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.
MAJOLICAs (IF PREsENT)
La NORDICA has chosen majolica tiles, which are the result of high-quality artisan work. As they are completely carried out by hand, the
majolica may present crackles, speckles, and shadings. These characteristics certify their precious origin.
Enamel and majolica, due to their different coefficient of dilatation, produce microcrackles, which show their authentic feature.
For the cleaning of the majolica we suggest you to use a soft and dry cloth; if you use a detergent or liquid, the latter might soak
in and highlight the crackles permanently.
PRODUCTs MADE OF NATURAL sTONE (IF PREsENT)
Natural stone has to be cleaned with very thin abrasive paper or with an abrasive sponge. Do NOT use any cleanser or fluid.
VARNIsHED PRODUCTs (IF PREsENT)
After some years of product use a change in the varnished details colour is totally normal. This is due to the considerable temperature range
the product is subject to whenever in use and to the varnish ageing of time passing by.
ATTENTION: before any possible application of the new varnish, do clean and remove all the traces from the surface which has to
be varnished.
ENAMELLED PRODUCTs (IF PREsENT)
For the cleaning of enamelled surfaces use soap water or not aggressive and not chemically abrasive detergents.
After the cleaning do NOT let soapy water or any cleanser dry but remove them immediately.
DO NOT use sandpaper or steel wool.
CHROMIUM-COMPONENTs (IF PREsENT)
If the components become bluish due to overheating, this can be solved with a suitable product for cleaning. DO NOT use abrasives or
solvents.
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
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
W/m
= 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
