To assemble the main gas train, proceed as follows:
Fig. 8 - Example for gas train
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. 8) between the items
2)
fasten all the items by the screws, according to the shemes shown, observing the mounting direction for each item (see figure
above).
NOTE:
the bellows unit, the manual vale 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 MBC..SE 1200 or Siemens VGD20..
z
flanged gas trains with Multibloc Dungs MBC..SE 1900-3100-5000 or Siemens VGD40..
ATTENTION:
once the gas train is mounted according to the diagram on Fig. 8, the gas proving test mus be performed,
according to the procedure set by the laws in force.
