Lower fitting, steel
Roofing tiles
Build a frame around the bottom fitting’s connecting
piece at the same height as the roofing. Return the
cornice and then the roofing. In some cases, it may be
necessary to cut roofing tiles.
Install the enclosed weatherstrip at the bottom edge
to prevent moisture being blown in.
Then place the lower fitting in position, centre over
the bottom fitting and screw into place.
Ensure that the roofing tiles and lower fitting are
clean. Glue the aluminium-reinforced rubber mem-
brane onto the top edge of the lower fitting, then
slide it in under the first row of roofing tiles. Press the
membrane onto the top of the roofing tile, then shape
the membrane so that it seals tightly over the entire
row of tiles.
Pay attention to runoff. Ensure that the rubber
membrane is shaped so that there can be no stand-
ing water. Take particular care at the transition
between roofing tiles and the lower fitting at the
upper edge.
Steel plate roof – extension plate
In the case of a steel plate roof, the lower fitting must
extend in under the next steel plate joint with a min-
imum overlap of 10 cm or up to the roof ridge. If this
is not satisfied, extension plates (accessories) must be
used.
Loosen the roof ridge plate.
Start by installing the enclosed weatherstrip at the
bottom edge of the lower fitting to prevent mois-
ture being blown in. Then place the lower fitting in
position, centre over the bottom fitting and screw into
place.
Then extend with plates if necessary from below, up
towards the roof ridge. Ensure that runoff takes place.
Reinstall the roof ridge plate over the lower fitting or
the extension plate.
