermostat near heat sources, do not expose it to direct sunlight, near cold/hot water pipes, or in areas where it might be influenced by the air streams.

The ambient thermostat and the outdoor sensor are used for optimizing the consumption of electricity and natural gas and to create an increased comfort in the enclosure to be heated, respectively the building that uses the appliance.

The placing of the ambient thermostat is made so that its use ensures a maximum comfort. For this, we recommend placing the ambient thermostat at a 1.5 m height from the floor of the room, in the coldest space of the room.

The procedure to connect the ambient thermostat is performed by AUTHORIZED PERSONNEL!

3.7 MOUNTING THE OUTDOOR TEMPERATURE SENSOR

The placement of the outdoor temperature sensor is made on the exterior of the building.

Depending on the outdoor temperature and the dispersion coefficient, the working temperature of the thermal agent will increase or drop.

The use of an outdoor temperature sensor makes possible the enabling, by the AUTHORIZED PERSONNEL, of the “climatic compensation” function, which leads to the increase of the comfort level and to the reduction of the gas consumption when the boiler operates in “Winter” mode.

In this case, the water temperature from the primary - turn circuit is optimized depending on the climatic conditions. Thus, when the outdoor temperature increases, the water temperature from the primary –turn circuit drops according to the climatic compensation curve (please see the diagram below). The positions of points A, B, C and D, which define this curve, are established as follows:

- The position of point A: is established by the set value of the water temperature form the primary – turn circuit (central heating);





Form code F-02-15




- The position of point B: is established by the minimum value which can be set of the temperature on the central heating. This value is of:

- 300 C – for radiator-based heating; - 150C – for underfloor heating;

- The position of point C: is established by the authorized service personnel; - The position of point D: is established by the authorized service personnel.

4 NORMAL OPERATION

The authorized person that performs the putting into service is entitled to refuse the putting into service of the boiler, if he ascertains that boiler was not installed by authorized personnel, and will not complete the putting into service form until this problem is solved.

BEFORE THE USE, the authorized person that performs the putting into service is BOUND to thoroughly instruct the beneficiary regarding the following aspects: 1. The start-up and shut-down procedure of the boiler under safety conditions by mainly checking the following elements: - the electrical power supply; - the fuel supply (gas); - the supply and loading of the central heating circuit; - the filling tap should be closed; - the working pressure in the installation, by reading on the display of the control panel, should range between 1 and 2 bars; - the taps on the DHW circuit should be open;

2. The operation mode of the boiler and possible problems that might appear. The meaning of every button on the control panel will also be explained. 3. The beneficiary is warned that a drop of the water pressure in the system is caused by a leak of the thermal agent which must be solved before using the boiler. 4. Warnings are made on the measures to be taken against freezing. 5. This user’s manual of the boiler is handed in.

At the end of the training, a putting into service protocol is signed, in which the user signs that s/he acquired the knowledge on the correct usage method of the gas boiler.

The initiation of a burning cycle takes place in the following situations: • Heat demand in the central heating circuit; this could be triggered by:

- the decrease of the temperature on the CENTRAL HEATING – turn circuit under a certain threshold (for the operation in winter mode); if an ambient thermostat is connected, the additional condition for the initiation of a burning cycle is that the ambient environment temperature drops under the value set by the user;

- “Antifreeze” function. • Heat demand in the domestic hot water circuit. Upon the preparation of the domestic hot water in instant mode, this demand can be

triggered by: - the flow sensor upon the detection of a water flow; - “Comfort” function.

Upon the preparation of the domestic hot water in a storage tank, the heat demand

can be triggered by: - the temperature sensor on the tank when the temperature drops under the set

value; - “Antilegionella” function.





Form code F-02-15




4.1 OPERATION IN DOMESTIC HOT WATER MODE The boiler can operate in this mode during both seasons (winter and summer). The

heat demand in domestic hot water (DHW) mode prevails over the heat demand in central heating (CH) mode.

