Risksfrompressurisedwater
Boilersaresubjecttohighwaterpressure.
Waterpressurecancausesevereinjuries.
Beforeworkingonpartswhichareincontact
withwater,allowtheappliancetocooltobelow
40°C,shutoffallvalvesand,ifnecessary,drain
theappliance.
Note:
Sensorscanbeincontactwithwaterandthere-
foreexposedtopressure.
Workingonthesystem
- Close the gas shut-off valve and secure it against uninten-
tional reopening.
- Isolate the system from the power supply (e.g. by remov-
ing a separate mains fuse or by means of a main switch
or a heating emergency stop switch) and check to ensure
there is no voltage.
- Safeguard the system against reconnection.
Inspectionandservice
- Ensure the correct operation of the gas boiler by having a
contractor carry out inspections at least once a year and
maintenance/repair when required.
- (DVGW - TRGI 2008 - G600).
We recommend arranging a suitable maintenance con-
tract.
- The operator is responsible for the safety, environmental
compatibility and energy quality of the heating system
(German Immission Control Act/Energy Saving Ordi-
nance) [Germany].
- Use only genuine WOLF spare parts.
