Only with burner controls of the 01
series.
This circuit change (linking terminals
17 and 18) reduces the preignition
time by 50 %.
Extension of the safety time is only permitted if in compliance with the
relevant national standards.

If the case of burners with no air
damper (or with an air damper not
controlled and monitored by the
burner control), terminals 8 and 6
must be linked, as otherwise the
burner control will not be able to start
the burner.