The temperature of the domestic hot water can be adjusted from the buttons of the control panel in the range 35 – 550C, for operation in instant mode.

The heat demand is triggered by the water flow sensor or by flow meter. The boiler tries to supply DHW at the set temperature. If the water flow is under 3 l/min, the electronic board does not modulate, thus the boiler operating at maximum power. If the heat demand is over the maximum power that the boiler can provide, the DHW temperature will be smaller than the set temperature, all the more so as the water flow is higher.

The temperature at which the burning cycle is activated on DHW, instant mode, is by 5°C higher than the set temperature, and the temperature at which the burning cycle ends is 15°C higher than the set temperature.

Upon the preparation of DHW in instant mode, the function COMFORT can be activated. This function allows the supply of DHW in the shortest time possible, by maintaining the boiler hot. When the function is activated, the boiler starts when the temperature read by the thermo-turn sensor is equal with the temperature set by the user for DHW and it stops when the temperature read by the sensor is 8 degrees higher than the temperature set by the user for DHW. If for an hour, no DHW demand appears, the function COMFORT deactivates automatically.

In the case of preparation of DHW in a storage tank, the heat demand is triggered by the temperature sensor on the boiler. In this case, the temperature set by the user is for water stored in the tank; implicitly, the tank tries to prepare DHW in the secondary exchanger at a 70°C temperature. The temperature at which the burning cycle stops is of 78°C.

In the case of the C32SPV24MEFA and C32SPV31MEFA boilers, upon the preparation of DHW in the boiler, the function ANTILEGIONELLA is activated automatically. This function allows that, once a week (default setting: Wednesday, within the time range 03AM ÷ 04 AM, if the chronostat is correctly set), for an hour, the temperature of the water in the boiler is maintained at the value of 65°C so that the potential bacterial colonies are destroyed.

4.2 OPERATION IN CENTRAL HEATING MODE

The boiler can operate in this mode during the winter season. Depending on the type of the heating installation (radiator-based or underfloor), the dedicated service parameter must be set at the putting into service.

The heat demand is triggered by the temperature sensor on the primary-turn circuit (TTS) when the temperature read by it is smaller by 5 degrees (in the case of radiator-based heating) or by 3 degrees (in the case of underfloor heating) than the temperature set by the user. The interruption of the burn takes place when the temperature read by the TTS is higher by 10 degrees (in the case of radiator-based heating) or by 5 degrees (in the case of underfloor heating) than the temperature set by the user; until the triggering of the next head demand, the pump remains operational.

If an ambient thermostat is connected at the electronic board, this actuates the operation of the boiler in central heating mode only when the environmental temperature is under the value set by the user.





Form code F-02-15




4.3 FUNCTIONS REGARDING THE SAFETY OF THE BOILER 4.3.1. Post-circulation of the pump - After each stop of the boiler, the pump remains operational for a period of time. Advantages:

a) prevents the standing of the water at high temperatures in the heat exchanger. Thus, the chalk deposits are significantly reduced. b) prevents the overheating of the water in the primary heat exchanger during the post-heating range.

4.3.2. Post venting After each usage of the boiler, the fan remains operational for a period of time in order

to completely evacuate from the boiler flue gas and, together with them, the water vapours that the gas contains. Thus both the electronic command circuit of the fan and the primary heat exchanger, which cools of partially, are protected.

4.3.3. Pump anti-blocking function If the boiler has performed not even one operation cycle for 24 h, the pump is put into

service for a few seconds in order to avoid its blocking due to possible chalk deposits. 4.3.4. Antifreeze function If the temperature sensor from the primary-turn circuit detects a temperature less than

8°C, the boiler is put into service in central heating mode. The shutdown of the boiler (cancellation of antifreeze function) takes place when the water temperature from the heating – turn circuit reaches the value of 25°C.

