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
PRESCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.

2.2 Place of installation

B
The combustion circuit is sealed with respect to the place of installation and
therefore the unit can be installed in any room except in a garage. The place
of installation must be sufficiently ventilated to prevent the creation of dan-
gerous conditions in case of even small gas leaks. Otherwise there may be
a risk of suffocation and intoxication or explosion and fire. This safety pre-
caution is required by EEC Directive No. 2009/142 for all gas units, including
so-called sealed chamber units.
The unit is designed to operate in a partially protected place, with a minimum temperature of -5°C. If provided with the
special antifreeze kit, it can be used with a minimum temperature down to -15°C. The boiler must be installed in a shel-
tered place, for instance 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
A
and for normal maintenance activities

2.3 Plumbing connections

Important
The safety valve outlet must be connected to a funnel or collection pipe to prevent
B
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 manufac-
turer cannot be held liable.
Before installation, flush all the pipes of the system thoroughly to remove any resi-
B
duals 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.
Make the connections to the respective points (see fig. 39, fig. 40 and fig. 41) and to the symbols given on the unit.
