8 2.5. Fuel Wood pellet is a primary fuel used in the KSP Spark: PN-EN ISO :2014 class A1. Fuel used for combustion in the boiler should have sufficient calorific value > 17 MJ/kg, be dried (moisture content ~ 10%) and have size recommended by the producer 6±1 mm. Use of moist or too large fuel can lead to locking in the feeder and serious failure of the boiler. Ash content should be lower than 0.5%, the unfavourable chemical composition of the fuel can result in sintering and formation of large amounts of dust and soot and increased fuel consumption. 3. BEFORE START-UP 3.1. Boiler setting The boiler requires non-flammable flooring, in form of a foundation, but it is allowed to place it on non-flammable wall base with height not lower than 50 mm. The boiler should be placed in a way ensuring free access to the equipment, allowing its cleaning and maintenance. Therefore it is recommended to maintain the minimum distances when the boiler is set: distance from the front of the boiler to opposite boiler room wall should not be smaller than 2 m, Operation and maintenance manual, the distance of boiler side from the wall of the boiler room should be lower than 1 m, the distance of rear part of the boiler from the wall of the boiler room should be equal to at least length of the connection, that is 0.25 m. The room, where the boiler is located, should have gravity ventilation in good working order, including: 1. air-supply duct in the external wall with cross-section not lower than 50% of chimney cross-sectional area on height maximum 1 m over the flooring or not lower than 200 cm 2 for boilers with power up to 25 kw or 400 cm 2 for boilers over 25 kw, 2. separate air-exhaust duct on the internal wall with cross-section not lower than mm with an outlet located under the boiler-room roof near the chimney. NOTE! It is forbidden to use mechanical exhaust ventilation in the room where the boiler was installed. 8 Page Operation and maintenance manual for the KSP Spark series boilers equipped with feeders. The producer reserves the right to introduce technical modifications.

9 3.2. Connection to chimney 1. It is necessary to prepare stand-alone, tight chimney flue, which will be used for flue gas flowing from the boiler. 2. The flue should be placed at least 0.5 m over the roof ridge to avoid the occurrence of backdraught. The intersection of the flue should be appropriately selected for the boiler power and height of the chimney. The minimum cross-section of masonry chimney should not be lower than cm! The intersection of non-insulated steel chimneys should be bigger by 20%. NOTE! It is recommended to use chimney system resistant to corrosion, with a decanter for condensate, due to the high efficiency of the boiler and low temperature of flue gases <120 C. Additionally the chimneys led outside the building require insulation. 3. Check condition of the chimney (preferably by a chimney sweep) before connecting the boiler to the chimney and check whether the chimney is free from connections of the heating elements. 4. The boiler should be connected with chimney using a connector. It is not recommended to use the connection at a straight angle because it will cause a loss in the chimney draught. Flue with chimney should be joined with a connector made of steel sheet. We put it on the outlet from the flue, fix on the chimney and seal with high-temperature silicone. The connector should be directed slightly upwards from 5 to 20. If boiler flue will have a length over 400 mm then it is recommended to insulate it with a thermal insulation. NOTE! The KSP Spark boilers heater should be installed in accordance with the applicable Regulation of the Minister of Infrastructure (Journal of Laws of 2002 no. 75 item 690 and Journal of Laws of 2009 no. 56 item 461.).

12 3.4. Connection of the boiler to electrical system The boiler requires an electrical system with rated voltage with protective conductor contact with connected protective 230/50Hz in compliance with the applicable regulations. The conductor terminal PE to protect against electric shock. system should be terminated with plug-in socket equipped 3.5. Filling the system with water Filling the boiler with water before first start-up 1. Flush heating system and boiler before filling it with water to remove all contaminations. 2. Fill the system with water through the drain cock using the flexible hose. Water intended for feeding the heating boiler should meet the requirements of the PN-93/C standard. Quality of water filling the central heating system influences its durability therefore this water should be free from the contaminations, oil and aggressive chemical substances. Water hardness should not exceed 2-4 (mval/l). Too hard water causes deposition of sediment in the boiler and heating system what decreases efficiency and may damage the boiler. 3. Stop feeding of water when the system is full that is water will start flowing out from the signalling pipe of the expansion vessel located in the highest point of the system or when the pressure gauge indicates 1.5 bar. Refilling should take several seconds to make sure that the water flows down from the vessel. 4. Close boiler drain cock and disconnect flexible hose from the equipment when the system is filled Refilling the system with water Heating system with open container allows direct contact of heating water with the air what results in evaporation and necessity to refill it. NOTE! It is forbidden to add cold water to the heated up system. Adding water to heated boiler components may damage it and is synonymous with loss of the warranty. The system can be refilled with water only when the boiler is cold. Firing up should be restarted after filling the system Draining water from the system It is not recommended to drain the water from the system after the heating season because it increases the risk of occurrence of the corrosion and formation of boiler scale. The exception is a time needed to carry out necessary repair and long-term standstills of the boiler during strong frosts. In the latter case, it is recommended to drain water from the system (to avoid freezing and therefore damaging of the system) and refilling it with water when the frost is over. 12 Page Operation and maintenance manual for the KSP Spark series boilers equipped with feeders.
