Air Admittance Valve
Installation Instructions
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 MV 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 MV. 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 fixture 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/ fixture it is being installed to vent.
