5.4 Water connection
Connection of the stove to the hydraulic system must be exclusively performed by qualified
personnel, who is able to perfectly perform the installation, complying with the regulations in force
in the Country of installation.
If the installation of the stove requires interaction with another pre-existing system equipped with another
heating device (gas boiler, methane boiler, gasoline boiler, etc.), contacting qualified personnel able to
respond to the conformity of the system, according to the requirements of the law in force regarding the
subject, is more recommended.
The company denies any liability in case of damages to property or persons or in case of no or
incorrect operation if the aforementioned warnings are not complied with.
Caution:
To connect the delivery pipe, return pipe, refilling pipe and drains arrange flexible hoses at least 70
cm long and shut-off shutters in order to isolate the machine from the water system should moving it to perform
routine/special maintenance be required
.
Connect the thermal safety drain of the machine to an appropriate drain funnel with no shut-off valves.
In case of thermal safety drain valve operation, the water must be free to flow without causing damage to
persons and built-up area.
When the instrument is fully operational it produces hot water at a temperature necessarily lower than the
boiling one and therefore the thermal system must be designed in compatibility with the machine
specifications.
During installation and operation take into account that disposal of the minimum power delivered by the
machine must be ensured.
Make sure that the thermal hydraulic system is fitted with an additional and adequate closed
appropriately dimensioned expansion vessel.
For the installation of an additional expansion vessel take into account that usually 1 litre of vase compensated
10 litres of system and at least 1 litre is always dedicated to the water inside the boiler. The expansion vessel
inserted inside the device is pre-charge at the pressure indicated in the plate, adjust the pre-charged pressure
of the expansion vessels to the operating pressure of the thermal system.
We recommend installing a 1” anti-condensation valve with 55 °C opening and softener systems.
It is best to keep in mind that deposit drastically lower performance due to their extremely low thermal
conductivity.
5.4.1 System filling
Before performing the boiler connections thoroughly wash the thermal system
(pipes, heating bodies,
etc.) with appropriate paint or deposit removers able to remove any residues which may compromise the
correct operation of the boiler.
Hydraulic connections must be performed rationally using the connections of the boiler. The boiler safety
valve drain must be connected to a drain funnel. Otherwise, if the drain valve operates flooding the room, the
boiler manufacturer shall not be deemed responsible.
We recommend filling the system at a pressure of 1.0 - 1.2 bar (pressure is shown with the b symbol on the
boiler display) the boiler can still function from 0.6 bar to 2.5 bar.
In case of installation in spaces where temperature may drop below 0°C, inserting appropriate antifreeze in
the system is required since the boiler does not have an automatic antifreeze system
.
Thermostoves with domestic hot water production
If the water hardness of your home is high,
we recommend installing a softening system and a filter
upstream.
We recommend having the exchanger undergo yearly maintenance to remove limestone sediments and
mineral salts.
