. Important information. Flue A properly dimensioned flue is required for optimum functioning of the combustion system. Calculation of the dimensions must follow EN 3384-. See the technical data section for the values required for this calculation. Please note that in the lower performance range. flue gas temperature may be below 60 C. The flue gas system must display at least the following classification: Temperature class: T400 = nominal operating temperature 400 C Soot fire resistance class: G = flue gas system with soot fire resistance Corrosion resistance class: = suitable for unprocessed wood fuels We would recommend fitting an energy-saving intake regulator for problem-free operation. This will largely prevent moisture in the flue. and losses resulting from down-time will be reduced (draught interruptions). If you have a feed pressure (flue draught) of more than 0.0 mbar. the energy-saving intake regulator must be fitted. Note! We would recommend fitting the draught limiter outside the flue. around ½ m below where the exhaust pipe enters the flue. CAUTION Frequently. overhauling existing systems involves over-sized flue cross-sections or flues not designed for low-temperature operation. We recommend an evaluation by the local building inspector before installing the boiler system. In this way appropriate modifications can be made to the flue before system installation (see technical data for flue calculation values)..3 Boiler room/installation room DANGER The configuration of the entire system must comply with the requirements of regional legislation. applicable regulations. standards and guidelines. The minimum clearances for connections. cleaning and maintenance must be complied with see Section.3.3 Minimum service clearances. Sufficient ventilation of the set-up area must be assured. See Section..0 Combustion air. The boiler may only be installed in a dry location! The boiler may not be installed in rooms that are very dusty or humid. Permissible limit values: Humidity: max. 85 % at room temperature of 5 C (non-condensing) Room temperature: + to +40 C Sufficient lighting must be provided for service and maintenance. 5

. Important information.4 Initial start-up and operating instructions DANGER Unauthorised start-up! Windhager Customer Service or the customer service partner must start up the boiler/ system first of all. and will familiarise the customer with the system operation and cleaning of the boiler. with reference to the operating manual. The following preconditions must be met before you order the initial start-up:.) Boiler installed correctly..) System fully wired up electrically. 3.) System rinsed. filled and vented heat consumption must be possible. 4.) Hot water tank connected to domestic water and filled. 5.) Sufficient quantity of fuel available. 6.) The customer must be present during start-up. The initial start-up cannot be carried out if any of these points are neglected. The customer will be charged for any unnecessary costs arising as a result. Start-up and maintenance by Windhager Customer Service or a customer service partner are part of the guarantee requirements of the enclosed "Warranty conditions". Note! When the boiler is started for the first time. bad smells may result from gas emissions from insulation or paint residue being burnt off. Ensure that the boiler room/installation room is therefore well vented. Condensation may also form near the coasting surfaces and the combustion chamber temperature may only increase after a delay..5 Disposal/recycling Disposing of the packaging The packaging material (wooden crate. cardboard boxes. inserts. plastic films and plastic bags. etc.) must be disposed of correctly in line with the local legal provisions and regulations. Disposing of components or the boiler To dispose of defective components or the heating system (e.g. boiler or control system) after the product life has expired. please observe the following information: Dispose of the items correctly. i.e. separate the parts to be disposed of into material groups. Do not simply dispose of electrical or electronic waste with the general waste under any circumstances; instead. use the public collection points provided for this purpose. As a matter of principle. dispose of items in a way that is as sustainable as possible and that is in line with the current environmental protection. reprocessing and disposal technology. 6

. For the installer. For the installer. Scope of supply. packaging Boiler covered with a plastic sack. The cladding. control panel and small parts can be found in separate cardboard boxes and in the filler chamber. Fig. 3 Cardboard boxes with cladding and control panel Fig. LogWIN Premium Touch boiler. System.. Area of use For heating buildings acc. to EN 83. The boilers are designed and approved as heat generators for hot water heating systems with permissible flow temperatures of up to 90 C. They may be installed only in sealed systems. The max. boiler temperature for the LogWIN is limited in the factory to 80 C. The resulting flow temperature depends on the relevant operating status and the line losses to the system... Standards The following European Standard should be followed: EN 88. according to this the following should be fitted: a) A closed expansion tank. b) A reliably functioning safety valve (with max. 3 bar reaction pressure) installed at the highest point of the boiler or at a non-closable line. c) A thermometer. a pressure gauge. d) An automatic device for dissipating heat which will prevent the maximum water temperature in the boiler of 0 C from being exceeded. The built-in thermal safety device (heat exchanger) should always be used with the thermal discharge safeguard. e) A low-water cut-off: A low-water cut-off is not required for systems providing up to 300 kw nominal thermal output. if it can be ensured that a lack of water in the system will not result in excess heating. If the boiler is above the radiators. then a low-water cut-off must be installed. 7

