Make sure that the gas pipe does not pass near hot areas and that it is not exposed to possible tractions,
torsions or crushing.
The gas supply pipe (rigid or flexible) must comply with current national regulations and, in addition, must
undergo appropriate periodic inspections, as well as be replaced if necessary.
12.5.1 Connection for flue gas evacuation
The gases resulting from the combustion of the gas must be evacuated to the outside by installing a chimney with
natural draft, or by placing the oven under an extraction hood.
Type evacuation B11: by this way, the combustion gases are evacuated to the outside through a natural draft
chimney provided with a non-return valve. The installation must have a minimum ascending slope of 10% and, in case
there are curved sections, they must be trolleyried out at angles not less than 90 °. The first section of the installation
must be straight and vertical, with a length not less than 1m. The section of the pipe must be the same throughout the
installation, and must not be provided with sections with a lower section than the connection of the discharge pipe. If
there is a need to install a horizontal section, it should not exceed 1.5m.

It is advisable to install a cap at the end of the chimney in order to prevent rainwater from entering the device and
prevent possible air returns caused by strong wind.
The temperature of the flue gases can reach 500 °, so we recommend using stainless steel pipe or similar material
resistant to high temperature.