4.4 SHUTTING DOWN THE BOILER UNDER SAFETY CONDITIONS

In case the end user identifies that: - the boiler has a malfunction; - error codes are displayed repeatedly (as described in chapter 6),

s/he has the obligation to shut down the boiler as soon as possible and under maximum safety conditions.

In order to do so, the user must perform the following operations: - press the POWER button in order to cut off the operation of the boiler; - the boiler is disconnected from the electrical power supply circuit, by unplugging it. - the fuel supply circuit is disconnected by closing the gas valves; - the running of the domestic water and of the water from the central heating circuit is

shut down by closing the valves corresponding to these circuits. - After shutting down the boiler under safety conditions, the end user shall

immediately contact THE AUTHORISED SERVICE PERSONNEL.

5.2.2 DESCRIPTION OF THE FUNCTIONS AND DISPLAYED GRAPHIC CONTEXTS

5.2.2.1 STARTING THE BOILER Upon the start-up of the boiler (by using button POWER-J6), the boiler remains in an

initial state for 5 seconds, required for commissioning. From the user interface perspective, there are two possibilities according to the

previous state of the boiler: e) in case prior to disconnecting the board from the central network, its state is “ON”,

then on the symbol S1 (large digits) the welcoming message “HELLO” will be displayed (see picture 11);

f) in case prior to disconnecting the board from the central network, its state is “OFF”, then on the symbol S1 (large digits) nothing will be displayed (see picture 12);

Picture 11 – INITIAL context for the boiler state ON

Picture 12 – INITIAL context for the boiler state OFF

5.2.2.2 TURNED OFF STATE (STAND-BY) This menu context is corresponding to an inactivity state of the boiler. When the boiler is TURNED OFF, the elements of the gas boiler are inactive and no

central heating or domestic hot water cycle will be launched. There is however only one exception from this rule: when there is an Antifreeze command

(the temperature of the water in the installation is below 8oC), the central heating cycle will be initiated in order to protect the installation.





Form code F-02-15




The TURNED OFF context is activated when the button POWER (J6) is pressed for at least one second, thus causing the change of the operation mode of the boiler (from OFF to ON or from ON to OFF).

• RESET (J8): used to reset the potential errors (which require to be reset).

Picture 13 – STAND-BY graphic context.

5.2.2.3 TURNED ON CONTEXT In this state, the user can view all the information about the boiler and, respectively

can make the desired settings. In the TURNED ON context, there will be a passage from the TURNED OFF state

when pressing the POWER button for more than one second or from the user MENU upon completion of browsing through the list of sub-menus.

Example of graphic context for the TURNED ON state (active CHRONOSTAT function, the boiler is in burning state, the circuit is DHW, the operation mode: summer, active “Comfort” function):

Figure 14 – TURNED ON graphic context

• RESET (J8): used to reset the potential errors (which require to be reset).

5.2.2.4 THE USER MENU CONTEXT From the TURNED ON context, when pressing the MENU/OK button, the user

interface menu will be accessed. Using this menu, the user can set up certain operation parameters such as:

g) the temperature of the water from the central heating circuit; h) the temperature of the water from the DHW circuit; i) the set-up of the day of the week and of the time; j) activating/deactivating the “Comfort” function; k) setting the information regarding the CHRONOSTAT function (boiler activity hours); l) activating/deactivating the “Economic” function;

When first pressing the MENU/OK press button, the symbol S9 (central heating icon) will be lit up intermittently and on the symbol S1 the value of the desired temperature on the central heating circuit will be displayed.

Changing the value of a parameter from the user MENU context can be done by pressing the press buttons “+” and “-“ when the current index of browsing through is on the desired parameter. In order to get to the next symbol, respectively to the previous one, the press buttons P+ and P- will be used.

In the case of the SERVICE and CHRONO icons, pressing the buttons “+” and “-“ do not cause any change. The actions and the change of the parameters regarding the two icons will be discussed in the following sub-chapters.

