Chapter 2: Vapor Piping Installation
2 Vapor Piping Installation Overview
There are 3 piping connections to be made to the GREEN MACHINE. See Figures 2-1 & 2-2:
Vapor Inlet (supply) from the UST’s
Vapor (concentrate) Return to the UST’s
Air Outlet to atmosphere
All the GREEN MACHINE piping connections are 1” diameter National Pipe Thread (NPT).
2.1 General Notes
The piping contractor is responsible for providing all necessary piping, non-hardening pipe­joint compound, and pipe fittings.
Make sure the gasoline UST tanks vapor piping is manifolded either above ground or below ground.
Locks must be installed on the valves to prevent unauthorized tampering of the equipment.
Under normal operation, the valves must be locked in the OPEN position.
VST requires a minimum slope of 1/4” per foot on all vapor-piping away from the GREEN MACHINE to the vent risers or to any other UST piping connection.
The ¼” diameter drain line with the supplied adapter must be installed per Figure 2-1.

Chapter 2: Vapor Piping Installation Page 45
2.2 Flexible Piping
If flexible piping is required by the local authority to meet seismic requirements, install the flexible piping between the GREEN MACHINE locking ball valve and the vent riser(s).
The flexible connector must be approved for a service station above-ground application.
Support the flexible piping per manufacturer’s recommendation.
The slope of the flex connection from the GREEN MACHINE back to the vent riser must be a minimum of 1/4” per foot slope.
Liquid traps are not allowed.

Chapter 2: Vapor Piping Installation Page 46
2.3 Vapor Inlet and Vapor Return Piping Installation
Install a 1” vapor inlet pipe and a 1” vapor return pipe as shown in Figure 2-1 from the vapor inlet and vapor return connections on the GREEN MACHINE to an existing vent riser.
An existing vent riser that connects to the GREEN MACHINE must be modified by:
Adding the first tee (near the bottom of the vent riser) for connecting the 1” vapor
return pipe. The first tee must be installed to allow the vapor return to slope away from the GREEN MACHINE.
Adding a second tee/cross (just below the P/V valve) for connecting the 1” vapor inlet
pipe. The second tee/cross must be installed at the top of the vent riser, but below the P/V valve.
Both the vapor inlet and the vapor return lines have: a 1” union, a 1” locking ball valve, and a 1” tees/caps, and any other piping fittings to complete the installation.
The 1” vapor return pipe connecting to the bottom of the vent riser MUST BE INSTALLED below the 1” vapor inlet pipe that connects to the top of the vent riser.
A ¼” drain line MUST BE INSTALLED between the vapor inlet and the vapor return so any condensate from the vapor inlet line can drain into the vapor return line. VST is supplying a ¼” NPT x ¼” NPT adapter with a 0.063 orifice. The orifice will eliminate any vapor flow between
the vapor inlet line and the vapor return line.
Install a tee into the vent riser that will connect to the GREEN MACHINE Vapor Inlet using 1” NPT pipe.
The new tee must be installed to allow for slope away from the GREEN MACHINE to the vent riser.
If there are multiple-grade UST’s and multiple vent risers, VST recommends connecting the GREEN MACHINE to the lowest octane vent riser.
From the vent riser, install the 1” locking ball valve, then the 1” union, then the 1” tee. See Figure 2-1.
4.5 - GREEN MACHINE - North America - Installation, Operation, Maintenance, & Troubleshooting Manual
Chapter 2: Vapor Piping Installation Page 47
2.4 Air Outlet Piping Installation
Install a new vent riser next to an existing vent riser (if possible).
The 1” piping must slope away from the GREEN MACHINE a minimum of ¼” per foot. See Figure 2-1.
Install the new dedicated vent riser so that the discharge opening is at least as high as the existing riser and a minimum of 1” diameter.
Install a tee with a cap at the bottom of the new air outlet vent riser to provide for manual drainage, if required.
Make sure the ¼” drain line is installed between the vapor inlet and the vapor return lines.
Install piping from the 1” NPT Air Outlet fitting on the GREEN MACHINE to the new vent riser.
From the vent riser, install the 1” locking ball valve, then the 1” union, then the 1” tee as
shown in Figure 2-1.
A rain cap or equivalent must be installed on the new air outlet vent riser.
If a PV vent valve is used, the internal components must be removed to allow open venting to the atmosphere.
2.5 Vapor Piping Post-Installation
After all the piping has been installed, make sure the 3 lockable ball valves are locked and in the OPEN position.
Make sure all the pipe connections are tight.
Make sure the slope is a minimum 1/4” per foot away from the GREEN MACHINE to the vent risers.
Make sure there are no traps between the GREEN MACHINE and the vent risers.
If flex piping is used, make sure the flexible piping is adequately supported.
Make sure the ball valve below the Pressure Sensor is OPEN, or the handle is vertical. See Figure 2-3.
The ¼” diameter drain line with the supplied adapter must be installed per Figure 2-1.
