1.31 SYSTEM FILLING

Once the appliance is connected, proceed with system filling via the filling cock (Part. 26 Fig. 40).
Filling is performed at low speed to ensure release of air bubbles in the water via the appliance and central heating system vents.
The appliance has a built-in automatic vent valve on the pump.
Then open the radiator vent valves.
Close radiator vent valves when only water escapes from them.
The filling cock must be closed when the appliance pressure gauge indicates approximately 1.2 bar cold.
During these operations, enable the automatic vent functions on the appliance (Parag. 3.14);

1.32 FILLING THE CONDENSATE DRAIN TRAP

When the appliance is switched on for the first time, combustion products come out of the con-
densate drain. After a few minutes of operation, check that combustion flue gases are no longer
coming out of the condensate drain; this means that the drain trap has filled to a correct con-
densate height that the flue gases cannot pass through.

1.33 GAS SYSTEM START-UP

To start up the system, refer to the technical standards in force.
This divides the systems and, therefore, the commissioning operations, into three categories: new systems, modified systems, reactivated
systems.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or naked flames;
- bleed all air from pipelines;
- ensure the internal system is properly sealed according to the specifications set forth by technical regulations in force.
