IMPORTANT TIPS

•Read the instruction manual before you perform the installation and operation of the boiler.

•This instruction manual is an integral equipment of the boiler. It should be kept through the whole operation life of the boiler and carefully read.

It contains all the information and warnings for safety during installation, use and maintenance to be followed.

•The boiler is complicated appliance as it contains numerous precise mechanisms.

•Reliable operation of the boiler depends mainly on appropriate performance of systems that boiler cooperates with such as:

- gas system,

- flue gas-air system,

- central heating system,

- domestic hot water system.

•Flue gas - air installation for C type boilers should be made of separately approved and introduced on the market gas - air system. Adapters

connecting the boiler with a pipe system must have a measuring points. Flue gas – air system must meet the specifications set out in section

3.8 of this manual.

•Flue gas - air system must be tight. Leaks on the connections of flue gas pipes can result in flooding of the boiler by condensate.

Manufacturer is not liable for damage and malfunction of the boiler arising out from above mentioned reason.

•Installation of the boiler should be performed only by a qualified person

. Make sure that the installer has confirmed in writing the

tightness of the gas installation had been checked after connecting the boiler to the system.

•Boiler may be installed and operated only in a room where all building works have been completed. It is not allowed to install and operate the

boiler in a room where building works are still in progress.

•The cleanliness of air in a room where the boiler will be installed must meet the same requirements as for rooms designer for people.

•There should be installed appropriate filters on a central heating system and gas system. Filters are not included in a basic boiler equipment.

•An example of connecting a boiler to these systems is presented on fig. 3.5.1.

•All defects caused by lack of filters on central heating or gas supply will not be repaired under guarantee.

•Central heating system must be thoroughly cleaned and rinsed, the procedure is described on p.3.5.2.

•To avoid malicious calcification process of flue gas - water heat exchanger and also for reduce a risk of other items damage, there should be:

- the proper water preparation in C.H. circuit according to p.3.5.2, Proper water parameters in C.H. system allows for long term operation

maintaining its high efficiency, what leads to lower costs of gas consumption,

- proper tightness of central heating system ensured by avoiding frequent refilling it with water,

•Complaints caused by gas-water heat exchanger calcification will not be repaired under guarantee.

•The initial start-up of the boiler as well as its repairs, adjustments and maintenance works must be performed only by AUTHORISED

SERVICE COMPANY.

•The boiler must be operated only by an adult.

•Do not do any repairs and modifications by yourself.

•Do not cover any ventilation grilles.

•Do not keep in the vicinity of the boiler any containers with flammable, aggressive and corrosive liquids and other similar substances.

•Any failures that are result of operation discordant to recommendations included in this instruction manual cannot be subject to warranty

claims.

•Manufacturer is not responsible for any failures being the result of faults during the process of installation and inobservance the regulations

and instructions given by the manufacturer.

•Complying with recommendations given in this instruction manual ensures a long, reliable and safe operation of the boiler.

When you smell gas:

- do not use any electrical switches that could cause any spark,

- open the door and windows,

- shut down the main gas valve,

- contact your gas supplier.

In case of any failure you should:

- disconnect the boiler from a power source,

- shut down the gas supply valve,

- cut off a water supply and drain a water from the boiler and whole central heating system as well (when there is any risk of

freezing of the system),

- drain the water from the system in any case of leakage that could cause a flood ,

- contact the nearest AUTHORISED SERVICE COMPANY or the producer.

‘Qualified person’, means the one that has all required technical qualifications in an area of doing all the works necessary to connect appliances to the

gas mains, central heating system and flue gas duct, accordingly to local regulations.

•power supply of the three-way valve (item 12, towards the central heating installation),

•power supply of the pump (item 7),

•power supply of the fan (item 5),

•followed by a sequence of ignition and the fan speed is set to ignition value (P02),

•after noticing presents of flame, fan speed is decreased to minimal value and maintained at this level for the time set by parameter (P29),

•then the controller starts the fan speed regulation taking into account a value of the central heating slope - parameter (P30). If the heating water temperature

exceeds 95°C, the burner is turned off until the ho t water temperature drops below 81°C.

