NORMA IDRO DSA24 7197130 - IT-EN-DE-FR12. MAINTENANCE AND CARECheck the external air intake, by cleaning it, at least once a year. The stack must be regularly swept by the chimney sweeper.Let your chimney sweeper in charge of your area check the regular installation of the device, the connection to the stack and the aeration.IMPORTANT: The maintenance must be carried out only and exclusively with cold device . You should only use spare parts approvedand supplied by La NORDICA. Please contact your specialized retailer if you require spare parts. YOU MUST NOT MAKE ANY CHANGESTO THE DEVICE!!!12.1. MAJOLICASLa NORDICA has chosen majolica tiles, which are the result of high-quality artisan work. As they are completely carried out by hand, themajolica may present crackles, speckles, and shadings. These characteristics certify their precious origin.Enamel and majolica, due to their different coefficient of dilatation, produce microcrackles, which show their authentic feature.For the cleaning of the majolica we suggest you to use a soft and dry cloth; if you use a detergent or liquid, the latter might soak in andmake the crackles more visible.12.2. PRODUCTS MADE OF NATURAL STONENatural stone has to be cleaned with very thin abrasive paper or with an abrasive sponge. Do NOT use any cleanser or fluid.12.3. VARNISHED PRODUCTSAfter some years of product use a change in the varnished details colour is totally normal. This is due to the considerable temperaturerange the product is subject to whenever in use and to the varnish ageing of time passing by.ATTENTION: before any possible application of the new varnish, do clean and remove all the traces from the surface which has to bevarnished.12.4. ENAMELLED PRODUCTSFor the cleaning of enamelled surfaces use soap water or not aggressive and not chemically abrasive detergents.After the cleaning do NOT let soapy water or any cleanser dry but remove them immediately.12.5. CHROMIUM-COMPONENTSIf the components become bluish due to overheating, this can be solved with a suitable product for cleaning. DO NOT use abrasives orsolvents.12.6. GLASS CLEANINGThanks to a specific inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with efficacy. Nevertheless thiscan never be avoided by using solid fuels ( particularly wet wood ) and it has not to be understood as a defect of the appliance.IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold device to avoid the explosion ofthe same. For the cleaning, it is possible to use specific products or a wet newspaper paper ball passed in the ash to rub it. Do notuse cloths, abrasive or chemically aggressive products by cleaning the hearth glass.The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enoughdraught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance andfor the cleaning of the glass.BREAK OF GLASSES: Given that the glass-ceramic glasses resist up to a heat shock of 750°C, they are not subject to thermalshocks. Their break can be caused only by mechanic shocks (bumps or violent closure of the door, etc.). Therefore, theirreplacement is not included in the warranty.12.7. CLEANING OUT THE ASHESAll the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes.It is suggested to empty periodically the ash drawer and to avoid it fills completely in order not to overheat the grating. Moreover, it issuggested to leave always 3-4 cm of ash in the hearth.CAUTION: The ashes removed from the hearth have to be stored in a container made of fire-resistant material equipped with anair-tight cover. The container has to be placed on a fire-resistant floor, far from flammable materials up to the switching offand complete cooling.12.8. CLEANING THE FLUEThe correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enoughdraught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.The device should be completely cleaned at least once a year or every time it is needed (in case of bad working and low yield). Anexcessive deposit of soot can cause problems in the discharge of smokes and fire in the flue.The cleaning must be carried out exclusively with cold equipment. This operation should be carried out by a chimney sweeper whocan simultaneously perform an audit of the flue (checking of possible deposits).12.9. MAINTENANCE ON THE WATER SYSTEMExcessive incrustation deposits on the inner walls of the hearth considerably reduce the efficiency of heat exchange; therefore, removethese deposits using a steel brush whenever necessary. Never use corrosive substances that can damage the thermo-fireplace andthe boiler.With the system switched off, once a year carry out the following checks:• Check the operation and efficiency of the blowdown and safety valves. If they are defective, contact your authorised installer. IT ISSTRICTLY FORBIDDEN TO REMOVE OR TAMPER WITH THE SAFETY DEVICES.
