3 Description 3.1 Boiler Construction

The main part of the boiler is cast iron sectional boiler drum made of grey cast iron according to EN 1561, quality 150. Pressure parts of boiler correspond to strength requirements according to EN 303-5. The boiler drum is assembled of sections by means of pressed boiler inserts with 56 mm diameter and secured by anchor bolts. Sections create the feed space, combustion and ash space, water space and convective part of the boiler. Input and output of heating water is located in the rear of the boiler. Rear boiler section has the smoke adapter and heating water flange at its top, and the return water flange at the bottom. The stoking and ash door are mounted to the front section. Inclined grate is placed to the filling space. The whole boiler drum is insulated by using a harmless mineral insulation which reduces losses by sharing heat into the surroundings. The high-quality komaxit spray is used for boiler shell colour treatment.

3.2 Regulation and safety elements

Smoke flap of the smoke adapter regulates the output volume of flue gas from the boiler to the chimney. It is controlled by the handle with a rod in the upper left part of the boiler next to the stoking door. Stoking door choker regulates the supply of primary combustion air above the fuel. It is operated by the draught regulator or manually by the setting screw of the choker. The ash door choker regulates the supply of secondary combustion air under the boiler grate. It is operated manually by the setting screw of the choker. For the tertiary air inlet, the choker in the lower rear part of the boiler is used. It is controlled by the handle with a rod in the upper right part of the boiler. For detecting the heating water temperature and water pressure in the heating system, the associated device - thermomanometer is used. Thermomanometer sensor well is located in the upper part of the front boiler section.

3.3 Device for removing excess heat

After-cooling loop or two-way safety valve DBV 1 - 02 serve to remove excess heat in the event that th e water temperature in the boiler exceeds 95 °C. Afte r-cooling loop is connected to the flange of the bo iler according to Fig. 7, two-way safety valve according to Fig. 9). In case of the boiler overheating (outlet water temperature is higher than 95 °C), thermostatic valve switches and the excess heat is removed by the after-cooling loop.

Fig. №. 7 Hydraulic diagram of after- cooling loop connec tion

If the system is equipped with the two-way safety valve DBV 1 - 02 and the boiler becomes overheated (outlet water temperature is higher than 95 ° C), the two-way safety valve creates cold water circuit until the time the temperature drops below the limit temperature. At this moment, the discharge cooling equipment and the cold water inlet for the system refilling are simultaneously closed.

Fig. №. 8 Two way safety valve DBV 1 - 02 In the system, it is necessary to install a safety valve with max. overpressure of 400 kPa (4 bar), wh ich dimensions must correspond to the boiler nominal ou tput. The safety valve must be installed immediatel y behind the boiler. Shut-off valve must be installed between the safety valve and the boiler. For furth er questions please contact our contractual installati on companies and service organizations. Specifications of the two-way safety valve DBV 1 - 02 (from Regulus)

Opening temperature (limit): 100 °C (+0° - 5 °C) Maximum temperature: 120 °C Maximum pressure on the boiler side: 400 kPa (4 bar) The maximum pressure on the water side: 600 kPa (6 bar) Nominal flow at �p 100 kPa (1 bar): 1.9 m3/h Use

Two-way safety valve DBV 1 - 02 is designed for central heating boilers protection against overheating. In the valve drum, the discharge and refill valves are controlled by thermostatic element. When achieving the limit temperature the discharge and refill valve open simultaneously, which means that cold water flows into the boiler while hot water is drained from the boiler. When the temperature drops below the limit, the discharge and filling valves are closed simultaneously. ATTENTION! Do not replace the safety valve. In case of reaction of the two-way safety valve, wh en there could be refilled water that does not conf orm to CSN 07 7401, it is necessary to adjust water in the system so that it again conforms to this standard.

Installation

Installation may only be performed by a qualified person. For proper operation of the thermostatic two-way safety valve it is necessary to comply with the prescribed conditions for its installation and respect the flow directions indicated on its body. The safety valve is always mounted in the output pipe of the boiler or directly on the boiler in its upper part where the heated water leaves boiler and is transported into the heating system. When installing the valve, it is necessary to check whether the use of the 3/4“ socket, which can be both in the pipeline and on the boiler, ensures complete immersion of the valve thermostatic element after the valve installation. After mounting into the socket, at the point "C" (Fig. 8), the discharge pipe is connected through which the hot water from the boiler will flow to drain. At the point "A" (Fig. 8), the supply of cooling water is connected (Fig. 9), which ensures cooling the boiler down after the valve putting into operation. At the cooling water inlet, a filter to remove mechanical impurities must be installed. At the point "B" (Fig. 8) there is connected the pipeline, which according to Fig. 9 leads to the return line of the heating system near the boiler. Regular maintenance

