31. ANNUAL SERVICE

To optimise boiler efficiency, carry out the following annual controls:
• check the appearance and airtightness of the gaskets of the gas and combustion circuits;
• 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 to the aluminium flange;
• check for any impurities inside the combustion chamber. Use a vacuum cleaner to do this;
• check the gas valve is correctly calibrated;
• check for any impurities inside the siphon;
• 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 the magnesium anode, where present, for boilers fitted with storage boilers.
WARNINGS
Before commencing any maintenance operations, make sure the boiler is disconnected from the power supply.
Afterwards, move the knobs and/or operating parameters of the boiler to their original positions.
