ENgLIsH
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 sufcient.

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSES POSSIBLE SOLUTIONS
The frame of
the cooker or
its parts change
colour
Flue draught pressure too high
Clean the surfaces;
Contact the chimney sweep for a possible installation of a throttle
valve;
Bended oven
and chipped
enamel
Flue draught pressure too high
Small enamel chips do not compromise the correct functioning of the
appliance. In case of major damages contact the Customer Service.
Contact the chimney sweep for a possible installation of a throttle
valve
Rust on the
stainless steel
cooking plate
A slight coat of rust on the whole
surface of the cooking plate
may depend on wet air (cooking
steam)
Grind the surface;
Only when the plate is cold, grease the surface with non acid grease
(vaseline or paraffin oil);
Only when the plate is lukewarm, clean with a soft cloth
CLEANING OF THE COLLECTION CASING COOKING through the oven
The smokes collection casing can be cleaned either through the oven (remove the horizontal sheet metal which is the base of the
oven See Picture 11) the cooker or from the top.
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.
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.
