DESCRIPTION IRON BODY Boiler body made of steel with vertical fumes passages and automatic cleaning system of these passages. In the ducts used for the passage of combustion gases, there are some retainers that favour the exchange of the heat contained in these gases. The impulse and water return intakes (G 1½ ) are in the back of the boiler. The front of the boiler has a large door for access to the combustion chamber and the ash pan for the purpose of cleaning the shoot and removal of ash. There is also an inspection lid placed on the door for the shoot cleaning of the fumes passages. The body is finished with a heat resistant coating to prevent thermal radiations and with the exterior finish of the enclosure sheets to give it cleanliness, pleasant visual aesthetics and protection against burns. BURNER AND FUEL FEEDER The burner has a longitudinal concave shape which receives the fuel to burn from an auger which is fed, in turn and with a hose, by another auger connected to the fuel hopper. There is a ceramic or stainless steel piece (depending on the models) installed over the burner. The air supply is provided by a fan coupled to the burner and supplied with a control for the inflow. The operation of these components is programmed by the electronic control of the boiler. The burner arrangement prevents material from the accumulation of burned material and the risk of a build-up of the burned material. This material is continuously replaced by new one. Burned material does not adhere to the walls of the combustion chamber but is stored in the tray provided for this purpose. Combustion is therefore safe and more notably, due to the characteristics of the material transport lines, heat transfer to the fuel tank becomes impossible. 6

It is possible to operate all its elements for maintenance manually and to adjust the parameters of mode as to achieve the best performance in terms of the fuel used. SAFETY THERMOSTAT Pre-installed in the control panel. It is calibrated at 110 ºC in order to prevent any manoeuvre above this temperature. In case of overheating, it will be activated, and the warning light will be illuminate on in the control panel. It is necessary to wait until the temperature returns to normal to proceed with its rearmament. This is done manually by pressing the button protected by a cap-nut. In the event that the safety thermostat goes off repeatedly, it is imperative to disconnect the boiler and fix the existing fault. PRESSURE GAUGE It measures the pressure of the water in the circuit. FAN It is connected to the outside of the burner. The air intake is controlled by a flap installed in the air entrance of the same. ATTENTION To control it appropriately, consult the electronic regulation manual included with the boiler. ANTI-BACKFIRE FLAME THERMOSTAT It is installed in the feeding tube of the burner and its function is to prevent the backfire of the flame in the burner feeder. THERMOSTATIC FLOOD VALVE It is installed at the top of the auger of the fuel tank and it serves to extinguish the fire by water flooding in case of backfire of the flame in the boiler. 9

SAFETY PRECAUTIONS Please pay attention to the following instructions before the installation and start-up of the boiler. Do not operate the boiler without a proper installation of the chimney. The chimney is very important for the optimum performance of the boiler and must provide the minimum draught in the table of features according to the model of boiler. This must be made of stainless material, thermally insulated and authorised. The boiler must always work on depression. ATTENTION If fumes are produced during the operation of the boiler, ventilate the room and check the tightness of both boiler and chimney elements. Once verified, if the problem persists, contact the T.A.S. for a solution. Installation must be carried out in accordance with the existing laws and regulations for this type of boilers and always taking care and observing the some minimum safety requirements for the people and buildings where they are placed. Existing regulations on fire protection in buildings will be especially considered. Regulations on ventilation, lighting level, electrical safety, minimum dimensions of the room, distance between machines must be complied to facilitate the maintenance as well as protection against external moisture and the provision of an efficient drainage system. The boiler should be installed in a well-ventilated room with a sufficient air entrance. No boiler will be installed in rooms or areas where flammable or explosive products can be stored. Do not install the boiler in spaces or areas of continuous use of people, rooms, living rooms, halls, etc. The boiler must be installed to ensure that the hydraulic circuit incorporates the security measures for an increase of temperature and water pressure, by including an open expansion tank at the highest point of the house or a closed expansion tank with safety valve calibrated to a pressure of 3 bar. Ensure that the water circulating pump in the installation is continuously running, unless it is controlled by a thermostat of minimum temperature of the water of the boiler. Any deficiency in the electrical installation must be repaired. Monitor and regularly maintain the water in the boiler and installation. ATTENTION Do not take water out of the installation or empty the water from the boiler except in extreme cases of maintenance or repair. Under no circumstances should the water from the boiler be for domestic use. Do not fill the body of the boiler with cold water during operation or when the body is hot, it would cause cracks due to thermal contrast cold-hot. The quality of the water is very important. The recommended water hardness is: 1-3 mol/m3= 5.6º d), PH: 8-9.5 10

LOCATION The boiler should be installed to allow easy access for the purpose of cleaning, maintenance and inspections, repairs, etc. It is advisable to support it on a base or a levelled, firm and fire resistant plinth. For a proper combustion, the fuel must be dry. It is recommended to appropriately store it, which will need to be at a safe distance from the boiler (at least 1 m) or in a different room. In no event should it be stored behind the boiler. It will have drainage and sewer connected to the network. The room where the boiler is stored should have continuous and sufficient air inlet. The approximate air consumption of each model of boiler is: BIOSELECT 35 BIOSELECT 50 BIOSELECT 65 120 m 3 /h 160 m 3 /h 208 m 3 /h ATTENTION A drain cock should be installed in the heating circuit, placed in the lowest point and as close to the boiler as possible. The provision of free space around the boiler must be as shown in the below diagram: 11

ASSEMBLY The boiler is supplied in two blocks or packages: the boiler and the burner and, in separate box, the auger feeder, fuel hopper components, enclosures and rest of accessories. BOILER 1. Remove the body boiler from the transport pallet and place it in its final location on the plinth described earlier. 2. Assemble the enclosures (See enclosures parts): 1-2 mm.

