Roof Vent Installation
16
Now fit your autovents to the
slam rail and to the bottom of
the roof vents, diagram 87. Use
19mm screws to secure the top
arm of the autovent to the roof
vent, do this with the roof vent in
the closed position so that you
get the bracket in the correct
position.
Adjust the position of the lower
arm on the slam rail until the
arms of the autovent are parallel
with the roof as possible, then fix
with 25mm screws.
NB. Disregard any fitting
instructions in the autovent box
and any extra plates or screws as
these are for other greenhouses.
However you should keep the
leaflet as the operating
instructions are on there.
