MAX - JUNIOR / MAJOR - MINOR

12.4. 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.

12.5. 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.

12.6. 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.

12.7. 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.

12.8. 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.

13. 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 35 W/m
Let's suppose one wishes to heat a room of 150 m
x 35 W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
