Installation Instructions

  • Before installing the louvre fittings, make sure the frame is square and true throughout. Failure to observe this fundamental instruction will cause the louvres to be stiff in operation and could result in air and water leakage.

  • When screwing the louvre mullions to the side frame ensure that they are exactly parallel and opposite each other. Providing the frame is plumb in all directions this may be done easily by scribing a guide line down either jamb at equal distance from the outer face.

  • Ease back the glass retaining clips and then insert the glass blade. When this is fully home the clip must be bent over the top edge to retain the blade in its correct position.

  • The louvre must be in the locked position when fitting the sillboard at the bottom and the cover bead at the top. These should be brought up to but NOT pushing against the glass. This will ensure the weather-proof seal between the blades is maintained. This is most important as most complaints concerning faulty operation of the louvre are due to incorrect positioning of the sill-board or cover bead forcing against the glass preventing the blades sealing correctly.
