ASSEMBLING THE GAS TRAIN
The EN 676 approved gas train is sold 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).
The gas train can be assembled in different ways: (8), (8a) .
