Maintenance
We recommend a function check every six months.
If the media are highly contaminated, this interval
should be reduced.
DANGER
Maintenance work on the burner must be carried
out by authorized trained personnel only.
Risk of explosion!
Please observe the appropriate
precautions when igniting the burner.
Risk of poisoning!
Open the gas and air supply
so that the burner is always operated with excess
air – otherwise CO will form in the furnace chamber.
CO is odourless and poisonous! A flue gas analysis
is to be conducted.
Risk of burning!
Outflowing flue gases and burner
components are hot.
▷
We recommend that all the seals removed during
maintenance work be replaced. The appropriate
seal set is available separately as a spare part.
Check the ionization/ignition cable.
Measure the ionization current.
▷
The ionization current must be at least 5 µA and
must not vary.
▷
Read off the ionization signal on the burner con-
trol unit.
Disconnect the system from the electrical power
supply.
4
Shut off the gas and air supply – do not change
the restrictor settings.
5
Disconnect the gas line from the gas insert.
6
Disconnect the grounding cable.
Checking the spark electrode and mixing
device
▷
The complete gas insert must be removed to
check the spark electrode and mixing device.
