  1. Lay tiles in accordance with manufacturers recommendations up to where you wish to place venttile. Offer up vent tile to the fixed tiles and mark on the underlay the centre of the pipe spigot. (Picture 1)
  2. Mark horizontal and vertical cut lines onto the underlay, intersecting at the previously marked centre point. Cut along the marked cut lines with a craft knife. (Picture 2)
  3. Track the 2 upper wings of underlay to the underside of the batten above with 2 felt tacks.Fold down the 2 lower wings of underlay to allow flexi pipe to be inserted. (Picture 3)
  4. Slide felt weir under the batten directly above the opening, making sure it is centred over the opening. The upstand should rest against the top of the batten. (Picture 4)
  5. Mark where the left and right edges of the felt weir sit on the underlay. Cut horizontally between the 2 marked edges with a craft knife. (Picture 5) Insert felt weir into the opening,making sure the upstand rests against the batten as described in point 4.
  6. Insert the flexi pipe into the originally cut opening, ensuring underlay wings are not pushed back into the roof space. (Picture 6) Push remainder of the flexi pipe into the opening until the vent tile sits neatly on the tiles.
