The frequency of the boiler maintenance must comply with current law and, nevertheless, should be
carried out once a year.
In order to guarantee the long life of the appliance and in accordance with the current gas safety
regulations, only use original spare parts.
Before carrying out any type of maintenance operation, disconnect the appliance from the mains
electricity supply and close the gas valve.
6.2 Boiler inspection
In order to ensure that the boiler operates efficiently and safely, it is recommended that the appliance is inspected
by a suitably competent technician at least once a year.
The following operations should be carried out annually
■ Check the condition of the gas seals and replace where necessary.
■ Check the condition of the water seals and replace where necessary.
■ Visually inspect the condition of the combustion chamber and flame.
■ When required, check that the combustion is correctly regulated and if necessary proceed in line with section
“Commissioning the boiler”.
■ Remove and clean any oxidation from the burner.
■ Check that the seal of the room-sealed chamber is undamaged and positioned correctly.
■ Check the primary heat exchanger and clean if necessary.
■ Check the maximum and minimum modulation pressures and the modulation itself.
■ Check the condition and operation of the ignition and gas safety systems. If necessary, remove and clean the
scaling from the ignition and flame detection electrodes, paying particular attention to replace them at the correct
distance from the burner.(
Check the positions of the electrodes, especially the ignition electrode). Make sure
that there is a gap of 3 mm between the two ignition electrodes, which should be 10 mm from the burner. )
■ Check the heating safety systems: temperature limit safety thermostat, pressure limit safety device.
■ Check the pre-fill pressure of both the system and the DHW expansion vessels.
■ For safety reasons, periodically check the integrity and operation of the flue gas exhaust system.
■ Check that the connection to the mains electricity supply complies with that reported in the boiler’s instruction
manual.
■ Check the electrical connections inside the control panel.
■ Check the D.H.W flow rate and temperature.
■ Check that the condensate drain system is working correctly, including any parts of the system outside the boiler
such as condensate collection devices along the length of the flue and/or any acid neutralising devices.
■ Check that the condensate flows freely and that there are no exhaust fumes present within the appliance.
■ Check the condition of the sacrificial anode installed at the top of the cylinder
