Do not install the heater horizontally with the wall supports
horizontal or over the oor.
1.4. Water system installation
WARNING TO THE INSTALLER: the insulating sockets provided
with the heater must be placed on the entrance and exit pipes to
eliminate the risk of galvanic pairs as teon is used in the thread
of the pipes.
A- The heater MUST be installed with the security tting that comes
with it. No water system accessory may be placed between the
security tting and the cold water pipe (stop cock, anti-return, etc).
The security tting drainage outlet MUST be connected to a
water drainage pipe that has to have a diameter that is at least
equal to the diameter of the pipe connected to the boiler, with
a continuous inclination, open to the atmosphere and with a
minimum distance of 20 mm. During the warm-up time the water
expands producing a drip (approximately 3% of its capacity during
each heating cycle). This is not a cause for concern because it
is a normal phenomenon. Please ensure that the water drainage
conduct pipe is protected from frost. To drain the heater, lift the
handle of the security tting. It is also necessary for this handle to
be periodically checked to avoid blockage by, for example: mud
deposits, limescale deposits, etc.
B- When the pressure of the network is higher than 5 bars, it is
necessary to install a pressure reducer as near as possible to
the meter.
