2.2.d. STAB models on base structures
This appliance is fitted with a base structure which
is fixed to the product while it is still at the company.
Position the appliance on a perfectly flat and level
surface.

3. Water connection
1. The operating pressure is indicated on the data
plate of the water heater (see water heater).
2. The water heater must be fitted with a safety
assembly which conforms to current national
legislation, connected to the cold water pipe. We
recommend the use of diaphragm assemblies.
The safety assembly must be fitted as
close as possible to the cold water inlet
of the water heater and THE PASSAGE
OF WATER MUST NEVER BE
PREVENTED by any type of accessory.
If, for technical reasons, the safety
assembly cannot be installed with a
direct connection to the cold water inlet,
(max 50 cm) the installed connection
must be rigid and must always be made
using material which is able to withstand
pressures of at least 7 bar and high
temperatures.
The drainage outlet of the safety
assembly must never be obstructed and
must be connected to a vertical drainage
pipe with a diameter which is at least
equal to that of the appliance connection
piping, with a funnel which creates an
empty space of at least 20 mm leading
outwards. This piping must be installed
in a room which is not subject to icy
conditions, sloping downwards.
3. The connection of a water heater to copper
piping must be performed using a dielectric
connection. These dielectric connections are
available as an optional extra or as standard,
depending on the model purchased.
If you only have one dielectric connector, you must
fit it to the hot water outlet!
4. When the input pressure of the network is
greater than 4.5 bar, a pressure reducer must be
installed upstream of the safety assembly.
5. If the water systems have the following
features:
➢ small pipes;
➢ taps with ceramic plates / mixer taps;
a “ram stabilising” device or a domestic hot water
expansion vessel suited to the system must be
installed as close as possible to the taps.
6. To prevent burns from occurring, use suitable
mixers which ensure that the temperature does not
exceed 50ºC at the drawing points (this is a legal
obligation in France).
We recommend that a shut-off valve
is installed upstream from the safety
assembly.
See pictures 6, 7, 8, 9, 10, and 12.
