AIRTIGHT GAS-FIRED RADIANT TUBES INFRA1 GENERAL RULESSYSTEMA S.p.A.This instructions booklet is an integral part and essential of the appliance and must be kept with care near the appliancefor all future consultation.Read the instructions and warnings in this booklet carefully, as they supply important indications for safety, installation,use and maintenance.ATTENTION !!If you lose this booklet, contact the manufacturer immediately.The appliance has been built for heating large work environments such as industrial and handicrafts sheds in general,warehouses, premises with large-scale air renewal, loading bays outside sheds, environments for sports activities(gymnasiums), by means of the principle of thermal radiation; this allows the heating of single specific area and, if suitablycombined with other appliances, heating of the whole environment. It may be used for heating premises for zootechnicaluses (poultry and swine farms) and for agriculture (greenhouses) and in all those industrial production cycles(ovens) in which heating is needed without there being any contact between the product and the combustion fumes.It is not allowed to use the appliance to heat premises intended for handicraft or industrial activities in which the processescarried out and the materials stored involve a risk of the formation of gas, vapours or dust which could causefire or explosions.The appliance must be installed by professionally qualified personnel, responsible for compliance with the safety regulationsin force. The manufacturer declines all responsibility in the event of damage due to incorrect installation or toimproper and/or incorrect use of the appliance.The packing material (nylon, polystyrene foam, wood, staples, etc.) must not be left within the reach of children, as theyare potential hazards.The appliance must be started up for the first time by qualified personnel.In the event of stopping and/or malfunction of the appliance, switch it off. Any repairs or replacement of componentsmust be carried out exclusively by skilled personnel, using only original spare parts. Failure to abide by these rulesmay be detrimental to the safety of the appliance.To guarantee good operation of the appliance it is indispensable to follow scrupulously the indications given by themanufacturer and to have maintenance carried out on the appliance by skilled personnel (at least once a year).2 PACKING2.1 Packing lista) The exhaust fan and burner are each seperatlypacked in a card board box, complete with theinstallation and operating manual.b) We also further pack all remaing components, to fitreflecting canopie, in a card board box.c) The varius sizes of radiant tubes required for eachof our Infra radiant heaters, is separatly packed withall the necessary manifolds and sleeves to completethe heater.e) The reflecting hoods are supplied packed one ontop of the other (minimum bulk). As an alternative tothe standard hoods, it is possible to have type RBThoods (see detail, fig. 11) with top insulation of rockwool, or maxi hoods with their own support brackets(see fig. 10).f) End pieces for the air and fumes ducts: these aresupplied in various models and versions dependingon the final applications; normal versions on thewall or ceiling with flashing, coaxial on the wall orceiling, both wrapped in protective nylon film. ATTENTION !! Remove any protective plastic film from the hoods before fitting them onto the brackets.5Rev. 18GB0610

AIRTIGHT GAS-FIRED RADIANT TUBES INFRA3 GENERAL TECHNICAL CHARACTERISTICSSYSTEMA S.p.A.3.1 Description and characteristics of operationThe “INFRA” airtight gas-fired radiant tubes is made of a pickled stainless steel tube, in a U shape, inside which takesplace the combustion of a gaseous component (natural gas, LPG.), bringing the outside surface to an average temperatureof about 350°C. The steady operation temperature is reached in a few minutes. The control, mixing, combustionand ignition are enclosed in an airtight container, installed in the head of each module. Since the air intake ductand the fume expulsion duct are continuously connected from the head of the module to the outside of the building,there is no communication between the combustion chamber and the inside environment; this fact guarantees maximumsafety. Above the whole length (6, 9, 12 m) of the radiating tube there is a mirror surface, with the purpose ofreflecting down the heat radiation produced by the tube itself. This surface may also be provided with rock wool insulationon the top part (the so-called RBT version). The control of the conditions of comfort inside the environment isassigned to the infrared-sensitive thermostats located in the immediate vicinity of the work area and placed on an electricpanel which can switch on and off one or more modules at the same time. This offers the possibility of heating eitherthe whole environment or individual areas, even at different temperatures.Fig. 1a Packing of theRBT hoods11= Bag containing split pins and washer2= Pads of rock wool (in packs of 20 pieces)3= Mirror reflecting hoods4= Top protection hoods23 4Fig. 1b Assembly of theRBT hoodsC1) Place the pad (D) on top of the reflectinghood (E).2) Place the top hood (C) on top of thepad and the reflecting hood.3) Secure the parts with the split pinsthrough the central holes (B).4) Join the hoods together, securing oneto another by inserting the clip in theoutside holes (A).DAB1EAB27Rev. 18GB0610