Final state: 3. Install the burner with the studs (13) in the location of the rear part of the boiler: 18

Over the burner the ceramic or stainless steel piece (2) that is found in the box: 4. Connect the flue duct to the chimney. The diameter of the chimney must be at least equal to the boiler flue duct and will have the necessary draught as specified in the technical specifications. The mounted chimney will allow its cleaning and/or replacement of a section without having to move the boiler from its position. The exhaust gases from the boiler cannot under any circumstances support the weight of the chimney pipe. The chimney pipe shall be attached to other elements, never to the boiler. 5. Then proceed to complete the rest of the hydraulic installation: - Connect the return pipes with tap to the boiler outlet. - Placement of the fill cock connecting it to the lower pipe (water return). A flap valve must be placed to prevent communication between boiler water and water from the supply when the network pressure drops and the filling valve opens. - Installation of air-traps and safety valve. - Installation of water expansion vessel. - Conduct the safety valve and the discharge pipe to the drainage. - Installation of any other component, in addition to those above, that it is necessary to comply with the existing regulations for this type of installations. TANK / AUGER ATTENTION To place the tank and auger selected, read the biomass transports manual, supplied with the boiler. 19

OPERATING INSTRUCTIONS ATTENTION To control it appropriately, please consult the electronic regulation manual included with the boiler. REGULATION OF THE POWER OPERATING PARAMETERS VALUES The regulation of the power obtained from the boiler is made with the run time parameters and the stop time of the fuel feed. Changing the values of these parameters will result in different fuel consumption. The power must be selected depending on the demand of the installation, thus, once the temperature reaches the selected level, the burner will automatically shut off until such time that the water in the boiler drops below that level. REGULATION OF THE COMBUSTION AIR The combustion air can be regulated by a fan flap. The required flow will mainly vary depending on the power required, i.e., depending on the amount of fuel that is burning; but the specific characteristics of the fuel used (moisture, density, impurities, ) will also have an influence. As a guide, it can be stated that, with a chimney that provides the right draught, the degree of opening of the flap should be: - For maximum power: between 75% and 90%. - For minimum power: between 10% and 20%. Due to major differences that may exist between different fuels, to obtain an optimum air flow it is necessary to verify the correct combustion in the boiler and the gases temperature in the chimney that cannot exceed the values indicated in this manual. 20

IGNITION AND SHUTDOWN Proceed as indicated in the "CONTROL PANEL DIGITAL CONTROL". Before the ignition of the boiler check that the following elements are working properly and are in good condition: Sealing gaskets of the boiler, including front doors, burner plate and connections of the flue duct/chimney. Electronic control and rest of boiler regulation and control elements. Electricity and fuel facilities. Hydraulic installation. Check the operation of the circulator and check that the taps to the output of the boiler are open. Security systems according to the Existing Regulations. Level of water in the boiler. Check that the pressure is of at least 1.5 bar. Then, proceed to the ignition of the boiler: 1. If necessary, clean the combustion chamber, burner and ash collection tray. 2. Fill the fuel tank. 3. Close the doors and allow the fuel in the burner to start to burn (3 5 min.). 4. Once on, switch to automatic mode and the electronic control will start with the operation cycles according to the scheduled times. ATTENTION In the automatic ignition always keep the boiler doors closed to avoid any gas flue or possible deflagration. MAINTENANCE REGULAR INSPECTIONS These inspections may uncover irregularities that could lead to losses in efficiency and/or possible failures in the equipment. Below are examples of operations to be performed during regular inspections: Cleaning of the boiler heat transfer surfaces. Check the values entered into the control programming. Control of burner settings using a combustion analyzer. Check the good condition of the thermal insulation. Verify the absence of: o Fumes (smells), especially toxic. o Leakage of combustible gases (soot deposits/marks). o Noise (excessive or unusual). o Vibration (excessive or unusual). o Water leaks. 21

CLEANING OF THE BOILER Cleaning and maintenance of the boiler and its installation are essential for a proper, clean, economical and safe operation. The combustion chamber and fuel gases passages must be cleaned to remove ash deposits that can damage and reduce the rate of energy combustion transmission to the water. A loss of performance may occur due to an increase in the temperature of the exhaust gases from the boiler. A temperature increase in the gas duct of 100ºC is indicative that it is producing a 5% reduction in boiler efficiency. The user should follow the below recommendations for maintenance and cleaning of the boiler: 1.) To empty the ash tray without turning off the boiler, we need to put the controller in manual mode and take out the tray with protective gloves (thermal). Ashes will be temporarily gathered in a non-combustible container until they are completely off. This container will need to be far away from any combustible material. 2.) It is recommended to empty the tray at least once a week, regardless of the fuel used. 3.) The air intake both from the fan and the auger motors will need to be kept clean. To clean them it is necessary to electrically turn off the boiler. Only employ a DRY brush. It is not recommended the use of any chemicals. 4.) To clean the fumes passage, turn 360º the control located in the upper side of the boiler. You will hear a bang. Repeat this operation several times. It is recommended to do the fumes cleaning at least twice a week. 5.) Once finished any cleaning it is necessary to review all elements of the boiler (hoses, lids and doors seals, connections, connections, etc ) before starting the boiler again. 6.) There is no need to grease the augers, only to clean the motors air inlet. 22
