1. The installation, lighting of the test fire and training of the operators shall be performed by an installation company trained by the manufacturer, which shall also fill in the boiler installation

record (page 36).

2. When using pellets for heating only use high-quality fuel with the diameter of 6 - 8 mm, made of soft wood without bark and contaminants (white pellets).

3. During fuel combustion substances are produced that may damage the boiler body. Therefore, the boiler must be equipped with Laddomat 22 or a thermo-regulation valve to maintain the minimum temperature of return water to the boiler of 65 °C.

The operation temperature of the water in the boiler must be in the range of 80 - 90 °C.

4. Each circulation pump in the system must be controlled by a thermostat so that the minimum

temperature of return water can be guaranteed.

5. We recommend you to use the boiler in a system with one equalizing tank the volume of which should be 500 - 100 l to achieve a higher service life of the pellet burner and lower fuel consumption.

CAUTION - If the boiler is equipped with Laddomat 22 or a hot-water thermo-

regulation valve TV 60 °C (65/70/72/77 °C) and an equalizing tank (see the attached diagrams), the boiler body is subject to an extended guarantee of 36 months instead

of24months.Theguaranteeperiodoftheotherpartsremainsunchanged.If these

principles are not observed, the service life of the boiler body may be considerably reduced due to low-temperature corrosion.

1. Application

ATMOS D15PX and D20PX hot-water boilers are designed for convenient heating of family houses, holiday homes and other buildings with pellets. Their compact solution enables installation in small boiler rooms. For the heating you can use high-quality wooden pellets with the diameter of 6 to 8 mm. The

boiler is not intended for burning of wood, sawdust and minor wood waste.

2. Technical description

Boilers D15PX and D20PX are supplied as a complete plant with a built-in conveyor, pellet reservoir with the volume of 175 l and ATMOS A25 pellet burner. They are designed for electronically controlled burning of pellets with automatic ignition of fuel. The pellet burner is incorporated into the front part of the boiler in the door of the lower combustion chamber. This chamber is also used as an area for ash. The boiler body is made as a weldment of steel sheets with the thickness of 3 - 6 mm. It consists of the combustion chamber with ceramic shaped bricks for ideal flame burn out with high efficiency. A tube exchanger with a segmental decelerators with function of rough (operation) cleaning without necessity of taking them out is placed in the back part of the boiler. The boiler body is insulated from the outside with mineral felt located under the sheet-metal covers of the outer boiler jacket. A fuel reservoir from which the pellets are transported to the burner with a screw conveyor is located in the top part. Fuel metering is controlled fully automatically. In the fron part of the boiler there is a panel with the main switch, the switch of the pellet burner (L2), an operation (control) thermostat, a safety thermostat, a thermometer and a 6.3 A fuse. The boiler is not equipped with a cooling loop against overheating as thanks to the small quantity of fuel in the burner there is no risk of boiler overheating in case of a power supply failure. Boilers DxxPX is equiped with exhaust fan.

8. Chimney

A boiler with a burner must always be connected to the chimney vent with consent of the responsible chimney maintenance company. The chimney vent must always produce sufficient

draught and exhaust flue gas to the free atmosphere in virtually all operation conditions. For proper function of boiler the separate chimney vent must be properly dimensioned as the combustion, output and service life of the boiler depends on its draught. The draught of a boiler directly depends on its cross-section, height and roughness of the inner wall. No other device may be connected to the chimney to which a boiler is connected. The diameter of the chimney must not be smaller than the outlet on the boiler (min. 150 mm). The chimney draught must achieve prescribed values (see the technical specifications in the boiler manual). However, the boiler must not be excessively high so as not to reduce the efficiency of the boiler and not to disturb its combustion (tear the flame). In case of too strong draught install a throttling flap or draught reducer in the flue gas duct between the boiler and the chimney.

Guideline values of dimensions of the chimney cross-section: 20 x 20 cm height 7 m Ø 20 cm height 8 m 15x15cm height 11 m Ø 16 cm height 12 m

The exact determination of chimney dimensions is defined by the ČSN 73 4201 standard.

The prescribed chimney draught is specified in the “Technical data” chapter of the manual of the particular boiler.

