• Check whether the burner is adequately ground-
ed.
•
Check the electrode – see page 10 (Mainte-
nance).
! Defective insulator on the electrode, ignition spark
jumps over incorrectly.
•
Check the electrode – depending on the burner
construction stage.
? Burner flame ignites with a loud bang?
! Incorrect electrode adjustment.
•
Check the electrode – depending on the burner
construction stage – see page 10 (Mainte-
nance).
! Incorrect burner adjustment – air volume too low
or too high.
• Correct the burner adjustment – see page 7
(Preparing commissioning).
! Incorrect burner adjustment – gas volume re-
leased too quickly, defective or incorrectly set
damping unit on the solenoid valve.
• Check the solenoid valve.
• Reduce the start gas rate.
• Adjust the damping speed, see Operating in-
structions VAS, VCS, VAS..L.
• ECOMAX ® 0C: if the burner still ignites with a
loud bang after the damping speed has been
adjusted, set pre-ventilation to 0.5 s using the
BCU (parameter 37).
! Excessive central air volume for LPG operation.
• Carefully restrict the central air at the adjust-
ing cock. Excessive restriction may cause soot
formation.
? 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.
! Automatic burner control unit signals a fault.
• Check the ionization cable.
• Check the ionization current. The ionization cur-
rent must be at least 5 µA – stable signal.
! Mixing device or swirl plate soiled.
• Clean gas and air bore holes and air slots.
• Remove deposits from mixing funnel or swirl
plate.
! Excessive pressure fluctuations in the furnace
chamber.
• Ask Honeywell Kromschröder for control con-
cepts.

 Burner gasket
 Flue gas guide tube FGT
 Mounting gasket
For a direct heating system a flue gas guide tube FGT
is required.
The FGT set..D is not supplied with the ECOMAX ®
and must be ordered separately. If the FGT set..D
is ordered with the ECOMAX
® , it will be supplied
ready-fitted on the burner.
Flue gas eductor EJEK
The eductor generates a negative pressure with a
centrally positioned nozzle and thus draws the flue
gases through the burner’s heat exchanger.
The EJEK is not included in the delivery and must be
ordered separately.
