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.

5.2 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
1. Remove the grids, burner caps and
flame-spreader crowns to access the
burner cups.
2. Replace the nozzles using a 7 mm socket
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.
