Installation Advice

- Use to ventilate pitched roofs, where the pitch of the roof is 15 degrees or more, and the roof void is attic or loft space.
- Do not use to ventilate pitched roofs where the pitch of the roof is less than 15 degrees, flat roofs or any roof where living accommodation is contained within the roof space.
- Space ventilators at 200mm centres.
- Take care to ensure the fixing holes are cut accurately with a diameter of between 69-70mm. If the holes are oversize, the ventilators will not fix securely.
- The ventilators should be a firm push fit into the fixing holes.
- Ventilation must be provided for the full length of the eaves and along both sides of the building to create a cross flow ventilation action.
