COMPLIANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANU-
AL, THE PROVISIONS OF CURRENT LAW, THE NATIONAL AND LOCAL REGULA-
TIONS, AND THE RULES OF PROPER WORKMANSHIP.

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 dangerous conditions in case of even small gas leaks. Otherwise there
may be risk of suffocation and intoxication or explosion and fire. This
safety precaution is required by EEC Directive No. 2009/142 for all gas
units, including so-called sealed chamber units.

The unit is suitable for operation in a partially protected place in conformity with EN 297
pr A6, with minimum temperature -5°C (-15°C with optional antifreeze kit). It is advisable
to install the water heater under the slope of a roof, inside a balcony or in a sheltered
recess.
The place of installation must be free of dusts, flammable materials or objects, or corro-
sive gases.
The unit is arranged for wall mounting. Fix it to the wall according to the measurements
given on the cover drawing.

If the unit is enclosed in a cabinet or mounted alongside, there must be suffi-
cient space for removing the casing and for normal maintenance activities
