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: Considering that the glasses are manufactured in glass-ceramic and resistant to heat
shock up to 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.

CLEANING OF THE ASH DRAWER
All chimney stoves of La NORDICA have a hearth grate and an ash
drawer for the collection of ashes (Picture 10 – A ).
We suggest you to empty periodically the ash drawer and to avoid
filling it up totally, in order not to overheat the grate. Furthermore,
we recommend letting always 3-4 cm's of ash in the hearth.
ATTENTION : 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.

MAINTENANCE ON THE WATER SYSTEM
With the system switched off, once a year carry out the following checks:
•
Check the operation and efficiency of the blowdown and safety valves. If they are defective, contact your
authorised installer. IT IS STRICTLY FORBIDDEN TO REMOVE OR TAMPER WITH THE SAFETY
DEVICES.
•
Check the thermal insulation of the filling pipe and the safety pipe.
•
Make sure that the system is filled and under pressure, checking the water level in the expansion tank; also
check that it is working properly and check the efficiency of the safety pipe.
14. SUMMER STOP
ATTENTION: 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.
After you have cleaned the hearth, the chimney and the flue, trying to eliminate completely the ash and others
residuals, you must close the doors of the hearth and its registers; in case you disconnect the appliance from the
chimney, close its opening in order to let work other possible appliances connected to the same flue.
The cleaning of the flue should be done at least once a year; in the meanwhile check the state of the gaskets, which if
not perfectly intact, that is to say that they are not more close-fitting with the stove, do not guarantee the good working
of the stove! In that case the gaskets must be replaced.
In presence of dampness in the room where the stove has been placed, we advise you to put absorbent salts into the
hearth.
15. CONNECTING A CHIMNEY OR OPEN FURNACE TO THE FLUE
The smoke channel is the section of tube that connects the product to the flue, in the connection these simple but
very important principles must be followed:
•
for no reason must the smoke channel be used with a diameter lower than that of the neck of the outlet with
which the product is fitted;
•
each metre of horizontal route of the smoke channel causes a small leak of charge which should be
compensated for by raising the flue;
•
the horizontal section must never be higher than 2 m (UNI 10683-2005);
•
each bend of the smoke channel considerably reduces the draught of the flue which must be compensated
for by raising it suitably;
•
the UNI 10683-2005 Regulation –Italy requires that the bends or variations of direction must in no case be
greater than 2 including the emission into the flue.
Wanting to use the flue of a chimney or open furnace, it will be necessary to close the hood hermetically below the
inlet point of the smoke channel pos. A Picture 11.
