ATTENTION: once the gas train is mounted according, 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).
WARNING: Slowly open the fuel cock to avoid breaking the pressure regulator.
