Vent connection:
• 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.
Gas connection:
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.
