The producer reserves the right to introduce technical modifications.
2.6. Fuel The basic fuel used in the Q-Per boiler is 31-2 pea coal: granulation: 5 25 mm calorific value: > 28 MJ/kg 2.7. Equipment Before setting the boiler, check additional devices and proper operation of the accessories. Complete set of components contains: assembled boiler with a feeder and hopper in the casing, moisture content: < 11% ash content: < 7% sulphur content: < 1% coaking ability: RJ < 5 electronic controller, brush, hook, ash shovel, exhaust gas swirlers and ash drawer. 3. BEFORE START-UP 3.1. Boiler room It should be a separate room with height not lower than 2.2 m in the newly constructed building (in the already existing buildings the allowable height equals to 1.9 m). It should have artificial lighting installed and have natural lighting as far as practicable. It 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, 3.2. 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. Boiler should be placed in a way ensuring free access to the equipment, allowing its cleaning and maintenance. Therefore, while setting the boiler it is recommended to maintain minimum distances from the individual walls: 2. separate air-exhaust duct on the internal wall with cross-section not lower than 140 140 mm with an outlet located under the boiler-room roof near the chimney. Floor gully and floor with 1% slope towards the outlet should be planned in the central part of the room. Flooring and walls in the whole room should be made of non-combustible materials. The doors to the boiler room should open outwards. NOTE! It is forbidden to use mechanical exhaust ventilation in the room where the boiler was installe. distance from the front of the boiler to opposite boiler room wall should not be smaller than 2 m, distance of boiler side from 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. Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications. Page 7
3.3. Connection to chimney 1. It is necessary to prepare stand-alone, tight chimney flue, which will be used for flue gas from the boiler. 2. The flue should be placed at least 1.5 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. Approximate calculations of chimney height and intersection can be carried out using a chimney intersection calculator available on the website www.pereko.pl Regardless of the results of the calculations the minimum intersection of masonry chimney should not be lower than 14 14 cm! The intersection of non-insulated steel chimneys should be bigger by 20% and the chimneys made from steel pipes should be about 15-20% higher than brick chimneys. 3. Check condition of the chimney (preferably by a chimney sweep) before connecting the boiler to the chimney and check whether the chimney if 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 of thickness 3 mm (to be purchased from the boiler producer). 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! Boilers should be installed in compliance 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.) In addition, it is recommended to use chimney liner resistant to corrosion: chemical, pitting, intercrystalline and surface. 3.4. Connection of central heating and domestic hot water system 3.4.1. Open water heating installations The Q-PER boiler is suitable for supplying open water central heating systems with gravitational or forced circulation. The system in which the boiler operates must meet the requirements of the Polish standard PN-91/B-02413 Ogrzewnictwo i ciepłownictwo Zabezpieczenie instalacji ogrzewania wodnego systemu otwartego Wymagania / Heating and district heating Protection of open water heating installations Specifications/.

3.4.2. Closed water heating installations The Q-PER boiler with automatic feeding may be used in closed water heating installations, provided that: the system is equipped with a membrane expansion vessel, a heat excess extraction device (REGULUS DBV 1 dual function cooling valve) is installed, max. 2.5 bar safety valve is installed. NOTE! These devices must be inspected at least twice a year. The first inspection must be conducted during the seasonal boiler start-up with the water heating installation. 3.4.3. 4-way valve The design of the heating system must include boiler protection against return of excessively cold water from the installation. Use of 4-way mixing valve is recommended. It allows increasing the temperature of water returning to the boiler. The 4-way valve mixes warm water from the feeding circuit with colder water from the heating circuit return, and therefore: protects the boiler against low-temperature corrosion and preliminary wear, increases the efficiency of heating of domestic water in the DHW tank, allows flexible control of heating water temperature in relation with the heating system requirements, increases the efficiency of the entire system. Design and installation of a heating system appropriate for a given building must be performed by properly qualified persons. Central heating systems may be different, thus the guidelines included in the central heating design must be followed. A sample scheme of boiler connection with the central heating and domestic hot water systems in an open heating system with gravitational or forced water circuit is presented on page 13. 3.5. Connection of the boiler to electrical system Boiler room should be equipped with electrical system with equipped with protective conductor contact with connected rated voltage 230/50 Hz in compliance with the applicable regulations. protective conductor terminal PE to protect against electric The system should be terminated with plug-in socket shock. 3.6. Filling the system with water 3.6.1. 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-04607 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 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. 10 Page Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.
3.6.2. 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 hot system. Adding water to hot components of the boiler 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. 3.6.3. 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 to the system) and refilling it with water when the frost is over.

