that the pressure is reaching 1 bar (this is required only
for systems with closed vase, you have to look for local
rules that allow it); whereas for systems with open vase
the restoration will be automatic;
• Close the fi lling tap of the system and then let the air
fl ow out again through the vent's valve of the radiator;
Water Characteristics
The characteristics of the water used to fi ll the system
are very important to prevent the build-up of mineral salts
and the formation of incrustations along the pipes, in the
thermostove and in the heat exchangers.
Therefore, please get your plumber's advice concering:
• Hardness of water circulating in the system, to prevent
problems of incrustation and limescale, especially in the
domestic water heat exchanger (>15° French).
• Installation of a water softener (if water hardness > 15°
French).
• Filling the system with treated water (demineralised).
If you have very extensive system, with a large amount of
water, or which require frequent refi lling, it is recommended
the installation of water softening system. It 'should
be noted that the encrustations drastically reduce
performance because of their low thermal conductivity.
Pellet
The pellets are cylinders of compressed wood, produced from sawdust and wood processing (chips and
sawdust), generally produced by sawmills and carpenters. The binding capacity of the lignin contained
in wood, allows to obtain a compact product without adding additives and foreign chemicals to the
wood, is therefore obtained a natural fuel with high yield.
The use of expired pellets or any other unsuitable material can damage parts of the
thermostove and impair proper operation: this can lead to the termination of the
guarantee, and its producer responsibility.
For our products use pellets diameter 6 mm, length 30 mm and a maximum
of 6% and A1 certifi ed according to the UNI EN ISO 17225-2 standard. Keep the
pellets away from heat sources and not in humid environments or with explosive atmosphere.
