Tile Ventilator
DecraVent tile vents are manufactured from UV stable PVC and are colour matched using the same stone granule finish as the Decra roofing system.
Soil and Mechanical Extract
The DecraVent tile vent can also be used as a weather-protected exit point for soil pipes or extractor fan ducts. Connection to 100mm diameter stacks or ductwork is by means of a separately available adaptor and flexible hose.
The vents offer an airflow resistance of 32.7 pascals at 100m3/hr flow rate. To comply with Part H of the Building Regulations and the Building Standards (Scotland) Regulations 1990, DecraVent Tile Vents used for soil stacks should be sited at least 900mm above any opening into the building within three metres. All connecting pipework should be insulated. |

Setting Out
For high level ventilation install vents at recommended centres on the second course down from the ridge or top edge.
For low level ventilation install vents at recommended centres on the second course above from the eaves.

Fixing
Positioning tile vents
The exact positioning of tile vents to achieve the ventilation requirements is determined by the module size of the respective roof covering. Additional staggering of roof vents may occasionally be necessary to prevent the underside of the vent fouling rafters or fire wall
Decra Classic, Elegance, Plus Tile, Decra Stratos and Parctile:
1. Locate the position of the Tile Vent extension pipe on the underlay.
2. Remove Tile Vent and cut underlay, folding flaps upwards and outwards.
3. Cut a 340mm horizontal slit about 100mm above the opening created. Place flat end of the Opening Protector into the slit and locate the upstand end above the opening in the underlay.
4. Fit Tile Vent following normal Decra tiling procedure.
5. Insert the extension spigot into the roof space, ensuring the three underlay flaps are facing upwards.
6. Fix the Tile Vent into position by overlapplng a standard Decra tile on either side. Nail through the nose of the tiles immediately adjacent to the Vent once the course below the Vent has been installed. Do not nail through the nose or upstand of the Vent.
If connecting to soil or mechanical extract:
7. Fit the DecraVent Pipe Adaptor. Then connect the Flexible Extension Hose from the Pipe Adaptor to the soil or mechanical extraction stack using jubilee clips provided. Ensure all pipework is insulated.
IMPORTANT NOTE
Do not use vents as exit terminals for hot combustion gases.
Decra Oberon Tile only:
Cut away small section of intermediate tile batten which fouls the underside tray of the Oberon Tile Vent, allowing Vent to seat properly on the battens.
1. Locate the position of the Tile Vent extension pipe on the underlay.
2. Remove Tile Vent and cut underlay, folding flaps upwards and outwards.
3. Cut a 340mm horizontal slit about 100mm above the opening created. Place flat end of the Opening Protector into the slit and locate the upstand end above the opening in the underlay.
4. Fit Tile Vent following normal Decra tiling procedure.
5. Insert the extension spigot into the roof space, ensuring the three underlay flaps are facing upwards.
6 (A). Fix left hand side of Vent
Overlap a standard Oberon Tile over the vent. Nail through the nose of the overlapping tiles immediately adjacent to the Vent after installation of the course below the Vent. Drive Decra fixing nails through the bottom downturned nose of the tile and through the intermediate step of the downturned nose of the tile into the face of the battens. Do not nail through the nose or upstand of the Vent.
6 (B). Fix right hand side of Vent
Overlap Vent over the top of the left hand side of a standard Oberon Tile. Nail through the two pre-formed nail holes in the Vent tile and through the nose of the standard Oberon Tile into the face of the battens. Do not form new holes in the Vent - use only the two nail holes provided.
If connecting to soil or mechanical extract:
7. Fit the DecraVent Pipe Adaptor. Then connect the Flexible Extension Hose from the Pipe Adaptor to the soil or mechanical extraction stack using jubilee clips provided. Ensure all pipework is insulated.
IMPORTANT NOTE
Do not use vents as exit terminals for hot combustion gases.
