•The steam pressure must be between 5 and 10 bars.
•Install a steam escape valve to avoid overpressure.

•For security reasons, lead the air tube to the exterior of the room.
Attention: Protect the far end of this tube to avoid possible obstruction, which would affect machine operation.
Connect the device to the existing gas conducts and install a blocking valve between the device and the rest of the installation.
The installation must be in accordance with the valid norms and regulations of the country involved.
The gas supply conducts must have sufficient dimensions to minimise pressure loss. Its diameter must be calculated as a function of its path (length, number of bends, etc.) and the power of the device.
Check that settings of device correspond to type and pressure of gas of installation.
Connect a manometer to the pressure connection situated on top of the electronic valve module when all burners are on, to check the pressure of the gas feed.
The measured gas pressure must be equal to the pressure indicated on the identification label for the used gas type.
Gas feed connection is 1 inch in diameter and in agreement with the norm ISO 228/1.
