Italy has been making extensive use of NGV for at least 40years.Today many Governments are becoming increasingly aware of thebenefits in contributing in energy security, to the economy and to theenvironment advantages when using NGV.NGV is a renewable source of fuel, the availability of the fuel makes it veryattractive for use as a substitute for traditional fuels, such as petrol anddiesel.The installation of an NGV system, even thought it is a simple oncetrained, does require technical expertise. The ability of a well trainedtechnician will guarantee the compliance with the regulations in force withsafety and professionalism.It is necessary for the NGV installer to understand the characteristics of this fuel, and to have an in-depth knowledge of the components of thesystem so as to be able to install it correctly and carry out programmedperiodic maintenance.This manual is designed to provide basic knowledge of the lo. gas s.r.l  .NGV system in order to provide the first approach to our innovativeequipment. lo. gas s.r.l  guarantees the installer with the necessary basicinformation useful to successfully install an NGV system, and to performedits maintenance in a professional way.