9. Flue gas duct of the boiler

The flue gas duct from the boiler must lead to the chimney vent. If the boiler cannot be connected directly to

EN

the chimney vent, the corresponding flue gas duct adapter must be as short as possible with regard to the particular conditions, but not longer than 1 m, without additional heating surface and it must rise towards the chimney. Flue gas ducts must be mechanically strong and leak-proof for flue gas and cleanable inside. Flue gas ducts must not lead through other owners‘ residential or commercial units. The inner cross-section of the flue gas duct must not be larger than the inner cross-section of the smoke uptake and must not get narrower towards the chimney. The use of smoke elbows is not suitable. Designs of passages of flue gas ducts through structures of flammable materials are defined in

Annexes 2 and 3 of ČSN 061008 and are mainly suitable for

mobile units, wooden huts, etc.

10. Fire protection within the installation and use of heat appliances

Extract from ČSN 061008 - Fire safety of local appliances and sources of heat

Safe distances

On installation of an appliance the safe distance from building materials must be maintained, at least 200 mm. This distance is valid for boilers and flue gas ducts located near flammable materials of the B, C1 and C2 flammability class (the flammability class is specified in tab. no. 1). The safety distance (200 mm) must be doubled if boilers and flue gas ducts are located near flammable materials of the C3 class (see tab. no.1). The safety distance must be doubled if the flammability class of flammable material is not evidenced. The safety distance may be reduced to a half (100 mm) if you use a nonflammable heat insulating panel (asbestos panel) with the thickness of at least 5 mm, located 25 mm from the protected flammable material (flammable insulation). A shielding panel or protective screen (on the protected object) must exceed the outline of the boilers (incl. flue gas ducts) at each side by at least 150 mm and the top surface of the boiler by at least 300 mm. A shielding panel or protective screen must also be used to protect fixtures of flammable materials if the safe distance cannot be

maintained (e.g. in mobile units, huts, etc. - more details in ČSN 061008). The safety distance must

also be maintained in case of installation of fixtures near boilers.

www.atmos.cz

Operation manual - EN

If boilers are located on a floor of flammable materials, they must be installed on a non-flammable, heat-insulating pad, exceeding the ground plan at the side of the feeding and ashpan opening by at least 300 mm before the opening - at the other sides by at least 100 mm. As non-flammable, heat insulation pads you can use all materials of the A flammability class.

16. Selection and method of connection of control and heating-

system elements

The boilers are delivered to the user with the basic control of the boiler output, which complies with the requirements for the heating comfort and safety. The control ensures the required output temperature of the boiler water (80 - 90 °C). Boilers are equipped with connector for connection of the pump in the boiler circuit and functions for its control directly from the regulation of the ATMOS A25 burner or together through the thermostat of the pump TP 70 °C (connected in series - from serial production). The connection of these elements is indicated in the electric wiring diagram. Each pump in the system must be controlled with a separate thermostat to avoid cooling of the boiler at the return line below 65 °C. If the boiler is installed without a storage or equalizing tank, the pump in the circuit of the heated building must be controlled by a separate thermostat or electronic control unit to only run when the pump in the boiler circuit is running. Therefore switch the pump in the circuit of the heated building if the boiler temperature is higher than 80 °C. If there is very good spontaneous (gravity) circulation of water between the boiler and the system, which increase the time necessary for the boiler to reach the required temperature, we can disconnect

TČ70 °C pump thermostat and decrease switching temperature for the pump in boiler circuit to a lower

temperature (Parameter S37). The required water temperature for the building is always set with the use of a three-way mixing valve. The mixing valve may be controlled manually or with an electronic control unit, which will contribute to more comfortable and more economical operation of the heating system. The way of

connection of all the elements is always determined by the designer in accordance with the specific

18 - EN

www.atmos.cz

Operation manual - EN

conditions of the heating system. The electric installation related to the sufficient equipment of the boilers with the above mentioned elements must be implemented by a qualified person in accordance

with valid ČSN EN standard. If you install the ACD01, ACD03/04 electronic control unit, follow the

instructions in the operation manual of this unit. Connect this control unit in the boiler in accordance with the electric wiring diagram in this manual. NeverswitchofftheACD01,ACD03/04electronic

control unit outside the heating season (with the main switch on the boiler)!

When connecting the boiler with the equalizing (accumulation) reservoir, the boiler is controlled best according two TS and TV sensors located on the tank. Switching of pumps in the system circuit in this case does not depend on the boiler temperature and therefore it is solved according to potential requirements of the system.

