2. Installation
2.1 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 PRE-
SCRIPTIONS OF NATIONAL STANDARDS AND LOCAL REGULATIONS AND THE RULES OF PROPER WORK-
MANSHIP
2.2 Place of installation
The combustion circuit is sealed with respect to the place of installation, therefore the unit can be installed in any room.
However, the place of installation must be sufficiently ventilated to prevent the creation of any dangerous conditions in
case of even small gas leaks. This safety precaution is required by EEC Directive no. 90/396 for all gas units, including
those with a so-called sealed chamber.
Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. The room
must be dry and not subject to freezing.
The boiler is arranged for wall mounting and comes standard with a hooking bracket. The wall fixing must ensure stable
and effective support for the generator.
A
If the unit is enclosed in a cabinet or mounted alongside, a space must be provided for removing the casing
and for normal maintenance operations
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 drain valve is activated 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 residuals or impurities that could affect correct
operation of the unit.
B
A filter must be installed on the system return piping to prevent impurities or sludge from the system clogging
and damaging the heat generators.
The filter MUST be installed when replacing generators in existing systems. The manufacturer declines any
liability for damage caused to the generator due to failure to install or inadequate installation of this filter.
Make the relevant connections according to the diagram in sec. 4.1 and the symbols given on the unit.
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.
