13.9. 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 (cookers) and the cast iron rings (cookers - stoves) needs to be periodically cleaned by using sandpaper (grain
150) without touching the enamelled parts..
- (Cookers) 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.
- (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.

13.10. CLEANING OF THE TermoCOOKING COLLECTION CASING with under door oven

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

13.11. 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.

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 38 W/m
Let's suppose one wishes to heat a room of 150 m
x 38 W/m = 5700 W or 5,7 kW. As main heating, a 8 kW device is therefore sufficient.
