• The Introduction Installation Course
• for the
• STUDOR Mini-Vent?
• Air Admittance Valve (AAV)

2
The Course should at its completion enable the
participants to 1. correctly identify the
components of the Mini-Vent Air Admittance Valve
(AAV) and 2. correctly install a Mini-Vent AAV
The Assessment will be via a written Question
Answer Sheet at the end of the course (Participa
nts are advised to make note of items marked with
a )
3
The STUDOR Mini-Vent

• A device that allows venting of sanitary
  fixtures (toilets, basins, sinks, baths, etc)
  without the need to extend vent piping through
  walls or roofs to outside atmosphere

4
The STUDOR Mini-Vent

• Is guaranteed for the life of the plumbing system
  to which it is attached!
• Every Mini-Vent has been tested twice before
  dispatch!

The STUDOR Mini-Vent
Mini-Vent
Now fixtures such as sinks, basins, baths,
laundry tubs , etc can all be vented inside
cupboards, vanity units, under floors and
counters without making unnecessary holes
through walls and roofs
6
Important Notes
1. Always make sure there is at least one open
vent on the plumbing line or system that the
vent is to be attached to
2. Do not remove the Mini-Vent from its
packaging until ready to install This way, the
chance of dirt , dust or grit getting into the
Mini-Vent is kept to a minimum
3. Never install a Mini-Vent where the air is
contaminated with solvents, e.g. a spray booth
7
Important Notes
4. Always ensure when installing any AAV that
it is an approved product and has both approval
and airflow capacity (l/s) clearly marked on the
body of the valve or packaging
On the top of the Mini-Vent are the relevant
Australian Standards Marking

Installation

• The Mini-Vent as supplied can be installed on 3
  different sizes of PVC DWV pipes
• 40mm to suit basins and baths in Australia
• 50mm to suit sinks, laundry tubs etc
• 32mm Older plumbing systems in Australia
  and basins etc in New Zealand
• The Mini-Vent can be installed up 1000mm
  (1 metre) below the rim of the fixture it is
  venting (i.e. the flood level)

to the top flange of the adapter.
NOTE Gluing is not required nor recommended!
12
Installation

• 3 RULES FOR INSTALLATION
• Always install the Mini-Vent vertically to the
  waste pipe
• Always install in an accessible location with
  adequate clearance around the Mini-Vent
• Always ensure at least 100mm of vertical pipe
  between the Mini-Vent and the pipe it is venting

At least 100mm
If all the above is correct, install fitting
(with Mini-Vent attached) to waste pipe as per
normal
13
Installation
Maximum of 1000mm (1 metre)
At least 100mm
A 45 degree junction with a 45 degree M F bend
may also be used
14
Installation
At least 100mm
No connection within 75mm of the trap
Between 300-1500mm maximum horizontal distance
from the trap
15
Installation

• To attach to a 40mm DWV pipe, discard the adapter
  
• A standard DWV female adapter is now used and
  screwed onto the male threaded Mini-Vent using an
  approved thread sealant (Teflon tape or similar).
  Hand Tighten Only. This is then attached to the
  discharge pipe
• (If required to be attached to a 65mm DWV pipe or
  larger, simply reduce the pipe to 50mm and then
  install as previously using the adapter)
• NOTE
• If the Mini-Vent is to be installed within a
  wall cavity, a mesh screen or grill must also be
  installed next to or as near as practical to the
  valve to ensure adequate air flow and access

100mm
16
Installation

• If installing in an outside or inside area,
  where there is likely to be extreme temperatures
  (below 0 degrees Celsius), place the top of the
  polystyrene packaging over the Mini-Vent
  to insulate it after installation

17
Installation
It is important to note that it is the capacity
of the valve, not its apparent pipe size that
allows it to be fitted to pipes up to 100mm
DWV The Mini-Vent has the capacity to vent
up to 10 complete fixtures (toilets, baths,
basins, etc)
Here, through the use of an adapter, the valve is
attached to 50mm hard drawn copper tube
Through a combination of other readily
available adapters the adapter included, the
Mini-Vent can be used on many other materials
and sizes of pipes
18
Installation

• Mini-Vents can also be used for venting groups of
  fixtures such as washrooms, toilet blocks etc
• This is called Group Venting
• The Mini-Vent has the capacity to vent
• 10 complete fixtures or 60 Fixture Units
• - 1 WC (toilet pan cistern) 4 Fixture
  Units
• - 1 Basin 1 Fixture Unit

Group Venting
This plumbing ventilation test rig, the biggest
in the world, was built by students and staff at
Gymea TAFE in Sydney, to prove AAVs were equal
to or better than Open Air Venting for groups
of fixtures
This entire rig was vented by just 2 Mini-Vents
20
Installation(Group Venting)
These 50mm vent pipes would be positioned on
the common or fixture discharge pipe where
previously a complete return to the main stack
would begin

• Simply install the Mini-Vent as previously
  instructed into a 50mm vent pipe when coming off
  a 100mm DWV common discharge pipe or upstream
  fixture. (But only rising a minimum of 100mm)

Standards AS/NZS 3500.2.2
22
Summary

• Weve learned that approved AAVs can be used to
  vent both single and groups of fixtures as well
  as how to install them in those situations
• Your Instructor will now hand out a Q A sheet
  for you to complete.
• GOOD LUCK!
