20. ANNUAL SERVICING

If the boiler was operating, wait for the combustion chamber and pipes to cool down.
Before commencing any maintenance operations, make sure the boiler is disconnected from the power supply. After servicing,
reset the original operating parameters of the boiler if they were changed.
Do not clean the boiler with abrasive, aggressive and/or easily flammable substances (such as petrol, acetone, etc.).
To optimise boiler efficiency, carry out the following annual controls:
• Check the appearance and airtightness of the gaskets of the gas and combustion circuits. Replace any worn seals with new
original spares;
• Check the state and correct position of the ignition and flame-sensing electrodes;
• Check the state of the burner and make sure it is firmly fixed;
• Check for any impurities inside the combustion chamber. Use a vacuum cleaner to do this;
• Check the gas valve is correctly calibrated;
• Check the pressure of the heating system;
• Check the pressure of the expansion vessel;
• Check the fan works correctly;
• Make sure the flue and air ducts are unobstructed;
• Check for any impurities inside the siphon (for condensation boilers);
• Check the magnesium anode, where present, for boilers fitted with storage boilers.
It is advisable not to use the service cap at the base to empty and clean the siphon. Remove the siphon from inside the boiler
and clean it with a jet of water. Fill the siphon with clean water and put back in place, making sure that it is properly connected.
