Roof Assembly
With help position the lower roof frame
assembly onto the building (diagram

See diagrams 44 and 45 for the fixing
down of the roof bars to the sides
making sure they are pulled tight into
the side glazing bars leaving no gap.
When in position drill vertically down in
the location shown in diagrams 45 and

Work your way around the building
until all roof bars are fixed.
