1. Introduction Dear customers, you have just opened a catalogue called Technical Documentation for BENEKOV products. You will find here basic information on the possibilities of heating of your buildings by automatic boilers using solid fuels, the advantages which our technology brings to you and the know-how you may acquire through cooperation with us. Saving does not concern only fuel costs One of the key motivations for investment into an automatic solid fuel boiler is heating costs saving and this may apply to single family houses as well as to factory buildings, school buildings or other large structures. Today the efficiency of combustion of approximately 90 % is commonplace for modern automatic boilers. Besides efficient heat exchangers, we offer much more to the users in terms of technology. The motors with flat gearboxes and EC fans controlled by PWM signal consume less power than a light bulb and by using them customers save up to tens of thousands of crowns during boiler service life compared to electrical components commonly used by other manufacturers. The possibility to incinerate various kinds of fuels in one boiler increases long-term independence. In the case of a substantial change of fuel prices, the user of the boiler has the possibility to convert in the future to another type of fuel more economically convenient at that given time. In today's situation of fluctuating prices of raw materials this is a major advantage compared to technologies that are able to burn only one type of fuel. High automation of boilers means lower time demands of boilers in terms of operation which results in time saving. We are very particular when selecting quality suppliers of purchased material. We purchase all electrical components from globally renowned manufacturers such as Siemens, EBM, TOS, etc. Due to that, when you invest in our equipment, you obtain equipment with long service life and your costs may thus return with even greater efficiency. However, heating is not only the matter of the actual boiler - in order to achieve minimal operating costs it is always necessary to find the right comprehensive and individual solution for the given heating system. This document is intended to help you find a more efficient heating system to meet your needs and it will help you select suitable components and a connection diagram.

2. DIVISION OF BENEKOV PRODUCT RANGE The Technical Documentation is drawn up for sheet-steel boilers for solid fuels or biomass with automatic stoking up to the output of 100 kW. These automatic boilers are designed for heating of single-family houses, family hotels, industrial plants, etc. All automatic boilers stated here meet at least emission class 4 and biomass boilers class 5 according to ČSN EN 3O3-5 standard. Boiler bodies are insulated by harmless mineral insulation, which decreases the loss due to transfer of heat to the surrounding environment.

Boiler casings have surface treatment by quality powder coating. 2.1 Automatic boilers with output modulation and equithermal heating control The boilers are fitted with Siemens CLIMATIX controllers allowing two-circuit equithermal control of heating with a link to internal temperature using an outdoor temperature sensor and room thermostat. Heating control is implemented by means of mixing valves with servo actuation, turning off the boiler and modulation of its output within the range of 30 – 100 %. Boiler electronics also controls heating of HW in the storage heater and accumulation. Controller Siemens Climatix II is able to regulate the cascade up to 4 boiler, has the internet connection and is possible to connect the expand module Siemens POL 638.70 which can regulates other 4 mixing circuits. Individual types of boilers: 4. emission class according to ČSN EN 303-5:2013 standard

When designing utilization of these boilers, turn to BENEKOVterm technical department.

3. Common requirements for mounting and operation According to the effective Claim Rules, the manufacturer designates companies for boiler installation with effective certificate for mounting of its boilers. The manufacturer designates companies for commissioning of its boilers with effective certificates for boiler commissioning. When these two above-mentioned prerequisites are not met, the guarantee is not effective. A project conforming to effective regulations needs to be drawn up for the installation of the boiler. Transport of the boiler to the boiler room may be performed in disassembled condition. The boiler must be mounted in a level position. 3.1 Protection against low-temperature corrosion Even automatic boilers with modern design are subject to the so-called low-temperature corrosion. Low-temperature corrosion occurs on heat transfer surfaces of a boiler in the case that the temperature of the return water drops below the dew point of flue gases. Therefore boilers need to be protected against occurrence of low-temperature corrosion either by a thermostatic mixing valve or by another way (superior control) so that the return temperature is kept at 50° - 55°C.

