Installation

1. Lay slates to the required position. Cut the slate directly below the ventilator so it does not protrude past the slate batten. Cut a 280mm wide gap. Ensure position is not above rafter. Fold underlay back and pin to batten above.
2. Secure an additional support batten above cut batten—not required if slates are 400mm or less.
3. Position the vent central on the slates below and level with adjacent slates. Nail vent to support batten.
4. Cut two slates to fit either side of the ventilator. Add a hole to each slate piece as shown ensuring that it is twice fixed to the batten— appropriate slate hooks or dics rivets may also be used. Continue slating the course.
5. Lay next course of slate cutting the slate directly above the vent grille by an appropriate amount. Inspect the junction and security of the vent unit and adjacent slating before laying further course.
