Directions for use
If the installation of the thermostove provides
interaction with another existing system complete
with a heater (gas thermostove, gas thermostove,
oil thermostove, etc..) consult qualifi ed personnel
who can then answer the compliance of the system,
as envisaged by the law in force.
Flushing the system
In accordance with the UNI-CTI 8065 is strongly
recommended to wash the entire system
before connecting it in order to get rid of
residues and deposits.
After fl ushing the system to protect it against
corrosion and deposits, it is recommended the
use of inhibitors. Upstream from the thermostove,
always install shutters so as to disconnect it from
the plumbing system should it be necessary to
move it, or when it requires routine and/or special
maintenance. Connect the thermostove using hoses
so that the thermostove is not too strictly connected
to the system, and to allow slight movement.
These are as helpful as the supply and return piping
system if the heating system is on a higher fl oor
than the thermostove.
The exhaust pipe pressure is connected temporarily
to a carafe or a funnel to avoid, in case of
overpressure, that the water gush bathrooms and
the structure and the fl oor.
Replenishment of the System
The replenishment has to be slowly carried out in
order to let the air bubbles fl ow out through the
right oulets that are placed on the heating system.
In heating systems with a closed circuit the loading
cold pressure of the system and the infl ation
pressure of the expanding vase must correspond.
• in heating systems with open vase, the direct
contact between the circulating liquid and the air is
allowed. During the heating-season the user must
regularly check the circulating water level in the
expansion vase. The content of water in the system
of recirculation must be stable hold.
Experiences show that the user must regularly check
the water level every 14 days in order to maintain a
stable water content.
The replenishment process must be carried out
in case of necessity of more water when the
thermostove has cooled down.
These preventive measures aim to prevent the
insurgence of thermic stress of the steel body of the
thermostove.
• in systems with open vase, the pressure of water
in thermostove, when the system is cold, mustn't
be lower than 0,3 bar;
• the water used to fi ll up the heating system must
be decontaminate and without air.
When all the hydraulic connections are done,
proceed to test the pressure of the seals, through
the fi lling of the heating thermostove.
VENTING
SAFETY
VALVE
You must not mix water of the
heating system with antifreeze or
anticorrosion substances in wrong
concentrations. This could ruin the
seals and provoke the insurgence of noises
while operating.
