After cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearth
and the relevant registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work
others possible appliances connected to the same flue.

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
(for an external temperature of 0°C).

given that 1 kw corresponds to 860 kcal/h, it is possible to adopt a value of 35 w/m
Let's suppose one wishes to heat a room of 150 m
150 m x 35 w/m = 5250 w or 5,25 kw. As main heating, a 8 kw device is therefore sufficient.
