DO NOT
USE, BOILER MAINTENANCE OUT OF SERVICE
3.10 - CENTRAL HEATING CONNECTION
WARNING!
Before installing the boiler we recommend
that the system is flushed out with a
suitable product in order to eliminate any
metallic tooling or welding residues, oil
and grime which could reach the boiler and
affect the
proper running of the boiler.
Do not use any solvents for flushing out
the system as they could damage the
system and/or its components.
Non-observance of these instructions
could cause injury to persons, animals or
damage to property.
The manufacturer shall not be held liable
for any such injury and/or damage.
Warning!
Be sure to make a connection pipes
without stress mechanics points to avoid
the danger of loss!
The flow and return circuits have to be connected to the boiler
via the respective connections as indicated on page 8.
When determining the size of the CH circuit pipes it is
essential to bear in mind the pressure losses induced by the
radiators, any eventual thermostatic radiator valves, lockshield
valves and by the system’s layout..
Ensure yourself that the system’s piping is
not used as earth clamps for the electrical
or telephonic system. They are absolutely
unsuitable for this use. In a short time this
could cause serious damage to the piping,
boiler and radiators.
Pressure relief valve drain pipe
In correspondence to the heating pressure relief valve
provision should be made to install a discharge pipe with a
funnel and a siphon which lead to an adequate drainage. The
drainage has to be controllable by sight.
WARNING!
If this precaution is not taken it could lead
to injury to persons, animals or damage to
property.
The manufacturer shall not be held liable
for any such injury and/or damage.
Expansion vessel connection
The INOXIA GJ boilers are suitable for operation with water
movement forced with open or closed expansion vessel
An expansion vessel is always necessary to compensate the
increase in water volume caused to the heating.
The piping connecting of the expansion vessel
will start by the attack T3 (see Table Size) and
should not have any interception valve
Connection the filling /discharge cock
For the filling and the discharge of the boiler an apposite cock
can be connected to the attack T5, which is located in back
.
