AmeriVent Round and Oval Gas Vent
Installation Instructions
Universal Adapters
The Universal Adapter (EUA-M and EUA-F) is available
in sizes 3-inch through 6-inch in both male and female
versions. The Universal Adapter may be used to
connect AmeriVent round Type B Gas Vent to other
manufacturers listed Type B Gas Vent as shown in
Table 3.
1. The Universal Adapter is installed, as shown in
Figure 15, by sliding the Adapter over the outside wall
of the other listed Type B Gas Vent. For the Male
Adapter, the inner wall goes inside the other Gas Vent,
while the inner wall for the Female Adapter goes
around the outside of the bottom end of the inner wall of
the other Gas Vent.
2. When the Universal Adapter is in place, tighten the
fastener securely.
3. The Universal Adapter is not intended to act as a
structural member, and the Vent installation should be
resupported.
Increasers
An Increaser (IX) is used to make a transition from a smaller
vent diameter to a larger vent diameter. The Increaser is
available in steps up to a maximum of four (4) sizes larger.
For example, a 4-inch diameter vent can be increased with a
single Increaser from 4-inch to 8-inch or 5-inch to 9-inch.
Tees and Wyes
Model E and R Tees (T) and Wyes (Y) are designed for
breeching or as connectors for vertical, sloped, or horizontal
systems. They can also be used to provide access for
inspection or drain fittings. Tees and Wyes must be isolated
from expansion forces by supporting as needed and with
Adjustable Length Sections. Any unused open end of the
Tee or Wye should be closed off with a Tee Cap (TC).
Reducing Tees (T) and Wyes (Y) are also available.
Elbows and Offsets
AmeriVent Type B Gas Vent Model E, sizes 3-inch through
6-inch, and Model R in sizes 7 and 8-inch, are available in
both a 45º and 90º fully adjustable offset. The 9-inch
through 14-inch Model R is only available in a 45º
adjustable elbow. The 16-inch and larger is available in 45º
nonadjustable elbow. See Tables 4 and 5 for relative
dimensions of offsets and combinations of offsets.
Whenever Model E or R Gas Vent Pipe is changed from a
vertical direction, the Vent system must be resupported
before and after the change in direction. The support
should provide rigid stability, both vertical and horizontally.
See Figure 16. Check with your local Building Officials to
make sure any alternative support method is acceptable.
