Summer Stop; Calculation Of The Thermal Power - Nordica 50 Mode D'emploi

During the cleaning, it is necessary to remove the ash drawer, the grating, and the smoke deflectors from the device in order to ease
the fall of the soot. The deflectors can be easily extracted from their seats since they are not fastened using screws. Once the clearing
has been carried out, place them back in their seats
CAUTION: The lack of the deflectors causes a strong depression, with a too fast combustion, an excessive
consumption of wood with related overheating of the device.

SUMMER STOP

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.
We suggest performing the cleaning operation of the flue at least once per year; verifying in the meantime the actual status of the rope
seals, which cannot ensure the good operation of the equipment if they are not in good condition and are not making a good seal! In
this case 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.

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 (for an external temperature of 0°C).
3
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.
