Installing roof cowl

  1. Attach provided grooved sealing strips (1.) to the sides and ridge.
  2. Also attach grooved sealing strips to the upper edge of the opening (2.).

This sealing prevents the drifting snow, driving rain, leaves and small animals from penetrating between the roof tiles and roof covering frame.

  1. Determine the distance between the roof covering frame and the centre of the fastening lug (*).
  3. Place the roof cowl and align the front side plumb and level.
  4. Draw on screw position. To do this, apply the previously determined dimension to the roof cowl.

Check that the roof duct sleeve has the required projection of 1 cm.

  1. Fasten the roof cowl on both sides with the supplied stainless steel self-tapping screws.

Before screwing on, check that the front is aligned vertically. When installed correctly, the roof duct sleeve has a projection of 1 cm.
