INSERTO Crystal 50 – 50 VERTICALE – 70 – 80 – 1006096801 - Rev.09 – EN 2915. 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 for1 kg of 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 |
