TECHNICAL SPECIFICATION: The purpose of an Air Admittance Valve is to provide a method of allowing air to enter the
plumbing drainage system without the use of a vent extended to open air and to prevent sewer gases from escaping into a
building. An Air Admittance Valve is a one way valve designed to allow air to enter the plumbing drainage system when
negative pressures develop in the piping system. The device shall close by gravity and seal the vent terminal at zero
differential pressure (no flow conditions) and under positive internal pressures.

Installation: Read installation instructions prior to
use of this product. Always consult local plumbing
codes prior to installing an AAV. Individual, branch
and circuit vents are permitted to terminate with a
connection to a Sure-Vent
®
AAV. The Sure-Vent
®
AAV
will only vent fixtures that are on the same floor and
connect to a horizontal branch drain. The horizontal
branch drain shall connect to the drainage stack a
maximum of four branch intervals from the top of the
stack. The Sure-Vent
®
AAV should be located within
the maximum developed length permitted for the vent.
The Sure-Vent
®
AAV must be located a minimum of 4
inches above the horizontal branch drain and 6 inches
above any insulation material and within 15 degrees of
vertical. Every structure in which plumbing is installed
shall have at least one primary stack vent. The stack
vent should run as directly as possible from the
building drain through to the open air.
Remove protective orange rubber sleeve after
installation.
Sure-Vent
®
AAV are intended for installation in the
confines of a structure, cannot be exposed to outside
elements and are intended for use between -40° F and
150° F. AAVs must be accessible for inspection and
service.
