You must not use the boiler empty or only partly filled with
water.
THE USE OF EMPTY OR PARTLY FILLED BOILER MAY
LEADS TO EXPLOSION.
The domestic cold water supply pipe of the DHW
processing
circuit
remains
permanently open (the
closing of the net is made only by the valves from the
discharge points) to allow the dilatation taking over from
this circuit.
MOUNTING-INSTALLATION INSTRUCTIONS
The gas supply
The gas supply (NG or LPG) must be done in accordance with the standards.
*
The minimum/maximum inlet pressure in the gas valve, in case of using the natural gas
must be between 25-30mbar static and between 20-25 mbar dynamic.
*
The minimum/maximum inlet pressure in the gas valve, in case of using LPG, must be
between 30-50 mbar static and 25-45 mbar dynamic.
In case of not subsuming to these standards the combustion performances will lower.
On installing you must know the gas type that the boiler has been set for, to reset it correctly for
another gas type if it needs.
For exchanging the NG running for the LPG running you must follow two operations:
*
The setting from the electronic board which is performed by positioning the J6 jumper
(see the Electrical Diagram) on the two pines LPG module. (The J6 jumper is situated on a
single pine methane gas module).
*
The mounting of the nozzles set of 0,77 mm diameter used for LPG running. (The
diameter of these nozzles is 1,3 mm for methane gas).
The exchanging for NG is realized by performing the setting operations, from above, in the
reverse sense.
The setting will be performed by the producer following the beneficiary request or the service
authorized according to the current standards, operation which is performed on putting into service.
!
You must install a pressure controller on the gas supply
circuit.
!
The gas supply pipes must not have diameters smaller than
the boiler coupling.
Electric power supply
The boiler must be connected to a monophase net of 230 V-50 Hz with zero protection,
through the 5A fusible plugs. The colours semantics will be as follow: brown= phase, blue=null,
green-yellow= earthing.
The external connections must be according to the current standards. The connection to the
electrical network of the building must allow a complete electrical isolation of the boiler in case an
intervention must be done.
