15. ANNUAL SERVICING
Burn Hazard!
Wait for the appliance to cool down before working on the parts exposed to heat
DANGER
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.
Burn Hazard!
Do not clean the boiler with abrasive, aggressive and/or easily flammable substances (such as petrol,
acetone, etc.).
To optimize boiler efficiency, carry out the following annual maintenance:
•
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;
•
Check for any impurities inside the combustion chamber. Use a vacuum cleaner to do this;
•
Check the pressure of the heating system;
•
Check the pressure of the expansion tank;
•
Check the fan works correctly;
• Make sure the flue and air ducts are unobstructed;
•
Check for any impurities inside the condensation trap;
• Check the magnesium anode, where present, for boilers fitted with indirect storage tanks.
