6 BOILER FEATURES 1 Boiler features 1.1 General information The Biotec Boiler has a modern design and is made of high quality material. The boiler tests were carried out conforming to EN 303-5, therefore the boiler fulfils all requirements for the connection to a central heating system. The maximum permitted system pressure is 2.5 bar. This boiler is suitable for central heating system of familyhomes, small businesses or workshops. The automatic operation is very user-friendly, because the only action during operation is re-filling the pellet silo depending on the usage. The Biotec includes the silo and pellet screw with the silo on the right hand side. The silo can be mounted on the left hand side on application and at extra cost. 1.2 Conformity declaration The company STREBEL confirms according to EN45014:1998 tha the boiler Biotec complies with the following standards: EC-guidelines: MD 98/37/EC PED 97/23/EC LVD 2006/95/EC EMC 2004/108/EC General standards: EN 303-5:1999; EN :2006; EN :2002; EN 50165:1997+A1; EN :2001; EN ISO :2003; EN ISO :2003; EN 1050:1997 Other standards and technical specifications: EN 287-1:2004, EN 288-3:1992; EN 10204:2004; EN ISO 7000:2004. Testing method conformity: Module B1 Limit of Emission combustion products (class) 3 Certificates: EC Control Type Certificate Nr. 0745/350/09 STREBEL Responsible laboratory: TÜV Thüringen e.v. Service- Centre South Germany, Industry.13, D in the town Zella Mehlis We hereby declare that the stated products were produced under safety and specific guidelines and standards. All working conditions and terms of use comply with this manual. Wood pellets are an excellent renewable fuel they are cylindrical in shape with a low ash-percentage after combustion which accounts for about 1 %. The caloric value of pellets is approx kj/kg, which means that 2 kg pellets is roughly equivalent to 1 ltr of light heating oil. If the product is changed and changes are unapproved by Strebel the above confirmation loses its validity. The storing qualities and the high energy value of pellets make them the ideal replacement for oil or gas. 6

12 FLUE DIAMETER IN CM 5.2 Installation of the chimney INSTALLATION The boiler must be installed near a chimney. It is prohibited to close air vents. DANGER Insufficient flue draught can cause a fire which can spread from the burner on to the screw and then to the pellets in the silo. This must not happen however a safety extinguishing valve is fitted as standard. 1.) The boiler must be placed on a solid and stable floor. 2.) The installation must be carried out by qualified technicians and the electrical supply must be to regulations 3.) The boiler room must have a water supply 4) Servicing access should be considered 5) A waste water drain is useful. 6.) The boiler room must have ventilation to current regulations 7) Floor, walls, ceiling, door and equipment of the boiler room must be made of non-flammable material. 8.) Humidity should be kept at a low level to avoid corrosion of metal parts. 9) For filling the boiler we advise the use of soft water ) The circulation pump must not operate before the heating system is completely filled with water. The system must be bled of air completely 11) When connecting the boiler to the flue it is necessary to make sure that all connections are sealed properly. 12) Before the first start-up, check the position of the combustion chamber bricks. 13) Consider protection from freezing. 1.5 TO 3MT 1500mm FIRE BRICKS 12

13 INSTALLATION 5.3 Connection of the boiler parts To prevent the system freezing when the boiler is not to be used for a long period of ELECTRICAL time, we advise draining the system. Connect the pump to the power supply. (max. current 1 A). Connection of the controller Connect the controller to the power supply. The installation of the electrical accessories of the boiler need a power supply with 230 V/50 Hz. Connection of the room thermostat A room thermostat can be connected to the controller. Before starting up the boiler, check the following: HYDRAULIC 1.) Water pressure in boiler and system is adequate. 2.) The system must be bled of air 3.) The boiler wiring is installed correctly and is undamaged and not touching surfaces that heat up during operation. 4.) The combustion chamber bricks are correctly positioned 5.) The pellet silo is clean. A certified safety valve (2.5 bar) must be installed in the heating system. Do not install other valves between the safety valve and boiler The return temperature must not fall below 60 C to prevent the build of condensate inside the boiler. When the boiler is not producing heat, other heaters should be in place to protect the Boiler and system from frost where freezing could be imminent 13

