14. CALCULATION OF THE THERMAL POWER

There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the calorific value necessary for a properly insulated room is 30 kcal/h per m
an external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 38 W/m
Let's suppose one wishes to heat a room of 150 m
x 38 W/m = 5700 W or 5,7 kW. As main heating, a 8 kW device is therefore sufficient.

POSSIBLE SOLUTIONS

™ Clean the surfaces;
™ Contact the chimney sweep for a possible installation of a throttle valve;
™ Small enamel chips do not compromise the correct functioning of the appli-
ance. In case of major damages contact the Customer Service.
™ Contact the chimney sweep for a possible installation of a throttle valve
™ Grind the surface;
™ Only when the plate is cold, grease the surface with non acid grease
(vaseline or paraffin oil);
™ Only when the plate is lukewarm, clean with a soft cloth
