4 Operating the boiler
4.1
Commissioning the boiler
1. Check the water pressure in the heating system.
If the water pressure is lower than 0.8 bar, more water
should be added. If necessary, top up the water level in the
heating system (recommended hydraulic pressure
between 1 and 2 bar).

See chapter: "Filling the system", page 15
2. Open the gas valve on the boiler.
3. Turn the boiler on.
4. The boiler will begin an automatic venting-programme (which lasts
approx. 4 minutes) and will do this every time the power supply is
isolated. Both push buttons on the instrument panel light up green
during the venting cycle.
The current operating condition of the boiler is shown by the status
signal on the instrument panel. The status signal for the
B
button
can flash in a range of colours and at different frequencies. The
meaning of these signals can be found in the User instruction card
supplied with the boiler.
