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.

ROUTINE MAINTENANCE PERFORMED BY QUALIFIED TECHNICIANs

Routine maintenance must be performed at least once a year.
Using wood as solid fuel, the generator requires annual routine maintenance, which must be performed by a qualified technician, using
only original spare parts.
Failure to comply can jeopardise the safety of the appliance and make the warranty null and void.
Respecting the frequencies of cleaning reserved for the user described in the use and maintenance manual, the generator is guaranteed
correct combustion over time, preventing any anomalies and/or malfunctioning that could require more interventions of the technician.
Requests for routine maintenance are not contemplated in the product warranty.

gAskETs

The gaskets guarantee the tightness of the stove and its consequent good functioning.
They must be controlled periodically. They must be replaced immediately if they are worn or damaged.
These operations must be carried out by a qualified technician.

CONNECTION TO THE FLUE

Vacuum and clean the pipe that leads to the flue yearly or any time that it is necessary. If there are horizontal tracts, the residue must be
removed before it can prevent the passage of the fumes.

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.
