Initial Start-Up - Ferroli DOMIcompact F 30 B Instructions For Use, Installation And Maintenance

DOMIcompact F 30 B
Adjusting the maximum heating output
To adjust the heating power, set the boiler on TEST operation (see par. 3.1). Turn the heating tem-
perature control knob (ref. 1 - Fig. 1) clockwise to increase the power or anticlockwise to decrease it
(see pressure/power diagram Fig. 21). The display shows the power setting from 0 to 99%. Exit TEST
operation (see par. 3.1). The maximum heating power will remain as set during the TEST mode. (100%
output shown as 99% due to the display only being 2 digits).
Ignition power adjustment
To adjust the ignition power, set the boiler on TEST operation (see par. 3.1).
Turn the hot water temperature control knob (ref. 3 - Fig. 1) clockwise to increase the power or anti-
clockwise to decrease it (see pressure/power diagram Fig. 21). The display shows the power setting
from 0 to 60%. Exit TEST operation (see par. 3.1). The ignition power will remain as set during the TEST
mode.
NOTE Recommended ignition pressure for standard 100mm concentric flueing is 30%.

3.2 Initial start-up

Commissioning must be performed by Qualified Personnel only!.
Checks to be made at initial start up, and after all maintenance operations that involved discon-
necting from the system or an intervention of a safety device.
Before lighting the boiler:
• Open any isolation valves between the boiler and the systems.
• Check the soundness of the gas system, proceeding with caution and using a suitable leak detection
fluid to detect any leaks in connections.
• Fill the water system and make sure that all air contained in the boiler and the system has been vented
by opening the air vent valve on the boiler and any vent valves on the system.
• Make sure there are no water leaks in the system, hot water circuits, connections or boiler.
• Make sure the electrical supply is properly connected.
• Make sure that the unit is connected to a good earthing system.
• Make sure that there is sufficient gas available to produce safe combustion. (min inlet working pressure
= 20mbar)
• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler.
Lighting the boiler
• Open the gas isolation valve on the boiler.
• Purge the air from the gas pipe work to the boiler.
• Switch on the electrical supply to the boiler.
• Turn knob "1" (Fig. 1) onto Winter in correspondence with a value greater than 50 °C and the room
thermostat knob, if applicable, onto the desired temperature setting. At this point, the burner will light
and the boiler begins to function automatically, controlled by its software and safety devices.
If, after correctly carrying out the lighting procedure, the burners do not light and fault F1 is
generated, press the RESET button for 1 second and release it. The software will repeat the
ignition cycle in the next 30 seconds. If the burners do not light after the second attempt, consult
the "Troubleshooting" paragraph.
In case of an electrical power failure while the boiler is working, the burners will go out and re-
ignite automatically when power is restored.