We recommend using of thermostatic mixing valve with temperature cartridge 50°C, max. 55°C. In the case of boilers with modulated output, we recommend using of mixing valves with actuation from Siemens company marked SXP 45…, which are powered by 24V AC/DC and controlled by signal 0-10 VDC. 3.2 Fuels Using proper fuel is an important element for operation of boilers with automatic stoking. Boiler outputs stated in Operating Instructions for individual boilers were achieved during measuring by SZÚ. During these tests, specified fuels were used with the following parameters: Wooden pellets Pellets must conform to ČSN EN 14961-2 - grade 6 to 14 mm - length max. 30 mm - bulk density 600 – 650 kg/m3

- water content max. 22 % - ash content max. 1.5 % - calorific value min. 17 MJ.kg-1

Lignite Ořech 2 - grade 10 – 25 mm - calorific value min. 17 MJ.kg -1 - ash content max. 12 % - water content max. 20 % - ash fusing point min. 1500 oC - sulphur content max. 0.9 % - specific sulphur content max. 0.5 g/MJ - bitumen content max. 3.5 % Recommended fuel is from Bílina strip mine, Ledvice treatment plant. Wood chips - cross-section max. 10x20 mm - length max. 30 mm - bulk density 200 – 300 kg/m3 - water content max. 25 % - ash content max. 3.0 % - calorific value min. 13 MJ.kg-1 Poor fuel quality may negatively affect output and emission parameters of boiler. In order to secure proper combustion in the boiler, the fuel needs to be dry. The manufacturer recommends the fuel be stored in a basement or at least under a shed. It is forbidden to store the fuel behind the boiler and to store it next to the boiler at a distance smaller than 400 mm.

The manufacturer recommends that the minimum distance between the boiler and the fuel be 1,000 mm, or the fuel be placed in another room than the boiler room. 3.3 Heating system requirements Heating system must me filled by water which conforms to ČSN 07 7401 standard, especially the hardness cannot be over the required parameters. Optimum conditions for operation are provided by a closed system fitted with an expansion pressure vessel with diaphragm. The heating system needs to be flushed properly in order to remove all impurities. Water from the boiler and the heating system must not be tapped for use. If the heating system is connected by fixed piping to a drinking water source for adding water into the system, the connection must be implemented via special separating valve (check valve is not enough). Water must not be contaminated by return leak from service water system. Water may be added only to a cooled down boiler. A drain cock needs to be placed in the heating system at the lowest point and as close to the boiler as possible. 3.4 Flue gas exhaust There are extraordinary requirements for flue gas exhaust of all automatic solid fuel boilers. Unlike solid fuel boilers with manual stoking, the cycles here are much more frequent. When the boiler is started into a cold stack, condensate is formed and it pours down on stack walls. During short boiler operation runs, the stack does not get warmed up properly. In the case that the boiler is operated at a reduced power, the described condition is even more marked. Connecting of a boiler to flue gas exhaust needs to be designed as vacuum exhaust. The minimum values of stack draught are stated in individual Operating Instructions for individual boilers. The flue gas route must be tight and with the so-called wet design for condensing operation. The material is specified by ČSN 73 4201. The specified material here is stainless steel according to ČSN EN 10088-1, material 1,4404, minimum th. 0.8 mm, or material 1,4432 minimal th. 1.0 mm. By neglecting the above-mentioned instructions, sooner or later the stack body gets damaged. Design of the stack needs to be implemented according to local conditions with regard to the output of the boiler, height and the way of outlet of the stack, altitude of the structure. Air supply needs to be secured to the boiler room. Designing of gas flue route is implemented to the minimum specified draught specified in the table for the given boiler. In practice, especially with higher stacks, in very cold temperatures the stack draught is significantly increased. The given fact results in a change of combustion conditions in the hearth, through which higher amount of air passes than necessary for combustion. In this way, boiler efficiency is decreased, as the excessive air only warms up and subsequently goes into the stack. A solution to this issue is installation of draught controller. The draught controller is mounted on the smoke flue or into the stack, however, always in the boiler room. The draught controller is adjusted by means of draught gauge to the value by 3 – 4 Pa higher than the specified stack draught (usually implemented by chimney sweeper). When the draught is exceeded, the controller flap is gradually open and in this way additional air is brought to the stack. As a result, draught in the stack decreases. The controller works continuously without the need of any other energy.

