GAS SUPPLY LINE
The gas supply diagram is shown in the adjacent figure. The gas
train is certified in accordance with Standard EN 676 and is supplied
separately from the burner.
A manual stop valve and a anti-vibration joint must be installed as
indicated in the diagram.
If the gas train has a pressure regulator not incorporated in a
monoblock valve, we recommend that you follow this practical
advice on the installation of accessories on the gas piping close
to the burner:
• To prevent large pressure drops on ignition it is best if there is
a 1.5 to 2 m length of piping between the point of application
of the stabilizer or pressure reducer and the burner. This pipe
must have a diameter equal to or greater than the connector
to the burner.
• For a better operation of the pressure regulator it is advisable to
attach it to the horizontal piping after the filter. The gas pressure
regulator must be adjusted while working at the maximum
capacity actually used by the burner. The delivery pressure must
be adjusted to a level slightly below the maximum obtainable.
(That which is obtained when the regulation screw is turned
almost to the end); in the specific case, when the regulation
screw is tightened, the output pressure from the regulator
increases and when it is loosened it decreases.