1x per year, turn the safety valve head to remove possible contaminants seated in it. Clean the filter at the cooling water inlet. In case of using an open expansion tank, the safety device against overheating is not necessary. Every heat source in an open heating system must be connected with the open expansion tank positioned located at the highest point of the heating system. The expansion tanks must be designed to accommodate changes in water volume resulting from heating and cooling. The open expansion tanks must be equipped with non-closable vent and overflow pipes. The overflow pipe must be designed to safely drain the maximum flow volume entering the system. This can be achieved by rating the overflow pipes by one DN higher than the filling pipe. The expansion tanks and their connecting pipes must be designed and positioned so as to reliably prevent them from freezing.

Fig. №. 10 Examples of the open expansion tanks connectio n

3.4 Equipment for heat exhausting – accumulating re servoir

The boiler has to be operated with an accumulating reservoir.

Calculation of the smallest capacity of the accumulating heat exchanger,

Vsp = 15Tb x QN (1-0,3 x (QH/Qmin)) where: Vsp accumulating reservoir capacity in liters QN nominal heat power in kW Tb combustion time in hours

QH buildings’ heat load in kW Qmin smallest heat power in kW

The sizes of the accumulating reservoir have to be determined on the basis of the boiler power and the used fuel. The biggest capacity has to taken into consideration, whereas the minimum used capacity of the reservoir has to be 300 l.

In case that the reservoir is fully charged, it is necessary to shut down the boiler and heat up by heat from the accumulating reservoir. After the heat is spent in the reservoir, put the boiler into operation again. The accumulating reservoir enables provision of heat comfort and at the same time the boiler operation.

ATTENTION! Failure of it will cause extreme polluti on of the boiler drum.

Hydraulic schemes of the boilers with an accumulating reservoir are at disposal in the project materials of Viadrus at www.viadrus.cz.

5.2.5 Cleaning tool mounting

To mount or dismount the brush and tip for the spike (if included), use common assembly tools and leather gloves.

5.2.6 Filling the heating system with water

Water hardness must correspond to CSN 07 7401 and i t is essential, in case the water hardness does not comply, treat water in accordance with the Chap. 4. 1. Heating systems with the open expansion tank allow direct contact of the heating water with atmosphere . During the heating season the water expanding in th e tank absorbs oxygen, which increases the corrosiv e effects while there is a considerable evaporation o f water. To refill, only water treated according to CSN 07 7401 may be used. The heating system must be thoroughly flushed in order to wash out all impurities. During the heating season it is necessary to keep a constant volume of water in the heating system. When refilling the heating system with water it must be ensured that no air is sucked into the system. Water from the boiler and the heating system must never be discharged or taken for usage except for the emergency cases like repairs etc. Water discharge and filling with new water increases the danger of corrosion and scale development. If it is necessary to refill water in the heating system, re fill water only into the cold boiler in order to pr event cracking of the sections. After filling the boiler and the heating system, al l connections tightness should be checked. When using the two-way safety valve DBV 1 - 02, the cooling water is refilled gradually into the retur n water.

The assembly completion and heating test execution must be recorded in the "Warranty card".

6 Putting into operation – instructions for contrac tual service organization

Putting into operation can be performed only by spe cialized installation companies authorized to carry out this activity.

6.1 Verification activities before start-up

Before the boiler commissioning it is necessary to check:

1. Filling the heating system with water (check thermomanometer) and tightness of the system.

2. Connection to the chimney – this connection can be made only with the agreement of a chimney firm (chimney revision).

In case the chimney doesn’t comply with the require ments for minimum chimney draught, specified in tables No. 2, 4 and 5 (0,20 – 0,25 mbar depending o f fuel type), we recommend using an exhaust electric fan , for example, WKO 160 mm.

3. Functionality of the draught regulator and the thermostatic valve.

6.2 Putting into operation

1. Fire the boiler.

2. Bring the boiler to the necessary operating temperature. The recommended output water temperature is 80 °C.

3. Adjust the draught regulator including the chain length (according to the enclosed draught regulator manual).

4. Check the functionality of the safety equipment against overheating (after-cooling loop or two-way safety valve DBV 1 - 02).

5. Operate the boiler in operating condition according to relevant standards.

6. Check again the boiler tightness.

7. Familiarize users with the boiler operation.

8. Make a record to the warranty card.

7 Boiler operation by user

Incorrect operation and improper combustion of fuel leads to damage to the product.

