Close the boiler isolation gas cock and turn off the electricity to the boiler.
Important
: If the boiler is not to be used for lengthy periods during the winter, to avoid frost damage,
you are recommended to drain the water from the circuits (domestic hot water and central heating).
Alternatively, drain the domestic hot water system only and add special anti-freeze to the central hea-
ting system.
Checks and controls after first start-up
• Check there are no leaks in the gas and water circuits.
• Check correct boiler start up by carrying out start up and shut down tests using the boiler stat.
• Check the integrity of the air-flue pipes during boiler operation.
• Check that the gas consumption indicated on the meter corresponds to that given in Technical Data.
• Check that water is circulating correctly. Balance the radiators to ensure that the flow and return diffe-
rential does not exceed 20°C.
• Check that when operating in the “Winter” mode, the pump stops and domestic hot water is produced
correctly when the hot water tap is turned on.
• Check that in the “Summer” mode, the burner lights up and shuts down correctly when the domestic
hot water tap is turned on and off.
• Check that the domestic hot water flow and T correspond to the table. Do not rely on empirical mea-
surements. Temperature should be measured using thermometers as near as possible to the boiler,
bearing in mind the heat loss from the pipes.
• Check that the gas valve modulates correctly both during the central heating phase and the domestic
hot water production phase.
• Determine the combustion efficiency and the composition of the flue gases.
• If any of the above are not correct refer to Technical Data. Adjustment and Fault finding.
3.3 Maintenance
The following operations are strictly reserved for Qualified Personnel, such as corgi registered engineers
or Ferroli Service engineers.
Annual Servicing
The following should be checked at least once a year:
• Water pressure in the central heating system when cold should be about 1 bar. If this is not the case,
bring it back to this value.
• Check control and safety devices (gas valve, flow meter, thermostats, etc) are functioning correctly.
• The burner and heat exchanger must be clean. To avoid damage, always clean them with a soft brush
or compressed air. Never use chemical products.
• The expansion vessel must be checked (precharge 1 bar).
• Check there are no leaks in the gas and water circuits.
• Check the air-flue gas duct terminal is free from obstructions and sound.
• The electrodes must be free from corrosion build up and correctly positioned.
• Gas flow and pressure must correspond to the values given in the Technical Data.
• The pump must be free to rotate.
• The condensate discharge must be clean, free of obstructions and leaks.
Cleaning the boiler and burner
The boiler should be serviced annually. The heat exchanger and burner must never be cleaned with
chemical products or steel brushes. Particular attention must be paid to all seals and fixings associated
with the room-sealed compartment (gaskets, grommets, etc). Air leakage would cause pressure inside
the compartment to drop, possibly tripping the differential pressure switch and thus shutting down the
boiler. After cleaning particular attention should also be paid to checking stages of start-up and opera-
tion of the thermostats, gas valve and pump.
