APIANCE SCIPTION MOLS - PTIGE 4-3 SOLO / EXCELLCE The Prestige is a wall-hung condsing boiler meeting the requiremts of currt H-Top standards in elgium. The boiler is certified compliant with EC standards as a connected appliance: C3(x) - C33(x) - C43(x) - C53(x) - C63(x) - C83(x) - C93(x), but it can also be connected as an op appliance in category 3 or as an appliance of category 3P, which can operate with a positive pressure. The Solo series is a system boiler, that can be operated in combination with the whole range of ACV Domestic Hot ater (DH) tanks, using a specific kit, while the Excellce series has a built-in DH tank (54L) and can work as a standalone appliance providing both heating and domestic hot water. The boiler features a built-in frost protection mechanism: as soon as the flow temperature [NTC probe] drops below 7 C, the ctral heating pumps are activated. As soon as the flow temperature is at 5 C, the burner starts up until the flow temperature rises above 5 C. The pumps continue to run for around 0 minutes. The function can be abled or disabled through the installer mu. h the frost protection is disabled, only the pumps operate. An anti-freeze function is also available if an outdoor temperature ssor is connected, the pumps are activated wh the outside temperature drops below the threshold defined through the Freeze protection function in the installer mu.

TECHNICAL CHAACTEISTICS ECOMMDATIONS FO THE PEVTION OF COOSION AND SCALING IN HEATING SSTEMS How oxyg and carbonates can affect the heating system Oxyg and dissolved gasses in the water of the primary circuit contribute to the oxidation and the corrosion of the system componts that are made of ordinary steel (radiators,...). The resulting sludge is th deposited in the appliance exchanger. The combination of carbonates and carbon dioxide in the water results in the formation of scale on the hot surfaces of the installation, including those of the appliance exchanger. These deposits in the heat exchanger reduce the water flow rate and thermally insulate the exchange surfaces, which is likely to damage them. Sources of oxyg and carbonates in the heating circuit The primary circuit is a closed circuit; the water it contains is therefore isolated from the mains water. h maintaining the system or filling up the circuit, water rewal results in the addition of oxyg and carbonates in the primary circuit. The larger the water volume in the system, the larger the addition. Hydraulic componts without an oxyg barrier (PE pipes and connections) admit oxyg into the system. Prevtion Principles. Clean the existing system before installing a new appliance - efore the system is filled, it must be cleaned in accordance with standard 4336. Chemical cleaning agts can be used. - If the circuit is in bad condition, or the cleaning operation was not efficit, or the volume of water in the installation is substantial (e.g. cascade system), it is recommded to separate the appliance from the heating circuit using a plate-to-plate exchanger or equivalt. In that case, it is recommded to install a hydrocyclone or magnetic filter on the installation side.. Limit the fill frequcy - Limit fill operations. In order to check the quantity of water that has be added into the system, a water meter can be installed on the filling line of the primary circuit. - Automatic filling systems are not recommded unless the fill frequcy is monitored and the scale and corrosion inhibitor remain at the correct levels. - If your installation requires frequt water refilling, make sure your system is free of water leaks. - Inhibitors may be used in accordance with standard 4868. 3. Limit the presce of oxyg and sludge in the water - A deaerator (on the appliance flow line) combined with a dirt separator (upstream of the appliance) must be installed according to the manufacturer's instructions. - ACV recommds using additives that keep the oxyg in solution in the water, such as Fernox (www.fernox.com) and Stinel (www.stinel-solutions.net) products. - The additives must be used in accordance with the instructions issued by the manufacturer of the water treatmt product. 4. Limit the carbonate conctration in the water - The fill water must be softed if its hardness is higher than 0 fh (, dh). - Check regularly the water hardness and ter the values in the service log. - ater hardness table : ater hardness fh dh mmolca(hco3) / l Very soft 0-7 0-3.9 0-0.7 Soft 7-5 3.9-8.4 0.7 -.5 Fairly hard 5-5 8.4-4.5 -.5 Hard 5-4 4-3.5.5-4. Very hard > 4 > 3.5 > 4. 5. Control the water parameters - In addition to the oxyg and the water hardness, other parameters of the water must be checked. - Treat the water if the measured values are outside the range.

