FloPlast AX110 External AAV

110mm push-fit

£24.99 + vat

Whilst AAVs have been around for many years their use until now has been limited to internal installation by local planning regulations.

However, improvements in technology, together with a new European standard for AAVs (EN12380), have resulted in the availability of valves that have been fully approved for external installation.

The FloPlast AX110 is the world’s first fully approved External AAV.

It eliminates the need for the installer to work above the roof line, thus making it easier to comply with "working at height" health and safety regulations.

The UK Building Regulations, Document H1, stipulates that any soil and vent pipe installed externally within three metres of any opening window, is required to terminate a minimum of 900mm above the window.

This new development allows a soil stack fitted with an external Air Admittance Valve to terminate within three metres of a window opening, at the same height as if it were installed internally i.e. a minimum of 200mm above the highest wet entry point to the soil vent pipe.

Approvals and Standards

1. Product is A1 approved in accordance with BS EN 12380 - it can be installed below the flood level of connected applicances.
2. Tested and approved for use in installations varying between -20° and +60°c (no insulation required).
3. CE marked to level 4, attestation of conformity in accordance with BS EN12380.
4. FloPlast Air Admittance Valves are kitemark licenced in accordance with BS EN 12380:2002 licence number KM 512474.
5. British Board of Agrément (BBA) approved 06/4343.

Installation

The FloPlast AX110 has been designed for push-fit installation directly into 110mm UK designated pipe with the use of an EDPM finned seal. Push-Fit connection means that it can be easily removed, as necessary, to provide a secondary rodding point.

Designed for use on discharge stacks up to 45 metres or 10 storeys high.

Airflow capacity = 43 litres/sec.

The AX110 must be installed in a vertical position a minimum of 200mm above the highest branch connection.

The BS EN 12380 A1 rating of the valve means that it can be located below the flood level of the appliances being vented.

NB. The AX110 should not be used when the discharge stack to which it is fitted provides the only ventilation to a septic tank or cesspool.

The product, which is supplied in three colours (Black, Grey and White) should be stored upright.

AX110 Maintenance Requirements

To ensure the continued performance of the valve, FloPlast recommend that annual maintenance of the opening and closing mechanism is carried out. To achieve this:

1. Firstly, remove the lid by unscrewing anticlockwise.
2. Remove the separate ring holding the rubber seal (poppet).
3. Inspect the seal faces on the body and the poppet to ensure that there is no environmental or insect ingress. If necessary, clean the sealing faces with a lint free cloth.
4. To reassemble, lightly lubricate the sealing faces on both the body and the poppet with a silicone lubricant (e.g. silicone grease SG100).
5. Place the poppet over the guide pins.
6. Once in place, rotate slightly to ensure even distribution of the silicone.
7. Replace the lid and screw clockwise to ensure that it is completely secure.
