JG 2010 Part I No. 4. EN ISO 17225-2 EN ISO 17225-4 Solid bio-fuel - Fuel specifications and classes Part 2: Wood pellets for use in industrial and domestic systems Solid bio-fuel - Fuel specifications and classes Part 4: Wood chips for non-industrial use 2.4.2 Installation and approval of the heating system Note on standards The boiler should be operated in a closed heating system. The following standards govern the installation: EN 12828 - Heating Systems in Buildings NOTICE! Each heating system must be officially approved. The appropriate supervisory authority (inspection agency) must always be informed when installing or modifying a heating system, and authorisation must be obtained from the building authorities: Austria: report to the construction authorities of the community or magistrate Germany: report new installations to an approved chimney sweep / the building authorities. 2.4.3 General information for installation room (boiler room) Boiler room characteristics The floor must be even, clean and dry and have an adequate load-bearing capacity. There must not be a potentially explosive atmosphere in the boiler room as the boiler is not suitable for use in potentially explosive environments. The boiler room must be frost-free. The boiler does not provide any light, so the customer must ensure sufficient lighting in the boiler room in accordance with national workplace design regulations. When using the boiler above 2000 metres above sea level you should consult the manufacturer. Danger of fire due to flammable materials. The floor of the boiler room must not be flammable. No flammable materials should be stored near the boiler. Flammable objects (e.g. clothing) must not be put on the boiler to dry. 8 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com

Safety Design Information 2 Damage due to impurities in combustion air. Do not use any solvents or cleaning agents containing chlorine and hydrogen halides in the room where the boiler is installed (e.g. chlorination units for swimming pools). Keep the air suction opening of the boiler free of dust. The system must be protected against the chewing or nesting of animals (e.g. rodents etc.). Ventilation of the boiler room Ventilation air for the boiler room should be taken from and expelled directly outside, and the openings and air ducts should be designed to prevent weather conditions (foliage, snowdrifts, etc.) from obstructing the air flow. Unless otherwise specified in the applicable building regulations for the boiler room, the following standards apply to the design and dimensions of the air ducts: Note on standards ÖNORM H 5170 - Construction and fire protection requirements TRVB H118 - Technical directives on fire protection/prevention 2.4.4 Requirements for central heating water Unless contrary to other national regulations, the latest versions of the following standards and guidelines apply: Austria: Germany: ÖNORM H 5195 VDI 2035 Switzerland: Italy: SWKI BT 102-01 UNI 8065 Observe the standards and also follow the recommendations below: Aim for a ph value of between 8.2 and 10.0. If the central heating water comes into contact with aluminium, the ph value must be between 8.0 and 8.5 Use prepared water which complies with the standards cited above for filling and makeup water Avoid leaks and use a closed heating system to maintain water quality during operation When filling with make-up water, always bleed the filling hose before connecting, in order to prevent air from entering the system Advantages of prepared water: Complies with the applicable standards Less of a drop in output due to reduced limescale build-up Less corrosion due to fewer aggressive substances Long-term cost savings thanks to improved energy efficiency Installation Instructions T4 24-150 M1211017_en 9

