?
Burner performs a fault lock-out after burn-
ing faultlessly in normal operation?
!
Incorrect gas and air flow rate settings.
•
Check the gas and air pressures.
!
No ignition spark is created.
•
Check the ignition cable.
•
Check the voltage supply and wiring.
•
Check whether the burner is adequately ground-
ed.
•
Check the electrodes – see page 10 (Checking
the ignition and ionization electrodes).
!
Automatic burner control unit signals a fault.
•
Check the ionization cable.
•
Measure the ionization current by connecting a
micro-ammeter into the ionization cable: min.
5 µA ionization current – stable signal.

!
Burner head dirty.
•
Clean gas and air bore holes and air slots.
•
Remove deposits on the burner head.
WARNING
Risk of injury! Burner heads have sharp edges.
!
Excessive pressure fluctuations in the furnace
chamber.

Technical data
Gas supply pressure: approx. 20 to 50 mbar,
air supply pressure: approx. 25 to 40 mbar,
each depending on flame shape, gas type and air
temperature (gas and air pressures – see operating
characteristic diagrams at www.docuthek.com).
Burner length increments: 100 mm.
Gas types: natural gas, LPG (gaseous) and coke
oven gas; other gases on request.
Heating: direct using a burner quarl or an attachment
tube, indirect using a burner attachment tube inside
the radiant tube.
Control type:
staged: On/Off, High/Low/Off,
continuous: constant λ value.
Most of the burner components are made of corro-
sion-resistant stainless steel.
Housing:
ZIO: St.
Flame control: with ionization electrode (UV sensor
as an option).
Ignition: direct spark ignition; ignition lance as an
option.
Maximum furnace temperature:
in the burner quarl: up to 1450°C (higher tempera-
tures on request),
with burner attachment tube: up to 600°C.
Maximum air temperature:
ZIO: 450°C,
ZIOW: 500°C.
