Danger of death from poisoning by flue gas due 
to inadequate combustion

Danger of death due to flue gas leak. If flues are 
damaged or leaking, or if you smell flue gas, observe 
the following rules.

▶ Close the fuel infeed.
▶ Open doors and windows.
▶ If necessary, warn all residents and leave the 

building.

▶ Prevent third parties from entering the building. 
▶ Rectify any damage to the flue gas pipe 

immediately.

▶ Check the combustion air supply.
▶ Do not cover or reduce the size of ventilation 

openings in doors, windows and walls.

▶ Ensure that there is adequate combustion air 

supply, including for any appliances installed at a 
later date, e.g. extractor fans, kitchen fans or air 
conditioning units that discharge air to the outside.

▶ Never operate the device if there is insufficient 

combustion air supply.

Electrical work

Electrical work must only be carried out by electrical 
installation contractors.

Before starting electrical work:
▶ Isolate all poles of the mains voltage and secure 

against reconnection.

▶ Make sure the mains voltage is disconnected.
▶ Observe the wiring diagrams of other system 

components as well.

 Packaging

The following points should be observed during 
unpacking.
▶ Check the delivery immediately upon receipt for 

completeness and possible transport damage.

▶ In the event of transport damage, the delivery 

should only be accepted conditionally.

▶ Do not use damaged components for assembly.
▶ Carefully unpack the unit.
▶ Ensure that all packaging material is removed and 

that the unit is free from all materials that may 
prevent the unit from operating correctly.

according to the manufacturers instructions.
