ASSEMBLY INSTRUCTIONS
If the optionally available extension tubes are used, the extension tube is first screwed into the thread of the junction box. Then the
cover of the junction box is unscrewed. The red high-voltage cable from the ignition tip adapter is pulled through the extension tubes
into the junction box. The ignition tip adapter is then screwed into the extension tube. If no extension tube is used, the ignition tip
adapter is screwed directly into the junction box.
The red high-voltage cable is to be shortened in the junction box so that approximately 8 cm (measured from the bottom of the junc
-
tion box) remain. The insulation is stripped down to about 1 cm at the ends of the red and brown lines. The wires of the high-voltage
cables are inserted into the rotary connector (supplied with the junction box) up to the stop and contacted by turning the connector
clockwise.

to the ignition unit
The cover of the junction box is screwed on again in the last step.
The ignition tip HE-S or HE-L has to be screwed into the ignition tip adapter.
For personal protection and for later use, it is recommended to connect a protective conductor (minimum cross-section 4mm²)
to the external PE connection bolt of the junction box with a grounding clamp for connecting the ground potential to the burner
(see installation instructions described below).
Protective conductor assembly
The insulation of the PE wire must be offset by approx. 8mm at the end. The supplied yellow ring cable lug
(4 mm²) is fitted here with crimping pliers (model for insulated ferrules with forced lock). The yellow ferrule is placed on the external
grounding bolt on the housing and secured with the washer and serrated lock washer and a nut.
On the other side of the PE cable, a grounding clamp should be connected to metal surfaces grounded on the system side for easy
handling to ensure good contact.
A ready-made PE cable with mounted grounding clip is available as an accessory (HEP-2-CLIP).
