INSTALLERUSERMAINTENANCE TECHNICIANTECHNICAL DATA
Check the environmental operating conditions of all parts relevant to installation, referring to the values shown in the techni-
cal data table in this booklet.
Installation of the appliance when powered by LPG or propane air must comply with the rules
regarding gases with a greater density than air (remember, as an example, that it is prohibited
to install plants powered with the above-mentioned gas in rooms where the oor is at a lower
quota than the country level).
If installing a kit or servicing the appliance, always empty the system’s domestic hot water circuit rst so as not to compromise
the appliance’s electrical safety (Parag. 2.12, 2.13).
Always disconnect the appliance from voltage and, depending on the type of operation, decrease the pressure and/or bring it to
zero in the gas and DHW circuits.
If the appliance is connected to a low temperature direct zone, it is necessary to check the necessary ow rate and possibly add a
relaunch pump.
It is just as important that the intake grids and exhaust terminals are not obstructed.
Check that no ue 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 ue gas.
e minimum distance for exhaust pipes from ammable materials must be at least 25 cm.
Keep all ammable objects away from the appliance (paper, rags, plastic, polystyrene, etc.).
Do not place household appliances underneath the appliance as they could be damaged if the safety valve intervenes, if the
drain trap is blocked, or if there are leaks from the hydraulic connections; otherwise, the manufacturer cannot be held respon-
sible for any damage caused to the household appliances.
For the aforementioned reasons, we recommend not placing furnishings, furniture, etc. under the appliance.
Any modication to the appliance that is not explicitly indicated in this section of the booklet is forbidden.
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, polystyrene 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 sucient space for routine servicing; for minimum installation
distances, see Fig. 3.
Installation standards
