18. ANNUAL SERVICING
The service must be performed only by qualified and competent staff in accordance with the Gas safety, Installation and use
regulations. In UK this person need to be approved by the Health and Safety Executive. To optimise boiler efficiency, carry out the
following at the annual service:
• 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 (system);
• Check the fan works correctly;
• Make sure the flue and air ducts are unobstructed;
• Check for any blockages inside the siphon.
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.
18.1 CLEANING THE CONDESATE TRAP
Unscrew the lower section of the water condense trap "A".
• Clean the bottom of the trap by flushing it out with water.
• Fill the lower section with water until about 10 mm below the upper
edge.
• Fasten the lower section onto the condense trap again.
Do not operate the boiler with empty condense trap to avoid risk
of poisoning through the gas combustions.
18.2 CLEANING THE HEAT EXCHANGER FUMES SIDE
Before starting to clean the heat exchanger, wait until the temperature is lower than 40°C and protect all the electric components
against splashes of water.
Proceed as follows to clean the heat exchanger:
• Disconnect the boiler from the mains power supply.
• Close the gas inlet valve.
• Remove the front cover from the boiler.
• Lower the electrical box, ensuring it is protected against contact
with water.
• Disconnect the cables of the ignition electrode, the flame sensing
electrode, and the heat exchanger flange thermostat.
• Remove the fan-mixer-burner-flange assembly, unscrewing the 6
nuts M6 and the connector under the mixer.
• Protect the rear insulating panel (2) against water with a waterproof
film, available in the cleaning kit.
• Accurately suck up the residue inside the combustion chamber and
remove any scale, using a brush with plastic bristles available in
the cleaning kit.
• Sprinkle the surfaces to be cleaned (1) generously with the
appropriate liquid BX-HT Cleaner or similar using the appropriate
spray bottle and wait 10 minutes (other products may be used,
after consulting the authorised technical assistance service).
Brush without rinsing and apply BX-HT Cleaner again. Let 10 more
minutes pass, then brush again. If the result is not satisfactory,
repeat the operation.
• When cleaning is finished, rinse with water.
• Replace the gasket of the burner support flange.
• To reassemble, proceed in the inverse order, tightening the 6 nuts
of the flange with a torque of 5.5 Nm.
