Attention
• TurboVent must be installed in a location with
proper air circulation.
• TurboVent must be installed in the upright and
vertical position, not exceeding 15° from plumb
vertical alignment.
• TurboVent must be installed in a location
accessible to inspection and maintenance, such
as underneath a sink, in attic spaces, in an
access box, or in a drop-ceiling.
• TurboVent should not be subjected to outdoor
temperatures or elements. Installed vent must
remain within –40° F to 150° F.
• TurboVent must be installed at least 4" above
the trap weir.
• TurboVent must be installed 6" above insulation
material in attic installations.
• An AAV shall not be used as a relief vent, in
chemical waste systems, or within plenums.

Notes
• Sioux Chief Manufacturing has developed the
TurboVent line of air admittance valves (AAVs) in
compliance with plumbing codes, which require at least
one primary drainage vent extending to the outdoors for
positive pressure relief.
• Be sure to follow all local plumbing codes when
installing a TurboVent AAV. Verify installation is to all
mentioned manufacturers instructions, restrictions, and
notes.
• All Sioux Chief AAVs are optional replacements for
secondary venting within the plumbing system. The
TurboVent acts as a vent terminal in a drainage, waste,
and vent (DWV) system instead of extending piping to
the outdoors.
• AAVs are engineered and listed to handle a certain
xture load, in stack or individual branch applications,
which is represented on the top of each unit. Verify any
application is consistent with minimum standards for
piping installations and drainage output of the device/
xture it is being installed to vent.
