Electric shocks can be fatal!
– Before working on possible live components,
ensure the unit is disconnected 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.

➔
Install the ionization cable well away from mains
cables and interference from electromagnetic
sources and avoid external electrical interference.
Max. length of ionization cable – see automatic
burner control unit operating instructions.
➔
Connect the flame rod to the automatic burner
control unit via the ionization cable.

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.

A ≥ 7.5 kV, ≥ 12 mA ignition transformer is recom-
mended; 5 kV for integrated pilot.

Connect the PE wire for burner ground to the burn-
er insert. In the case of single-electrode operation,
route the PE wire from the burner insert directly to
the terminal on the automatic burner control unit.

High-voltage risk!
– It is essential that a high-voltage warning label
be attached to the ignition cable.

Risk of explosion!
– Please observe the appropriate precautions
when igniting the burner.
– Pre-purge the furnace chamber or radiant tube
with air (5 x volume) before every ignition
attempt.
– Fill the gas line to the burner carefully and
correctly with gas and vent it safely into the
open air – do not discharge the test volume into
the furnace chamber.

Risk of poisoning!
– Open the gas and air supply so that the burner
is always operated with excess air – otherwise
CO will form in the furnace chamber. CO is
