GAS TRAIN CONNECTIONS
WARNING: before executing the connections to the gas pipe network, be sure that the manual cutoff valves are
closed.
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).
ATTENTION: once the gas train is mounted, the gas proving test must be performed, according to the procedure
set by laws in force.
CAUTION: The direction of gas flow must follow the arrow on the body of the components mounted on the gas
ramp (valves, filters, gaskets...).
NOTE: the bellows unit, the manual cutoff valve and the gaskets are not part of the standard supply
