Vent Line Labeling and Install Considerations
The vent line contains significant amounts of EO during the Gas Removal and Flushing stages. Ensure
the vent line is gas tight from the GS Series sterilizer to the outside atmosphere and is labeled to
indicate EO. A separate vent line to the outside is required. The vent line should terminate away from
areas where people walk or work and should be located at least 7.6 m (25 ft) away from the building
air intake source.

Do not terminate the vent line within 7.6 m (25 ft) of any possible source of ignition or any opening to
the building interior such as fresh air inlets, unsealed windows, or pedestrian traffic areas. The inlet
assembly, from the Vent Line Installation Kit, must be installed within 91.44 cm (3 ft) of the
sterilizer's EO port in a position that is accessible to 3M Health Care service personnel (Figure 10).
The single vent line is run directly to the exterior or to the 3M Abator using the appropriate connection
fittings. When the 3M Abator is installed, run the vent line from the vent outlet port on the 3M Abator
to the outside. Shut off valves in the vent line are not recommended.
