ELECTRICAL POWER SUPPLY FAILURE

In the event of an unexpected electrical power supply failure during normal system operation, it will be necessary to carry out these simple
manoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack of pump operation.
• Close completely the primary and secondary air registers in order to smother the flame as much as possible.
• Close the smokes register, if existing, to limit further coming of combustive air through possible cracks.
8.2.

OPERATION DURING 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 thermo-fireplace.
ATTENTION: never light for any reason if the installation is not completely full of water in order to avoid a serious damage of the whole
structure. The installation must always be full of water even when the thermo-fireplace is not used. A possible no use during winter season
must be faced by adding antifreeze substances.
8.3.

SUMMER USE

The system must be completely filled with water. The absence of water in the system would lead to serious damage of the entire
structure. 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.
In order to prevent water boiling, the circulation pump must be always in function in order to drain on the radiators, or on the puffer, or on
any other thermal absorption structure the heat given from the boiler to the water. If the pump does not circulate or for any reason the
water temperature exceeds 95°C, acts the DSA valve discharging heat in the throughway water. It is recommended to supervise
the water temperature in the thermoproduct during summer use to avoid recurrent interventions of the DSA valve which may
jeopardize its good operation.

9. SUMMER TIME

After having performed the cleaning of the hearth, of the stack and of the flue, removing completely the ash and other possible residuals,
close all doors of the hearth and the related registers.
It is suggested to perform the flue cleaning at least once a year; in the meantime, verify the actual state of the door seals, which do not
assure the good operation of the device, if they are not completely integral (i.e. if they do not adhere anymore to the door)! Therefore, it is
necessary to replace them.
In case of humidity of the room where the device is located, place the absorbing salts within the hearth.
To maintain the aesthetic appearance over time, protect the inside parts in cast iron with Vaseline.
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 installation must always be full of water even when the thermo-fireplace is not used.
Check the water level in the expansion tank and remove any air from the system by bleeding the radiators; also check to make sure that
the plumbing and electrical accessories (control unit, circulator) are working properly.

10. MAINTENANCE AND CARE

Check the external air intake, by cleaning it, at least once a year. The stack must be regularly swept by the chimney sweeper.
Let your chimney sweeper in charge of your area check the regular installation of the device, the connection to the stack and the aeration.
IMPORTANT: The maintenance must be carried out only and exclusively with cold device .You should only use spare parts approved
and supplied by La NORDICA S.p.A. . Please contact your specialized retailer if you require spare parts. YOU MUST NOT MAKE
ANY CHANGES TO THE DEVICE!!!

10.1. GLASS CLEANING

Thanks to a specific inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with efficacy. Nevertheless this
can never be avoided by using solid fuels ( particularly wet wood ) and it has not to be understood as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold device to avoid the explosion of
the same. For the cleaning, it is possible to use specific products or a wet newspaper paper ball passed in the ash to rub it. Do not
use cloths, abrasive or chemically aggressive products by cleaning the hearth glass.
The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough
draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance and
for the cleaning of the glass.
BREAK OF GLASSES: Given that the glass-ceramic glasses resist up to a heat shock of 750°C, they are not subject to thermal
shocks. Their break can be caused only by mechanic shocks (bumps or violent closure of the door, etc.). Therefore, their
replacement is not included in the warranty.

10.2. CLEANING OUT THE ASHES

All the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes.
It is suggested to empty periodically the ash drawer and to avoid it fills completely in order not to overheat the grating. Moreover, it is
suggested to leave always 3-4 cm of ash in the hearth.
CAUTION: The ashes removed from the hearth have to be stored in a container made of fire-resistant material equipped with an
air-tight cover. The container has to be placed on a fire-resistant floor, far from flammable materials up to the switching off
and complete cooling.