During the first firing of the cold boiler, water c ondenses therein, which flows down the inner walls. The condensation of water on the boiler stops once the boiler reaches the operating temperature. When operating the boiler at the temperature lower than 60 °C, water can condense on the boiler drum, that can lead to the so called low-temperature corrosion , which shortens the life of the boiler exchanger. Therefore we recommend to operate the boiler at 60 °C and higher. LIGNITE The most suitable fuel is lignite with the grain size of 20-40 mm. Burning time at rated output is 4 hours. HARD COAL The most suitable fuel is hard coal with the grain size of 20-40 mm. Burning time at rated output is 4 hours. WOOD

To achieve the rated output of the boiler, wood moisture content must be max. 20%. Fuel must be stored in a dry place. The grate cleaning is done so that the not hot fuel falls down to the ash-pan. Tab. №. 8 Recommended dimensions of wood blocks sections number 7 block diameter [mm] Ø 40 to 100 block length [mm] 280 - 300

Guarantee of the clean and good combustion is using only dry natural wood.

Wood moisture content must be max. 20%. If the wood moisture content is higher than 20%, the boiler output declines. Damp wood burning releases water w hich condenses on the walls of the boiler and the chimney, this leads to an increased formation of ta r and water vapour, which reduces the life of the h eat exchanger. Furthermore, improper combustion causes corrosion of cast iron, the so called "metal dusting", which leads to carbon diffusion into the material, and thereby the degradation of the materi al to powder (dust). This process is gradual and prolonge d. The flue gas stream with solid particles then ca uses abrasion or erosion of the material from the surfac e, which leads to gradual thinning of the section w alls, and this may cause perforation of the boiler body.

Fuel must be stored in a dry place.

For heating, do not use plastics, household waste, chemically treated wood residues, waste paper, wood chips, brushwood, waste from pressed sheets of bark or chipboard.

▶Follow the instructions for the boiler operation. ▶When operating the boiler follow the recommended op erating temperature. ▶When operating the boiler, use only approved fuel.

7.1 Firing

1. Check the water volume in the heating system on the thermomanometer.

2. Open the shut-off valves between the boiler and the heating system.

3. Set the smoke flap in the smoke adapter into the open position.

4. Clean space at the bottom of the lining (under the tertiary air nozzle), grate, ash-pan, smoke channels and walls of the boiler.

5. Put layer of paper on the cleaned straight part of the grate though the stoking door.

6. Put 8-10 cm thick layer of fuel (thin sticks) on the paper layer.

7. Ignite the kindling.

8. Close the stoking door and open the lower choker of the ash door.

9. By means of the lever, open the shorting flap over the stoking door choker (the flue gases are discharged partially through the shorting opening into the chimney and heat it).

27

10. Let the fuel flare up until a hot mass is formed and the chimney is sufficient warmed up.

11. Put the thin layer of the basic fuel on the burning wood.

12. After its flaring up, put more fuel up to the upper edge of lining, to close the shortening valve.

13. For heating with hard coal, adjust the set screw of the lower choker of the secondary air supply under the fuel approximately to 2 to 3 mm. For heating with firewood and lignite, the lower choker remains closed.

14. Set the draught regulator at the top choker to the desired temperature.

15. By inserting the rod in the upper right part of the boiler, open tertiary air supply to the combustion chamber (open the tertiary air choker at 5 mm).

7.2 Operation

1. After reaching the heating water temperature, adjust the combustion air supply. Output control is made by the choke on the stoking door which regulates the air supply over the fuel by means of the draft regulator or adjusting screw of the choker. The draught regulator has to be adjusted so as the choker of the stoking door is slightly closed at 3-4 mm at the moment the desired temperature of heating water is reached.

2. According to heat needs and burning intensity, it is necessary to refuel during the boiler operation. Hot layer suitable for adding the fuel is about 15 cm. Before adding the fuel, make manual cleaning - from below, through a hole in the lower part of the grate, and through the stoking door for firewood. Before refuelling, release the orifice of the hole in the bottom part of the lining of the combustion chamber so as to allow continuous fuel burning off. Max. fuel filling height is determined by the upper edge of the inclined grate.

3. Before refuelling, it is recommended to open the shorting flap located above the stoking door choker, wait about 15 seconds until the flue gas is drawn to the chimney, and after refuelling, close it again.

4. The ash door must be permanently closed during the operation.

5. If necessary, clean the ash-pan (the gloves needed).

6. In case the shut-off valves are installed, the safety valve must be mounted between the boiler and the shut-off valve.

