Figure 4.2 – Clearances
Position the appliance preferably out of range of rooms and/or environments where strict
silence is required, such as bedrooms, meeting rooms, etc.
Evaluate the acoustic impact of the appliance on the basis of the installation site: avoid
locating the appliance in positions (corners of buildings, etc.) that could amplify the noise
it produces (reverb eect).
4.3 HYDRAULIC CONNECTIONS
General indications
The hydraulic plant may be created using pipes in stainless steel, black steel, cop-•
per or crosslinked polyethylene for heating/cooling plants. All water pipes and pipe
connections must be adequately insulated in accordance with current regulations,
to prevent heat loss and the formation of condensate..
To prevent icing in the primary circuit in the winter, the appliance is equipped with •
an antifreeze device that activates the external water circulation pump of the pri-
mary circuit (if controlled by the appliance) and the burner of the appliance itself
(when necessary). It is therefore necessary to ensure a continuous supply of elec-
tricity and gas to the appliance throughout the whole of the winter period. If it is
not possible to ensure a continuous supply of electricity and gas to the appliance,
use glycol antifreeze of the inhibited monoethylene type.
If glycol antifreeze is to be used (see Paragraph 4.6 FILLING OF HYDRAULIC CIR-•
CUIT → 34), DO NOT USE galvanised pipes, as they are potentially subject to corro-
sion phenomena in the presence of glycol.
When rigid pipes are used, to prevent the transmission of vibrations, it is recom-•
mended that the appliance water inlet and outlet are connected with antivibration
joints.
