ARENA 30 C
3.2 Commissioning and testing
The appliance must only be set-up for use by Qualified Personnel, such as personnel from Technical
organization.
Checks to be performed during the first ignition, and after all maintenance operations which may have
required the disconnection of the systems or intervention on the safety devices or parts of the boiler:
Before igniting the boiler:
• Open any shut-off valves between the boiler and the systems
• Check the seal of the gas system, proceeding with care and using a soapy water solution to find any leaks
from the connections.
• Fill the system as indicated earlier and ensure that the air contained in the boiler and the system has been
completely vented, by opening the air bleeding valve on the top of the appliance (Fig. 2) and any bleeding
valves in the system.
• Check that there are no water leaks in the heating system, in the domestic hot water circuits, in the
connections or in the boiler
• Check the correct connection of the electrical system
• Check that the appliance is properly earthed;.
• Check the correct connection of the appliance to the system for draining the condensation and the
functioning of the condensation drain system itself.
• Check that the pressure value and gas rate for the heating system are correct.
• Check that there are no flammable liquids or materials in the
immediate vicinity of the boiler
• Check that the non-return valve is operating (fig. A)
Igniting the boiler:
• Open the gas cock upstream from the boiler.
• Bleed the air in the pipe upstream from the gas valve.
• Close any switches or insert any plugs upstream of the boiler
• Place the main switch in the ON position.
• The boiler will switch on and perform a complete self-test cycle
lasting around one minute, to check the operation of the main parts. The display shows, in sequence:
• If the cycle is performed correctly:
- If domestic hot water or heating is not required, the display shows a small "o" (standby mode) followed
by the temperature value of the outlet sensor. Then use the room thermostat or remote control to
activate the request for heating
- If there is a request, the display will pass from the standby phase " o " to the heating phase " c " and
the boiler will automatically begin operation, controlled by its regulation and safety devices.
- If anomalies arise during the self-test cycle or the successive ignition phase, the display will show the
corresponding error code and the boiler will shut-down. Wait around 15 seconds and then press the
reset button. The boiler will repeat the ignition cycle. If, after a second attempt, the boiler does not start,
refer to the paragraph on "Troubleshooting" 3.5.
Note In the case of power failures while the boiler is in operation, the burner assembly will switch off. On
the return of mains power, the boiler will again perform the self-test cycle, following which the burner
assembly will automatically restart (if there is still a request for heat).
