Installation and commissioning can be done only by a company authorized and agreed by KÖBER SRL-Vaduri Branch! This company will assume responsibility for the correct installation and commissioning.

8.1 Conditions for the installation of the central heating BOILER

8.1.1 Installation indication

The central heating BOILER will be subject to corrosion from the moment it is filled with water! To receive warranty during the entire warranty period it is essential to take into consideration the following directions in order not to increase the corrosion!

- The burning gas must have the sulphur content within the limits of the applicable European standard: it is accepted for a short period of time to have a maximum of 150 mg/m3, but the yearly average must be of 30 mg/m3. - The burning air must not contain chlorine, ammonia, alkaline agents, halogenated hydrocarbs, freon, plaster particles, lints, dirt or dust; - Installation of the central heating BOILER in the proximity of a swimming pool, washing machine or cleaner can result in the contamination of the burning air with these compounds. - Water pH must be within the following limits: 7,5<pH<9,5 It is recommended to check the water and thermal agent pH frequently and if the value does not fall within the limits provided by the manufacturer, it will be treated again. - Water asperity must be within the limits 5°F <TH <15°F (5°F (French degrees), equivalent to 50 mg CaCO3 or an equivalent quantity of other Ca and Mg salts). - It is recommended to have repeated BOILER startup cycles with the fuel tap off in order to air the installation. The BOILER is also provided with a manual ventilator, installed on the heat switch. - If the central heating BOILER is not used for a long period of time during the cold season, full emptying of the installation is recommended to prevent damage caused by freezing.

8.1.2 Protection of the BOILER in order to keep the warranty

Before and during installation, the central heating BOILER must be kept away from impurities: construction dust, sand, copper dust, fats etc as well as welding splashes, scoria. In any of theses cases, the installation must be washed with clean water mixed with a highly concentrated cleaning agent. Genereally, in order to keep the warranty it is necessary to apply any neccesary treatment to prevent the contamination of water with the following: � Black mud (magnetite - Fe3O4) formed as a result of the continuous electrolyte corrosion occurring in any installation which is not protected with an inhibitor. � Red mud (rust - Fe2O3) produced during oxidation. � Calcarous deposits produced especially on the hottest areas of the central heating BOILER.

A combination of these three factors mentioned above causes the majority of the problems occurring with heating systems. Caution! The presence of these substances (black mud/ red mud/ calcarous deposits) means that the standard measures to prevent problems of the heating system were not observed.

This is one of the causes resulting in losing warranty!

REV.12.06.2017 7 din 26

8.2 Gas connecting pipe

Danger! Danger of death by poisoning and explosion because of breeches in the gas pipes and connections in case of incorrect installation! Installation of gas pipes is allowed to be performed only by an authorized agent. During installation all legal stipulations, as well as the local regulations of gas distribution companies are to be observed. When installing the gas pipe it is essential that it is not tensed so as not to create areas of leakage!

Caution! Maximum safety pressure for the gas valve is 60 mbar! Going above this pressure limite may resul in damage. Work pressure with G20 natural gas functioning must be 20 mbar! Caution! Is is obligatory to istall a pressure regulator on the fuel input circuit, adjusted at 20 mbar. Caution! In case parasite voltage appears on the gas pipe, it can be insulated by installing an electroinsulating piece

(according to the Technical Norms for the planning and execution of natural gas input systems). Central heating BOILERs C13SPV36MEF, C14SPV25MEF function on GN natural gas. The gas connecting pipe is made of stainless steel with an interior diameter of 12.4 mm. The gas input pipe must not have a diameter smaller than that of the gas connecting pipe of the central heating BOILER. The fuel input must be done according to applicable legal stipulations.

8.3 General directions for the heating installation

When designing the central heating system, please take in consideration the hydraulic characteristic of the pump that equips this boiler model! See chapter 11.3 for pump characteristic.

Caution! Before connecting the central heating BOILER carefully wash the entire heating installation! In this way, you eliminate from the pipes various debris such as welding splashes, scoria, grummet, putty, dirt or similar. Otherwise, these substances can form deposits in the heating switcher and can cause damage or malfunctioning. Caution! It is obligatory to install an impurity filter on the return of the thermal circuit installation! When installing connecting pipes it is essential for these not to be tensed to avoid creating areas of leakage! Maximum working pressure allowed is 3bar. Recommended working pressure is 1.5 bar! Caution! It is forbidden to use the central heating BOILER without thermal agent or partilally filled – danger of explosion! It is forbidden to use the central heating BOILER if it is not completely aired!