TECHNICAL CHAACTEISTICS G3 EQUIEMTS AND GUIDANCE - UK O Discharge pipe from safety valves The uilding egulation G3 requires that any discharge from an unvted system is conveyed to where it is visible, but will not cause danger to persons in or about the building. The tundish and discharge pipes should be fitted in accordance with the requiremts and guidance notes of uilding egulation G3. The G3 equiremts and Guidance sections 3.50-3.63 are detailed below. For discharge pipe arrangemts not covered by G3 Guidance advice should be sought from your local uilding Control Officer. Main characteristics : Any discharge pipe connected to the pressure relief devices (Expansion Valve and Temperature/ Pressure elief Valve) must be installed in a continuously downward direction and in a frost free vironmt. ater may drip from the discharge pipe of the pressure relief device. This pipe must be left op to the atmosphere. The pressure relief device is to be operated regularly to remove lime deposits and to verify that it is not blocked. A typical discharge pipe arrangemt is shown on next page. Geral remarks Discharge pipe-work D can now be a plastic pipe but only pipes that have be tested to a minimum 0 C must be used. Discharge pipe D can now be plumbed into the soil stack but only soil stacks that can handle temperatures of 99 C or greater should be used. Extract from The uilding egulation G3 : Discharge pipe D 3.50 Safety devices such as temperature relief valves or combined temperature and pressure and pressure relief valves (see paragraphs 3.3 or 3.8) should discharge either directly or by way of a manifold via a short lgth of metal pipe (D) to a tundish. 3.5 The diameter of discharge pipe (D) should be not less than the nominal outlet size of the temperature relief valve. 3.5 here a manifold is used it should be sized to accept and discharge the total discharge from the discharge pipes connected to it. 3.53 here valves other than the temperature and pressure relief valve from a single unvted hot water system discharge by way of the same manifold that is used by the safety devices, the manifold should be factory fitted as part of the hot water storage system unit or package. Tundish 3.54 The tundish should be vertical, located in the same space as the unvted hot water storage system and be fitted as close as possible to, and lower than, the valve, with no more than 600mm of pipe betwe the valve outlet and the tundish. Note: To comply with the ater Supply (ater Fittings) egulations, the tundish should incorporate a suitable air gap. UK 3.55 Any discharge should be visible at the tundish. In addition, where discharges from UK safety devices may not be appart, e.g. in dwellings occupied by people with impaired vision or mobility, consideration should be giv to the installation of a suitable safety device to warn wh discharge takes place, e.g. electronically operated. Discharge pipe D 3.56 The discharge pipe (D) from the tundish should: (a) have a vertical section of pipe at least 300mm long below the tundish before any elbows or bds in the pipework; and (b) be installed with a continuous fall thereafter of at least in 00. 3.57 The discharge pipe (D) should be made of: (a) metal; or (b) other material that has be demonstrated to be capable of safely withstanding temperatures of the water discharged and is clearly and permantly marked to idtify the product and performance standard (e.g. as specified in the relevant part of S 79) 3.58 The discharge pipe (D) should be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalt hydraulic resistance exceeds that of a straight pipe 9m long, i.e. for discharge pipes betwe 9m and 8m the equivalt resistance lgth should be at least two sizes larger than the nominal outlet size of the safety device; betwe 8 and 7m at least 3 sizes larger, and so on; bds must be tak into account in calculating the flow resistance. See figure, table and the worked example. 3.59 here a single common discharge pipe serves more than one system, it should be at least one pipe size larger than the largest individual discharge pipe (D) to be connected. 3.60 The discharge pipe should not be connected to a soil discharge stack unless it can be demonstrated that that the soil discharge stack is capable of safely withstanding temperatures of the water discharged, in which case, it should: (a) contain a mechanical seal, not incorporating a water trap, which allows water into the branch pipe without allowing foul air from the drain to be vtilated through the tundish; (b) be a separate branch pipe with no sanitary appliances connected to it; (c) if plastic pipes are used as branch pipes carrying discharge from a safety device they should be either polybutale (P) to Class S of S 79-:006 or cross linked polyethyle (PE-X) to Class S of S 79-3:006; and (d) be continuously marked with a warning that no sanitary appliances should be connected to the pipe. Note:. Plastic pipes should be joined and assembled with fittings appropriate to the circumstances in which they are used as set out in S ISO 043-.. here pipes cannot be connected to the stack it may be possible to route a dedicated pipe alongside or in close proximity to the discharge stack. Termination of discharge pipe 3.6 The discharge pipe (D) from the tundish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge. 3.6 Examples of acceptable discharge arrangemts are: (b) to a trapped gully with the d of the pipe below a fixed grating and above the water seal; (c) downward discharges at low level; i.e. up to 00mm above external surfaces such as car parks, hard standings, grassed areas etc. are acceptable providing that a wire cage or similar guard is positioned to prevt contact, whilst maintaining visibility; and (d) discharges at high level: e.g. into a metal hopper and metal downpipe with the d of the discharge pipe clearly visible or onto a roof capable of withstanding high temperature discharges of water and 3m from any plastic guttering system that would collect such discharges. 4 Prestige 4-3 Solo/Excellce : A004335-6646700 D
