MAIN BUILDING ASSEMBLY
Very Important:
Bolts will need to be slid into each roof bar for the ridge cantilever, two more
bolts to attach the hanging basket rail, one more bolt is needed to attach the eave cantilever
bracing between the roof and the side. Please note: At this stage you will need to insert an extra
bolt into each bar either side of a vent opening. So you will have to decide now where your roof
vents are positioned so that you can work out the correct number of bolts in each bar.
8. Now attach the bottom of the roof bars to the gutter bar into the holes in the upper flange
(Diagram FF). Start with the middle bars either side of the ridge.
Before tightening the nuts that hold the roof bar to the eave you must ensure that the roof bar is
tight up against the small flange immediately above the gutter (key point). Failure to observe
this point and the previous one of keeping the roof bar tight up to the ridge could result in a slight
outward bow of the gutters and a slight downward dip to the ridge. Also try to make sure that no
glazing rubber extends from the rubber channels for a tighter neater finish.
9. At this point you will need to lift the structure onto a firm, level, and square (check internal
diagonal measurements are equal) footing or the greenhouse base if you haven't already done
so.
10. You can now attach the T-bar cantilevers (600) which bolt into the apex of the roof. Use the top
bolt out of those you have slid into each roof bar (Diagram GG).
11. Next you can attach the eave cantilevers (601) between the roof and the sides using the bottom
bolt in your roof bar channels and the extra bolt you slid into the side sections earlier on
(Diagram HH). The remaining 2 or 3 bolts in the roof bar should be above the eave bracings
and are used to attach the hanging basket rail and the vent slam rails in your predetermined
locations (note: both the slam rails and the hanging basket rail should be attached after the
greenhouse has been glazed).
