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 shut-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. If this is not done, and the drain valve trips and floods the room,
the boiler manufacturer is not to be held responsible.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully flush all the pipes of the system to remove residues or impurities that could impair the op-
eration of the unit.
B
In addition, a filter must be installed on the system return piping to prevent debris or sludge from the system
clogging and damaging the heat generators.
The filter MUST be installed when replacing generators in existing systems. The manufacturer shall not be
held liable for any damage caused to the generator by failure to install or inadequate installation of this filter.
Make the connections to the corresponding connections as shown on the drawing in sec. 4.1 and by the symbols on the
unit.
