NORMA IDRO DSA7197130 - IT-EN-DE-FR 23If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that thecombustion is not complete (it is necessary a greater quantity of secondary air).10.1. USE OF THE OVEN (If present)Thanks to the air flow for the combustion, the temperature of the oven may become remarkably affected. A sufficient flue of the chimneyand of the channels, well cleaned for the flow of burning smokes around the oven are fundamental for a good cooking result. The oven panmay be located on different plans. Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and biscuits must reachthe medium level. The upper level may be used to heat or grill.10.2. ELECTRICAL POWER SUPPLY FAILUREIn the event of an unexpected electrical power supply failure during normal system operation, it will be necessary to carry out these simplemanoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack of pump operation.1. Raise the moveable furnace grill (if present ) to the highest level in order to reduce the exchange surface exposed to the heat of theflame.2. Close the primary and secondary air registers in addition to turning the thermostat to 0 ( if present).3. Open the oven door (if present) in order to favour the elimination of the internal heat.4. Open the flue gas register ; in this way, it will deviate the residual heat still produced towards the chimney.10.3. OPERATION IN TRANSITION PERIODSDuring transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that thecombustion gases inside the flue cannot be completely sucked up.The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the airfor the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the flames) and the stabilizationof the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tigh.In case of doubt, do not operate the product.ATTENTION: never light for any reason if the installation is not completely full of water in order to avoid a serious damage of the wholestructure. The installation must always be full of water even when the thermo-fireplace is not used. A possible no use during winterseason must be faced by adding antifreeze substances.10.4. SUMMER USEThe system must be completely filled with water. The absence of water in the system would lead to serious damage of the entirestructure. ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water; doing this wouldlead to serious damage of the entire structure.In order to prevent water boiling, the circulation pump must be always in function in order to drain on the radiators, or on the puffer, or onany other thermal absorption structure the heat given from the boiler to the water. If the pump does not circulate or for any reason thewater temperature exceeds 95°C, acts the DSA valve discharging heat in the throughway water. It is recommended to supervisethe water temperature in the thermoproduct during summer use to avoid recurrent interventions of the DSA valve which mayjeopardize its good operation.11. SUMMER STOPAfter cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearthand the relevant registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work otherspossible appliances connected to the same flue.We suggest performing the cleaning operation of the flue at least once per year; verifying in the meantime the actual status of the ropeseals, which cannot ensure the good operation of the equipment if they are not in good condition and are not making a good seal! In thiscase the seals must be replaced.In presence of dampness in the room where the stove has been placed, we advise you to put absorbent salts into the hearth.If you want to keep for long the aesthetic look of the cooker it is important to protect its internal walls in row cast iron with neutral Vaseline.Check the water level in the expansion tank and remove any air from the system by bleeding the radiators; also check to make sure thatthe plumbing and electrical accessories (control unit, circulator) are working properly.ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water; doing this would lead toserious damage of the entire structure. The installation must always be full of water even when the thermo-fireplace is not used.
