13.12. 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.
- 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.

13.13. CLEANING OF THE COLLECTION CASING COOKING through the oven

The smokes collection casing can be cleaned either through the oven (remove the horizontal sheet metal which is the base of the oven
See Picture 9 at page 67) the cooker or from the top.
To this purpose remove the circles of the cooking plate and disassemble the smokes pipe from the exhaust small trunk. Cleaning can be
made with a brush and a vacuum cleaner.
IMPORTANT: please verify that the deflectors are set as indicated in the Picture.
Pay ATTENTION that after cleaning all dismounted parts are reinstalled hermetically.

14. 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.
