1. 

Check the electrodes for wear and
contamination.

2. 

Clean the electrodes with a small
brush (not with a wire brush) or sand
paper.

!

Please note

Do not damage
the wire gauze.

3. 

Check the electrode gaps. If the gaps
are not as specified or the electrodes
are damaged, replace and align the
electrodes together with new gas-
kets. Tighten the electrode fixing
screws with 2 Nm.

Cleaning the combustion chamber/heat exchanger and installing
the burner

!

Please note

Scratches on parts that are in contact with flue gas can lead to corrosion.

Never use brushes to clean the heat exchanger.
