Resetting temperature limits
An activated temperature delimiter on the
downpipe is indicated by the lighting of an
"ALARM" indicator with a solid bar.
The temperature delimiter has to be
manually reset before the burner
can be used again. Investigate
and correct the reason that
the temperature delimiter was
activated.
In order to reset the temper-
ature delimiter, the burner
must fi rst be deactivated.
Then the temperature
delimiter's casing on the
downpipe has to be removed. Resetting is done by activating
the button on the temperature delimiter. Remount the casing
and restart the burner.
