SUPPLY LINE
The figure below shows the gas supply line block diagram.
The gas train is certified in compliance with EN 676 Standard and
supplied separately from the burner.
To ensure optimal functioning of the pressure regulator, it should be
applied to the horizontal pipe after the filter.
The gas pressure regulator must be regulated when the burner is
working at the maximum flow.
The delivery pressure must be adjusted to a level slightly below the
maximum attainable (i.e. that obtained when the regulation screw is
screwed in almost fully).
DANGER / ATTENTION
Install a manual shut-off valve and a vibration-proof joint
upstream of the gas valve, according to the layout shown in the
block diagram.
