CLEANING OF THE TEMOCOOKING COLLECTION CASING THROUGH THE OVEN
The smokes collection casing can be cleaned either through the oven (Picture 10) the cooker or from the top.
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 deectors 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 eciency of heat exchange; therefore,
remove these deposits using a steel brush whenever necessary. Never use corrosive substances that can damage the thermo-
replace and the boiler.
With the system switched o, once a year carry out the following checks:
Check the operation and eciency 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 lling pipe and the safety pipe.
Make sure that the system is lled and under pressure, checking the water level in the expansion tank; also check that it is working
properly and check the eciency of the safety pipe.
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 caloric value necessary for a properly insulated room is 30 kcal/h per m
3
(for 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
3
.
Let’s suppose one wishes to heat a room of 150 m
3
(10 x 6 x 2.5 m) in an insulated apartment. In this case, it is necessary to have 150 m
3
x 35
W/m
3
= 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sucient.
