The connection of ':+3 must be done using insulated air ducts of a nominal diameter of 160mm. The piping
can be connected either on the intake side, the blowing side or both.

2.5 - Plumbing connections
• It is mandatory to install a QHZ pressure-relief valve (not included) set to 7 bars on the domestic cold water
supply of the device. Membrane type valve are recommended.
This pressure-relief valve must conform to the domestic standard.
• The pressure-relief valve must be installed as close as possible to the cold water inlet of the device and WKH
SDVVDJHRIZDWHUPXVWQHYHUEHKLQGHUHG by any accessory (valve, pressure controller, etc...)
• The drain outlet of the pressure-relief valve must be sized following the requirements of construction
standard and must never be blocked. It must be connected by use of a funnel, allowing a minimum
20mm open space, to a vertical draining pipe of a diameter equal to the piping connection of the device.
• The drain outlet of the pressure-relief valve must be installed in a frost-free place and pointing downward.
• If the pressure of the domestic cold water supply is higher than 5 bars, install a pressure reducer above the
pressure-relief valve at the beginning of the installation (a pressure of 4 to 5 bars is recommended).
• It is advised to install a shut-off valve above the pressure-relief valve.
• In cases of installations equipped with
- piping of a small diameter
- ceramic plate valves
it is necessary to install, as close as possible to the shut-off valves, a domestic expansion vessel adapted to
the installation.
• For the do m estic hot water circuit, use the following m aterials:
- copper
- galvanised steel
- brass
Depending on m aterials used in the hot water circuit, inco m patibilities could result in da m age due
to corrosion.
