Assembling the gas grain
Fig. 5 - Example of gas train
To mount the gas train, proceed as follows:
1-a) in case of threaded joints: use proper seals according to the gas used;
1-b) in case of flanged joints: place a gasket (no. 1A..1E - Fig. 5) between the elements
NOTE: the bellow joint, the manual valve 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:
z
threaded gas trains with Multibloc Dungs MB-DLE, MBC..SE 700 or Siemens VGD20..
z
flanged gas trains with Multibloc Dungs MBC..SE 1900-3100-5000 or Siemens VGD40..
MULTIBLOC DUNGS MB-DLE 415..420
Mounting
1. Loosen screws A and B do not unscrew (Fig. 6 - Fig. 7).
2. unscrew screws C and D (Fig. 6 - Fig. 7).
3. Remove MultiBloc between the threaded flanges (Fig. 7).
4. After mounting, perform leakage and functional tests.
ATTENTION: once the gas train is mounted according to the diagram on Fig. 5, 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).
