2 General Safety Instructions
2.5 Electrical Connection Flame Sensor
Interruptions and losses in signal transmission need to be minimised:
• Do not wire the sensor cable with other cables.
Flame signal is reduced through line capacities. Use a separate 7-pole cable.
• Consider the permitted length of sensor cables.
• The ionisation flame sensor supplied from the mains is not protected against contact. Pro-
tection against accidental contact is therefore obligatory.
• Ground the burner according to instructions – grounding the boiler itself is not sufficient!
• Position ignition electrode and ionisation flame sensor where spark cannot hit ionisation
flame sensor (risk of electrical overloading).
