Installing the burner insert
▷
The burner insert can be rotated to the required
position in increments of 90°.
▷
Insert the gas housing gasket between the
burner insert and the air housing.
▷
On ZIOW, avoid the formation of dust and do
not damage the surface of the internal insulation.

▷
Tighten the burner insert in a crosswise fashion
with max. 37 Nm (27.3 lbf ft).

DANGER
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is discon-
nected from the power supply.
▷
For the
ignition and ionization cables
, use (un-
screened) high-voltage cable:
FZLSi 1/6 up to 180°C (356°F),
Order No. 04250410, or
FZLK 1/7 up to 80°C (176°F),
Order No. 04250409.

Ionization electrode I
▷
Install the ionization cable well away from mains
cables and interference from electro-magnetic
sources and avoid external electrical interference.
Max. length of ionization cable – see automatic
burner control unit operating instructions.
▷
Connect the ionization electrode to the automatic
burner control unit via the ionization cable.
Ignition electrode Z
▷
Length of ignition cable: max. 5 m (15 ft), recom-
mended < 1 m (40").
▷
For permanent ignition, max. ignition cable length
1 m (40").
▷
Lay the ignition cable individually and not in a
metal conduit.
▷
Install the ignition cable separately from ionization
and UV cables.
▷

≥
7.5 kV,

Connect the PE wire for burner ground to the
burner insert. In the case of single-electrode op-
eration, route the PE wire from the burner insert
directly to the terminal on the automatic burner
control unit.
WARNING
High-voltage risk! It is essential that a high-voltage
warning label is attached to the ignition cable.

For more detailed information on how to wire
the ionization and ignition cables, refer to the
operating instructions and connection diagrams
of the automatic burner control unit and ignition
transformer.
