Accessories; Flue Gas Eductor Ejek - Honeywell ECOMAX Operating Instructions Manual

• 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.

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
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.