The equipment is provided with a 7l capacity and 1 bar loading pressure expansion vessel. Before installing the equipment, check whether this volume is sufficient. If not, an additional expansion vessel must be installed on the aspiration side of the pump.

Caution! Check the pressure inside the expansion vessel before commissioning. Pressure inside the expansion vessel must be 0.8÷1bar.

8.4 General directions for the hot water circuit

Connect the central heating BOILER to the hot water installation.

It is obligatory to install filters to de-harden the water and a mechanical impurity filter on the cold water input connecting pipe!

Caution! When installing connecting pipes it is essential for these not to be tensed to avoid creating areas of leakage!

The apparition of pressure shocks (input pressures higher than 3-4 bars in addition to symoultaneously activating quick closing taps) can affect the components of the hydraulic circuit inside the central heating BOILER. We recommend the installation of a pressure regulator adjusted to 3-4 bars! Damage caused by the apparition of pressure shocks or by the use of higher pressure than recommended on the cold water input circuit is not covered by the warranty! We recommend the installation of a pressure regulator! Damage caused by the use of pressure higher than recommended on the cold water input circuit is not covered by the warranty! It is forbidden to install one-way valves on the the cold water input circuit. The cold water input pipe of the hot water preparation circuit will always be open (closing the network is done only by activating the taps at the consumer points) to allow take-over of possible dilatations on this circuit.

Note! It is recommended that the distance between the hot water connecting pipe of the central heation BOILER and the nearest conumer is minimum 6m of pipe. Otherwiswe, there is always the risk of hot water burns.

8.5 Connecting pipe of the condensation output duct

Danger! Danger of death by leakage of burning gases!


REV.12.06.2017 8 din 26

The condensation output duct must not be water-proof connected to a used water pipe because otherwise the internal condensation seal box can be emptied by aspiration and the burning gases can get inside the room where the central heating BOILER is installed. The condensation resulting from the condensation of water vapours contained by the burning gases is taken out of the BOILER by means of the condensation output seal box (fig.1.5), which is located in the lower part of the central heating BOILER. As this condensation is acid with a pH of approximately 3.8÷5.4, the output must be done by means of a plastic tube (flexible) with an interior diameter of minimum Ø25 mm or larger, which is connected at one end to the hose of the seal box and at the other to a sewage pipe.

Before commissioning the central heating BOILER approximately 1/2 liters of water must be introduced by means of the burning gases output connecting pipe (fig. 1.4), to form a “water plug” inside the seal box – in this way we prevent burning gases to be evicted in the room. The route of condensation output must be continuously downwards (so as not to have areas of condensation stagnation, especially in areas where there is the danger of freezing). The route of the condensation output must respect the applicable norms regarding residual waters.

8.6 Connecting pipe of the safety valve

Caution! Danger of hot water burns!

The connecting pipe of the pressing of the safety valve is connected to the drain pipe to the sewage system. Otherwise, there is always the risk of flooding, for which the manufacturer of the central heating BOILER is not responsable.

8.7 Air inlet pipe / burnt gases outlet pipe

The central heating BOILER does not require air plugs in the room where it is installed. The air necessary for burning to ensure the efficient functioning of the central heating BOILER must to be taken from the outside of the building. The equipment is delivered with a co-xial or dual type air input/ burnt gases output system called an evacuation kit. The equipment is delivered with a standard co-axial evacuation kit. On demand, a dual evacualtion kit can be delivered. It is also possible to order additional 45° and 90° corners as well as 0.5m and 1m elongations for both the dual and the co-axial systems.

Caution! It is obligatory to place central heating BOILER in rooms with proper ventilation systems according to applicable

norms. Study the technical instructions before mounting/ installation, commissioning or maintenance or repair work. Under no circumstances the total length of the co-axial kit, including elongations, is to be longer than 3 m (without the first corner). Under no circumstances the total length of the dual kit, including elongations, is to be longer than 5 m (without the first corner).

Danger! It is completely forbidden to use the central heating BOILER without the burnt gases output pipes because it endangeres people’s life and health of people.

Replacement is to be performed only by authorized personnel following applicable laws and using only original spare parts provided by the producer.

