AUSTRALIA Presents

The Introduction & Installation Course for the STUDOR

®

Mini-Vent



Air Admittance Valve (AAV)

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 (Participants are advised to make note of items marked with a ‘*’)

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

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

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

Important Notes

*4. Always ensure when installing that it is an approved product and has both approval

and

clearly marked on the body of the valve or packaging

any

AAV airflow capacity (l/s) 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)

STUDOR Mini-Vent With adapter 40mm BSP male thread Adapter: Top Flange 32mm DWV push-fit over pipe Push-fit into 50mm DWV coupling of fitting socket with adapter

Installation

Recommended prior to installing the fitting 1 Mini-Vent as supplied with adapter fitted 50mm DWV coupling or fitting socket 2 Whilst applying even pressure, simply push the Mini-Vent into the coupling or fitting socket up to the top flange of the adapter.

3 Completed NOTE: Gluing is not required nor recommended!

Installation

* At least 100mm * 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 If all the above is correct, install fitting (with Mini-Vent attached) to waste pipe as per normal

Installation

* Maximum of 1000mm (1 metre) *At least 100mm A 45 degree junction with a 45 degree M & F bend may also be used

Installation

No connection within 75mm of the trap Between 300-1500mm maximum horizontal distance from the trap *At least 100mm

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

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

Installation

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 It is important to note that it is the capacity valve, of the not its apparent pipe size that allows it to be fitted to pipes up to 100mm DWV *The Mini-Vent has the capacity vent up to to 10 complete fixtures (toilets, baths, basins, etc)

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

Installation (Group Venting)

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) * 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

Group Venting Common Discharge pipes * Taken from Australian National Standards AS/NZS 3500.2.2

Summary

•

W e’ve 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!
