If installing a kit or servicing the appliance, always emp-
ty the system’s domestic hot water circuit first so as not to
compromise the appliance’s electrical safety (Parag. 2.9,
2.10).
Always disconnect the appliance from voltage and, de-
pending on the type of operation, decrease the pressure
and/or bring it to zero in the gas and DHW circuits.
If the boiler is connected to a low temperature direct
area, it is necessary to check the necessary flow rate and,
if necessary, add a booster pump.
Before installing the appliance, ensure that it is delivered
in perfect condition; if in doubt, contact the supplier
immediately.
Packing materials (staples, nails, plastic bags, polysty-
rene foam, etc.) constitute a hazard and must be kept out
of the reach of children.
If the appliance is installed inside or between cabinets,
ensure sufficient space for routine servicing; for mini-
mum installation distances, see Fig. 3.
It is just as important that the intake
grids and exhaust terminals are not ob-
structed.
Check that no flue gas recirculation is
found in the air sample points. Allow the
appliance to reach the maximum heat
output; theCO
2
value measured in the air
must be less than 10% of that measured
on the flue gas.
Keep all flammable objects away from the appliance (pa-
per, rags, plastic, polystyrene, etc.).
The minimum distance for exhaust pipes from flamma-
ble materials must be at least 25 cm.
Do not place household appliances underneath the boil-
er as they could be damaged if the safety valve inter-
venes, if the drain trap is blocked, or if there are leaks
from the hydraulic connections; otherwise, the manu-
facturer cannot be held responsible for any damage
caused to the household appliances.
For the aforementioned reasons, we recommend not
placing furnishings, furniture, etc. under the boiler.
In the event of malfunctions, faults or incorrect opera-
tion, turn the appliance off and contact an authorised
company (e.g. the Authorised Technical Assistance
Centre, which has specifically trained staff and original
spare parts).
Do not attempt to modify or repair the appliance alone.
Any modification to the appliance that is not explicitly
indicated in this section of the booklet is forbidden.
