Checks during operation

• Turn the unit on as described in sec. 1.3.
• 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. 4.3.
• Ensure the seal of the fumebox and burner door.
• Make sure the burner works properly. This check must be made with the special instruments, following the manu-
facturer's instructions.
• Check correct programming of the parameters and carry out any required customisation (compensation curve, pow-

3.3 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 cleaning 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.
The boiler casing, control panel and aesthetic parts can be cleaned with a soft and damp cloth, if necessary
A
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.
