Products Made Of Natural Stone (If Present); Varnished Products (If Present); Enamelled Products (If Present); Chromium-Components (If Present) - LA NORDICA FULVIA Manuel Utilisateur

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.

MAINTENANCE OF THE OVEN (WHERE EXIsTINg)

To avoid the possible forming of rust it is recommended:
- To let the steam getting out of the oven to reduce the formation of any condensation by opening the door briefly and carefully (1 or 2
times, or more often in case of cooking food very humid and with longer cooking times);
- Remove the food from the oven once cooked. Letting the food to chill in the oven at a temperature below 150 °C results in the forming of
condensation;
- After cooking, leave the oven door partially open to dry out any condensation;
- In case humidity formed inside the oven, we suggest you to treat with neutral vaseline the inside part of the cast iron door (where existing).
- Repeat the treatment with the neutral vaseline on the inside part of the cast iron door every 3-6 months, depending of the frequency of
the use of the oven;
- In case of presence of rust on the inside part of the cast iron door, remove the rust by using abrasive material and then treat the cast iron
surface with neutral vaseline.
In order to ensure the quality of the foods that are cooked in the oven, the internal parts of the cast iron doors have NOt been treated with any
product.

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.
