GIULIETTA – ISETTA-07 – ISOTTA-07
Before opening the hearth door, open the ignition control (C), load the fuel, close the door and after about 5
or 10 minutes close the control (C).
With the registers placed on the front of the appliance it is adjusted the emission of heat of the stove. They
must be opened according to the calorific need. The best combustion (with minimum emissions) is reached
when, loading the wood, most of the air for the combustion passes through the register of secondary air.
Never overload the stove (compare the technical table - max. quantity of loadable fuel).
Too much fuel and too much air for the combustion may cause overheating and then damage the
stove, as a consequence some scratches in the lower front part of the stove could happen.
The warranty does not cover the damages due to overheating of the equipment.
You should always use the stove with the door closed in order to avoid damages due to overheating (forge
effect).
The adjustment of the registers, necessary to obtain a rating calorific performance with a depression on the
chimney is the following:
FUEL
Wood
Mass of fuel hourly
Besides by the adjustment of air for the combustion, the intensity of combustion and then the calorific value
of your stove is affected by the chimney. A good flue of the chimney requires a more reduced adjustment of
air for the combustion, while a poor flue needs more an exact adjustment of air for combustion.
To verify the good combustion of the stove, check if the smoke coming out from the chimney is transparent.
If it is white, it means that the stove is not correctly adjusted or the wood is too wet; if on the contrary the
smoke is grey or black, it means that the combustion is not complete (it is necessary a greater quantity of
secondary air).

OPERATION IN TRANSITION PERIODS

During transition periods when the external temperatures are higher, if there is a sudden increase of
temperature it can happen that the combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more
frequently and increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit a
rapid burning (growing up of the flames) and the stabilization of the draught.
Then, check that all openings for the cleaning and the connections to the stack are air-tight. In case of
doubt, do not operate the stove.

MAINTENANCE AND CARE

Let the installation of your stove, the connection to chimney and the ventilation check by your chimney
sweeper.
For the cleaning of enamelled surfaces use soap water or not aggressive and not chemically abrasive
detergents.
IMPORTANT: It is possible to use exclusively spare parts clearly authorized and offered by LA
NORDICA. In case of need please apply to your dealer!
THE APPLIANCE CAN NOT BE MODIFIED!
12.1

CLEANING OF THE FLUE

A correct lighting, the burning of a proper fuel, the loading of the suggested quantity of fuel, the right
adjustments of the secondary air control, the sufficient draught of the chimney and the presence of air for
the combustion, are essential for the good operation of the appliance.
The appliance should be completely cleaned at least once a year or every time it is needed (in case of bad
working and low yield).The cleaning must be carried out exclusively with cold equipment.
