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 flue
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 similar, choose a
separate installation area that ensures combustion air supply that is free from chemical substances.
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 after using sprays and liquids to search for leaks
Leak sprays and liquids clog the reference hole P.Ref. (Fig. 55) 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).
Filling the condensate drain trap
On first lighting of the boiler, flue gas may come out the condensate drain; after a few minutes’
operation check that this no longer occurs. If this is the case, the drain trap is correctly filled
with condensate up to a height that does not allow the flue gas to pass.
Type B open chamber boilers must not be installed in places where commercial, artisan or in-
dustrial activities take place, which use products that may develop volatile vapours or sub-
stances (e.g. acid vapours, glues, paints, solvents, combustibles, etc.), as well as dusts (e.g. dust
deriving from the working of wood, coal fines, cement, etc.), which may be damaging for the
components of the appliance and jeopardise functioning.
Unless otherwise provided for by local regulations in force, in configurations B
23
and B
53
, the
boilers must not be installed in bedrooms, bathrooms or bedsits. Moreover, they must not be
installed in places where solid fuel heat generators are present and in adjoining rooms.
The installation rooms must be permanently ventilated, in compliance with the local regula-
tions in force (at least 6 cm² for every kW of installed heat input, except in the event of any in-
creases needed for electro-mechanical vacuum cleaners or other devices that could put the in-
stallation room under vacuum).
Install the appliances in B
23
and B
53
configuration in non-residential premises and which are permanently ventilated.
