Hoval BioLyt (50-70)EngineeringStandards and guidelinesThe following standards and guidelines mustbe complied with:- Hoval technical information and installationinstructions.- Hydraulic and technical control regulations.- Local fire regulations as well as national regulations.- VKF fire protection regulations.- Regulations SWKI 97-1 „Water condition forheating, steam, cooling and air conditioningapparatus”.- Regulations SWK1.91-1 Ventilation and extractionof heating area.- Regulations SWK1-93-1 „Safety engineeringequipment for heating apparatus”.- Pay attention to SIA recommendationsNumber 384/4 „Chimneys for building heating,cross section identification”.- Regulations Procal/FKR “Plug in electricalconnections on boilers and burners“.- Instruction leaflet –Procal „Corrosion throughhalogen connections“.- Procal instruction leaflet concerning „Corrosion damage in heating apparatus“ and brochure“Corrosion and boiler scale protectionin heating and service water installations”.- The LRV regulations must be adhered to.- Requirements for pellets in line with DIN/SN,Swisspellet, ÖNORM and PVA (PelletsverbandAustria).Water qualityHeating water:- The European Standard EN 14868 and theDirective VDI 2035 must be observed. Inparticular, attention must be paid to the followingstipulations:-- Hoval boilers and calorifiers are designedfor heating plants without significant oxygenintake (plant type I according to EN 14868).-- Plants with--continuous oxygen intake (e.g. underfloorheating systems without diffusion proofplastic piping) or--intermittent oxygen intake (e.g. wherefre quent refilling is necessary)must be equipped with separate circuits.-- Treated heating water must be tested atleast 1 x yearly. According to the inhibitorma nufacturer‘s instructions, more frequenttest ing may be necessary.Table 1: Maximal filling quantity based on VDI 2035-- A refilling is not necessary if the quality ofthe heating water in existing installations(e.g. exchange of boiler) conforms to VDI2035. The Directive VDI 2035 applies equallyto the replacement water.- New and if applicable existing installationsneed to be adequately cleaned and flushedbefore being filled. The boiler may only be filledafter the heating system has been flushed!- Parts of the boiler which have contact withwater are made of ferrous materials.- On account of the danger of stress crackingcorrosion the chloride, nitrate and sulphatecontents of the heating water must not exceed200 mg/l in total..- The pH value of the heating water shouldlie between 8.3 and 9.5 after 6 -12 weeks ofheating operation.Filling and replacement water:-- For a plant using Hoval boilers untreateddrink ing water is generally best suited asheat ing medium, i.e. as filling and replacementwater. However, the water quality ofthe untreated drinking water must ful fil thestandard set in VDI 2035. Should the mainswater available not be suited for use then itmust be desalinated and/ or be treated withinhibitors. The stipulations of EN 14868 mustbe observed.-- In order to maintain a high level of boilereffi ciency and to avoid overheating of theheat ing surfaces the values given in the tableshould not be exceeded (dependent onboiler performance ratings - for multi-boilerplants rating of smallest boiler applies - andon the water content of the plant).-- The total amount of filling and replacementwater which is used throughout the total servicelife of the boiler must not exceed threetimes the water capacity of the plant.Heating System- The boilers may not be set up in areas withhalogen compounds occur and may enterthe combustible air (e.g. washing, drying,workshop areas, hairdressing salons etc).- Halogen compounds can be caused byTotal hardness of filling water up to ..[mol/m 3 ] 1 3,0f°H 30d°H 16,8e°H 21,3~mg/l 300Conductance 2 600Boiler size ofindividual boiler50 to 200 kWNOREQUIREMENTmaximum filling quantity without demineralization50 l/kW 20 l/kW 20 l/kW always desalinateclean ing, degreasing and solvent agents,ad hesives and bleaching liquids. Take noteof the Procal instruction leaflet, CorrosionThrough Halogen Compounds.- The heating area must comply with fire serviceregulations.- The heating area doors must be closed becausethe thermal buoyancy in the buildingcan lead to a drop in pressure which worksagainst the flue pressure.- The supply of combustion air must be guaranteed.The air supply opening must beplac ed in the zone of the main wind directionand there must be no possibility of closingit. Minimum air requirement 4.2 m 3 /h perkW boiler maximum capacity. Minimum freecross section for the air opening 13 cm 2 /kW.Space requirementssee separate dimensioned drawing.Energy storage deviceThe installation of an energy storage is generallyrecommended. For oversized boilers(≥ 20 %) or if parts of the heat diffusion systemare often disconnected, a storage tank isimperative.For hot water generation a storage tank is necessaryin most cases. Standard size: 10 - 30litre/kW boiler output.An accurate determination of the plant dimensioningis necessary.Heating InstallationReturn maintenance- A boiler return maintenance must be providedto safeguard a minimum boiler returntem perature of 45 °C. Take note of the hydraulicapplication examples.Hydraulic operation- Take note of the application examplesHeat distribution- For room heating an automatic temperaturecontrol with one or several mixer circuitsmust be supplied.Plant with open expansion tank- The height of the apparatus must ensurethat the required minimum pressure inthe in take connection of the pump for theavoid ance of cavitation is reached (see catalogue“Biral Pumps”)Plant with pressure expansion tankHoval BioLyt (50-70)- with inbuilt thermal flow feed safety device.- Inspected according to EN 303-5.- The expansion and safety engineeringequip ment necessary for the heating plantare to measured and applied outside theboiler according to engineering rules.1sum of alkaline earths2If the conductance in µS/cm exceeds the tabular value an analysis of the water is necessary.458Subject to modification, 1.6.2010

Hoval BioLyt (50-70)EngineeringSafety valveA safety valve and an automatic air bleedermust be installed on the flow.Thermal flow safeguardThe heat exchanger must be connected to thecold water supply at a minimum required flowpressure of 2 bar and minimum capacityBioLyt (50) 2000 l/hBioLyt (70) 2000 l/hFlue-/exhaust gas plantDamper and explosion door- The installation of an explosion door is compulsory.An explosion door must be installedin the connecting line or in the flue inside theheating area.Connecting pipe- The exhaust connecting pipe between theheating boiler and the flue must be connectedinto the flue at an angle of between 30and 45°.- If the length is greater than 1m insulation isrequired.- The fitting of the connecting pipe to the fluemust be carried out in such a way that nocon densation water can flow into the heatingboil er. Do not directly wall in exhaust pipebut connect it flexibly so that transmission ofnoise can be avoided.Flue plant- BioLyt downward pressure: min. 0.05 mbar- The exhaust plant must be unaffected bymois ture, acid resistant, emission burn resistantand suitable for exhaust temperaturesof 70-160 °C.- With existing flue installations, the cleaningmust take place according to informationfrom the chimney builder.- Pay attention to SIA recommendation Number384/4 „Chimneys for building heating,cross section identification”.Non binding standard values for flue diameterThe following are standard values:A precise calculation of the output capacitymust take place.Fundamentals: Smooth wall flues made ofchrome steel pipe connecting pipe ≤ 2.5 m with0.5 m taper, 1 curve 90° and 1 angle 45°, Σζ= 0,8. Connecting pipe of same Ø as exhaustconnections of heating boiler, connecting pipeand flue with insulation 40 mm.

The nozzle mustbe directed outwards via the insulation.DSubject to modification, 1.6.2010459
