2.2 Siting of appliance.
The appliance's combustion chamber is sealed from the surrounding environment and as a result the
appliance may be installed in any room without purpose built ventilation. The installation environment
must nonetheless feature sufficient ventilation, to avoid dangerous conditions arising in the event of
even minor gas leaks. These safety standards are imposed by EEC Directive no. 09/396 for all gas appli-
ances, including the so-called sealed appliances.
The place of installation must in any case be free of dust, inflammable objects or materials and corrosive
gases. The environment must be dry and not prone to freezing.
The boiler is supplied ready for wall-hung installation. The rear frame of the appliance has a series of
slots for fastening it to the wall, using screws with wall plugs. The fastening to the wall must provide
stable and effective support of the appliance.
The boiler must be fastened to a closed part of wall, which is free of apertures or holes behind the frame
of the boiler that may allow the internal components of the boiler to be reached.
If the appliance is enclosed in a cabinet or alongside another appliance, minimum clearances must be
adhered to. Fig. 2 and Tab. 3 show the minimum and recommended space to be left free around the
appliance.