Laboratory experiments have shown that combustible materials (with a surface of 0.5 m 2 ), placedat a distance of 1.5 metres from the module and parallel to it, never reach temperatures that could be considereddangerous. In particular cases, if it is impossible to respect these distances (for example motors of the carriages on abridge crane, electric cables, lamps, cabins) suitable steps must be taken to screen heat-susceptible materials from themodule heat radiation (see fig. 16).600mm (with normal hood)200mm (with RBT hood)(*)MINIMUM DISTANCES OF COMBUSTIBLE MATE-RIALS FROM THE HEAT RADIATING TUBE(wood, cardboard, plastic materials, pallets, etc.)ACCORDING TO:- STANDARD DIN 3372 part 6, par. 3.12- DVGW, G63/11, part 12/3.1.2In any case the distance must be such that the maximumsurface temperature of the materials does notexceed 85°C.The bearing elements must not be heated on large surfacesto over 50°C.(*)Combustible materialFloorFig. 15 Distance from combustible materialCoverageModulo radiante INFRAEletric motorInsulation (rock wool 3cm thick minimum)Protecyive plate (stainless steel, galvanisedplate, aluminium)must allow air passage for ventilating the motorBRIDGE CRANEFig. 16 Example of protection of the motor of a bridge crane23Rev. 18GB0610

AIRTIGHT GAS-FIRED RADIANT TUBES INFRA7 GAS PIPESYSTEMA S.p.A.The gas supply pipe must be made in compliance with the standards in force in the country in which the plant is installed.The dimensions of the pipes and of any pressure reducers must be such as to guarantee the correct operation of theappliances. The materials used must comply with the standards in force in the country in which the plant is installed.7.1 Connecting the applianceThe appliance must be connected to the main pipe with a flexible coupling so as not to hamper oscillation of the appliancedue to expansion.Scaling on thread of nipple (A) must be assured by a specific product, guaranteed by its manufacturer for use with thespecific gas utilized in the installation. The use of white lead paint or minium paint has to be absolutely excluded.3/4 ball valve3/4 stainlesssteel couplingMain pipeAOscillationFig. 42 Connection to the main pipe with a 3/4 flexible stainless steel coupling (minimum length 30 cm)3/4 ball valveFlexible coppertube Ø 16 mmMain pipeOscillationFig. 43 Connection to the main pipe with a 16 mm flexible copper tube41Rev. 18GB0610

SYSTEMA S.p.A.AIRTIGHT GAS-FIRED RADIANT TUBES INFRAa) For Natural gas G20: upstream on the main line, after the counter, always install a pressure stabilizer and a pressuregauge with scale 0÷60 mbar (0.06 bar) and regulate the pressure at 20 mbar (0.02 bar); a higher pressuremay create bad combustion, difficulty in lighting the flame and holes in the radiating pipes due to excessive temperature.b) For LPG (G31): near the tank it is indispensable to install a “1st stage” pressure reducer so as to reduce the pressureto 1.5 bar; on the main external line in the shed, always install a “2nd stage” pressure reducer to reduce thepressure as indicated in the table on page 50. A higher pressure may create bad combustion, difficulty in lightingthe flame and holes in the radiating pipes due to excessive temperature.c) Upstream and downstream from the main gas supply line it is advisable to install a pressure gauge in a visible positionwith scale 0÷60 mbar (0.06 bar) so as to see any difference in pressure upstream and downstream and thereforethe capacity of the whole network.d) Regulating the gas supply pressure: all the appliances are tested and calibrated in the factory for the pressures forwhich they are intended (see data plate on the burner).To check the burner pressure (Natural gas G20), use the pressure outlet indicated in point 2 (fig. 55) at the outlet of theelectrovalve after having removed the closing screw; if the pressure values in the burner do not correspond, calibrationmust be performed (with the burner operating) by turning the pressure regulating screw indicated in point 3 (fig. 55) onthe side of the valve until the rated value is obtained.IMPORTANT: please seal the adjustment device of the gas valve after completing adjustmentIMPORTANTFor Natural gas supply with pressures higher than 20 mbar (approx. 200 mm), always provide apressure stabilizer for each appliance and regulate the pressure at 20 mbar.For LPG gas (Butan-Propane G30-G31), the regulator for the solenoid has been excluded. To carry out this operationthe pressure regulator with the valve, indicated at number 3 (see fig. 55) has to be completely closed. To check thepower supply pressure use the pressure tube postioned in the solenoid valve entry (with the burner operating), indicatedat number 4 (see fig. 55). If the output of the power is not sufficient, it will be necessary to proceed with a setting(Burner operating) on the pressure regulator positioned on the top of the system (valve).At the end of the above pressure-regulating operations, always remember to close the pressure outlets on the electrovalvewith the screws provided.IMPORTANT: please seal the adjustment device of the gas valve after completing adjustmentRev. 18GB061042
