Remove the measuring devices and close off the

test nipples – tighten the grub screws.

Block and seal the adjusting elements.

Induce a flame failure, e.g. by pulling the terminal

boot off the flame rod. The flame detector must
close the gas safety valve and signal a fault.

Switch the system on and off several times while

monitoring the automatic burner control unit.

Produce an acceptance report.

DAnGeR

Risk of explosion in case of CO being formed
in the furnace chamber! CO is odourless and
poisonous!

An incorrect change of the burner settings may

change the gas/air ratio and lead to unsafe operat-
ing conditions:

– All interventions may only be carried out by

qualified gas technicians.

7 MAIntenAnCe

➔

Maintenance and function check every six months.
If the media are highly contaminated, this interval
should be reduced.

DAnGeR

Risk of explosion!

– Please observe the appropriate precautions

when igniting the burner.

– Maintenance work on the burner must be

carried out by authorized trained personnel only.

DAnGeR

Risk of burning!

– Outflowing flue gases and burner components

are hot.

➔

We recommend that all the gaskets removed during
maintenance work be replaced. The appropriate
gasket set is available separately as a spare part.

Check the ionization and ignition cables.

Measure the ionization current.

➔

The ionization current must be at least 5 µA and

must not vary.

–

Disconnect the system from the electrical power

supply.

Shut off the gas and air supply – do not change

the restrictor settings.

7.1 Checking the spark electrode and flame

rod

➔

Ensure that the electrode length does not change.

Remove dirt from electrodes or insulators.

If the star

or insulator

is damaged, replace the

electrode.

➔

Before changing the electrode, measure the total
length

Connect the new electrode with the spark plug

using the dowel pin

Adjust spark plug and electrode to the measured

total length

➔

Turning the spark plug makes it easier to feed the

electrode into the burner insert.

7.2 Checking the burner

Removing and installing burner insert BICW

➔

Do not damage the surface of the insulation.

➔

Avoid the formation of dust.