8.8 Electric grid connection

The central heating BOILER must be connected to one-phase network of 230V - 50Hz with protection null. Dispersion withstand of the earthing switch (earthing) must comply with applicable norms (maximum 4 ohm, and the working null must not have residual current). Electric powering of the central heating BOILER will be executed from a separate circuit provided with differential protection fuses of 30 mA. External connections must comply with applicable norms. Connection to the electric grid of the building must allow the entire electric insulataion of the central heating BOILER for situations when interventions are required. Grid connection is done taking into account the symbolism of colours as follows: Brown = phase, Blue = null, Green and Yellow = earthing. The current plug must be accessible so that the user can easily disconnect it.

9.2.1.3 Graphic context - Stand-by control panel LMC1112

This context is associated with an inactive/ waiting state of the central heating station. In the stand-by state all the activation elements are inactive and every burning demand is ignored. An exception to the rule: the anti-freezing function (generated by a value of water temperature in the installation lower than 9°C, which will initiate a burning cycle to prevent the freezing of the thermal agent in the installation. Entering and exiting this regine is done by pressing POWER key for at least one second. Possible actions: - POWER – comute between ON/OFF states; - LIGHT – activation or deactivation of light functions. Figure 1.15 is an example of display in the stand-by state (pressure on the thermal circuit 1,8 bar).

9.2.1.4 Graphic context – error state control panel LMC1112

The display of an error is sometimes asociated with a state of malfunctioning/ error of the station. There are three types of errors: - Critical errors: all the activating/state elements of the central heating station are inactive and any burning request is ignored. Getting out of this critical error state is done by pressing the RESET key; - Normal errors: all the activating/state elements of the central heating station are active and any burning request is ignored. Getting out of a normal error state is done by pressing the RESET key; - Informative errors: all the activating/state elements of the central heating station are active and all burning requests are accepted. Getting out of an informative state is done automatically when the cause of error disappears. In this context the diplay flashes a message with the error code. Possible actions: - RESET – reset critical or normal errors; - LIGHT - activation or deactivation of light functions – possible only if the central heating station is not in a state of critical error. Figura 1.16 is an example of display of an error (in our case E20).

9.2.1.5 Graphic context – waiting state control panel LMC1112

Waiting state is associated with a functioning state of the station, but with no burning request.

9.2.1.7 Graphic context – adjustment of functioning parameters control panel LMC1112

The adjustment of the main functions of the station (thermal temperature, hot water temperature) can be done both in the waiting state and in the functioning state. When we enter the state display of these values, the last value previously set will be displayed. Only in the period the set value is displayed we can make changes of its value. Practically, at any moment of functioning of the station, by pressing J1 (CH+) or J2 (CH-) keys, the set value of the thermal temperature will be displayed and can be changed. Similarlry, at any moment of functioning of the station, by pressing the J3 (DHW+) or J4 (DHW-) keys, the set value of the hot water temperature will be displayed and can be changed. While doing these settings, the display will show the value of the set temperature (thermal or hot water), the pressure in the installation and the functioning mode of the station (winter/ summer). Getting out of this setting mode is done automatically if no key is pressed for at least 3 seconds. Figures 1.20 and 1.21 are two examples of displaying temperature in the setting mode. Figure 1.20 – pressure in the heating installation is 1,8 bar, central heating station is set on winter mode, set value of thermal temperature is 42°C; Figure 1.21 – pressure in the heating installation 1,6 bar, central heating station is set on winter mode, set value of hot water temperature is 60°C.

The adjustment of temperature is done by pressing J5 (MENU/OK) and by pressing J1(P-) or J2(P+) until symbol S10( ) flashes. To increase/ decrease use keys "+" and "–".