In order to come back from the initial state, one must either press the press button P- when the active symbol is S9, or press the press button P+ when the active symbol is S15. In





Form code F-02-15




the case there is no activity from the user (no press button is pressed), after 30 seconds there will be an automatic reset to the initial context.

Picture 15 User MENU context

In order to increase the efficiency of the menu, you can notice in the above picture that the icons composing the menu are displayed when the user MENU context is active. The current icon is designated by being displayed intermittently.

5.2.2.5 CLOCK SUB-MENU This sub-menu is used to set the current day of the week and respectively the current

date, settings that are necessary especially for the Chronostat function. The sub-menu CLOCK is accessible by pressing the MENU/OK press button from the user MENU context.

Figure 16 CLOCK Sub-menu

5.2.2.6 CHRONO SUB-MENU By activating the CHRONO icon from the user MENU context, one can access the

sub-menu for viewing the chronostat settings. The display mode of the chronostat is made by day representation (from Monday till

Saturday), through 7 segments with the symbol of the 7 days in English, and by hours, with 24 bar segments in the bottom part of the display, according to the image below.

During the operation, the current day shall be activated, as well as the operation program of the boiler on that day. Thus, through the bar segment, according to whether they are activated or not, the boiler will operate or not during that time range.

For example: If the segments corresponding to the hours: 13, 14, 15, 16, are activated, the boiler will operate normally within the time range 13.00 – 17.00. Several time ranges can be activated for the same day.

Picture 17 – CHRONO state graphic context.

As follows, it is presented the module in which the chronostat functions can be changed. First of all, the “Chrono” icon is activated by using the desktop system (MENU/OK).

After activating this icon, the hours can be set (or the time range) when the boiler would operate, by days. The first day that can be selected is Monday (“Mo”), staring with 1 o’clock (the segment marked with 1 at the bottom of the LCD display).

The hours and the days that can be selected will “flash on” (will be activated by an intermittent light), the scrolling of the hours is made by using the buttons P+ and P-, the scrolling of the days is made by using the buttons + and – (it is possible to skip to the next day up or down at any moment of programming by hours from the previous days, except for the case when the beginning hour of a period has been selected and it is necessary to select





Form code F-02-15




as well the end hour of that period, during which the boiler should operate, when the Chrono function is activated), and the selection is done using the MENU/OK button.

For example: If you wish the boiler to operate on Wednesday, within the time range 13 – 15, you should proceed as follows: First press the MENU/OK press button, access the icons starting with the central heating symbol. Using the button P+, you reach icon “Chronostat” and select it using the MENU/OK button. After this selection, Monday and 1 o’clock will flash on intermittently. Using the button - , you pass from Monday to Tuesday and then to Wednesday. When Wednesday flashes on together with 1 o’clock, scroll using buttons P+ on the hours, until you reach 13. Using the MENU/OK button (press once), you select 13 o’clock (13 will stay lit up intermittently). You will scroll again using P+ until you reach 15 and you will select 15 o’clock, using the MENU/OK button. After this selection, the entire 13 – 15 (including) range will stay lit up. (if you wish to select only one hour for operation, you need to activate that hour by pressing twice the MENU/OK button). The icons corresponding to the days will be activated according to the current day (if the initial programming is performed correctly) for the entire operation period of the boiler (even if the chrono function is or is not activated), whereas the icons corresponding to the hours will be activated only during the CHRONO operation period.

In order to deactivate certain hours within a day, the procedure is similar with the one for setting an hour, the difference being that the press button used for deleting is P- (and not P+, like in the case of setting up). For instance, if you wish to delete the hours 13 – 17, press the press button P+ until you reach 17 o’clock, then press MENU/OK press button, then press P- until you reach 13 o’clock, at that moment you press one more time the MENU/OK press button.

5.2.2.7 ECONOMIC SUB-MENU In case the ECONOMIC function is activated, the gas boiler no longer takes into

consideration the temperature set for heating. In this case, the burning cycle for heating stops at 50ºC and reboots at 35ºC.
