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).
11. POWER CUT
In the eventuality of a sudden power cut during normal functioning of the system, the following simple manoeuvres
must be performed to prevent the thermoheating stove boiling due to the pump not functioning.
1.
Close the primary and secondary air regulators completely in a way to suffocate the flame as much as
possible.
2.
Close the fumes regulator, if present, in order to further limit the flow of combustion air through any
slots.
12. FUNCTIONING IN TRANSITION PERIODS
ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water;
doing this would lead to serious damage of the entire structure.
The system must be kept constantly full of water even during the periods when the use of the thermoheating stove is
not requested. During the winter, inactivity must be faced with the addition of antifreeze.
During the transition period when the outdoor temperature are higher, in case of sudden temperature increasing it
could be that the flue had some problems and that the fumes are not totally aspirated. There may be a certain
difficulty in discharging the fumes (intense smell of gas).
In this case frequently shake the grid and increase the combustion air. Then, load a reduced quantity of fuels which
allows a quick burning (by developing flames) and therefore stabilise the flue draught. Check that all openings for
cleaning and connections to the chimney are hermetic.
12.1.
USE AS A NORMAL STOVE.
ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water;
doing this would lead to serious damage of the entire structure.
Use as a normal stove is
NOT envisioned!
In order to prevent water boiling in the boiler, when the thermoheating stove is in function, the circulation pump must
be in function in order to dispose of the heat given to the boiler water on the radiators.
The system must be kept constantly full of water even in period when use of the thermoheating stove is not
requested. During the winter, inactivity must be faced with the addition of antifreeze.
13. 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!
13.1.
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.
This operation should be carried out by a chimney sweeper who can simultaneously perform an audit of the flue
(checking of possible deposits). During the cleaning, it is necessary to remove from the appliance the ash drawer
and the smokes pipes. It is possible to clean the space for the collection of smokes from the hearth or through the
smoke exhaust, by using a brush and a vacuum cleaner.
Once the cleaning has been completed, the same has
to be positioned back in its seat.
13.2.
CLEANING OF THE GLASS
Thanks to a specific entry of the secondary air the building of deposit on the glass of the door is slowed down in a
remarkable way. However the building of this deposit cannot be avoided with the use of solid fuels such as wet wood,
and this is not to be considered as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold appliance to
avoid the explosion of the same. Do not use cloths, abrasive or chemically aggressive products by cleaning the
hearth glass.