9.5 Functioning as domestic hot water BOILER (DHW)

The BOILER can function as DHW in both seasons – winter and summer. The DHW request has priority over the heating request in the „winter” mode. The BOILER can function as instant DHW or as accumulation boiler DHW (the boiler is purchased separately). For the functioning of the BOILER as an accumulation boiler DHW BOILER please address an authorised service company. In intant regime, the minimum flow of hot water detected by the BOILER is 2.4 l/min. For confort in using the BOILER as a DHW BOILER we recommend to exploit the BOILER at a flow of approximately 7-8 l/min. When the BOILER functions with low flows, the BOILER functions continuously at the minimum charge as long as the hot water temperature is under the threshold limit of 63°C. When the hot water temperature reaches the mentioned limit of 63°C, the burner is closed and a new burning will happen when the hot water temperature is lower than the limit of 60°C. When the BOILER functions with high flows, the hot water temperature will be the opposite of the hot water flow, but lower than the set temperature. With instant DHW configuration on request the CONFORT function can be activated. This function allows the delivery of hot water as soon as possible, while keeping the boiler hot. If the function is active, the boiler starts when the hot water temperature is equal to the set hot water temperature; the boiler stops when the hot water temperature is 8°C ( fixed value) higher than the set hot water temperature. If the water heated in this way is not consumed within one hour, the CONFORT function is automatically deactivated. Activation/ deactivation of the function is done by pressing J5 (MENU/OK) key, press J1 (P-) or J2(P+) key until the symbol

S12( ) flashes. Press J3 (P+) or J4(P-) for activation/ deactivation.

9.5.1 Domestic hot water operation via an individual boiler connected to the boiler (see chapter 11 '' Operating modes '')

For hot water DHW operation, contact your authorized service provider, approved and trained by KOBER SRL Vaduri Branch! C13GC35; C14GC25 boilers can work with an accumulation boiler to produce domestic hot water in accumulation mode. C13GC35-CH1 and C13GC35-CH2 (boiler versions designed only for central heating preparation) can work with a hot-water tank with coil, for domestic hot water production. The boilers can work this way for both seasons ("Winter" and "Summer"). DHW heating demand by boiler is the priority of heating demand in AT mode. If the operation with a storage/preparation tank is set, DHW demand is triggered by the boiler temperature sensor. The boiler will operate in DHW mode when the water temperature in the tank drops below the value set by user. To homogenize the water temperature in the boiler, the boiler pump will continue to operate for a while (indicated by parameter SP:17) after any burning cycle. For any type of boiler, the user will set DHW temperature in the boiler. The boiler will provide hot water at 70 ° C. The user can limit hot water temperature from the boiler circuit board. In the case of continuous operation of the boiler at minimum capacity in DHW mode, the boiler water temperature might exceed the value of 70 ° C. Therefore, for safety reasons, the burner is off (the gas valve will be closed) when the boiler water temperature reaches 73 ° C (fixed value); circulation pump will continue to operate. A new ignition will take place after the water temperature drops below 70°C

REV.12.06.2017 15 din 26

In case the boiler is configured to work with boiler, the function ANTILEGIONELLA is activated automatically. This means that the boiler temperature is maintained at an elevated temperature for an hour, once every week.

9.6 Functioning as heating BOILER (HS)

The BOILER functions in this mode when „winter” season is selected. For the selection of the type of heating installation (floor or radiators) please contact an authorised service company. If a thermoregulator is connected to the electronic board, the BOILERs functions in thermal mode only when the surrounding temperature is lower than the set temperature in the thermoregulator.

9.7 Preset functions related to BOILER safety

1. Anti-freezing protection function. If the temperature in the installation drops below 9°C, the system turns on the heating at minimum charge until the temperature reaches 30°C. 2. Post-circulation of the hot water and heating pump function. The post-circulation cycle starts only if the system is not in the BURNING state. Advantages: a) it prevents the water from becoming BOILERary at high temperatures inside the heat switch. In this way, calcareous deposits are reduced significantly b) it prevents water from boiling inside the heat switch in the post-heat interval. These advantages have as result the protection of the heat switch. 3. Pump anti-blocking system and three-way valve. If the BOILER did not go through a burning cycle in the last 24h, the pump will be started for 12 seconds to avoid its blocking. In this time the three-way valve is also activated and deactivated. 4. Post-ventilation After each BOILER stop, the ventilator still functions for some time to evacuate completely the burning gases out of the BOILER and also the water vapours they contain. In this way, both the ventilator control electric circuit and the primary heat switch, which cools down partially, are protected. 5. “Legionella” bacteria prevention function This function is active for the functioning of the BOILER as accumulation boiler WHW. When hot water is prepared in the boiler, the ANTILEGIONELLA function is actived automatically. This function implies that once a week the temperature of the water in the boiler is kept at the value of 65°C. 6. Setting additional functions Setting additional functions is done only in the "Service" menu. Please contact an authorised service company.