The draught controller is included in recommended accessories, it is not directly prescribed. In the case of substantial changes of draught conditions in the stack, where in extreme flame separation could occur, the mounting of draught controller is a reliable and recommended solution. In the case of automatic boilers, we recommend using of a draught controller for each installation. In the case that the stack is not made of stainless steel, mounting of draught controller to protect the upper part of the stack is helpful. In the breaks between heating, air is supplied to the heated stack which warms up at the bottom of the stack and helps dry the top part and prevent its wetting. In the case that more appliances are connected to one vent stack at several rooms, the draught controller must not be used. Before the boiler is put into operation, an inspection report of flue gas route must be issued. Inspection of the flue gas route is carried out by a professionally competent person who has trade license in chimney sweeping and who is an inspection engineer at the same time. The inspection is carried out every year. 3.5 Mains connection With most boilers it is necessary to secure connection to low voltage network 1 PEN – 230 V/50 Hz, TN-S. Only in the case of BENEKOV S boiler, the connection to the low voltage network is 3 PEN 3 x 400/230 V / 50 Hz, TN-S. The boiler is connected by fixed connection with flexible cord terminated with a standardized plug. Protection against electric shock must be secured according to effective ČSN EN standards (their list see Boiler Operating Instructions). 3.6 Installation of boiler with respect to fire safety regulations During installation and use of the boiler, all requirements of ČSN 06 1008 must be observed. 1. Placement on the floor of a combustible material

- place the boiler on a non-combustible, thermally insulating pad exceeding the boiler top view on the sides by 20 mm.

2. Safe distance from flammable materials:

- during installation and operation of the boiler, it is necessary to observe a safe distance of 200 mm from flammable materials with combustible class A1, A2, B and C (D);

- for lightly combustible materials, combustibility E (F), which burn quickly on their own even when the source of ignition is removed (e.g., paper, cardboard, carton, asphalt and bitumen sheets, wood and chipboards, plastic materials, floor coverings) the safe distance is doubled to 400 mm;

- the safe distance also needs to be doubled in the case that the class of combustibility is not proven.

Table of construction materials according to the class of reaction to fire Reaction to fire class Examples of construction materials and products included in reaction

to fire class (selection from ČSN EN 13 501-1+A1)

A1 - non-combustible granite, sandstone, concrete, bricks, ceramic tiles, mortar, fire resistant plaster, etc.

A2 – not easily combustible Akumin, Ozimin, Heraklit, Lignos, boards and basalt felt, boards of glass fibre, etc

B – combustible with difficulty Beech, oak, Hobrex boards, plywoods, Werzalit, Umakart, Sirkolit, … C(D) – medium combustible Pine, larch, spruce, chipboard and cork boards, rubber floor covering, etc. E(F) – easily combustible Asphalt sheet, fibreboards, cellulose materials, polyurethane, polystyrene,

polyethylene, PVC, etc. 3.7 Relief valves A relief valve needs to be mounted on the outlet side of the boiler (with the exception of situation when the relief piping is directed into an open expansion tank). The relief valve is a securing device here by course of ČSN 06 0830. The maximum distance of the placement of the relief valve from the boiler is 20 x DN of the outlet piping from the branch of connection to the boiler, i.e. the securing site. No closing valve may be placed between the boiler and the relief valve. The relief valve must be approved by an authorized body (testing organization). The 200 kPa relief valve is sufficient for all boilers considered here. A storage tank and a storage water heater (if installed) also need to be provided with a relief valve. In the case of a storage water heater, the relief valve is usually included in the supply from the manufacturer as a combined relief and check valve. 3.8 Expansion vessels An expansion vessel for the heating system and the storage tank It is recommended that pressure expansion vessels with a diaphragm be used where there is no contact of the heat transfer medium (water) with the surrounding air. Rating of the vessel is carried out according to the hydraulic head, heating temperature and the volume of water in the system. The expansion vessel creates in the central heating system the so-called zero point and therefore it always needs to be connected on the intake side of the circulating pump. If it be to the contrary, the circulating pump would decrease pressure in the system by its delivery head. The expansion vessel needs to be protected by a relief valve with opening overpressure maximally equal to the designed pressure of the expansion vessel and no closing valve may be mounted on the section from connecting of the vessel to the system to the relief valve. A closing valve is mounted before the expansion vessel for the needs of inspection and pressure setting in the vessel. After the closing valve (in the direction to the expansion vessel) there is no other source of pressure. The closing valve is provided with a drain cock on the side of the vessel. A 25-30 litre expansion vessel is sufficient for application in common single-family house systems where no storage tank is installed. Overpressure in the vessel needs to be adjusted annually but in practice this is not always observed. Therefore in the case of a greater vessel, slight leaks of water during bleeding and such like are covered for the longer period. The gas overpressure slowly and gradually drops in all pressure vessels. It is recommended that

