SA FETY For safety reasons, remember that: The use the boiler by people (including children) with no experience or with reduced physical and mental capacity, if not supervised and are not guided in the use of the appliance by a person responsible for their safety, is not permitted. You should check and make sure children do not play with the appliance. Do not touch the boiler when barefoot or with wet and moist areas of the body. Do not modify safety equipment or settings without the permission or the manufacturer's instructions. Do not pull, do not turn and cut off the electrical wires protruding from the boiler even if it is disconnected from the network. We recommend that you put the power supply cable in place not in contact with the hot parts of the appliance. The supply plug must be accessible after installation. Avoid closing or reducing the size of ventilation openings at the installation site, the vents are necessary for proper combustion. Do not let the elements of the package near children. During the normal operation of the product all doors and lids should always remain tightly closed. When the device works it is warm to the touch, especially the external surfaces. We advise you to use in caution. 3

Check for obstructions before turning on the device if it has been out of operation for a long time. In case of particularly adverse weather conditions (strong wind, frost) it is likely that safety systems intervene and turn off the boiler. If this happens please contact technical support and NEVER disable safety devices. In case of fire in the flue way obtain the means to suppress the flames or seek the intervention of the fire service. This device should not be used for burning wastes. Do not use flammable liquids for ignition. When filling, do not bring your pellet sack in contact with the product. 3. INSTALLATION 3.1 RES PONS I BI LIT Y OF T HE INST ALLE R Responsibility of the installer is to perform inspections of fluepipes, air inlet and all the electrical and hydraulic solutions required for your pellet boiler. Responsibility of the installer is also to ensure compliance with current special local laws where the boiler is installed. The use of the pellet boiler should take place in compliance with the directions given by this document and by all maintenance and safety standards in line with current special legislation, valid where the boiler is installed. According to the standards that define the obligations of installer, the installer should confirm: The type of the installed unit The compatibility of the installation space with the unit, expressed as minimum volume installation according to the manufacturer's instructions. The instructions of the boiler manufacturer regarding the conditions of smoke removal system (fluepipes or flueways). The internal cross section of the stack, the material of which it has been constructed, equal crosssectional dimensions, lack of obstructions. The height and vertical extension of the chimney. The height above sea level at the site. The existence and adequacy of watertight closure. The capacity of external air inlets and the sizes of existing ones. The possibility of parallel use of the generator system with pre existing other equipment. If the results of all tests are positive, the installation can proceed. Carefully observe the instructions provided by the manufacturer and current safety and fire safety standards. Once installation is complete, the system should be tested for no less than 60 minutes for all functions to be checked. Once the installation and trial operation are completed, the installer should provide the customer with the following: The use and maintenance form of the unit as supplied by the manufacturer (if not already provided with the unit) The required documentation for compliance with the current standards. 3.2 PERMITTED INSTA LL ATIONS At the location where the boiler is installed, may already exist, or may be established only devices that pose no recession in space in relation to the external environment. 4

3.3 NO N- PERM ITTED INSTA LLA TIONS MEGATRON 25 & 35 In the area where you need to install the boiler must not already exist or be installed: Hood with gas suction. Ventilation ducts with gas suction. If these devices exist in areas adjacent to the installation site, the simultaneous use of the boiler is permitted because of the risk that one of the two areas falls into recession. 3.4 C HI MNEY To assemble the stack non flammable materials must be used suitable to withstand the combustion products and any condensation. The use of flexible metal tubes and fiber cement to connect the flue of the boiler is prohibited. The chimney must not cross areas where installation of combustion appliances is prohibited. The placement of the chimney should be done in such a way as to ensure the operating conditions of the device, to reduce the formation of condensate and avoid their transfer to the device. the placement of horizontal sections should be avoided as much as possible (allowable limit 3m). Fig. 1 For devices that must reach the top or the wall the direction changes must be made with open elbows no more than 45 or angled 90 (no more than 3 in total). The use of reverse inclination components is prohibited. It is recommended that the chimney has a collection chamber for solid materials and any condensate, located below the inlet of smoke pipe, so that it can easily be opened and inspected (Fig. 2). It is forbidden for other air ducts and piping to pass inside the smoke pipe, even if it is of large size. It must be properly spaced from combustible materials through am insulating layer of air or proper insulation (Fig. 3, 4, Table 1). The chimney must accept the discharge from a single boiler. The direct indoors discharge is prohibited even in rooms with open ceiling. Fig. 2 Fig. 3 Fig. 4 5

