To mount the gas train, proceed as follows:
1) in case of threaded joints: use proper seals according to the gas used; in case of flanged joints: place a gasket between the ele-
ments;
2) fasten all the items by means of screws, according to the diagrams showed, observing the mounting direction for each item;
NOTE: the bellows unit, the manual cutoff valve and the gaskets are not part of the standard supply.
ATTENTION: once the gas train is mounted according, the gas proving test mus be performed, according to the
procedure set by the laws in force.
ATTENTION: it is recommended to mount filter and gas valves to avoid that extraneous material drops inside the
valves, during maintenance and cleaning operation of the filters (both the filters outside the valves group and the
ones built-in the gas valves).
