10.1 - Boiler gas and

hydraulic connections

ATTENTION !!! Before installing, wash the

heating system and, if necessary, the domestic hot

water system thoroughly in order to remove any

residues or impurities that could compromise proper

appliance operation.

To identify the position of the fittings, see figures 8-1 and 8-2.

Gas connection

The gas connection must be done at the corresponding

fitting with a rigid metal pipe. The gas counter flow rate must

be sufficient for simultaneous use of all the gas appliances

connected to it. Connect the gas to the appliance according to

the standards in force. The diameter of the gas pipe coming

out of the generator does not determine the choice of the

diameter of the pipe between the appliance and the counter;

the latter must be chosen based on its length and head loss.

ATTENTION !!! Remember to install a gas shut-

off valve right before the appliance in order to be able

to shut off the gas supply.

ATTENTION !!! Supplying the boiler with

a different type of gas than those provided for is

prohibited.

10.2 - Boiler safety valve

(installer’s responsibility)

The appliance is supplied without an overpressure safety

valve to all the installer to choose the appropriate valve for

the system service pressure (check appliance operation

pressure in the technical features). Installation must be

done so as to allow the user to check valve intervention,

should it open. The safety valve drain (the installer’s

responsibility) must then be directed in order to avoid

danger for people in the event it intervenes.

ATTENTION !!! If the safety valve is not directed,

it could harm persons, animals or objects should it

intervene.
