Procedure:
CAUTION!
Residual heat on all parts of the system and the pilot burner.
Risk of contact burns.
Allow the system and pilot burner to cool down before removal.
1 Shut down the system and secure it from being switched on again.
2 Allow the pilot burner to cool down completely.
3 Shut off the gas and air supply.
4 Depressurise the gas and air supply systems and disconnect them.
5 Have the closures for the combustion chamber opening ready.
6 Disconnect the electrical connections and ensure that there is no voltage present.
7 Loosen the grub screws.
8 Pull the pilot burner out of the flange.
Remove the device
NOTICE
If the location conditions permit, it makes sense to remove the device together with the feed-
through flange.
Advantage: The position of the outer tube in the feed-through flange is maintained without any
changes.
Alternatively, the outer tube with feed-through flange and air enclosure can remain on the
combustion chamber so that only the electrodes need to be pulled out of the outer tube.
Requirement for this: The outer tube is short enough that the electrode rods can be removed
from the outer tube without twisting.
Fig. 6-2 Leave outer tube and feed-through flange on the combustion chamber
1 Mark the position in which the outer tube is
inserted in the feed-through flange.
2 Loosen the grub screws of the feed-through
flange.
3 Pull the pilot burner out of the feed-through flange.
