Service And Maintenance - Ferroli Atlas D 30 KI 130 Instructions For Use Manual

4. SERVICE AND MAINTENANCE

All adjustment, conversion, commissioning and maintenance operations described be-
low must only be carried out by Qualified Personnel (meeting the professional technical
requirements prescribed by current regulations) such as those of the Local After-Sales
Technical Service.
FERROLI declines any liability for damage and/or injury caused by unqualified and un-
authorised persons tampering with the unit.
4.1 Adjustments
TEST mode activation
Press the heating buttons (details 3 and 4 -
tivate the fig. 1TEST mode. The boiler lights at maximum power.
The heating symbol (detail 24 - fig. 1) and DHW symbol (detail 12 - fig. 1) flash on the
display.
fig. 17 - TEST mode
To deactivate the TEST mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.
Burner adjustment
Boiler efficiency and correct operation depend above all on accurate burner adjustments.
Carefully follow the Manufacturer's instructions. The two-stage burners must have the
first stage adjusted to a power level not below the boiler's rated min. power. The power
of the second stage must not be higher than the boiler's rated max. power.
4.2 Start-up
B
Checks to be made at first lighting, and after all maintenance operations that
involved disconnecting from the systems or an intervention on safety devices
or parts of the boiler:
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the seal of the fuel system.
• Check correct prefilling of the expansion tank.
• Fill the water system and make sure that all air contained in the boiler and the sys-
tem has been vented, by opening the air valve on the boiler and any air valves on
the system.
• Make sure there are no water leaks in the system, domestic hot water circuits, con-
nections or boiler.
• Check correct connection of the electrical system and efficiency of the earthing sys-
tem
• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
Checks during operation
• Turn the unit on as described in sec. 2.3.
• Check the seal of the fuel circuit and water systems.
• Check the efficiency of the flue and air-fume ducts during boiler operation.
• Make sure the water is circulating properly between the boiler and systems.
• Check correct boiler lighting by performing various tests, turning it on and off with
the room thermostat or remote control.
• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on sec. 5.3.
• Ensure the seal of the fumebox and burner door.
• Make sure the burner works properly. This check must be made with the special in-
struments, following the manufacturer's instructions.
• Check correct programming of the parameters and carry out any required customi-
sation (compensation curve, power, temperatures, etc.).
4.3 Maintenance
Periodical check
To ensure correct operation of the unit over time, have qualified personnel carry out a
yearly check, providing for the following:
• The control and safety devices must function correctly.
• The fume exhaust circuit must be perfectly efficient.
• Check there are no obstructions or dents in the fuel supply and return pipes.
• Clean the filter of the fuel suction line.
• Measure the correct fuel consumption
• Clean the combustion head in the fuel outlet zone, on the swirl disc.
• Leave the burner running at full rate for approximately ten minutes, then analyse
the combustion, checking:
- All the elements specified in this manual are set correctly
- Temperatures of the fumes at the flue
- CO2 percentage content
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. For possible clean-
ing do not use chemical products or wire brushes.
• The gas and water systems must be airtight.
• The water pressure in the cold water system must be approx. 1 bar; otherwise, bring
it to that value.
• The circulating pump must not be blocked.

• The expansion tank must be filled.
• Check the magnesium anode and replace it if necessary.
A
The boiler casing, control panel and aesthetic parts can be cleaned with a soft
and damp cloth, if necessary soaked in soapy water. Do not use any abrasive
detergents and solvents.
Boiler cleaning
1. Disconnect the power supply to the boiler.
2. Remove the front top and bottom panel.
3. Open the door by undoing the knobs.
4. Clean the inside of the boiler and the entire path of exhaust fumes, using a tube
brush or compressed air.
5. Then close the door, securing it with the knob.
To clean the burner, refer to the Manufacturer's instructions.
4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 1) indicating the fault
code.
Some faults cause permanent shutdown (marked with the letter "A"): to restore opera-
tion, press the RESET button (detail 8 - fig. 1) for 1 second or RESET on the optional
remote timer control if installed; if the boiler fails to restart, it is necessary to eliminate the
fault indicated by the operation LED's.
other faults (indicated with the letter "F") cause temporary shutdowns which are automat-
ically reset as soon as the value returns within the boiler's normal operation range.
