    2. THE PURPOSE OF THIS MANUAL The purpose of the instructions is to enable the user to take all the necessary measures in order to ensure safe and proper use of the stove. 2.1 UPDATES This manual reflects a work of art at the moment when the boiler was placed on the market. Therefore, producer does not take into account the boilers that are already on the market with the appropriate technical documentation and considers them as defective or inadequate after any kind of modification, adaptation or application of new technologies to newly produced machines.

    3.2 TRANSPORTING AND MOVING THE BOILER - HANDLING When moving the boiler, it is necessary to be careful and not allow the boiler to tilt forward. This is because the brunt of the stove is forward. During transportation of the stove, which has to be completely safe, make sure that the forklift has the load that is greater than the weight of the stove that it is supposed to lift.

  • Page 11: The Smoke Exhaust System

    ATTENTION! If the ejection path of smoke creates such a bad draft, of a bad flow of air (many curves, improper completion of the ejection of smoke, constriction, etc.) discharge of smoke can be bad, or in a situation like this smoke discharging is not as good as it could be. The smoke ejection system from the boiler operates under negative pressure in the stove chamber and with mild pressure from the smoke drain pipe.

  • Page 14 Figure 4a. Cleaning elements Ideal vacuum primarily depends on the absence of barriers such as narrowing and/or corner connectors. It is recommended that the knees are 30°, 45 °, and 90 °. Knee at 90 ° shall be three-fold (Figure 4b). In any case, it is necessary to ensure that the initial part of the vertical flue pipe has the length of at least 1.5 m.

    INSULATION AND THE DIAMETER OF THE OPENING (HOLE) ON THE ROOF (OR IN THE WALL) Once you determine the position of the boiler, it is necessary to make a hole through which a smoke pipe must pass. This varies depending on the type of installation, diameter of the exhaust gas pipe (see Table 1) and the type of wall or roof for the tube to pass.

  • Page 18: Commbustion Air Supply

    4.4 COMMBUSTION AIR SUPPLY The air required for combustion, which is taken from the environment, must be supplied by a single ventilation grill mounted on the outer wall of the room. This will ensure better combustion and thus lower consumption of pellets. It is not recommended to have outside air drawn directly from the tube, as it will reduce the efficiency of combustion.
  • Page 19: Connecting The Power

    4.5 CONNECTING THE POWER These stoves are connected to electricity. Our stoves have electrical cables that are suitable for medium temperature. If you need to replace the power cord (if it is damaged, for example) then consult with our authorized technical staff. Before you plug in the electric stove note the following: - That the characteristics of electrical systems correspond to the information that is specified in the data on the identification plate on the boiler.
  • Page 20: Warning Safety Measures For Staff

    The stove operates with a combustion chamber, which is in the negative pressure. Therefore, make sure that the smoke is well thermally insulated. When the stove is turned on for the first time then, due to the stabilization process a small amount of paint (not harmful to health) that covers the stove vaporizes.
  • Page 21: Warning Safety Measures For The User

    6.1 WARNING SAFETY MEASURES FOR THE USER The place where the boiler is to be set up, called the mounting place, must be prepared by local, national, and European regulations. The boiler is a “heating machine" and while it is on it has outer surfaces that are very hot or that achieve very high temperatures.
  • Page 22 Use a drum shaped vacuum cleaner that can facilitate cleaning the boiler. The vacuum cleaner must have a filter that will prevent the sucked dust to go back into the room where the boiler is located. Before you get started with routine maintenance, including cleaning, take the following precautions: •...

Upper ash container must be cleaned every or every other day, by vacuuming or by simple throwing the ashes away.
  • Page 25 They need to be cleaned manually with a special key for every 150-180 kg of spent pellets (two full tank of pellet). First use the key to lift up small round lids with openings, two of them, that are located on the cover of the stove at the top.
  • Page 26 7.2 CLEANING AND MAINTENANCE (for employees who do maintenance) FLUES - CHIMNEY should be cleaned every six months or after burning two tons of pellets. Make sure the stove and the ash are cold. The smoke channel (chimney) is resistant to wind and has to be checked and cleaned every year, best at the beginning of the heating season.
  • Page 27: Special Maintenance

    7.3 SPECIAL MAINTENANCE Your boiler is a heat generator that uses pellets as solid biofuel. This is why you should do special maintenance once a year. This is best done at the beginning of the heating season. The purpose of the special maintenance is to ensure proper and efficient operation of the boiler. 8.
  • Page 28: Storing The Pellet

    9.1 STORING THE PELLET The pellets must be kept in a dry place that is not very cold. Cold and moist pellets (at the temperature of around 5 C) reduce the thermal power of the fuel and require additional cleaning of the boiler. THE PELLETS MUST NOT BE KEPT CLOSE TO THE BOILER.
  • Page 29 IMPORTANT: Connecting the stove on a hydraulic installation can be done exclusively by qualified technicians, who can do this in accordance with applicable regulations of the country in which the installation is done. Producer disclaims all liability in case of a material or bodily harm, in the event of failure, poor functioning, if the above recommendations are not followed.
  • Page 30: Pressure And Return Pipe

    Figure 22. 11. PRESSURE AND RETURN PIPE Outputs of the pressure and return pipes on the boiler are 1'' and you cannot reduce them or taper to the first bifurcation. Use a 1’’ steel pipe or a copper pipe with the outside diameter of Ø28mm or greater. When installing, strictly observe the slopes of pipes as they need to be at 0.5% (5mm.

    12. BUILT-IN COMPONENT OF THE BOILER Note: If the boiler and the pump have been idle for a long time (a month, for example), the pipe shaft can stick to the base, it may not move the water, or it can burn out. If when starting the boiler when the water in the boiler heats up the water pump does not start, if the radiators do not heat up when the set temperature is reached, if you do not hear the murmur of water (moving), or if the boiler temperature rises and radiators are not warming, remove the left lateral side as indicated in the previous paragraph, and get to the pump.

    12.1 AUTOMATIC AiR VALVE Figure 23. The cap valve must be loose, not tight, so that the air can come out of the boiler and installations smoothly. The boiler must be full with water without air. With the first charging system in the boiler and every year before the start of the heating season all air from the system needs to be removed.
  • Page 33: Installing And Igniting

    13. INSTALLING AND IGNITING Before boiler start up, the system must be filled with water and free from air bubbles. Chimney must be connected as described in previous chapters. System must be filled with cold water up to the pressure between 1 to 1.5bar (cold water pressure). The boiler has internal pressure valve protection that opens at 3 bars.
