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.
CLEANINg OF THE TEMOCOOkINg COLLECTION CAsINg THROUgH THE OVEN
The smokes collection casing can be cleaned either through the oven
It will be necessary to carefully clean the exchange surfaces removing the movable part of the hob and scraping the exchange surfaces of the
furnace and the pipes which compose the tube bundle located above the oven, as well as the downward passage of the smoke on the right
side of the oven. Later clean the smoke passage under the oven. 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.
MAINTENANCE ON THE WATER sYsTEM
Excessive incrustation deposits on the inner walls of the hearth considerably reduce the efficiency of heat exchange; therefore,
remove these deposits using a steel brush whenever necessary. Never use corrosive substances that can damage the thermo-
fireplace and the boiler.
With the system switched off, once a year carry out the following checks:
• Check the operation and efficiency of the blowdown and safety valves. If they are defective, contact your authorised installer. IT Is
sTRICTLY FORBIDDEN TO REMOVE OR TAMPER WITH THE sAFETY DEVICEs.
• Check the thermal insulation of the filling pipe and the safety pipe.
• Make sure that the system is filled and under pressure, checking the water level in the expansion tank; also check that it is working
properly and check the efficiency of the safety pipe.
