Roof-Top Installation
•
NOTE: Minimum vapor-piping slope must always be maintained for all GREEN MACHINE
mounting options.
•
VST requires a minimum slope of ¼” per foot on all vapor piping away from the
GREEN MACHINE to the vent risers.
•
The GREEN MACHINE
may be installed on a station’s roof provided the structure can
support the weight of the GREEN MACHINE.
•
All safety and code concerns must be taken into consideration prior to a roof-top
installation.
•
Due to a variety of roof construction designs, VST cannot recommend how the GREEN
MACHINE should be mounted on the roof; however, the GREEN MACHINE must be installed
at a height allowing the piping inlet and outlets to be above or through the building
parapet.
•
The GREEN MACHINE
has 24” legs that can be bolted on the base, but the legs may be
removed and the GREEN MACHINE secured to a steel structure attached to the roof.
•
A new air outlet vent riser connected to the GREEN MACHINE must be installed to release
air to the atmosphere.
•
A Design Engineer is responsible for designing the support structure, support base, all
required hardware and bolting connections, and the support structure foundation to meet
all regulatory specifications that may be required by local jurisdictions.

The GREEN MACHINE
may be installed on a station’s canopy provided the structure can
support the weight of the GREEN MACHINE.