For the installation of the boiler can be use an open expansion vessel; however, it may

alsobeclosedifpermittedbythelegislationoftheparticularcountry.Youmustinstall

the boiler in such a way to avoid its overheating and consequent damage even in case of a power supply failure.

During the installation support the back part of the boiler to raise it by 10 mm to facilitate its rinsing and bleeding.

For the control of the heating system we recommend the following controllers:

a) ATMOS ACD 03 / 04 - Eqvithermal controller for solid fuel boilers b) ATMOS ACD 01 - Eqvithermal controller set for solid fuel boilers c) KOMEXTHERM, Praha tel.: +420 235 313 284 d) KTR, Uherský Brod tel.: +420 572 633 985

17. Protection of the boiler from corrosion

The prescribed solution consists in the installation of the boiler with Laddomat 22, or a thermoregulation valve, which allows you to create a separated boiler and heating (primary and secondary) circuit to ensure the minimum temperature of return water to the boiler of 65 °C. The higher the return water temperature is, the lower you will keep condensation of tar and acids that are harmful for the boiler body. The output water temperature of the boiler must be permanently in the range of 80 - 90 °C. Another variant is connection of the boiler with a three-way mixing valve with an actuator controlled from the electronic controler (e.g., ATMOS ACD01, ACD03, ACD04) to keep minimum temperature of the water returning to the boiler (65 - 75 °C). The flue gas temperature must not drop below 110 °C during normal operation. A low flue gas temperature causes condensation of tar and acids even though the output water temperature (80 - 90 °C) and the return water temperature (65 °C) is maintained. These situations may occur e.g. in case of a wrong setting of the pellet burner (low output - ALARM SETTINGS).

The D15PX and D20PX boilers are equipped with a function for the control of flue-gas temperature. In case of bad adjustment of the output (too low), the boiler is shutdown and alarm is activated – ALARMSETTINGS.

CAUTION - We recommend you to always use the D15PX, D20PX boilers in

21. Thermoregulatory valve

Thermoregulatory valve type, TV 60 °C (65/70/72/77 °C) is used with solid fuel boilers. When the boiler water temperature reaches + 60 °C (65 °C) , the thermoregulatory valve opens and fluid from the building heating circuit (2) enters the boiler circuit (3 →1). Inlets 1 and 3 always remain open. This ensures that the minimum temperature of the water returning to the boiler is maintained. If need be, a thermoregulatory valve set to a higher temperature (E.g. 70/72/77 °C) may be used.

22. Operation instructions

Preparation of boilers for the operation

EN

Before putting the boiler in operation you must make sure that the system is filled with water and bled. You must always operate the boiler in accordance with the instructions contained in this manual to achieve high quality and safety of the functionality of the boiler. The boiler may only be operated by adult persons. The commissioning of the boiler must be done in accordance with this manual and the operation manuals attached to the pellets burner by a qualified person. Before igniting pellets perform several operations. Check all the lids and doors for proper closing. Check whether the burner is properly tightened to the boiler over the gasket and that the end switch stop is in its place. Also, check the hose between the burner and the conveyor for proper tensioning and such inclination that allows free falling of pellets to the burner (pipe lenght - 550 mm). They must not accumulate in the hose! Pellets can be pumped to the conveyor by inserting the supply cable of the conveyor into a normal socket 230V/50Hz. When the pellets begin to fall out of the conveyor, insert the cable back into the socket on the burner and proceed to the control itself. This pumping is performed with a new boiler only. During normal operation, after a situation when there are no pellets in the reservoir, only switch off and on the main switch on the boiler board. IfeverythingisOK,switch on the main switch (red) and the pellet burner switch (black) and this way the boiler is put into operation. After automatic ignition of the burner, flaring up and achieving the required output (about 30 - 40 min), perform adjustment of the boiler. Adjust combustion of the burner (boiler) with the use of a flue gas analyzer in the measurement place (opening) in the flue between the boiler and the chimney. Always adjust the burner in a stabilized condition, approx. 20 - 30 minutes after fuel ignition. If there is no flue gas analyzer available for the boiler adjustment at the moment, you can adjust the pellet burner „roughly by guesswork“. Set the quantity of fuel and combustion air in such a way to stop the flame 10 cm before the opposite ceramic screen (the flame should not touch the wall). However, the flames must not turn at the opposite wall. In such a way add combustion air (open the fan flap) or reduce the fuel supply T4 and T6)

.

