SUPPLY LINE
The figure below shows the gas supply line block diagram.
Install a manual shut-off valve and an anti-vibration joint upstream of
the gas valve, as shown in the diagram.
If the gas train is equipped with a pressure regulation device not inte-
grated in a monoblock valve, follow the instructions below to install the
accessories on the gas pipe near the burner:
•
To avoid high pressure drops upon ignition, there should be a
1.5/2 m long pipe section between the pressure reducer or stabili-
ser installation point and the burner. The tube diameter should be
equal to or greater than the burner attachment union.
To ensure optimal operation of the pressure regulator, it should be ap-
plied to the horizontal pipe after the filter.
The gas pressure regulator must be adjusted when it is working at the
maximum output actually used by the burner.
The delivery pressure must be adjusted to a level slightly below the
maximum obtainable.
