6.
Turn on the ON/OFF switch and start the boiler.
Note
During commissioning, the appliance can enter a
fault state if there are airlocks in the gas line.
Reset the appliance after approx. 5 s (see operat-
ing instructions).

7.
Measure the supply (flow) pressure. For set val-
ues, see the following table.
Note
Use a suitable measuring device with a resolution
of at least 0.1 mbar (0.01 kPa) to check the supply
pressure.