(burner parameters

CAUTION- This adjustment does not replace adjustment made with the use of a flue gas analyzer by a qualified person. Changes of settings of the boiler and burner may only be performed by a

person that is qualified in accordance with all the valid regulations, ČSN and EN standards.

23. Procedure for optimal adjustment of the boiler for wood pellets

In order to maximise the results of measurements of emissions and energy efficiency of ATMOS boilers, the following main conditions must be met:

Fuel:

Type of pellets: wood pellets, Ø 6 - 8 mm, length 5 - 25 mm Quality of pellets: white pellets with minimum ash content, low content of dust, non-agglomerating, without crust

The chimney draught: must be in agreement with the instructions for use.

D15PX 15 Pa (0,15 mbar) D20PX 16 Pa (0,16 mbar)

There must not be great changes in the chimney draught during operation and measurement of the boiler. (e.g., due to wind) Maximum ± 2 Pa (0.02 mbar)

www.atmos.cz

EN - 23

Operation manual - EN

Boiler firing up:

Prior to commissioning of the boiler (making fire) check whether the burner, boiler, flue-gas ducting and chimney are properly clean. Check all lids, doors, hose between the conveyor and burner and the burner itself that it is properly fixed and tightened to the boiler.

EN

Any hole or leakage would distort the measured energy efficiency of the boiler and quality of combustion. Perform commissioning of the boiler.

Measurement of emissions: with flue-gas analyser

Measurement point: 300 to 500 mm behind the boiler output Time of measurement: perform measurement and combustion adjustment in the steady state about 30 to 40 minutes from ignition of fuel.

ATTENTION – the measurement should be performed at least 10 minutes after the time defined by the parameter T10 – gradual start of the burner to the normal output (set by manufacturer to T10 = 10 to 20 minutes after ignition). The burner output is defined by T4 and T6 parameters

ParametrТ4– time of operation of the screw conveyor after standstill period ParametrТ6– standstill time of the screw conveyor after operation period

The recommended default setting is available in the instructions for use of the burner for a specific output.

The general rule, however, is that in practice the burner output is set by 30% lower than heat losses of the object. In fact, the pellet burner is a hard source of energy. The exception are only

systems with a high volume of water or old stone objects where we set the burner output equal to heat losses of the object.

The fuel amount and the amount of combustion air must be adjusted so that the flame ends (10 cm) before the rear ceramic screen of the boiler – (the flame must not lick the wall). Under no circumstances should the flames turn over on the opposite wall. If it happens, it is necessary to add combustion air by opening the flap on the burner fan or to decrease fuel dosage – see the instructions for use of the ATMOS burner. If the flame is, however, too short, the flap on the burner fan must be partly closed or revolutions of the burner fan must be decreased (S3 parameter). But do not lower the S3 parameter below 60 %.

Recommended values of O2 in combustion products according to the boiler type:

The excess of oxygen (O2) in combustion products is adjusted so that it is in the range from (7) 8 to 9 (10)% at average CO < 250 mg/m3 at O2ref=10(13)%.This adjustment is optimal for

common practice when the customer combusts various types of pellets with a certain tolerance of caloric value. During an authorized measurement of combustion quality performed by chimney sweeper it is recommended to set the excess of oxygen in combustion products to the minimum value. This is a general principle that the lower the excess of oxygen in combustion products the better are the

resulting recalculated values of the measurement.

EN

As for the dust measurement in combustion products (dust), the principles are the same as for CO measurement. However, it is necessary to know that precise measurement of the dust is based on

regular cleaning of the measuring instrument immediately after measurement and preferably also before the following measurement. Unsufficient cleaning is a frequent problem of these instruments!

The boiler room with the D15PX or D20PX boiler with the pneumatic pellet feeder ATMOS APS 250 SPX (connected directly to the boiler) in combination with multipoint sucking of pellets from a big pellet reservoir (silo). Two circuit changer enable to swap (change) between two pneumatic probes placed in the big pellet silo. The pneumatic feeder serves for automatic feeding of boiler tank from the big external pellet silo which is placed inside or outside the building.

This system uses pellets diameter 5 - 10 mm from outside silo. Can be in max. distance of 15 m (pipe lenght 2x 15 m) with the elevation max. 6 m.

EN

Designed for boilers with output range from 5 to 80 kW. Power consumption of the pneumatic feeder is 1590 W. The device is not running continuously but only when the pellet reservoir in the boiler is empty.

