Roof Vent Installation

Dia. 70
Take the vent frame that is ready
assembled and fix the vent hinge to one
end through the 4 pre drilled holes
using the 19mm screws, diagram 69
and 70. Once this is in place fix the
plastic vent filler (EV0323) also with a
19mm screw, its is important to make a
pilot hole before fixing the plastic filler
to prevent splitting.
Now take a 610mm x 469mm pane of
glass and locate this in the vent hinge.
Before lowering this down completely
slot the glass stops onto the open edge.

When in position you can fix the glass in
place with the vent capping (either cedar
or aluminium) using the 25mm screws,

aluminium capping system you will need
to insert the rubber seal before fixing it in
place.