20 7 Operational phases OPERATIONAL PHASES 7.1 Ignition phase If the flue gas temperature is above the temperature requiring auto ignition of the pellets, the controller knows that the combustion chamber holds enough ember temperature to successfully continue combustion. In this case the ignition device is not required. The dosage of pellets continues. If the flue gas temperature shows the temperature to be low the controller knows that the combustion chamber has not enough ember temperature to successfully continue combustion. First the fan is switched on to clear the combustion chamber and vents below the ignition device Second the pellet auger pushes enough pellets for light up into the combustion chamber. If a room thermostat or on off control (if used ) switches off, it activates the setting that turns off the boiler and therefore it sends the boiler into a phase of after-run., the boiler will then quickly reach the required temperature and operation will stop. The pump will start if the boiler temperature rises beyond the required temperature and also if the room thermostat demands heat. If the room thermostat /control does not call for heat the pump runs for a period of 5 minutes after the boiler has switched off then the pump stops until the room thermostat/ control calls for heat again. Third the ignition device is switched on The Boiler now enters the warm up phase of operation 7.2 Warm-up phase The ignition device is switched off and the dosage of pellets is reduced. The fan runs with increased speed (according to the setting). in comparison to the combustion phase. The warm-up phase has the purpose to fan the fire and let it spread across the pellets in the combustion chamber. The duration of the warmup phase is fairly short. After this phase, the combustion phase starts. In the case that the flue gas temperature does not rise beyond a pre programmed set temperature the controller recognises that the pellets can not be burning and the boiler stops operation. The display shows FAILED IGNITION. 7.3 Combustion phase During combustion phase, the pellet and air supply are regulated based on the parameter settings. The controller aims for the boiler to increase the temperature up to the Maximum boiler temperature. when this is reached the boiler slowly reduces its output to prevent repeated turning off and on. The boiler shifts to pause mode when the temperature reaches the Maximum boiler temperature. On the top row the display shows Rated temp reached. The boiler re starts operation when the temperature of the boiler flow drops below the set parameter Maximum boiler temperature. The detected flue gas temperature determines if the boiler operation starts with the warm-up phase or the ignition phase as described above 20

21 8 Maintenance MAINTENANCE 8.1. Intervals of maintenance and cleaning Maintenance work performed periodically is very important for a problem-free operation and the guarantee of a long life of the boiler and other system components. The maintenance period is affected by to the pellet quality and boiler usage. Soot and tar cling to the combustion chamber walls, so their cleaning by hand.is very important Before you start cleaning, turn off the boiler controller and deactivate the main switch. Let the boiler cool to a safe temperature that is not a burn or injury risk Interval Every 3 days Components Clean the heat exchanger and combustion chamber Action Required Move the lever of the heat exchanger cleaning system back and forth 5 to 6 times. Remove the front refractory brick and clean the combustion chamber with a vacuum cleaner. Every month Clean the pellet silo Empty out the pellet silo and remove any wood dust with a vacuum cleaner. Clean the display Carefully clean with slightly damp cloth. Every 6 months Check and clean the flue exhaust passes Check and clean the boiler and flue gas probe The exhaust pipes can be removed and cleaned with the cleaning tool when the system is cooled down. Once a year Clean all part as stated As above & pull out the probes, remove soot and debris. When cleaning the combustion chamber with a vacuum cleaner, the ash inside must be allowed to cool down to prevent accidents. When removing the front brick of the burner, there is a risk of a burn injury Wait for the brick to fully cool down. There is a risk of burns when cleaning the exhaust passes because these surfaces can reach a temperature of up to 200 C during operation. Wait until these parts cool down fully before cleaning. While cleaning, be aware that deadly carbon DANGER monoxide can emit from an opened boiler door or cover. Do not leave the boiler doors open longer than necessary. The ash quantity in the boiler depends on the pellet quality and usage. High quality pellets leave less ash and reduce wood dust in the pellet silo. To prolong the live of the ignition system which ignites the pellets, the ignition system and the air vent must be cleaned regularly. Thoroughly clean the boiler system at the end of the heating season to prolong its live and maintain its efficiency. 21

22 POSSIBLE FAULTS 9 Possible faults 3) The refractory bricks in the combustion chamber are misaligned System dirty 22

23 POSSIBLE FAULTS COMMISSIONING Fire Prevention of the Biotec Thermal valve If the boiler is not connected to a suitable flue system (not enough height, wrong diameter of the chimney, dirt or heavily polluted boiler), there is a possibility that fire can spread from the burner into the silo. A part of the combustion air supply is led through the screw channel and thus prevents backfire in the pellet silo. This air current is present at all times during operation but if the flue gas system is badly designed or heavily polluted, the air supply may not be enough to stop the fire spreading up the auger feed. A thermal valve and a probe are mounted on the boiler ex works. If a temperature of 95 C or more is measured by the inbuilt thermal valve (in the auger feed) it is activated and releases water extinguishing the fire The buyer must provide a water supply to the thermal valve (1/2 connection) and comply fully with regulations in force. If the flue gas system is designed incorrectly or heavily polluted or if the boiler is not cleaned regularly or the water supply fails, the manufacturer is not liable for damage caused by such failures. probe Boiler auger showing the thermal valve and probe 10 Commissioning the Biotec Boiler The commissioning of the Biotec boiler may only be carried out by STREBEL or an experienced installer with the approval of Strebel If the start-up is not carried out correctly, the boiler and the system can be damaged or destroyed and be unrepairable.
