General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP

Place of installation
The combustion circuit is sealed with respect to the place of installation! \room, therefore the unit can be installed in any room. However, the place of installation must be adequately ventilated to prevent the creation of dange rous conditions in case of even small gas leaks. This safety regulation is laid down by EEC Directive no. 2009/142 for all gas units, including those with sealed chamber. The unit is designed to operate in a partially protected place according to EN 297/A6, with minimum temperature of -5°C. The boiler must be installed in a sheltered place, e.g. under the slope of a roof, inside a balcony or in a protected recess. The place of installation must be free of flammable materials, objects and dusts or corrosive gases.

The boiler is arranged for wall mounting and comes as standard with a hooking bracket. Wall fixing must ensure stable and effective support for the generator.
If the unit is enclosed in a cabinet or mounted alongside, there must be sufficient space for removing the casing and for normal maintenance activities

Plumbing connections

Important
BThe 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.
Before installation, flush all the pipes of the system thoroughly to remove any residuals or impurities that could affect proper operation of the unit. In case of replacement of generators in existing installations, the system must be completely emptied and cleaned of any sludge and pollutants. For that purpose only use suitable guaranteed products for heating systems (see next section), that do not harm metals, plastics or rubber. The manufacturer declines any liability for damage caused to the generator by failure to properly
clean the system Carry out the relevant connections according to the diagram in fig. 12 and the symbols given on the unit

  • 1 = System delivery – Ø 3/4”
  • 3 = Gas inlet – Ø 1/2”
  • 5 = System return – Ø 3/4”

Antifreeze system, antifreeze fluids, additives and inhibitors
When necessary, antifreeze fluids, additives and inhibitors can be used only if the manufacturer of such fluids or additives guarantees that they are suitable and do not cause damage to the exchanger or other components and/or materials of the boiler and system. Do not use generic antifreeze fluids, additives or inhibitors that are not specific for use in heating systems and compatible with the materials of the boiler and system.

Water system characteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO3), use suitably treated water in order to avoid possible scaling in the boiler. Connection to a storage tank for domestic hot water production The unit’s electronic board is arranged for managing an external storage tank for domestic hot water production. Carry out the plumbing connections according to the diagram of fig. 13. Carry out the electrical connections as shown on the wiring diagram in fig. 29.