quality vessels be used with diaphragm or bag of polybutylene, which has substantially lower diffusion of molecules of air into water compared to standard EPDM material. Rating of expansion vessels is not subject to this documentation and should be included in a heating system project. In the case that storage tanks are used in heating systems, it is necessary to plan for 43 litres of expansion vessel content for every 500 litres of a storage tank. If the tank receives heat from solar connectors, its temperature may reach over 900C and the volume needs to be increased even further. The given facts are true for a single-family house with the hydrostatical head of the heating system of up to 5m and a 250 kPa relief valve. If the hydrostatical head is 7 m, then the requisite volume of expansion tanks is 49 litres per 500 litres of storage tank volume. The stated volumes need to include the boiler and the central heating system. Every storage tank needs to be fitted with a relief valve with the rating according to the safety pressure and output. It is suitable that a storage tank be fitted with a separate expansion vessel. The minimum water pressure in a central heating system and the filling pressure of the expansion vessel on the gas side is set according to the hydrostatical pressure of the system or its head. The minimum gas overpressure in an empty expansion vessel is to be by 0.03 MPa higher than the hydrostatical pressure in the system. The minimum pressure of water in a central heating system is to be by at least 0.06 MPa (6 m of water column) higher than the hydrostatical pressure in the system. If allowed by the size of the expansion vessel, we opt for appropriately higher minimum pressure in the system - it then reduces the demand for the frequency of checks of the condition of water and pressure in the expansion vessel and replenishments of the system. Rating of expansion vessels should be included in a heating system project. Expansion vessel for storage heater of heating water An expansion vessel should be mounted at the inlet side of a storage water heater. This vessel is to prevent dripping of water through the relief valve due to expansion during heating. In the most common applications when a relief valve is fitted with opening overpressure of 0.6 MPa and water main pressure is below 0.3 MPa, it is sufficient to have 5 litres of expansion vessel per 100 litres of the storage heater. Filling pressure on the gas side 0.3 MPa. 3.9 Device for excessive heat dissipation With regard to the fact that the selected models of our automatic boilers allow operation with manual stoking of piece wood in emergency mode, a situation may occur when the boiler is full of fuel and heat is not taken off (outage, pump breakdown, etc.). As a result, the boiler might be overheated with possible subsequent accident. Such condition needs to be prevented. A solution is provided by a two-way safety valve DBV 1-02, which is used for removal of excessive heat in the case that water temperature in the boiler exceeds 95 oC. The device is connected to a source of pressure cold water from the water main. A filter for intercepting of mechanical impurities needs to be mounted on the cooling water supply line.

In the case of overheating of the boiler, the drain valve opens at the same time and it means that cold water runs into the boiler and at the same time the hot water is drained. When the temperature drops below the limit value, the drain and supply valve both close. Cooling water mix with water from heating system. In case of opening two ways safety device can come to pass to mix with water which doesn’t conform to ČSN 07 7401 standard. Than it is necessary to correct the water in heating system. The minimum water pressure in the water main must be always greater than the limit value of the relief valve of the boiler. This device for removal of excessive heat is intended for emergency and depends on the source of cold pressure water from the water main. The boiler room needs to be provided with a drain; the drain from the emergency assembly must be designed so as to prevent scalding. 3.10 Piping and fittings The diagrams do not include piping dimensions. DN 20 piping and fittings are recommended for boilers with the output of 15 kW. DN 25 piping and fittings are recommended for boilers with the output of 20 kW. DN 32 to DN 40 piping and fittings are recommended for boilers with the output of 45 - 50 kW. In the case of boilers with the output of 99 kW we recommend DN 50 dimension for output distribution. 3.11 Circulating pumps A common uncontrolled pump (e.g. Grundfos UPS, 100 series) is suitable for the primary circuit of the boiler and the circuit of a storage water heater. Electronically controlled pumps (e.g., Grundfos ALPHA 2) are used in mixing circuits and these are conforming to the European EuP standard. In the case that thermostatic valves are fitted in the system, the use of electronically controlled pumps is necessary.

4. Examples of recommended connections This chapter includes examples of recommended connections of boilers into heating systems. The diagrams do not include additional fittings (valves, filters, etc.). In case of hydraulic connections no. 9, 10, 11, 12, 13, and 14 is possible to get the prolonged warranty. 4.1 Connecting of boilers with Siemens Climatix 2 modulated controller The diagrams No.9 to No.11 show hydraulic systems with Siemens Climatix II controller.
