GB-14

•

Check the electrode – depending on the burner

construction stage – 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 burner adjustment – see page 6

(Preparing commissioning).

Incorrect burner adjustment – gas volume re-
leased too quickly, defective or incorrectly set
damping unit on the solenoid valve.

•

Check solenoid valve.

•

Note the solenoid valve operating instructions.

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 Elster Kromschröder for control concepts.

Accessories

Flue gas guide tube FGT-Set . .D



Burner seal



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.

Flue gas connector FLUP

The FLUP is not supplied with the ECOMAX

and

must be ordered separately.
If the FLUP is ordered with the ECOMAX

, it will be

supplied ready-fitted on the burner.
