- Check that the supply voltage is 230 V - 50 Hz.
- Make sure the system is full of water (water pressure 0.8-1 bar);
- Make sure any cut-off valves in the CH and DHW systems are
open.
- Make sure the fuel supply tap is open.
- Switch on the main switch.
- Check that the safety valve is not blocked.
