ATTENTION: Only use the grease in the La Nordica syringe.

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.

SUMMER SET ASIDE
ATTENTION: the installation must be kept constantly full of water even in periods in which the use of
thermo-fireplaces is not required. During winter time, inactivity must be faced by adding antifreeze
substances.
After cleaning the hearth, the chimney, and the flue, removing all ashes and any other residues, close all
the doors of the hearth and the respective registers.
We recommend that the flue be cleaned at least once a year. In the meantime, check the condition of the
door seals; if they are not perfectly integral (i.e. no longer adhering to the door), they will not guarantee the
proper operation of the appliance and therefore must be replaced.
In case of dampness in the room where the appliance is installed, scatter some absorbent salts inside the
hearth.
To maintain the aesthetic appearance over time, protect the inside parts in cast iron with vaseline.
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.

DETERMINING THE HEATING POWER
There is no sure-fire rule for calculating the correct power necessary. The heating power depends on the
space to be heated, but also in large part on the insulation. On average, the heating power necessary for
an adequately insulated room is 40 kcal/h per m
Since 1 kW corresponds to 860 kcal/h, we can adopt the value of 50 W/m
Supposing that you wish to heat a room of 150 m

150 m
x 50 W/m
= 7500 W or 7.5 kW. As the main heating source, a 10 kW appliance will therefore be
sufficient.