7. We recommend to clean the filter after the heat test and then before the heating season starting.

28

8 Maintenance 1. Check and if necessary remove ash from the ash-pan because full pan prevents the proper distribution of

combustion air under the fuel and causes unequal burning of the fuel on the grate. Remove all fuel remnants in the furnace and in the burn-off hole before each new firing. Because of the high temperatures reached during the combustion, the combustion chamber lining does not clog and it is not needed to disassemble and clean it. The ash must be put into incombustible containers with lids. During the work, it is necessary to use protective equipment and ensure personal safety.

2. 1x per week, clean the boiler walls inside the furnace, boiler smoke drafts and smoke adapter with a brush (cooled down boiler, the temperature does not exceed 40 °C). For the ash removal from the smoke adapter, use the cleaning cover at the its bottom part. When dismantling the cleaning cover, loosed the screw securing the latch to avoid its damage. After cleaning the smoke adapter, mount the cleaning cover back and pay attention to the tightness of the cleaning cover and the smoke adapter.

3. If using fuels with higher development of gas leading to tar depositing on the walls of the fuel space, remove it by scraping or burning dry hard wood (or coke) at the boiler max. operating temperature.

4. After the heating season, clean the space behind the choker of the tertiary air inlet, treat the pivots of the smoke flap, shorting flaps and all doors.

5. Cracks caused by tension or slight corrosion on the refractory lining are caused by temperature fluctuations and the temperature over 1000 °C in the combustion chamber. Decisive for the functionality of the device is the dimensional stability of the components. Cracks do not affect the functionality and can be considered, similar to the tiled stove, normal.

6. If there are impurities on the cover parts and control elements, it is best to remove them with a soft damp cloth. We recommend gentle cleansers without solvents. Solvents such as alcohol, gasoline or thinners should not be used because they could damage the surface of the device.

7. We recommend to clean the glass part of the stoking door more often and do not let the creation of the too thick layer of sediment. We recommend to use products for cleaning glass of fireplaces and stoves. When cleaning, follow the detergent manufacturer's instructions.

9 IMPORTANT NOTICE 1. The boiler can be operated only by adults famili ar with this instruction manual. Do not leave

unattended children near the boiler. Interventions into the boiler design that could threaten the heal th of operators or housemates are forbidden.

2. The boiler is not intended for use by persons (i ncluding children) whose physical, sensory or menta l disability or lack of experience and knowledge prev ents them from using the appliance safely, if they are not supervised or were not instructed to use th e appliance by a person responsible for their safet y.

3. Children should be supervised to ensure that the y do not play with the appliance.

4. If there is a danger of development and penetrat ion of combustible vapours or gases into the boiler room or at works with temporarily developed fire or explosion danger (gluing the floorings, painting with flammable paints), the boiler must be put out of operation before such works.

5. IT IS FORBIDDEN to use flammable liquids for the boiler firing.

6. IT IS FORBIDDEN to overheat boiler during operation.

7. Do not put any objects made of flammable materia ls on the boiler and within a distance smaller than the safe distance from the boiler.

8. When removing the ash from the boiler, no flamma ble substances must be at the minimum distance of 1500 mm from the boiler.

9. When operating the boiler at the temperature low er than 60 °C, water can condense on the boiler dru m, that can lead to the so called low-temperature corr osion, which shortens the life of the boiler drum. Therefore we recommend to operate the boiler at 60 °C and higher.

10. In case of the storage tank use, the boiler can be again lit or the fuel can be added if the boiler is burned to the base of the fireplace and the storage tank is empty or cooled. ATTENTION! Ignoring leads to extreme heat exchanger clogging.

29

11. After the heating season, it is necessary to cl ean the boiler, the flues and the smoke adapter. Sp read the graphite grease on the pivots, the smoke flap m echanism and other moving parts on the boiler. The boiler room must be kept clean and dry.

12. If the heating system is not used daily during the winter period, it is necessary to drain the wat er.

13. Possible signs of corrosion on the boiler drum are not defects and do not affect the boiler functi on.

14. In the system, it is necessary to install a saf ety valve with max. overpressure of 400 kPa (4 bar) , which dimensions must correspond to the boiler nominal ou tput. The safety valve must be installed immediately behind the boiler. Shut-off valve must be installed between the safety valve and the boile r. For further questions please contact our contractua l installation companies and service organizations.

15. In case of reaction of the two-way safety valve , when there could be refilled water that does not conform to CSN 07 7401, it is necessary to adjust w ater in the system so that it again conforms to thi s standard.

16. When mounting, installation and operation of th e appliance it is necessary to meet the standards v alid in the relevant destination country.

In case of failure to comply with these conditions, warranty repairs cannot be claimed.