The draught of the chimney must be 10 15 Pa!!! Fig. 5 Fig. 6 3.5 C HI MNEY EN D The chimney end must meet the following requirements: have inner section equal to that of the stack. have useful outlet section not less than twice that of the interior of the chimney. be constructed in such a way as to prevent the penetration of rain, snow, foreign bodies in the chimney, and to guarantee the discharge of combustion products even in case of winds of any direction and inclination. be positioned in such a way as to ensure proper dispersion and dissolution of the combustion products and certainly outside the regression area where the formation of opposite pressures is favored, such area has different sizes and configurations depending on the tilt angle of the cover. The end of the stack must have no mechanical suction. 6

3.6 INS U LATION, FINISH, COATING AND SAFETY RECOMMENDATIONS MEGATRON 25 & 35 The coatings regardless of the material they are made must be a self supporting structure with respect to the heated system and should not be in contact with it. Beams and finishes of wood or flammable sufficiently insulated. materials must be placed outside the radiation area of the boiler or be If covers made of flammable or heat sensitive material exist in the space above the boiler, a protective barrier of insulating or non combustible material should be placed. Components made of combustible or flammable material such as wooden furniture, curtains, etc. that are directly exposed to the radiation of the fire should be placed at a safe distance. The device installation must guarantee easy access for cleaning the device itself, pipelines and gas discharge pipes. 3. 7 H YDRA U LIC CONN ECTION This appliance has been designed to heat water for a hot water type heating system. When the appliance is operating regularly it produces hot water at a temperature that is necessarily below boiling point and a heating system must therefore be designed that is suited to the characteristics of the appliance. A qualified heating plumber must be called in to: check an existing heating installation. design, install and check a new heating installation. The water heating system must be sized in relation to the average power of the appliance and the heating requirements of the building (see TECHNICAL DATA ). The fittings for connecting the appliance to the plumbing system are to be found at the rear. Connections: Connect the appliance to the heating plumbing system (supply return) using pipe unions and stop valves facilitate any future maintenance or draining of the heating system. Should the temperature/pressure relief valve activate, the water must be free to flow away without causing injury to person, damage to property or to the electrical parts of the boiler. Installing shut-off valves on the inlet and the outlet enable maintenance to be carried out without having to drain the system. Drain taps inserted in the lowest points of the system make it easier to drain the system if necessary. Air valves installed at all the highest points of the system make it easier to bleed the heating system. Do not install thermostats on all the heaters (radiators) of the heating system so that at least the minimum output of the appliance can be dissipated. Use sections of hose to connect the boiler so that it can be moved slightly (check that any kinks in the hose do not allow air pockets to form). Install a manometer near the appliance delivery or return fittings to check the working pressure of the system. Connect the appliance pressure/temperature relief valve to a suitable drip funnel to take away water at high pressure and temperature. Avoid any narrowing in the diameter of the pipe work. Avoid using elbows or bends with a small radius. Provide adequate supports for the water pipes so that they do not weigh on the fittings of the unit. Before connecting the appliance, flush the heating system through to eliminate any residues (oil, swarm, drops of weld material, hemp, rust) inside the pipe work, which could otherwise damage the boiler or cause malfunction. Insulate the connecting pipe work adequately to prevent heat loss and the formation of condensation. Under no circumstances light the appliance unless the water circuit is completely filled with water. to 7

