2. Installation
2.1 General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN AC-
CORDANCE 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
The combustion circuit is sealed with respect to the place of installation and
B
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 sheltered place, for instance under the slope of a roof, in-
side a balcony or in a protected recess.
The place of installation must be free of flammable materials, objects and dusts or corrosive gas-
es.
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
A
for removing the casing 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. Other-
wise, 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 re-
B
siduals 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 respective connections, paying attention to the symbols provided on the unit.
Frost protection system, antifreeze liquids, additives and inhibitors
If necessary, the use of antifreeze liquids, additives and inhibitors is allowed, only and exclusively
if their manufacturer guarantees that the products are suitable for use and do not cause damage
to the boiler's heat exchanger.or other components and/or materials of the boiler and system. It is
prohibited to use generic antifreeze liquids, additives or inhibitors that are not expressly suitable
for use in heating systems and compatible with the materials of the boiler and system