4. SERVICE MANUAL 4.1. Safe operating conditions To maintain safe operating conditions for the boiler you should: Execute heating system correctly in compliance with the requirements of the standards: PN 91/B-02413, applying to the protection of open water heating installations, considering the Regulation of the Minister of Infrastructure, Journal of Laws of 2009, no. 56, item 461. Fill the system with water correctly. Do not refill the system with cold water during operation of the hot boiler. It is forbidden to operate the boiler if the water level in the system is below the level indicated in the central heating system user manual. Never use flammable liquids, e.g. petrol, for firing up. Do not extinguish the fire in the furnace by pouring it with water. Use suitable equipment and protective clothing (gloves, goggles, head protection, shoes) during work with the boiler 4.2. Before first use Before starting up the boiler for the first time: 1. Verify correct installation and power system connection of: 4-way valve actuator (if used), central heating pump, DHW and floor heating pump (if used), boiler sensor, fan, feeder. 2. Check the heating system: check tightness, inspect for any leakages from the boiler or the installation, and take special care during servicing of non-insulated components (e.g. doors), which may heat up to high temperatures resulting in risk of burn injuries. Do not stay on the side of the boiler during the opening of the doors and pay attention to flames. Take care of cleanness in the boiler room, ensure proper ventilation and remove corrosive and flammable materials located nearby. The boiler should be cleaned only when it does not work. Use mobile lamps supplied with a voltage lower than 24 V during works connected with servicing of the boiler. Take care of the good condition of the boiler and hydraulic system. Take care of boiler cleanness. check for any frozen water in the pipes and the expansion vessel, control proper and sufficient water level and pressure (depending on the building height, the pressure gauge should indicate 0.8 to 1.5 bar). If water pressure is too low, refill water (only when the boiler is cold). 3. Close the upper inspection door and feeding hopper tightly. 4. Check if the boiler is properly connected to the chimney. 5. Perform chimney draught measurement. 12 Page Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.
4.3. Boiler ignition 1. Switch on the controller (see: Boiler controller operation manual) and activate manual work mode, 2. Check operation of individual devices: fan, feeder, central heating pump activation, 3. Fill the hopper with a proper fuel and close tightly, 4. Switch on the fan. The feeder starts to supply fuel for approx. 2-3 minutes in manual mode. Wait until the fuel appears on the cast-iron burner grate. 5. Ignite fuel using wood chips placed manually on the grate. 6. After ignition, set proper parameters on the controller (boiler operation temperature, feeding time, feeding pause time and blow-in force), according to the values specified in the controller and feeder operation manual. CAUTION! Burner door must be tightly closed in the automatic boiler operation mode. CAUTION! Do not set boiler temperature above 57 C! It increases the possibility of dew point appearance, which accelerates low-temperature corrosion of the heat exchanger. Maintaining water supply temperature below 57 C when using inappropriate solid fuel types leads to intensified boiler wear and lowers the its efficiency. After boiler ignition, entire control of the combustion process is taken by the controller (see. Controller instruction manual) that maintains the set water temperature in the boiler with reference to the heat demand of the building. 4.4. Approximate parameters of the controller The controller is pre-configured, but its input parameters increasing the blow-in force. In the opposite situation, when the change depending on the fuel used and may require individual boiler reaches the set temperature easily or starts to discharge adjustment. Any adjustments shall be made depending on the unburnt fuel, the feeding pause must be extended to provide heat demand, type and quality (calorific value) of coal, or depending on the size of the heating system. reduced accordingly. The blow-in force shall be adjusted based more time for fuel combustion, and the blow-in force must be Setting appropriate parameters ensures economic fuel consumption. The adjustment consists in setting the feeding pause bright-yellow flame. Too weak blow-in force results in red flame on flame observation. Properly adjusted blow-in force gives proper for the heat demand. If the boiler does not reach the set and occurrence of black smoke. Excessive blow-in force results temperature, the feeding pause must be gradually shortened, in short white flame. 4.5. Fuel refilling In order to ensure continuous boiler operation, the hopper must be systematically refilled. In case of fuel shortage, the controller shuts down the entire system and displays a fuel shortage warning. While refilling fuel, switch off the fan using the controller button to prevent smoke backflow to the hopper. CAUTION: During the loading, make sure that fuel is free of impurities that might block the feeder (rubble, stones, wood fragments or metal scrap). 4.6. Boiler stopping Switch off the fan using the controller button, then scrape the heat to the ash pan using the hook supplied along with the boiler.

4.7. Cleaning and maintenance Keeping the boiler clean is necessary for its reliable and faultless operation. Even a thin layer of deposit impairs the recovery of exhaust gas heat, which results in lower boiler efficiency. Accumulated deposit may be the cause of damage to the device. In order to prevent that, the boiler must be thoroughly cleaned at least once in a week. After damping and cooling down of the boiler, remove soot from the combustion chamber and the upper part of the heat exchanger using a wire brush and a scraper. 4.8. Emergency stopping of the boiler Always stop the boiler in any of the following situations: to stop the boiler immediately, remove the heat using a metal 1. water leakage from the boiler, shovel and place it in a metal container. Bring it outside the boiler room and put out with water. 2. temperature increase above 90 C, 3. necessity to refill the evaporated water in the system and CAUTION!
