INSTALLATION - 5991477A418/A
Extraction of the combustion products
The combustion products may be extracted by
means of hoods connected to a natural draught
chimney whose efficiency is certain or via forced
extraction. An efficient extraction system requires
precision planning by a specialist qualified in
this area and must comply with the positions and
clearances indicated by the applicable
standards.
When the job is complete, the installer must
issue a certificate of conformity.
Adaptation to different types of gas
In case of operation with other types of gas, the
burner nozzles must be changed and the
minimum flame adjusted on the gas cocks.
Replacing nozzles
A = External nozzle, B = Internal nozzle.
1. Remove the pan supports, burner caps and
flame-spreader crowns to access the burner
cups.
2. Replace the nozzles using a 7-mm wrench
according to the type of gas to be used (see
the “Burner and nozzle characteristics
table”).
3. Replace the burners in their respective
housings.
Adjusting the minimum setting for natural or

Light the burner and turn it to the minimum
position. Extract the gas cock knob and turn the
adjustment screw next to the gas cock spindle
