경동보일러 사용자메뉴얼 번역(영어 원본)Product description These boilers are designed to provide the following services or operating modes: Central Heating (CH): The boiler provides hot water at the desired temperature for a heating installation connected to it. The temperature can be selected using the boiler’s integrated electronic control. Different types of ambient temperature control devices may also optionally be connected to the boiler (room thermostat, ambient temperature sensor, etc.), to enable it to control the temperature inside the home. Lastly, an outdoor temperature sensor (optional) may be connected to the boiler to control the comfort temperature of the installation in accordance with the weather conditions outside the home. Domestic Hot Water (DHW) The boiler provides hot water when a tap in the domestic water installation is turned on. When the boiler is switched on, it automatically provides heating. When a hot tap is turned on, the boiler switches to DHW production mode. DHW production takes priority, and heating production is therefore disabled while it is activated. Models There are three models of NAVIEN boiler, according to the power required: • NAVIEN NCN CE 21K • NAVIEN NCN CE 25K • NAVIEN NCN CE 32K • NAVIEN NCN CE 37K 2. Safety warnings 2.1. Safety symbols All the safety indications in this manual are shown by a warning symbol, which differs depending on the nature of the indication. All the safety messages indicate a potential risk of breakdown or damage and it is therefore very important to carefully follow the instructions given, to prevent any risk of accident or damage to the appliance or to persons. DANGER This symbol warns of operations or situations involving imminent danger and which could cause severe damage to persons or property if they are not avoided. WARNING This symbol is for warnings that must be taken into account for correct use of the appliance and to prevent malfunctioning that could give rise to hazardous situations for the appliance itself and for persons. CAUTION This symbol warns of situations and actions that must be avoided for correct functioning and maintenance of the appliance. This indicates particularly useful information and instructions. 2.2. Safety warnings Read and carefully follow the safety warnings and alerts described below. If you should lose these instructions, contact the boiler installer or manufacturer immediately. DANGER – DO NOT store combustible products such as oil, gas-oil or petrol near the appliance. – DO NOT store easily flammable products (e.g. newspapers or cardboard) near the appliance or fume extraction system (flue). – DO NOT store OR use aerosol sprays containing air, paint or any other substance near the fume extraction system or boiler while it is connected to the gas network. – DO NOT store any materials near the boiler combustion gas outlet or air intake if they could obstruct it. – DO NOT tamper with or light the boiler if its front cover is open. Switching on the boiler in these circumstances could give rise to combustion with a hazardous excess of carbon monoxide (CO), which could cause serious damage to persons or property and even death. DANGER Keep flammable material and fuels away from the boiler. WARNING – Ensure the installer shows you where the gas shut-off valve is located and shows you how to turn it off. Turn off this shut-off valve if you observe any signs of overheating, fire, gas leaks, damage to the appliance or any other sign of boiler malfunctioning. DO NOT turn on the shut-off valve again until it has been inspected by an Authorised Technical Assistance Service technician. – Before switching on the boiler, ensure it is filled with water and that the gas supply is turned on. – Make sure the cold water supply valve is open before switching on the boiler. – DO NOT use the boiler for any purpose other than those described in this manual. – DO NOT attempt to repair or replace any boiler parts yourself, unless it is specifically indicated in this manual. All maintenance and/or repair operations must be carried out by a Technical Assistance Service authorised by NAVIEN. – Make sure you unplug the boiler from the electrical mains before opening the front cover. – To prevent scalding, check the water temperature as you are using the boiler. – DO NOT change the DHW temperature while someone is using the boiler. – All accessories and spares used with the boiler must be those supplied by NAVIEN. – DO NOT use the boiler if it shows signs of abnormal functioning. – DO NOT allow children to use or tamper with the boiler. 2.3. EC Conformity Mark NAVIEN, hereby declares that the boiler models: NCN CE 21K (A), NCN CE 25K(A) , NCN CE 32K(A) , NCN CE 37K(A) to which this declaration refers, conform to and comply with the essential requirements of the following applicable European Standards and Directives: Gas appliances: Directive 2009/142/EC Standards EN 483, EN 437, EN 625 and EN 677 Boiler Efficiency: Directives 92/42/EEC and 93/68/EEC Standards EN 483 Low voltage: Directives 73/23/EEC and 93/68/EEC Standards EN 60335-1, EN 60335-2-30, EN 60335-2-51, EN 50165 Electro-magnetic Compatibility: Directive 2004/108/EC Standards EN 55014 Pressure Vessels: Directive 97/23/EEC NAVIEN, manufactures its products using a Quality Assurance system in compliance with Standard EN-ISO 9001:2000. 2.4. Start-up and adjustment WARNING The installation must be made by a qualified authorised installer in compliance with applicable national regulations and standards and any other local regulations that may apply. Start-up, adjustment, repair and any maintenance operations must only be carried out by an authorised TAS technician. If the boiler is installed in a small compartment, DO NOT obstruct any of the air intakes or fume extraction ducts, and ensure sufficient space is left around the boiler for maintenance operations to be carried out and to ensure sufficient ventilation. 2.5. In case of emergency DANGER Boiler malfunctioning may cause gas leaks and the risk of smelling gas, explosion and asphyxia due to carbon monoxide inhalation. If you smell gas: – DO NOT smoke. – Avoid any flames or sparks. – DO NOT turn any light switches or electrical appliances on or off. – Open doors and windows. – Turn off the main gas supply valve. – Turn off all components of the heating system. – Keep all persons away from the hazard area. – Carefully follow the safety instructions indicated by the gas supplier and locate the gas meter. – Notify the boiler installer of the incident, from outside the building or hazard area. DANGER Fume extraction system – FAILURE TO FOLLOW the fume extraction system installation instructions given in this manual can affect boiler operating safety. To prevent risk of fire, explosion or asphyxia due to carbon monoxide, never start-up the boiler unless you are sure there is sufficient outdoor ventilation in the premises on which it is installed. – It is recommended for the fume extraction terminal and the air intake duct to be inspected yearly, to ensure correct combustion. – Switch off the boiler immediately and DO NOT use it if you observe any damage, seals coming apart, cracks, corrosion or dents in any of the ventilation pipes, the flue and/or the air intake duct. WARNING – Faulty installation of the boiler combustion gas removal and air intake system can cause a sudden increase in carbon monoxide emissions (CO). Inhaling carbon monoxide can cause severe brain damage or death. Carefully read and follow the installation instructions to this effect. – Protect the boiler combustion gas outlet and air intake terminal against obstruction due to accumulation of snow, dirt, dead leaves, weeds, etc. 2.6. Modifications The user must NOT modify or tamper with any of the following boiler installation aspects, under any circumstances: – Any part of the inside of the boiler. – The gas, water or electricity supply installation. – The combustion gas removal system. – The combustion air intake system. – The boiler safety valve. – Any installation safety devices. No building alterations must be made near the boiler that could affect its operating safety or correct functioning. DO NOT break or remove any sealing element of any component of the boiler. These components may only be handled by authorised personnel or official TAS technicians. 2.7. Water leaks It is recommended to check regularly the installation water’s pressure, indicated on the control panel display. If recurrent pressure drops are observed, there may be a leak in the installation. In such cases, contact your nearest Official TAS. If you observe any water leakage from any of the installation pipes between the boiler and the hot water taps, turn off the general cold water valve of the home and contact an installer to repair the leak as soon as possible. |
