Depending on the operation conditions the units are to
be tested by an expert when necessary, but at least re-
gularly every two years, to ensure their safe operation.
The test result is to be recorded in a test certificate
which is to be safely kept until the next test so that it
can be presented to the authorized persons for control
purposes at any time.
If any faults are stated the supervisor is to be informed.
If the faults affect the unit’s operational reliability, ope-
ration is to be stopped!
Regular maintenance and care, at least after each
heating period is the basic condition for a long servi-
ce life and a faultless operation of the unit.
Make sure to keep the unit free from dust and other
deposits and to clean it only with a dry or humid cloth
(do not use water jet).
Do not use sharp or solvent-containing cleaning a-
gents.
Check suction and blowing out lattice regularly to
see whether it is dirty and clean it, when necessary.
Check the suction opening for combustion air as well
as the injector fitted behind it and the gas nozzle re-
gularly to make sure that they are not dirty.
Check gas hoses and sealings to see whether they
are damaged and replace when necessary.
Clean gas burner and gas nozzle regularly.
Clean baffle plate regularly.
Check ignition electrode and set when necessary.
Check thermocouple and clean when necessary
The bi-metal spring may neither be damaged nor
bent in or order not to affect the function of the tem-
perature-limiter!
When the unit is being maintained, set or
repaired, the gas supply has to be cut off and
the mains plug has to be unplugged from the
mains socket!
Setting and maintenance work is to be carried
out only by authorized specialists!
