Fit the pipes, the wall through holes and the
connections to the heat pump with vibration
damping systems.
WARNING!
The simultaneous operation of an open-flue
firebox (e.g. an open-flue fireplace) together
with the heat pump causes a dangerous
environmental pressure drop. This could cause
the backflow of exhaust gas into the
environment itself.
Do not operate the heat pump together with
an open-flue firebox.
Use only sealed-chamber fireboxes (approved)
with a separate duct for combustion air.
Keep the doors to the boiler room closed and
hermetically sealed if it does not have a
combustion air supply in common with
inhabited areas.
Installation and user manual
6.2.1 Particular installation
conditions
One of the peculiarities of the heat pump heating
system is represented by the fact that these units cause
a considerable reduction of the air temperature that is
generally ejected from inside the home. Apart from
being colder than the ambient air, the exhaust air is also
completely dehumidified; for this reason, it is possible to
allow the air to flow back into the home in order to cool
specific environments or rooms during the summer.
Installation consists of the splitting of the discharge pipe
to which two shutters are applied ("A" and "B") with the
aim of directing the air flow either towards the inside
(Fig. 5a) or the outside of the home (Fig. 5b).
