DANGER!
High voltage on the bare ignition electrode!
Pilot burner is only permitted to be operated with correct earthing.
With version C in particular there is a danger of death when removing or omitting the earth-
ing, the housing earthing must be connected directly to the ignition transformer earthing!
In the event of damage to the earthing insulation, the device should be shut down; further
operation without repair is not permitted.
NOTICE
Higher pressure ratings can be realised by connecting a restrictor upstream.
