3.0 GAS TRAIN CONNECTIONS
The diagrams show the components of the gas trai included in the delivery and which must be fitted by the installer.The diagrams are in
compliance with the current laws.
3.1 Gas Filter
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.
3.2 Assembling the gas grain
To assemble the main gas train, proceed as follows:
Fig. 4 - Example of 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. 4) between the elements
NOTE: the bellows unit, the manual valve and the gaskets are not part of the standard supply.
ATTENTION: BEFORE EXECUTING THE CONNECTIONS TO THE GAS PIPE NETWORK, BE SURE THAT THE
MANUAL CUTOFF VALVES ARE CLOSED.
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.
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.
