ENgLIsHtemperatures but checking that it does not drive water in the open expansion tank otherwise it should cause a continuous wateroxygenation with consequent, fast corrosion of boiler body. It must be not to avoid a forced circulation in the open expansion tank.Furthermore it must be electrically connected to a thermostat or a electronic control unit that can be purchased with the thermo-fireplace as OPTIONAL part.8. ANTI-CONDENsATION MIXINg VALVE – (see chapter)ATTENTION: temperature safety sensors must be in place on the machine or at a distance no greater than 30 cm from the flowconnection of the thermo-product. Whenever the thermo products lack a device, those missing can be installed on the thermoproduct flow pipe, within a distance no greater than 1m from the thermo product. All those parts must no have for any reasonmeditate intercept bodies that could accidentally exclude them and must be placed in rooms which are protected from frost. Onthe contrary, if they freeze, the boiler body could break or even explode.ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water; doing thiswould lead to serious damage of the entire structure. The system must be filled by means of the loading pipe directly from theopen tank in a way to prevent an excessive pressure of the water network deforming the body of the thermo heating stove. The system must be kept constantly full of water even during the periods when the use of the thermo-heating stove isn o t requested. During the winter, inactivity must be faced with the addition of antifreeze.CLOsED EXPANsION TANk sYsTEMIt is COMPULsORY that the CLOSED expansion Tank system is provided with:1. A sAFETY VALVE - maximum operation pressure allowed for the system is : see DECLARATION OF PERFORMANCE - CE MARKINGINFORMATION. Higher pressures can cause deformation and breakage of the boiler body. ATTENTION: The inside diameter of thesupply pipe which connects the thermoproduct with the security valve must be equal to the internal diameter of the supply junctionpresent in the thermoproduct. The above mentioned connection pipe must be without siphoning parts.2. ANTI-CONDENsATION MIXINg VALVE – (see chapter)3. AUTOMATIC THERMAL DIsCHARgE VALVE DsA or TEMPERATURE sAFETY RELIEF VALVE, with double safety sensor4. CLOsED EXPANsION Tank can be installed on the thermo product return pipe. ATTENTION: The inside diameter of the return pipewhich connects the thermoproduct with the closed expansion vessel must be equal to the internal diameter of the return junctionpresent in the thermoproduct. The above mentioned connection pipe must be without siphoning parts.5. PUMP CONTROL THERMOsTAT6. NOIsE ALARM ACTIVATION THERMOsTAT7. NOIsE ALARM8. TEMPERATURE INDICATOR9. PREssURE INDICATOR10. PUMP sYsTEMATTENTION: temperature safety sensors must be in place on the machine or at a distance no greater than 30 cm from the flowconnection of the thermo-product. Whenever the thermo products lack a device, those missing can be installed on the thermoproduct flow pipe, within a distance no greater than 1m from the thermo product.. All those parts must no have for any reasonmeditate intercept bodies that could accidentally exclude them and must be placed in rooms which are protected from frost. Onthe contrary, if they freeze, the boiler body could break or even explode.IT Is MANDATORY that the thermo products for domestic heating inserted in CLOsED Tank heating systems, must be internally equipped,with a cooling circuit, prepared by the unit manufacturer, which is activated by a thermal safety valve (see chapter VAsT) which does notrequire auxiliary power and can guarantee that the standard set temperature limit is not exceeded. Connection between the power supplyunit and the valve must be free from interceptions. Cooling circuit upstream pressure must be at least 1,5 bar.VMA - ANTI-CONDENsATION MIXINg VALVE - IT Is MANDATORY (PURCHASED AS OPTIONAL)The Anti-condensation mixing valve finds applications in solid fuel heat generators as it prevents cold water return in the exchanger. Routes1 and 3 are always open and, along with the pump installed on the return (R), they guarantee water circulation inside the biomass boilerexchanger (CB- chapter INSTALLATION LAy-OUT). An elevated return temperature, allows efficiency improvement, reduces formation ofsmoke condensation and prolongs the boiler life span.Valves on the market have different calibrations. La NORDICA advises use of model 55°c with 1” hydraulic connections. Once the valvecalibration temperature is reached, route 2 opens and the boiler water goes to the system via the flow (M). IMPORTANT lack of installation of the device voids the heat exchanger warranty.VAsT - AUTOMATIC THERMAL DIsCHARgE VALVE DsA - (PURCHASED AS OPTIONAL)Solid fuel thermo products must be installed with safety devices determined by laws in vigour.For this reason the thermo products is equipped with a heat discharge coil.The heat discharge coil must have one side connected to the water network (chapter INSTALLATION LAy-OUT - chap. DIMENSION SHEET- A) and the other rot drainage network (C). When the safety temperature is reached, the automatic thermal discharge valve DSA, the bulb ofwhich is to be connected to attachment B, enables the intake of cold water in the boiler coil, discharging the excess heat out of pipe C towards24