. For the installer..3 Heat accumulator (buffer) The installation of a heat accumulator (buffer tank) is required by the following standards and laws: EN 303-5. BImSchV Art. 5a of the Small Combustion Devices Agreement (Austria) Air Protection Ordinance (Switzerland) Having a correctly sized heat accumulator (buffer tank) is essential for correct operation of a wood-fired heating system. The fuel must always be selected and the heat load of the building calculated. The type of heating (e.g. bringing the hot water tank up to temperature in summer) and system design (underfloor and/or radiator heating circuits) should also be taken into account. CAUTION Rooms that are not heated at times (guest rooms. living areas only used at weekends. etc.) must be subtracted from the calculated heat load (QH) for the tank configuration! Recommended heat accumulator volume (buffer tank volume) Wood gasification boiler Boiler model Recommend heat accumulator volume LWP 80T 305T 000 litres LogWIN LWP 360T / 365T 500 litres LWP 500T / 505T 3000 litres Note! To calculate the minimum heat accumulator volume (buffer tank volume). see the planning documents...4 Heating circuits Several heating circuits: In-line regulating valves must be installed to permit better regulation of the system. In a building without insulation (new building. not yet plastered) the calculated and actually required heating requirements often differ to a considerable extent. Minimum heat consumption: The smallest possible boiler power must be continuously dissipated from the boiler during operation. Suitable measures to ensure minimum heat consumption should be maintained throughout the entire burning time. e.g.: Correctly dimensioned buffer tank. see Section..3 Using the MES INFINITY control function in the buffer load functional module. incl. no thermostatic valves Non-blockable heating circuit. e.g. never fully close manual mixing valve. incl. no thermostatic valves Note! Mixer valve: If operating with a manual mixing valve or the control system. elevated room temperatures may sporadically occur. A 3-way mixer valve is always necessary; in conjunction with outside temperature control. there must be a 3-way motorised mixing valve and a buffer tank. Underfloor heating: Only possible with a buffer tank (with outside temperature control. motorised mixing valve). Return flow temperature increase: This is necessary in all systems with a heat accumulator and a buffer tank and in old systems with a large volume of water (> 00 l). With the LogWIN. it is essential for the temperature of the return flow to be kept to at least 45 C during 8

. For the installer heating. otherwise the temperature of the return flow must be increased using a mixing pump or valve. In order to achieve good temperature stratification in the heat accumulator or buffer tank. we recommend setting the boiler circuit to a 5 0 K differential by means of the return hold-up group SK RH. See the enclosed instructions for the return hold-up group for guidance values for the setting. Boiler start-up relief: A boiler start-up relief must be installed and connected in all cases so that the circulation pump(s) turn off when the boiler temperature is below 60 C. This prevents condensation forming in the boiler and extends its service life. This type of boiler start-up relief is included in the MES INFINITY control system buffer load function module and the MES PLUS WVF+ module...5 Circulation pump Since 03. regulations in Europe require that new circulation pumps satisfy a minimum level of energy efficiency. The Energy Efficiency Index (EEI) must be observed...6 Heating water CAUTION The chemical composition of the heating water must comply with the requirements of regional legislation. regulations. guidelines and standards. e.g. ÖNORM H 595. VDI 035. SWKI BT 0-0. Applicable for Austria (excerpt from ÖNORM H 595): a) According to ÖNORM H 595 (issue 00). the condition of the heating water must be checked every years by a heating technician in order to avoid corrosion and sediment accumulation in the heating system. b) The pipe lines and heating appliances should be thoroughly flushed through before the boiler is connected. c) To protect the boiler from contamination from the heating system. installation of a dirt trap is required in old or existing systems with maintenance cocks installed in the return line. d) If oxygen diffusion or sludge build-up cannot be prevented. the system must be segregated by means of a heat exchanger. e) If antifreeze is used. a minimum volume of 5 % antifreeze is required. otherwise corrosion prevention is not guaranteed...7 Domestic water (bringing the hot water tank up to temperature in summer) There may still be fuel in the boiler after the hot water tank has been brought up to temperature. As a result. measures must be taken to dissipate the surplus energy see Section..4 Heating circuits; Minimum heat consumption...8 Combination with automatic boiler (e.g. pellet or oil-fired boiler) If the LogWIN and an automatic boiler (e.g. pellet or oil-fired boiler) are connected to one flue without an MES INFIN- ITY buffer load function module or MES PLUS WVF+ module. in the case of LogWIN a flue gas thermostat (accessory OK-050) must be installed to prevent parallel operation on the same flue. 9

