Checking the thermal discharge valves

Perform a visual inspection of the two thermal
discharge valves. The outlets of the thermal discharge
valves must not drip.

Check function of safety devices in fuel path

Check the safety devices in the fuel path, such as the
temperature-monitoring system, the manually
operated extinguishing system or the automatic extin-
guishing system.

Also check malfunction indicators and alarms, for
example if messages from the boiler room are
displayed elsewhere.

Switch the boiler on via the mains switch and start
de-ashing.

Establish the boiler's power supply at the mains switch.
Press the [De-ash]

button to de-ash the boiler.

Switch the boiler back on with the On/Off
switch.