HYDRAULIC DIAGRAM MEGATRON 25 & 35 3.8 NATI ONA L, REGIONA L, PRO VI NSIONA L AND LOCAL REGULATIONS It is also necessary to keep in mind all national, regional, provincial and municipal laws and regulations of the country in which the device is installed. 4. PELLET AN D PE LL ET LOA DING ATTENTION!!! THE USE OF PELLETS NOT IN ACCORDANCE WITH THE STANDARDS, AND THE USE OF OTHER COMBUSTIBLE MATERIAL, HARMS THE PROPER FUNCTION OF YOUR PRODUCT AND MAY VOID THE WARRANTEE AND THE ATTACHED MANUFACTURER S RESPONSIBILITY. 4.1 PELLET Q UA LIT Y The pellet boiler is designed to use compressed wood pellets. Since the market has many products of this type, it is important to choose pellet with high standards. The link to the burning compressed wood has established a model for that fuel product. Be sure to use quality pellet that is compact and has low concentration of dust. Ask your dealer for the appropriate pellet, the diameter of which should be 6mm and its length about 30mm. The proper functioning of the pellet boiler depends on the type and quality of the pellet used, and the heat generated by the different types of products can have varying degrees of efficiency. We recommend pellet with specifications according to ÖNORM M1735, DIN plus EN 14961. The manufacturer shall not be liable for the use of low quality pellet and for the resulting improper function of the boiler. To ensure smooth operation, you must: Avoid using pellets with dimensions different from those provided by the manufacturer. Avoid using pellets, containing saw dust, bark, corn, resins or chemicals (additives, adhesives) Avoid using wet pellets. Avoid using pellets that produce other residuals except ashes after burning. 8

Using unsuitable pellets causes: Obstructions of the burner and flue way. Reduction in efficiency. Excessive dirt on the protective glass Unburned grains and heavy ash.

With the return of the supply voltage, the system evaluates the saved data and: If the outage is less than 60 s the system returns to the state in which it was previously If the system was in a On state and the outage of voltage is less than 50 min and greater than 60 s, the system goes in Recover Ignition In case of prolonged absence of Supply Voltage the system goes in Block with error message Er15. 6. CONNECTIONS 6.1 T HERMOSTAT CONNECTION The room thermostat is connected to two pink wires on the back of the boiler. This connection should serve as a simple switch on / off (cold junction). It gives neither requires power. (If the thermostat you want to use gives power, drive it through an external relay and get cold touch on / off from the relay). Attention: The inlet of the thermostat is a clean contact, with zero potential. For this reason, it should connected to any voltage element. not be Function of the room thermostat The system is set so that when the room temperature reaches the thermostat set value, the boiler goes to the Modulation operation state. 6.2 C HECKING T HE CO RR ECT CONNECTIONS OF T HE T HERMOSTAT To check the correct connection and operation of the thermostat it is enough to turn it off and then observe a black line next to the thermostat symbol on the control display. Instead, the black line turns off when the thermostat is on. 6.3 S UPP LY CON NECTION There is a power cable provided with the boiler. Plug the power cord into the slots on the back of the boiler and the other side in an earthed socket. DO NOT CONNECT THE BOILER WITH A POWER CABLE WITHOUT USING GROUND. IMPORTANT Use uninterruptible power supply system (U.P.S. uninterruptible pure sine wave power supplies 500W minimum) to avoid problems in case of power outage. Damage due to power outages or large fluctuations in voltage is not covered by warranty. 22

MAINTENANCE Under current legislation on safety of electrical appliances for all installation operations, maintenance or repairs that require access to the interior of the boiler or gas chamber should be directed to a service center or qualified service personnel. The required actions of regular maintenance considered mandatory to ensure the smooth and efficient operation. If these actions do not run with the expected frequency, the device performance can drop significantly. The manufacturer assumes no responsibility for reducing performance or malfunctions due to poor maintenance. All maintenance activities (cleaning, replacements, etc.) must be performed after the device is switched off, cooled down and unplugged from the power supply. Do not use materials that could scratch or corrode glass. The scratches could be converted into cracks or breaks. A damp cloth is sufficient. Furthermore, do not use any abrasive cleaners. The instructions provided below are purely indicative. The frequency of these operations depends on how hard the boiler is used and the quality of the pellet used. Any cleaning or maintenance work must be carried out with the appliance disconnected from the power supply. 24

