SUPPLY LINE
The basic diagram of the gas supply line is shown in the figure
below.
DANGER / CAUTION
Install a manual on/off valve upstream of the gas valve ac -
cording to the layout shown in the diagram illustrating the
gas train principle.
If the gas train is equipped with a pressure regulation device not
integrated 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 sta-
biliser installation point and the burner. This pipe must have a
diameter equal to or greater than the connector to the burner.
• To ensure optimal operation of the pressure regulator, it should
be applied 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 outgoing pressure must be adjusted to a value slight-
ly below the maximum possible value (the value obtained by
screwing in the adjustment screw almost completely); in this
case, the outgoing regulator pressure increases as the adjust-
ment screw is tightened, and decreases as it is slackened.
