TERMOROSSELLA PLUS DSA / FORNO DSA – TERMONICOLETTA DSA / FORNO DSA7197100 - IT - EN - DE - FR 2310. 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: You should only use spare parts approved and supplied by La NORDICA. Please contact your specialized retailer if yourequire spare parts.YOU MUST NOT MAKE ANY CHANGES TO THE DEVICE!!!10.1. 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 who cansimultaneously perform an audit of the flue (checking of possible deposits).Excessive 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-product andthe boiler.During the cleaning, it is necessary to remove the ash drawer, the grating, and the smoke deflectors from the device in order to ease thefall of the soot.The deflectors can be easily extracted from their seats since they are not fastened using screws. Once the clearing has been carried out,place them back in their seats.CAUTION: The lack of the deflectors causes a strong depression, with a too fast combustion, an excessive consumption of woodwith related overheating of the device.10.2. 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.10.3. CLEANING OUT THE ASHESAll the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes (Picture 7 at page 56 pos. A).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.10.4. MAINTENANCE ON THE WATER SYSTEMWith 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.• Check the thermal insulation of the filling pipe and the safety pipe.• Make sure that the system is filled and under pressure, checking the water level in the expansion tank; also check that it is workingproperly and check the efficiency of the safety pipe.
