Maintenance instructions
7.3.1
Check the hydraulic pressure
1. Checking the hydraulic pressure in the installation.
2. If the hydraulic pressure is less than 0.08 MPa (0.8 bar), top up the level of water in the heating installation so that the
hydraulic pressure is between 0.15 and 0.2 MPa (1.5 and 2.0 bar).
3. Carry out a visual check for any water leaks.
7.3.2
Topping up the installation with water
1. Open the valves on all radiators connected to the heating system.
2. Set the room thermostat to as low a temperature as possible.
3. Put the boiler in shut-down/frost protection mode.
4. Open the fill valve.
5. Close the filling valve when the pressure gauge shows a pressure of 0.15 MPa (1.5 bar).
6. Put the boiler in heating mode.
7. When the pump has stopped, vent again and top up the water pressure.
Important
Filling and venting the installation twice a year should be sufficient to obtain an adequate hydraulic pressure. If it is
often necessary to top up the installation with water, contact your installer.
7.3.3
Chimney sweep instructions
