3. INSTALLATION
3.1 General Instructions
THE WATER HEATER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN
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.
3.2 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 dangerous conditions in case of even small gas
leaks. This safety standard is required by EEC Directive no. 90/396 for all gas units, in-
cluding those with sealed chamber.
The unit is suitable for operation in a partially protected place in conformity with EN 297
pr A6, with minimum temperature of -5°C (-15°C with optional antifreeze kit). It is advis-
able to install the water heater under the slope of a roof, inside a balcony or in a sheltered
recess .
The place of installation must in any case be free of dust, flammable materials or objects
or corrosive gases.
The unit is arranged for wall mounting. Fix it to the wall according to the measurements
given on the cover drawing .
A
If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
vided for removing the casing and for normal maintenance operations
