2.3 Plumbing connections
The heating capacity of the unit must be previously established by calculating the building's heat requirement according
to current regulations. The system must be provided with all the components for correct and regular operation. It is ad-
visable to install on-off valves between the boiler and heating system allowing the boiler to be isolated from the system
if necessary.
B
The safety valve outlet must be connected to a funnel or collection pipe, to prevent water spurting onto the
floor in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and floods the
room, the boiler manufacturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that could affect prop-
er operation of the unit.
B
A filter must also be installed on the system return piping to prevent impurities or sludge from the system clog-
ging and damaging the heat generators.
The filter must be installed when replacing the generators in existing systems. The manufacturer declines any
liability for damage to the generator caused by failure to install or inadequate installation of this filter.
Carry out the relevant connections according to the diagram in sec. 4.1 and the symbols given on the unit.
The connection kits given in fig. 6 are supplied standard.

System water charcteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO
3
), the use of suitably treated water is advisable in order
to avoid possible scaling in the boiler. The treatment must not in any case reduce the hardness to values below 15°F
(Decree 236/88 for uses of water intended for human consumption). Water treatment is indispensable in the case of
very large systems or with frequent replenishing of water in the system. If partial or total emptying of the system be-
comes necessary in these cases, it is advisable to refill it with treated water.