The system of continuous flame modulation uses the PI control algorithm to minimize the difference between the temperature read by the NTC sensor (item 18) and the value

of the set temperature of central heating.

The boiler switches off when the room temperature control unit is signalizing reaching the desired temperature in the room or when the heating water temperature exceeds

the set point by the hysteresis value of central heating.

After turning off the boiler pump is running during the pump overrun - parameter (27). Simultaneously the time of break in operation is metered - parameter (P26).

Restart of the boiler will be done automatically under the following conditions simultaneously:

•heating water temperature is lower than the set temperature,

•break time in the central heating operation has elapsed [P26],

•room temperature control unit provides the signal "heat".

The list of controller parameters according to table 4.4.

2.4.2. Temperature regulation dependent on external temperature

After connecting to the boiler the outdoor temperature sensor and changing parameter (P33) to the value different than 0, the boiler will adjust the setting based on the

external temperature measurement. The temperature setting in the central heating circuit is calculated on the basis of the heating curve set by parameter (P33) and the

outside temperature. It is not possible to set the central heating supply temperature manually using buttons K1 and K2. The maximum heating water temperature is defined by

the parameter (P23).

The slope of the curve can be changed in the range from 0 to 30. The set of heating curves is shown on the diagram below.

After pressing the K3 button

twice, it is possible to see the

value measured by the outdoor

temperature sensor. If the

sensor is not connected,"---" will

be displayed. The values are

displayed for 5 seconds.

2.4.3. Method of D.H.W. heating in combi boilers

Combi boiler heats the water in a instantaneous way. Water temperature is set using the buttons K6 and K7 in the range from 30oC to 60oC. The water temperature at the

outlet depends on water temperature at the inlet.

In this mode the water heating demand occurs when the flow sensor turns on at the value above 2,7 l/min (ends at a flow <2,3 l/min.)

Then follows the sequence:

•switching the power of the three way valve (item 12) in direction of the water-water heat exchanger, supply for the pump (item 7),

•the temperature of domestic hot water NTC sensor is read (item 27) and is compared with the set value. If it is less than the domestic hot water setting a

sequence of ignition follows,

•after detection of flame and finish of starting sequence the controller starts regulation of fan speed according to the temperature set. If the heating water

temperature exceeds 90°C the burner is turned off u ntil the hot water temperature drops below 81°C

Continuous flame modulation system uses PID control algorithm to minimize the difference between the value of temperature reading by the NTC sensor, and the domestic

hot water setpoint. If during the heating of domestic water its temperature exceeds the setting by the hysteresis value of DHW then burner is turned off until the water

temperature drops to the setpoint.

Central heating hot water flows through the water-water heat exchanger segments and heats the water. The heated water is directed to the point of its collection.

Fig. 2.4.3.1. Diagram of domestic water

temperature at the boiler outlet at

thermal power of 50kW depending on

the water flow rate.

2.4.4. The way of heating the water in system boilers cooperating with domestic water tank.

The boiler may cooperate with all domestic water tanks available in Termet`s offer. Adjustment and display of domestic water temperature are done on the controller of the

boiler. Boilers are factory designed for cooperation with domestic hot water tank.

The process of heating the domestic water is as follows:

When the water temperature sensor finds the temperature lower than set on the control panel with buttons K6 and K7, then the process of pumping the water to the central

heating system will be stopped and the heating water temperature will be controlled in an optimal way by the controller of the boiler.

Heating the domestic water with cooperation of boiler and domestic hot water tank is as follows:

•water temperature sensor in the tank indicates the water temperature drop below the set temperature by the hysteresis value - 3°C, eg due to opening of inlet

tap valve;

•boiler’s controller makes the three-way valve to draw the heating water to a short circuit while giving a signal to the spark generator and gas valve;

•heating water flows through the coil of tank (short circuit);

•controller of the boiler controls the heating water temperature in an optimal way so as not to exceed a permissible value. If the heating water temperature

exceeds 90°C, the burner is turned off until the ho t water temperature drops below 81°C;

•after achieving the set water temperature in the tank increased by the hysteresis value - 4°C, boiler ’s controller gets distorted the three-way valve for long circuit

and at fulfillment of the following conditions the heating water is pumped into the central heating system:

- heating water temperature is lower than the set temperature

- room thermostat gives a signal “heat”.

