TECHNICAL DATA
ese boilers, unless properly isolated,
are not suitable for installation on walls
made of combustible material.
Installing the wall recessed frame kit must guarantee
the boiler stable, ecient support.
e recessed frame kit ensures appropriate support only if instal-
led correctly (according to the rules of good practice), following
the instructions on its instructions leaet.
e recessed frame for the boiler is not a supporting structure and
must not replace the wall removed. It is necessary to position the
boiler inside the wall.
For safety reasons against any leaks it is necessary to plaster the
boiler housing in the brick wall.
e installation of the boiler on the wall
must guarantee a stable and eective
support to the generator itself.
e plugs (standard supply) are only to be used to x the boiler to
the wall; they only ensure adequate support if inserted correctly
(according to technical standards) in walls made of solid or se-
mi-hollow brick or block. In the case of walls made from hollow
brick or block, partitions with limited static properties, or in any
case walls other than those indicated, a static test must be carried
out to ensure adequate support.
ese boilers are used to heat water to below boiling tem-
perature in atmospheric pressure.
ey must be connected to a central heating system and
domestic hot water circuit suited to their performance
and capacity.
Risk of damage due to corrosion caused by unsuitable
combustion air and environment.
Spray, solvents, chlorine-based detergents, paints, glue,
ammonium compounds, powders and similar cause
product and ue duct corrosion.
Check that combustion air power supply is free from
chlorine, sulphur, powders, etc.
Make sure that no chemical substances are stored in the
place of installation.
If you want to install the product in beauty salons, paint
workshops, carpenter’s shop, cleaning companies or si-
milar, choose a separate installation area that ensures
combustion air supply that is free from chemical sub-
stances.
Make sure the combustion air is not fed from chimneys
that were used with gas boilers or other heating devices.
In fact, these may cause an accumulation of soot in the
chimney.
Risk of material damage aer using sprays and liquids to search
for leaks
Leak sprays and liquids clog the reference hole P. Ref.
(Fig. 39) of the gas valve, damaging it irreparably.
During installation and maintenance, do not use spray
or liquids in the upper area of the gas valve (side referring
to the electric connections).
