The filling pressure during cold status should be 1 bar.
If during operation the system pressure drops (due to evaporation of the gas dissolved in water) to values less than the
minimum indicated above, the User shall, acting on the valve from the load back to the initial value.
For optimal operation of the stove in operation (hot), the boiler pressure must be 1.5 bar. Do not exceed 2 bar. At the end of
the operation always close the filling tap.
3.3.3 WATER CHARACTERISTICS
The characteristics of the water for filling the plant, are very important to avoid the deposition of minerals and the creation of
deposits along the piping within the boiler and heat exchangers. Therefore, it is advised to check with your plumber / fitter the
following characteristics:
● Hardness of water circulating in the system to remedy any problems and limestone deposits especially in the hot water
heat exchanger. (> 25° French)
● Installing a water softener (if the water hardness is > 25° French)
● Fill the system with treated water (demineralized)
● Any set of a circuit condensation.
● Installation of hydraulic shock absorbers to avoid the phenomenon of "water hammer" along the fittings and pipes.
For those with very large systems (with large water content) or who require frequent replenishment of the plants in
the plant to install water softeners, especially because the scale significantly reduce the thermal conductivity!
3.3.4 KIT WATER PRODUCTION
All thermo stoves are equipped with HANKS kit for the production of hot water characterized by:
● Plate heat exchanger
● 3-way diverter valve, electric motor-driven
● Electrical Flow meter
● Stainless steel finned pipes and fittings for connecting
● Pressure valve
The kit has the task of heating hot water from the water line of the house. At a time when there is hot water demand by opening a tap,
the internal flow-meter commands the diverter valve to convey the hot water contained inside the boiler, to the plate heat exchanger.
The hot water temperature will dependent on the water temperature inside the heater, with approximation, is calculated by removing
10° -15° C to the value read on the control panel of the heater (boiler water temperature). For proper lifetime operation of the heat
exchanger plates , it is necessary to know the hardness of your water to prevent fouling, and to block the exchange.
3.5. EXAMPLE OF INSTALLATION DIAGRAMS
The diagrams below are merely indicative. For a proper connection, always follow the notes of the plumbing and heating installer with
proven experience. The hydraulic system must meet the mandatory regulations of the place, region or state. The installation, testing and
certification of operation must be performed only by authorized personnel, with the issue of certification that the work has been completed
in a "state of art" performance, attesting the conformity of the work in compliance with laws and regulations. The manufacturer disclaims
any responsibility in case of non-compliance to the above, especially in the absence of proof of certification work in a "STATE OF ART"
execution .
