“Wands” are direct spark ignition devices combining central spark rod, insulator and ground wire into a single, small diameter device. Ignition occurs between a central rod and the outer tubing; insulation between the electrode and the outer tubing is done through a one piece ceramic insulator in aluminium fixed to the outer tubing with a special heat resistant silicone paste. This allows for a very small-sized electrode. “Wands” may be used for detection, too. Connection to burner is through threaded connection in the desired position for compression of a threaded locking ring.
