ATTENTION:
Failure to comply with the above implies
personal responsibility and invalidates
the warranty.
ATTENTION:
- Type B open chamber boilers must
not be installed in places where com-
mercial, artisan or industrial activities take
place, which use products that may develop
volatile vapours or substances
(
e.g. acid va-
pours, 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 regula-
tions in force, configurations B
23
and B
53
: the
boilers must not be installed in bedrooms,
bathrooms or bedsits.
Th
ey must neither be
installed in rooms containing solid fuel heat
generators nor in rooms communicating with
said rooms.
-
Th
e installation rooms must be permanently
ventilated, in compliance with the local regu-
lations in force
(
at least
6
cm
2
for every kW
of installed heat input, except in the event of
any increases needed for electro-mechanical
vacuum cleaners or other devices that could
put the installation room under vacuum
)
.
- Installation of appliances in B
23
and B
53
con-
figuration is recommended in non-residential
premises and which are permanently ventilated.
Filling the condensate drain trap.
On first lighting of the boiler,
fl
ue gas may
come out the condensate drain; after a
few minutes’ operation check that this no longer
occurs.
Th
is means that the trap is filled with
condensate to the correct level preventing the
passage of combustion products.
Risk of material damage after using sprays and liquids
to search for leaks
Leak sprays and liquids clog the reference hole P.Ref
(Part. 5 Fig. 37) 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)
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
fl
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
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.
Th
ese boilers are used to heat water to below boiling
temperature in atmospheric pressure.
Th
ey must be connected to a central heating system
and domestic hot water circuit suited to their perfor-
mance and capacity.
