8.6.1 Standard aeraulic connections

In addition to the spaces indicated in section 8.4, the heat
pump requires adequate air ventilation.
• Create a dedicated air duct as indicated in fig. 52.
The simultaneous operation of
an open chamber fireplace (e.g.
open fireplace) and of the heat

pump causes a dangerous nega­
tive pressure in the environment.

Install each air duct making sure that:
• It does not weigh down on the equipment.
• It allows maintenance operations.
• It is adequately protected to prevent the accidental intrusion
of materials inside the equipment.
• The connection to the outside must be done with suitable,
non-flammable piping.
• The total equivalent length of the extraction pipes plus the
delivery, including grilles, must not exceed 12 m.

• While operating, the heat pump tends to lower the tempera-
ture of the room if the air is not ducted outside.
• A suitable protection grille must be fitted during installation
near the external air exhaust pipe, to prevent foreign bodies
from getting inside the device. To ensure maximum product
performance, the grille must be selected from those with low
pressure loss.
• To prevent the formation of condensate: isolate the air ex-
haust pipes and the ducted air cover attachments with a va-
pour proof thermal coating of a suitable thickness.
• If necessary, install mufflers to prevent noise due to the air
flow. Fit the pipes, wall entries and connectors to the heat
pump systems with vibration damping.
