How do I fit and use your GAS IT Autochange over valve?

The GAS IT Auto change over valve is designed to connect to your existing bulkhead gas regulator via the W20 fitting where a single pigtail usually connected to  ( it is not a regulator itself ) and allows 2 gas bottles or gas tanks to be connected to one gas pressure regulator.  When one bottle or tank becomes empty the auto change over valve switches seamlessly from the empty bottle/tank to the full one and at the same time the dial on the auto change over valve changes from green to red indicating to you that it has changed to the next bottle/tank.

The Auto change over is designed to sit on top of your existing bulkhead regulator via an included W20 x W20 brass fitting. The overall length of the Auto changeover is approximately 100 mm / 4 inches so If the space above your regulator is restricted and the changeover valve will not fit there, you can purchase a W20 to W20 90 degree elbow from the GAS IT web shop to move it outwards ( GAS IT Part number for Elbow GI-ACCS-077 ).

Attached are the instructions for our GAS IT auto changeover device as manufactured by Cavagna Italy.

This automatic changeover valve is not a pressure regulator and is designed to work with your existing fitted bulkhead regulator via the W20 fitting ( where your current pigtail goes )
