INSTALLATION
5 Appliance location
• Before choosing a site for the appliance, carefully read the
safety warnings and installation manual.
• Ensure that wall to which the appliance will be mounted on is
structurally safe in order to support the weight of the appliance.
• Ensure there is sufficient space available for the appliance,
taking care that minimum clearances are adhered to ensure
that the connections to the water can be accessed and
inspected.
• The appliance must be installed in a room protected from
freezing. Take all necessary precautions.
• Explain these requirements to the appliance user.

6.2 Recommendations before installing
6.2.1 Heating circuit design
The heat transmitters may be low temperature (under-floor
heating, low-temp radiator ...) and high temperature (cast iron
radiator ...).
The installation pipework should be calculated using a flow /
pressure curve. The distribution will be determined by the flow
corresponding to the power actually required, regardless of
the maximum power that can be provided by the installation’s
generators.
The pipework should be designed and installed in such a way
so as to make all provisions necessary to avoid air pockets and
facilitate the permanent degassing of the installation. Venting
valves must be placed at each high point of the tubes, as well as
on all radiators.
The total volume of water for the heating circuit depends,
among other factors, on the cold static load of the boiler’s
expansion tank. It is recommended that a drainage valve be
installed at the lowest point of the installation.
If using thermostatic valves, do not equip all radiators with
them, placing these valves at high demand sites and never at
the sites in which the room thermostats are installed.
- In both new and existing installations, the radiator circuit
must be flushed prior to installing the new appliance in
accordance with BS:7593.
- If a system component is not put in place immediately,
protect the different connections so that the plaster and paint
does not spoil water tightness for later connecting.
6.2.2 Heat pump circuit design
The pipework should be designed and installed in such a way
so as to make all provisions necessary to avoid air pockets and
facilitate the venting of air from the installation. Bleed valves are
to be installed at each of the pipes' highest points.
• In order to avoid the transmission of vibration to surrounding
structures, use hoses for water connections.
b Insulate the pipes with a UV- and high-
temperature-resistant insulation.