TECHNICAL CHAACTEISTICS 3.63 The discharge would consist of high temperature water and steam. Asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges. UK orked example of discharge pipe sizing Figure on the left shows a G/ temperature relief valve with a discharge pipe (D) having 4 No. elbows and lgth of 7m from the tundish to the point of discharge. From Table: UK temperature relief valve to tundish Maximum resistance allowed for a straight lgth of mm copper discharge pipe (D) from a G/ temperature relief valve is 9.0m. 600mm maximum Tundish Subtract the resistance for 4 No. mm elbows at 0.8m each = 3.m Therefore the permitted lgth equates to: 5.8m 5.8m is less than the actual lgth of 7m therefore calculates the next largest size. 300mm minimum Maximum resistance allowed for a straight lgth of 8mm pipe (D) from a G/ temperature relief valves equates to 8m. Subtract the resistance of 4 No. 8mm elbows at.0m each = 4.0m Therefore the maximum permitted lgth equates to: 4m Metal discharge pipe (D) tundish with continuous fall. See 3.56, Table G3 and worked example Figure G3: Typical discharge pipe arrangemt Discharge below fixed grating (3.6 gives alternative points of discharge) Fixed grating Trapped gulley As the actual lgth is 7m, a 8mm (D) copper pipe will be satisfactory. Esstial recommdations for safety The temperature/pressure relief valve should only be replaced by a compett person. No control or safety valves should be tampered with or used for any other purpose. The discharge pipe should not be blocked or used for any other purpose.

INSTALLATION SAFET INSTCTIONS FO THE INSTALLATION Geral remarks The connections (electrical, flue pipe, hydraulic) must be carried out in accordance with local standards and regulations in force. If the water drawing off point is far from the tank, installing an auxiliary DH loop can allow to get hot water more quickly at all times. Esstial recommdations for the correct operation of the appliance The boiler must be installed in a dry and protected area, with an ambit temperature comprised betwe 0 and 45 C. Install the appliance to sure easy access at all times. To avoid any risk of corrosion, connect the stainless steel DH production tank directly to the earth. Make sure that the mains water used to fill the boiler has a minimum pressure of. bar. Make sure to install a pressure reducing valve set at 4.5 bar if the mains supply pressure is in excess of 6 bar. The DH circuit must be fitted with an approved safety group, comprised of a 7 bar safety valve, a check valve and a shut-off valve. If works need to be performed (in the boiler room or close to the air vts), make sure to turn off the boiler to prevt dust from tering and accumulating in the boiler heating system. Esstial recommdations for safety Install the boiler on a base made of non-combustible materials. Do not store any corrosive products, paint, solvts, salts, chloride products and other detergt products near the appliance. Make sure that all air vts are unobstructed at all times. A condsation outlet connected to the sewer must be fitted close to the boiler to prevt the condsation products from the flue pipe from running into the boiler. Install a condsate neutralisation system if required by national and/or local regulations and have it cleaned regularly. The horizontal flue pipes must be installed with a slight slope of 5 cm per meter, so that the acid condsation water flows to a condsate recovery container and does not damage the heating body. Only use ACV flue systems to connect this appliance to sure that the pipe and connection diameters all match. Hot water can cause scalding! In the evt of small amounts of hot water repeatedly being drawn off, a stratification effect can develop in the tank. The upper hot water layer may th reach very high temperatures. The temperature of the domestic hot water can be adjusted up to 75 C in the boiler. However, the temperature of the domestic hot water at the drawing off point must comply with local regulations. ACV recommds using a pre-set thermostatic mixing valve in order to provide hot water at a maximum of 60 C. The risk of developing bacteria exists, including Legionella pneumophila, if a minimum temperature of 60 C is not maintained in both the DH tank and the hot water distribution network. ater heated to wash clothes, dishes and for other uses can cause serious burns. In order to avoid exposure to extremely hot water that can cause serious burns, never leave childr, old people, disabled or handicapped people in the bath or shower alone. Never allow young childr to turn on the hot water or fill their own bath. Esstial recommdations for the electrical safety Only an approved installer is authorized to carry out the electrical connections. Install a -way switch and a fuse or circuit breaker of the recommded rating outside the appliance, so as to be able to shut power down wh servicing the appliance or before performing any operation on it. Isolate the external electrical supply of the appliance before performing any operation on the electrical circuit. This appliance is not intded for use by persons (including childr) with reduced physical, ssory or mtal capabilities, or lack of experice and knowledge, unless supervised or unless they have be giv instruction concerning the use of the appliance by a person responsible for their safety. * For UK specific requiremts for the discharge from safety valves, refer to «G3 equiremts and Guidance - UK Only» on page 4. 6 Prestige 4-3 Solo/Excellce : A004335-6646700 D