CAUTION - If pellets are drawn to the storage in the boiler plant directly from the cistern, several principles must be observed that prevent their crushing during pneumatic transport. First of all you must make sure that they do not hit the hard wall of the storage, but a screen that is suspended in the centre of the storage from the ceiling. This way you will ensure even filling of the storage and prevent crushing into small pellets and dust. Ask the pellet

suppliers about further possibilities and conditions of pellet drawing.

28. Refuelling

The boiler is equipped with an integrated fuel tank that must be refilled in the interval from 1 to 3 days.

EN

If the alarm message ALARMPELLETS-REFILLPELLETS appears on the burner display, pellets must be added to the fuel tank. Open the tank cover in the top part of the boiler and add pellets. Switch off and on the main switch (red) on the boiler board to remove alarm and restart the boiler. When the pellets are added, it is not necessary to pump the pellets to the conveyor! The boiler is equipped with a special function against its full emptying.

In the case that the refuelling interval is too short for your needs, an attachment with the height of 200 mm (65 l) or 300 mm (95 l) can be added (to buy) to the tank of the boiler. It is, however, necessary to buy additional step ladder for convenient refuelling according to all valid safety regulations. However, additional buying of the pneumatic pellet feeder ATMOS APS 250 SPX for convenient automatic refuelling from any silo, e.g., for the whole season (textile silo, separate room), is the ideal solution.

The D15PX and D20PX boilers are equipped with a function for the control of flue-gas temperature. In case of bad adjustment of the output (too low), the boiler is shutdown and alarm is activated – ALARM SETTINGS.

Example of standard refuelling with pellets from 15 kg bags. Protection grill never take out of the boiler.

Example of the boiler with the pneumatic pellet feeder ATMOS APS 250 SPX

29. Cleaning of the boilers and ash removal

The burner and the boiler must be cleaned regularly and thoroughly once every 1 to 14 days depending on the quality of pellets and the output setting. Fly-ash and dirt accumulated in the combustion chamber of the burner and boiler considerably reduce the service life and output. Do the regular cleaning of the boiler in such a way that you first let the burner burn out (turn off the

28 - EN

www.atmos.cz

Operation manual - EN

burner switch (black) /18/). Open the cleaning door and clean the combustion chamber of the burner including the air openings in the chamber with the provided poker. If the combustion chamber of the burner is heavily soiled, remove it for cleaning and knock it out. Remove the ash from the whole cleaning chamber with the half-round ash pan (accessory of the boiler). Insert the ash pan into the boiler to the end, push the ash into the ashtray by thrusting it into the rear wall and remove the ashtray. Never leave the ash pan in the boiler! Use the handle on the cleaning lid in the rear part of the boiler hidden under the cover for operation cleaning of the tube exchanger and decelerators. By repeated pulling out and releasing of the handle the ash is knocked out from the decelerators and the tube plate walls are scraped off. To thoroughly clean the tube exchanger, firstly remove the decelerators from the tube plate together with the lid and clean it with the provided brush. Also, do not forget to clean the back smoke channel and scrape the walls of the combustion chamber of the boiler with the provided poker or brush. Put everything in the original condition after the cleaning. The ash removal from the lower chamber is always performed after operation cleaning of the tube exchanger since the dust falls to the lower chamber when cleaning the tube plate so there are no other cleaning opening necessary in the boiler! The interval of the cleaning and ash removal depends on the fuel quality, heating intensity, chimney draught and other circumstances, and it must be observed therefore.

EN

At least once a year clean (sweep) the rotating wheel of the draught fan and remove the pellet burner and clean it completely – see the instructions for use of the burner.

NOTE – Regular and thorough cleaning is important to ensure continuous output and service life of the boiler. If insufficiently cleaned, the boiler and the burner can be damages – and the guarantee will expire.

INFO – The pellet burner ATMOS A25 can be equipped with pneumatic cleaning of the combustion chamber. It will be appreciated especially by those using lower quality pellets forming certain agglomerates. See accessories for ATMOS boilers.

30. Maintenance of the heating system, including boilers

At least once every 2 weeks check or replenish water in the heating system. If the boilers are out of operation in winter, there is a danger of water freezing in the system and therefore you had better drain water from the system or fill it with an antifreeze mixture. Otherwise, only drain water in inevitable cases and for the shortest possible time. After the end of the heating season thoroughly clean the boiler and replace the damaged parts. Do not wait with the replacement of parts until the

last moment; prepare the boiler for the heating system in spring already.

