•
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.

Vent-Stack Mount 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 elevated on the existing vent risers provided there is
an existing structure that can support the weight of the GREEN MACHINE, or a structure can
be installed to support the weight of the GREEN MACHINE.
•
Due to a variety of construction designs, VST cannot recommend how the GREEN MACHINE
should be installed or mounted on a vent riser support structure; however, the structure
that supports the GREEN MACHINE must be designed and installed at a height allowing the
piping inlet and outlets to connect to the existing vent risers.
•
The GREEN MACHINE
has 24” legs that can be bolted on the base, but the legs may be
removed for the GREEN MACHINE to be secured to a steel support structure.
•
A new air outlet vent riser connected to the GREEN MACHINE must be installed to release
air to the atmosphere.
•
All safety and code concerns must be taken into consideration prior to vent stack mount
installation.
•
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.
