19.4 Vapour exhaust from the cooking chamber
Exhaust gases may be wet and reach high temperatures. Therefore, do not use tubes made of materials not
ensuring absolute thermal stability up to 250ºC to channel exhaust gases.
A condenser enabling the condensation of vapours and exhaust of those vapours into a drainage may be adapted
to treat cooking vapours.
Important: Do not channel the vapour exhaust from the cooking chamber more than 50 centimeters due to risk of
condensation. This pipeline should be vertical and as straight as possible.
19.5 Gas connection
For any information related to the installation of gas appliances (connection to the supply line, smoke
evacuation, regulation, etc.), please refer to the corresponding section specified in the document "TECHNICAL MANUAL
FOR GAS OVEN INSTALLATION".
19.5.1 Connection for flue gas evacuation
All the information specified in this section is for the information of the final user.
The gases resulting from the combustion of the gas must be evacuated to the outside by installing a chimney with a
natural draft, or by placing the oven under an extraction hood.
Type evacuation B23: by this procedure, 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 90º. The first section of the installation
must be straight and vertical, with a length not less than 1 mm. The section of the pipe must be the same throughout the
installation, and it 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.
