The integrated protection system only protects the boiler, not the installation. To protect the installation, set the appliance to HOLIDAYS mode. The HOLIDAYS mode protects: 4 The installation if the outside temperature is lower than 3°C (factory setting).
5. Checking and maintenance AFC 18 - AFC 24 - AFC 30 5 Checking and maintenance 5.1 General instructions The boiler does not require a lot of maintenance. Nevertheless, we recommend having the boiler inspected and serviced at regular intervals. 4 Maintenance and cleaning of the boiler must be carried out at least once a year by a qualified technician. 4 Have the flues swept at least once a year or more, depending on the regulations in force in your country.
5. Checking and maintenance AFC 18 - AFC 24 - AFC 30 4 Carry out a visual check for the presence of any water leaks. T001507-B 4 Open and close the radiator valves several times a year (this prevents the valves from seizing up). 4 Clean the outside of the boiler using a damp cloth and a light detergent. 1 2 CAUTION 3 4 T000181-B 5.3 Only a qualified professional is authorised to clean the inside of the boiler.

5. Checking and maintenance AFC 18 - AFC 24 - AFC 30 5. To add water, use the filling pipe with a valve fitting, a cloth and a venting spanner. C003835-A 6. Connect the filling tube to a (cold) water tap. T000846-A 7. Eliminate the air from the filling tube. Slowly fill the tube with water. Hold the end of the tube up, above a bucket. Turn off the tap as soon as water runs out of the pipe. C003836-A 8. Unscrew the plug from the filling/draw-off valve.
5. Checking and maintenance AFC 18 - AFC 24 - AFC 30 9. Attach the tube to the filling/draw-off valve. Firmly tighten the nut on the filling tube. 10.Open the filling/draw-off valve on the heating system. 11.Open the running water tap. 12.Check the water pressure in the installation shown on the control panel display. 13.Close the water tap when the water pressure reaches 2 bar. C003837-A 14.Close the filling/draw-off valve on the heating system.
5. Checking and maintenance AFC 18 - AFC 24 - AFC 30 6. Bleed the radiators. Start with the lower floors. 5 3 4 1 2 T000854-A 7. Open the bleed connection using the bleed key provided whilst keeping a rag pressed against the connection. T000217-A 8. Wait until water comes out of the bleed valve and then close the bleed connection. CAUTION The water may still be hot. 9. Switch on the boiler. 10.Check whether the pressure in the installation is still sufficient.
AFC 18 - AFC 24 - AFC 30 5. Checking and maintenance 11.Set the heating set point. 5.5 Draining the installation It may become necessary to empty the water from the heating system when the radiators have to be replaced, should there be a major water leak or a risk of frost. To do this, proceed as follows: 1. Open the valves on all radiators connected to the heating system. 1 2 3 4 T000181-B 2. Switch off the boiler electrical power supply. 3. Wait around 10 minutes until the radiators are cold.
