Installation Procedure
Installing the eFlo unit consists of a mechanical installation and an electrical installation. The
mechanical installation includes mounting as well as inlet and outlet piping. The eFlo unit will
be assembled prior to shipment. Before beginning installation:
Ensure that all fittings and connections are tightly secured prior to beginning
installation.
Ensure that all expected components are present. Contact SSi at (513) 772-0060 if you
have questions.
Mechanical Installation
Clearance
When installing the device, leave enough room on either side (3” is recommended) to allow
users to adjust, remove and replace the existing fittings. Also ensure that the device is installed
in a location that allows for easy access to the power connection.
Mounting
Proper mounting is essential for the successful operation of the eFlo instrument. Please use
the mounting template (included with the eFlo unit or available at
) to ensure accuracy.
The eFlo can be supported by pipe without using the bolt holes if desired. However, if mounting
in this manner, ensure that the pipe is rigid enough to support the weight of the meter.
When installing the device, the shutoff valve or blocking solenoid should ideally be located
before the meter.
Plumbing
The outlet openings measure 1.25” NPT. Use of bushings or reducers at these connections is
acceptable as long as the smallest pipe diameter is not smaller than the installed orifice plate.
See certification for that meter to determine actual orifice diameter. Contact SSi at (513) 772-
0060 for questions about pipe sizing.
Thread Sealants:
Teflon or natural gas-rated pipe tape or pipe dope is acceptable for non-corrosive gases. For
corrosive gases, pipe tape is not recommended, unless the manufacturer specifies that it is
rated for gas(es) being flowed through the meter.
NOTE: When installing the device, ensure that excessive tape or dope does not fall into the
meter, as this can damage sensors, plug sensor lines, prevent flow through the meter, and
prevent the device from functioning properly.
