500 mm below where the pipes exit the heater to allow access for
maintenance and repair and any necessary future maintenance
operations.
Do not install the heater horizontally with the wall supports
horizontal or over the floor.
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 teflon is used in the thread
of the pipes.
A-
The heater MUST be installed with the security fitting that comes
with it. No water system accessory may be placed between the
security fitting and the cold water pipe (stop cock, anti-return, etc).
The security fitting 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 fitting.
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.
