INSERTO 60 – 70 – 70 To – 70 Pr – 70 H4926 6090710 – EN14.3. CLEANING OF THE ASHAll the appliances 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 is suggested to leave always 3-4 cm of ash in the hearth.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 off andcomplete cooling.Check the external air intake, by cleaning it, at least once a year. The stack must be regularly swept by the chimneysweeper. Let your chimney sweeper in charge of your area check the regular installation of the appliance, theconnection to the stack and the aeration.15. SUMMER TIMEAfter having performed the cleaning of the hearth, of the stack and of the flue, by removing completely the ash andother possible residuals, close all hearth doors and related registers.It is suggested to perform the flue cleaning at least once a year; in the meantime, verify the actual state of the doorseals, which do not assure the good operation of the appliance, if they are not completely integral (i.e. if they do notadhere anymore to the door)! Therefore, it is necessary to replace them.In case of humidity of the room where the appliance is located, place the absorbing salts within the hearth.Protect the internal cast iron parts with neutral Vaseline, if you wish to keep the aesthetic appearance unchanged intime.16. CALCULATION OF THE THERMAL POWER.There is not an absolute rule for calculating the correct necessary power. This power is given according to the spaceto be heated, but it depends also largely on the insulation. On an average, the calorific value necessary for a properlyinsulated room is 40 kCal/h per m3 (for an external temperature of 0 °C).Given that 1 kW corresponds to 860 kCal/h, it is possible to adopt a value of 50 W/m3.Let’s suppose that one wishes to heat a room of 150 m3 (10 x 6 x 2.5 m) in an insulated apartment, it is necessary tohave 150 m3 x 50 W/m3 = 7500 W or 7.5 kW.Therefore as main heating, a 10 kW appliance is sufficient.Approximate combustion value Quantity required for 1 kgof dry woodFuel Unit kCal kWDry wood (15% humidity) kg 3600 4.2 1.00Wet wood (50% humidity) kg 1850 2.2 1.95Wood briquettes kg 4000 5.0 0.84Brown coal briquettes kg 4800 5.6 0.75Normal anthracite kg 7700 8.9 0.47Coke kg 6780 7.9 0.53Natural gas m3 7800 9.1 0.46Naphtha L 8500 9.9 0.42Electricity kW/h 860 1.0 4.19