Hot water temperature at the point of consumption may differ from the set value, and therefore it is advisable to install a mixing valve for domestic hot water

systems.

Note: When using a water tank in the ECOCONDENS CRYSTAL PLUS-50 boiler , to ensure proper operation of the boiler the required coil power in the tank is

minimum 15kW.

2.4.5. Anti-legionella function

In order to combat the legionella bacteria in the DHW tank, the boiler switches on every 7 days by default during the periods defined by parameter (P12) and heats the

domestic hot water in the tank to the value defined by parameter (P11): 60°C by default. The function is activated only when parameter (P00) is set to 3 or 4. To prevent

excessive energy consumption, the timing function is reset when the temperature specified by parameter (P11) is reached during normal use.

3.5.1. System cleaning and water treatment for the C.H. filling.

Every component of C.H. system is threatened by limestone deposits, corrosion and other dangerous processes. Boiler is the most expensive part of C.H. system and it is

necessary to protect its components like heat exchanger and other parts against harmful processes. Correct C.H. circuit preparation for using relies on making two

operations: cleaning the CH system and treating the water that fills the system.

System cleaning

In new installation it is possible to find some remains of industrial process soldering and welding remains, flux, oil and grease residue among others. Older installations

usually have products of corrosion in them. It necessary to clean up the systems with a water to remove the remains before boiler is mounted. Afterwards, system should be

cleaned with appropriate chemicals- for example BM3 Cleaner from BoilerMag. After that it is necessary to rinse the installation with water.

Water treatment to fill the system

For filling the system, it is recommended to use water with parameters: pH 6,5- 8,5, hardness < 10 °n (~ 18°F). Do not use demineralised or destilled water. To ensure

protection against rocks despositing, corrosion, it is recommended to use a special inhibitor, for example BM1 Protector from BoilerMag.. Antifreeze liquid can also be used,

for example BM Zero Antifreeze from BoilerMag.

Low-temperature circuits

In the low-temperature area, it is recommended to treat the water by using BM7 Biocide.

Filtration technique

Additionally, in order to ensure the quality of operation heating system, it is recommended to mount a modern filters, which works on the principle of the magnetic and cyclone

effect from BoilerMag.

Notice:

- method and amount of use specific products for system cleaning and water treatment should be in accordance to the product manufacturer's instruction.

- above steps should be made by the authorized installer or service technician.

3.6. Connection of the boiler to a domestic hot water system

3.8.7 Examples of air-flue gas systems installations.

ECOCONDENS Crystal Plus 50 boilers could be installed as B-type appliances (where air needed for

combustion is taken from the room where boiler is installed) or as C-type appliances (where air needed

for combustion is taken from outside). C-type appliances could be divided as follows:

- C13 – flue-gas system through the wall. Air for combustion is taken from the outside (for 20kW boilers)

- C33 – flue-gas outlet and air inlet through the roof

- C43 – flue-gas outlet connected to chimney. Air for combustion taken from outside of the building.

- C63 – flue-gas outlet through the wall to the outside of the building. Air for combustion taken from

chimney shaft.

- B23 – air for combustion is taken from inside the toom where boiler is installed. Flue-gas is taken outside

through the chimney shaft,.

Depending on local regulations some types of installations might not be allowed. Always consult your

local regulations before making flue-gas system project.

Before turning on the boiler check if flue-gas system is made according to the project and air- and flue

ducts lengths are shorter than maximum lengths showed in tables 3.8... Make sure flue-gas system is

tight.

After turning on the boiler check if it operates correctly. Also check combustion parameters by checking

concentration of CO2and/or O2in flue-gas.

Boiler is equipped with a non-return flap, which protects against reverse flow of flue gas. The use of a non-

return flap enables for connection of many boilers to the collective chimney system.
