CLEANING OF THE COLLECTION CASING COOKING with under door oven

The smokes collection casing can be cleaned either through the door which is under the oven
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.
Pay ATTENTION that after cleaning all dismounted parts are reinstalled hermetically.

CAST IRON COOKING PLATE AND RINGS

IMPORTANT: to avoid rust DO NOT forget pots or pans on the cold cooking plate. This would create rust rings, unpleasant
to see and difficult to remove.
The cast iron cooking plate and the cast iron rings needs to be periodically cleaned by using sandpaper (grain 150) without
touching the enamelled parts..
To carry out the cleaning operation remove the smoke outlet spigot and the smoke pipe. The smoke compartment can be cleaned
from the front side of the oven (see chap. CLEANING SMOKE COMPARTMENT COOKERS) or from the top. In this case remove the
cast iron rings and the cooking plate, as well the smoke outlet spigot and the smoke pipe. The cleaning can be carried out by using
a brush and a hoover.
(Where existing STANLESS STEEL frame) Once you have placed the cast iron cooking plate, make sure to have always 3 mm in-
between the cooking plate and the STAINLESS STEEL frame. This gap is important because of the thermal expansions and to
avoid chromatic changes of the STAINLESS STEEL frame when hot.
ATTENTION: once the cleaning operations are terminated all the parts have to be re-assembled hermetically.

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 (for an external temperature of 0°C).
3
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
150 m x 35 W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
