ignition. At a minimum ionisation current of 3 µAmp
the safety gas valve will open. The boiler is on.
9. Let the boiler run for a couple of minutes to get rid
of air in the gas pipe.
10. Set the correct burner pressure.
11. Check the thermostats for correct operation.
12. Check the fl ame protection, by starting the ionisation
probe disconnected.
13. Send the commissioning reports to Broag.
