Operation In Transition Periods; Summer Use - LA NORDICA NORMA S EVO IDRO DSA Manuel Utilisateur

2. Close the primary and secondary air registers in addition to turning the thermostat to 0 ( if present).
3. Open the oven door (if present) in order to favour the elimination of the internal heat.
4. Open the flue gas register ; in this way, it will deviate the residual heat still produced towards the chimney.

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-tigh.
In case of doubt, do not operate the product.
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.

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 appliance during summer use to avoid recurrent
interventions of the DSA valve which may jeopardize its good operation.
