Assembling the gas grain
Fig. 4 - Example of gas train
To mount the gas train, proceed as follows:
1)
in case of threaded joints: use proper seals according to the gas used;
2)
fasten all the elements by means of screws, according to the schemes shown, observing the mounting directions for each ele-
ment.
NOTE:
the bellow joint, the manual cock and the gaskets are not part of the standard supply.
The procedures of installation fo the gas valves are showed in the next paragraphs, according to the gas train used:

MULTIBLOC DUNGS MB-DLE 405..412
Mounting
1. Mount flange onto tube lines: use appropriate sealing agent (see Fig. 7);
2. insert MB-DLE: note position of O rings (see Fig. 7);
3. tighten screws A, B, C and D (Fig. 5 - Fig. 6), accordind to the mounting positions (Fig. 8);
4. after installation, perform leakage and functional test;
5. disassembly in reverse order.
Once the train is installed, connect electrically all its elements: gas valves group, pressure switches, gas proving system.
ATTENTION:
once the gas train is mounted according to the diagram on Fig. 4, 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).