2 Safety Design Information Limit values for filling and make-up water: Austria Germany Switzerland Total hardness 1.0 mmol/l 2.0 mmol/l < 0.1 mmol/l Conductivity - < 100µS/cm < 100 µs/cm ph value 6.0 8.5 6.5 8.5 6.0 8.5 Chloride < 30 mg/l < 30 mg/l < 30 mg/l Additional requirements for Switzerland: The filling and make-up water must be demineralised (fully purified) The water must not contain any ingredients that could settle and accumulate in the system This makes the water non-electroconductive, which prevents corrosion It also removes all the neutral salts such as chloride, sulphate and nitrate which can weaken corrosive materials in certain conditions If some of the system water is lost, e.g. during repairs, the make-up water must also be demineralised. It is not enough to soften the water. The heating system must be professionally cleaned and rinsed before filling the units. Inspection: After eight weeks, the ph value of the water must be between 8.2 and 10.0. If the central heating water comes into contact with aluminium, the ph value must be between 8.0 and 8.5 Yearly. Values must be recorded by the owner 2.4.5 Notes for using pressure maintenance systems Pressure maintenance systems in hot-water heating systems keep the required pressure within predefined limits and balance out volume variations caused by changes in the hot-water temperature. Two main systems are used: Compressor-controlled pressure maintenance In compressor-controlled pressure maintenance units, a variable air cushion in the expansion tank is responsible for volume compensation and pressure maintenance. If the pressure is too low, the compressor pumps air into the tank. If the pressure is too high, air is released by means of a solenoid valve. The systems are built solely with closed-diaphragm expansion tanks to prevent the damaging introduction of oxygen into the heating water. Pump-controlled pressure maintenance A pump-controlled pressure maintenance unit essentially consists of a pressuremaintenance pump, relief valve and an unpressurised receiving tank. The valve releases hot water into the receiving tank if the pressure is too high. If the pressure drops below a preset value, the pump draws water from the receiving tank and feeds it back into the heating system. Pump-controlled pressure maintenance systems with 10 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com

Safety Design Information 2 open expansion tanks (e.g. without a diaphragm) introduce ambient oxygen via the surface of the water, exposing the connected system components to the risk of corrosion. These systems offer no oxygen removal for the purposes of corrosion control as required by VDI 2035 and in the interests of corrosion protection should not be used. 2.4.6 Return temperature control If the hot water return is below the minimum return temperature, some of the hot water outfeed will be mixed in. CAUTION Risk of dropping below dew point/condensation formation if operated without return temperature control. Condensation water forms an aggressive condensate when combined with combustion residue, leading to damage to the boiler. Take the following precautions: We recommend using a return temperature control. The minimum return temperature is 45 C. We recommend fitting some sort of control device (e.g. thermometer). 2.4.7 Use with storage tank NOTICE In principle it is not necessary to use a storage tank for the system to run smoothly. However, we recommend that you use the system with a storage tank, as this ensures a continuous supply of fuel in the ideal output range of the boiler. For the correct dimensions of the storage tank and the line insulation (in accordance with ÖNORM M 7510 or guideline UZ37) please consult your installer or Froling.

2 Safety Design Information 2.4.8 Chimney connection/chimney system EN 303-5 specifies that the entire flue gas system must be designed to prevent, wherever possible, damage caused by seepage, insufficient feed pressure and condensation. Please note in this respect that flue gas temperatures lower than 160K above room temperature can occur in the permitted operating range of the boiler. The flue gas temperatures (for clean systems) and additional flue gas values can be found in the table below. The connection between the boiler and the chimney system should be as short as possible. The upward angle of the connection should not exceed 30-45. Insulate the connection. The entire flue gas system - chimney and connection - should be calculated in accordance with EN 13384-1. Local regulations and other statutory regulations also apply. NOTICE! The chimney must be authorised by a smoke trap sweeper or chimney sweep. NOTICE! TRVB H 118 (Austria only) stipulates that an explosion flap must be installed in the connecting piece (flue pipe) directly next to the boiler. It should be situated in such a way that is poses no risk to persons! Draught limiter We generally recommend the installation of a draught limiter. A draught limiter must be installed if the maximum permissible feed pressure as given in the boiler data for planning the flue gas system is exceeded. NOTICE! Install the draught limiter directly under the mouth of the flue line, as the pressure is constantly low at this point. Measuring port For measuring the emissions of the system, a suitable measuring port must be installed in the connecting piece between the boiler and chimney system. 2 x D D D M In front of the measuring port (M) a straight inlet section should be located at a distance corresponding to about twice the diameter (D) of the connecting piece. A straight outlet section at a distance corresponding to about the single diameter of the connecting piece should be provided after the measuring port. The measuring port must remain closed whenever the system is in operation. Ensure that the outside diameter of the sampling probes in the measuring port can accommodate up to 13 mm. To avoid the ingress of false air, the diameter of the measuring port must not exceed 21 mm. 12 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com