31. Operation and supervision

Boiler operators must always follow the operation and maintenance instructions. Interventions into boilers that could endanger the health of the operators or other persons in the vicinity are prohibited. Boilers may only be operated by a person that is more than 18 years old, that has been acquainted with the instructions and operation of the equipment and that complies with the requirements of § 14 of the Directive no. 24/1984 Coll. The boiler operation needed increased attention to safety in terms of potential burns from hot boiler parts and systems. You must never leave unattended children near boiler that is in operation. During the operation of solid fuel boilers it is prohibited to use any flammable liquids for lighting the fire and it is also prohibited to increase the nominal output of the boiler during operation (overheating). Youmustnotputflammableobjectsontheboilerandnear

the fuel feeding and ash pan openings and ash must be stored in non-flammable containers with a lid. When handling fuel and ash, wear protective equipment (gloves, dust mask). Boilers in

operation must be under occasional supervision of the operator. The user may only carry out repair consisting in simple replacement of a spare part (e.g. a sealing cord, etc.). During the operation check the doors and cleaning openings for tightness and always tighten them properly. The user must not alter the structure and electric installation of boilers. The boiler must always be cleaned properly and in time so that free passage of all the ways can be guaranteed. Cleaning doors must always be properly closed.

Replacing the door sealing cord

Procedure: Use a screwdriver to remove the old cord and clean the groove where it was seated. Use a hammer to slightly shape the cord from the square cross-section to the trapezoidal cross-section. Grip the cord and impress it along the perimeter of the door (with the narrower base to the groove) to make it sit in the groove (you can use a small hammer as an auxiliary tool). Grip the door decorative nut in the open position and then repeatedly slowly slam the door until the cord is pressed in the groove and the door can be closed. Finally, adjust the position of the wheel where the cam of the closure gets engaged. Only using this procedure you can guarantee tightness of the door!

Adjusting the door hinges and closures

Cleaning doors are firmly connected to the boiler body with a set of two hinges. A hinge consists of a nut that is welded to the boiler body and an adjustment crew to which the door is fixed with a pin. If you want to change the setting of the hinges, first release and lift the top hood (control panel),

EN

knock both the pins out, remove the door and turn the adjusting screw (hinge) with the right thread as necessary. Put everything in the original condition in the reverse order. The door closure consists of a lever with a decorative nut and a cam that engages to a wheel that is screwed to the boiler and secured with a nut preventing its turning. After a certain time the sealing cord in the door gets compressed and therefore the wheel should be screwed deeper into the boiler. So release the nut on the wheel and screw it into the boiler in such a way that the handle can indicate 20 minutes on an imaginary clock dial after firm closing of the door. Finally, tighten the nut.

34. Environment protection

ATMOS gasification boilers comply with the most stringent environmental requirements. The boilers are certified in accordance with the EN 303-5 European Standard and belong to class 5.

Disposal of the boiler after the end of its service life

You must ensure ENVIRONMENT-FRIENDLY disposal of individual parts of the boiler. Properly remove fly-ash from the boiler before its disposal and put it in a dustbin. Scrap the boiler body and the hoods. Ceramic parts and insulation - discard to a legal dumping site.

NOTE - To ensure environment-friendly heating you must not burn any other fuel or substances in the boiler than specified. This is mainly the case of plastic bags, various types of plastic materials, paint, textiles, glass fibre as well as sawdust, sludge, vegetable (biological) pellets, dust coal.

The guarantee claim is justified only in cases where the boiler installation was carried out by a person trained by the manufacturer and in compliance with valid standards and the instruction manual. A necessary condition for justifying a guarantee claim is possession of a legible and complete record identifying the company who installed the boiler. If the installation was not carried out in a professional manner, the subsequent costs are borne by the company that carried out the installation.

6. The purchaser was familiarised with the use and operation of the product – in a provable way.

7. A claim to provide an after-guarantee period repair shall be made by the customer at the service company, too. In this case, the customer bears the repair costs.

8. The user is obliged to adhere to instructions from the operation and maintenance manual. If the operation and maintenance manual is not adhered to, in cases of negligent or unprofessional handling, or burning prohibited substances, the guarantee expires and the repair costs are borne by the customer.

9. Boiler installation and operation must be in compliance with the instruction manual where the outgoing water temperature is in the 80 - 90 °C range and the temperature of water returning to boiler at least 65 °C in all its operation modes.