. For the installer..9 Water-side resistance (pressure loss) LWP 80T 505T Flow rate (m 3 /h) Diagram LogWIN water-side resistance Pressure loss (mbar)..0 Combustion air The combustion air is drawn directly by the boiler from the installation room. therefore the installation room has to be adequately ventilated. The combustion air should be directed to the vicinity of the boiler and must be free from pollutants (gases. vapours and dusts). otherwise malfunctions and increased wear (e.g. corrosion) may occur. DANGER The configuration of the entire system must comply with the requirements of regional legislation. applicable regulations. standards and guidelines. Applicable for Austria (excerpt from ÖNORM H 570): The area of the free minimum cross-section must be 5 cm per kw of the boiler's nominal total output. The opening to the outdoors for combustion air should be designed as follows: The flow of air must not be restricted in any way by the weather (e.g. snow. leaves). The free cross-section area remains the same when taking the cover grille. discs. etc.. into consideration. Applicable for Germany (excerpt from the Firing Ordinance. September 007): For hearths with a nominal output of not more than 50 kw in total that are dependent on surrounding air. supply of combustion air will be sufficient providing that every installation rooms has an opening that vents to the atmosphere with an unobstructed cross-section of at least 50 cm or two openings of 75 cm each. or pipes leading outside with a technically equivalent cross-section. CAUTION Malfunctions or complaints occasioned by inadequate combustion air will not be covered by the guarantee. The boiler's nominal total output is the sum of the nominal outputs of all heat generators installed in the same boiler / installation room. 0

Taking into the building and installing The appliance must be taken into the building and installed without subjecting it to significant knocks and jolts. in order to avoid damaging the combustion chamber and the shifting of parts. All warranty claims will be invalidated if the appliance is damaged due to having been taken into the building and installed incorrectly or if the appliance malfunctions as a consequence of this. The boiler may only be transported vertically and without its cladding. The easiest way to do this is with a lift truck or by rolling on pipes. If transporting via stairs. etc.. the boiler should be secured appropriately. For installation dimensions. refer to the technical data in Section 4.5 and Section 4.7. Note! There is a crane lug on the top of the LogWIN for transporting using winches.

. For the installer.3.9 Installing the exhaust pipe a) Install the exhaust pipe upward to the flue (45 is the ideal angle). Maximum exhaust pipe length 3 m. CAUTION Any section of this exhaust line that only rises slightly (up to 30 ) or is horizontal is not allowed to be more than m in length. b) Avoid 90 bends. 45 bends are better. c) Do not push the exhaust pipe too far into the flue. d) Do not seal the exhaust pipe completely into the flue. Connection with flexible exhaust pipe inlet into the flue. The included draught blower can cause sound transmissions that create noise pollution. e) The LogWIN is a low-pressure boiler. This means that the flue gas system needs to meet the "N" seal integrity requirement according to EN 856- and EN 856-. Please ensure a sufficient immersion depth when fitting (e.g. when using Windhager stainless steel flue systems). f) The entire exhaust line should be insulated to a minimum of cm thickness in order to prevent or minimise condensation. g) A draught limiter is needed if the maximum draught (see technical data. Section 4.4 or 4.6) is exceeded during operation. Note! We would recommend fitting the draught limiter outside the flue. around ½ m below where the exhaust pipe enters the flue. DANGER The configuration of the exhaust line must comply with technical fire protection requirements in accordance with the applicable legislation. regulations. guidelines and standards refer also to Section.3.3. Minimum clearances for fire protection. cleaning and maintenance..3.30 Installing the thermal discharge safeguard Connecting thermal discharge safeguard to thermal safety device a) The thermal discharge safeguard and cleaning T-piece must still be accessible after installation. b) Water must be seen to be draining out in order to check the function. therefore use a discharge funnel. c) It must not be possible to block the connection manually.

3. For the electrician 3. For the electrician 3. Electrical connections The boiler and related accessories are designed to be installed only in dry areas (protection type IP 0). Installation of electrical components may only be performed by a qualified technician. The regulations and specifications of ÖVE. VDI. SEV and local ordinances must be followed. DANGER The phases of the 30 V electrical power supply must be connected correctly (Fig. 97). otherwise the blower might still be live even after the mains fuse has blown. The mains connection must be protected against short circuit with a 3 A delayed-action fuse. We recommend using fine-wire PVC sheathed cables. e.g. H05VV-F (YMM-J) with a 3x.5 mm nominal cross-section. Each boiler is pre-wired and internally fused with a T 6.3 A fine-wire fuse to protect against short circuit. In areas with increased power surge risk (e.g. lightning strikes in regions prone to storms). we recommend installation of an appropriate surge protector. F fuse T 3.6 A Safety temperature limiter Service plug Control panel Fig. 8 LogWIN control panel rear view CAUTION Electrical cables must not touch heating and exhaust pipes nor must they come in contact with non-insulated boiler components. They are to be sufficiently braced and provided with a protective tube. The electrical connections are located in or behind the control panel and the power plug at the rear of the boiler cladding Fig. 97. The motherboards are located inside the control panel and the connection terminals on the outside on control panel cover (screwless cage-spring-type terminals). MES Infinity control system (if available): The MES INFINITY control system (heating circuit and buffer load/switching function modules) is supplied and must be connected electrically. Maximum switching capacity of the MES INFINITY control system: Relay outputs: 30 V AC. 6 A ( A inductive). 50 Hz Buffer load function module with X/X contact: Solid-state relay: 30 V AC.
