5. Checking and maintenance
5.4 Bleeding the heating system
It is essential that you vent any air in the appliance, the ducts or the
valves to prevent the noise annoyance likely to be produced during
heating or water draw-off.
To do this, proceed as follows:
1. Open the valves on all radiators connected to the heating system.
2. Set the heating set point to as high a temperature as possible.
3. Wait until the radiators are hot.
4. Switch the boiler off.
5. Wait around 10 minutes until the radiators are cold.
6. Bleed the radiators.
Start with the lower floors.
7. Open the bleed connection using the bleed key, keeping a rag
pressed against the connection.
8. Wait until water begins to come out of the bleed valve, then close
the bleed connection.
The water may still be hot.
9. Turn the boiler on.
10. Check the pressure of the installation.
If the water pressure is too low, add more water to the installation
(See Topping up the boiler with water).
11. Set the heating set point.