8.1 C O MB USTION CONTAINER Every day before every start, the chamber should be cleaned: Detach the container out of the slot. Clean the ash and any accumulated tartar. Thoroughly clean the holes of the container with a sharp object. Check the reception of the container and remove any ash Before turning on the device, make sure the container is properly positioned into the slot and shifted backwards to touch the resistance tube. Fig. 20 8.2 AS HP AN Every 2 3 days before the start, you should clean the ash pan: Open the lower ash pan door of the boiler. Empty the ash pan into a metal trash can. Tightly close the lower ash pan door of the boiler Fig. 21 8.3 COMBUSTION CHAMBER AND TUBES Every month or so (or after burning 2 tons of pellets) the combustion chamber and the tubes present therein should be cleaned. The clean tubes favour the better operation of the device and maximize performance. For the above mentioned cleaning process you may have to obtain a vacuum cleaner specific for ash as well as a brush for cleaning the pipes. Proceed as follows: Fig. 22 Unclip the upper boiler cover (Fig. 22). Unscrew the top cover of the boiler (Fig. 23). Remove the cleaning lever and the flue gas retarder. Remove with a vacuum cleaner the ash that has accumulated Scrape the tubes with the brush (Fig. 24). Fig. 23 Clean the removed parts and assemble them again in the reverse order. Open the front flame inspection door (the one with the window) (Fig. 25). Fig. 24 25

With the vacuum suck (or scrape with a spatula) the ashes and debris accumulated in the side walls and the upper side of the hearth MEGATRON 25 & 35 Close tightly the door. Unscrew the side cover. Unscrew the two screws and remove the door (Fig. 25a). Use a brush to clean the accumulated ash (Fig. 25b). Fig. 25 Fig. 25a Assemble the removed parts again in the reverse order Attention: For the 25 / 35 kw model move up and down 4 5 times the lever for cleaning the pipes every 2 3 days and when the boiler is off. (Fig. 26). g Fig. 25 b Fig. 26 8.4 C LE A NING OF T HE F LUEGAS E XHA UST SYSTEM Every month we recommend you to perform this maintenance at least once. Remove the cap of the T fitting and clean the fluepipes. Clean the removed parts and assemble them again, In the reverse order. Fig. 27 8.5 C LE A NING OF FLUEGAS FAN The boiler has an exhaust fan at the rear side. The excessive accumulation of ash or dust on the impeller of the fan causes loss of balance and therefore excessive noise during the operation. For this reason, you should clean the fan at least once a year. In order to perform the cleaning some parts of the device must be dismantled, we recommend that you call technical support or a qualified technician. 8.6 C LE A NING FOR NON- OPERATION PE RI O D At the end of the usage period of the boiler, you must do the following: Remove all pellets from the container and the auger. Thoroughly clean the burner, the burner slot and the ash drawer. Clean with a wire the interior of the combustion chamber. Thoroughly clean the fluepipes. We recommend that you assign the cleaning to a professional chimney sweep. Clean once a year (dust, spiders, etc.) the gap between covers. Unplug the power cord from the power supply. 26

EVERY TIME the scheduled maintenance must be performed and before the turning on of the device, after a long period of inactivity. The following actions are necessary for the smooth and safe operation of the device. Thorough cleaning of exhaust chamber (see section "CLEANING EXHAUST CHAMBER AND BOILER"). Check and clean the exhaust system. Clean dust and spiders that may exist in the internal side of the covers. Cleaning of moving parts and mechanisms. Checking of electrical, electronic and hydraulic parts. Check the water level and pressure of hydraulic system. Possibly restore normal values and bleed radiators. Check that the impeller of the pump is in good condition. If it is blocked, unscrew the cap of the pump with a screwdriver and unblock it. Check the seals of the glass for leaks and damage, the hydraulic circuit and all items that may be worn, and replace any worn items. Check the tightness of unions and piping connections. Check the condition of the thermal protection and safety valve (relief), if activated. Make sure they are operating properly. Otherwise, replace them. Perform all maintenance actions and control measures required for the proper operation and compliance with safety rules. Turn on the boiler once, according to the instructions under "TURNING ON THE BOILER". Any cleaning and / or maintenance should be done with the device disconnected from the power supply. 27
