PART II: INSTALLATION
21
The pilot gas train is already installed to the burner, the following connections must be executed:
connection from the stabiliser with filter to the gas supply network
Fig. 3 - pipe port (3) for connecting the pilot gas train to the valves group of the main gas train, for pilot gas train proving system
Abb. 1
The procedures of installation fo the gas valves are showed in the next paragraphs, according to the gas train used:
threaded gas trains with Siemens VGD20..
flanged gas trains with Siemens VGD40..
Once the gas train in installed, execute the electrical connections for all its items (gas valves group, gas proving system, pressure
switches).
Gas Filter (if provided)
The gas filters remove the dust particles that are present in the gas, and prevent the elements at risk (e.g.: burner valves, counters and
regulators) from becoming rapidly blocked. The filter is normally installed upstream from all the control and on-off devices.
OIL TRAIN CONNECTIONS
ATTENTION: it is reccomended to install the filter with gas flow parallel to the floor in order to prevent dust fall on
the safety valve during maintenance operation.
