Main Building With Extension Assembly

6. You now need to have the rear gable in place (remember the rear gable has to go the right way around).
Once the rear gable is in place the extension ridge can be attached (Image E). Fit this in exactly the same way
as the main building’s ridge, making sure the ridge sits on top of the ridge extension bracket. Remember it is
easier to attach 10mm bolts to all the holes before you fix the ridge in place.
7. You now need to attach the extension sides. Simply attach the gutters and cills to the extension brackets
using 10mm bolts (Image F). Stand on the inside of the greenhouse with the gutter facing away from you,
insert the gutter bar into the gap between the corner bars so that the inside flanges which form the angle of
roof and side line up with the bolts in the corner bars. Loosen the nuts holding the 2 bolts previously in-
serted into the corner bars and slide them into the slotted holes in the flanges of the gutter, then tighten.
Repeat this with the bottom bolt and attach to the side cill. Repeat on the other corner.
You will see that the holes are in pairs. When you are building the right hand side assembly you use all the
right hand holes in the pairs. So when you build the left hand side assembly you will use all the left hand
holes in the pairs.
8. The roof bars can now be attached to the structure. Attach the bars first at the ridge, prior to tightening
ensure that the roof bar is pushed up hard against the ridge. Do not attach the bottom of the bars to the
eave until all the roof bars are bolted to the ridge.
Very Important
: Bolts will need to be slid into each roof bar for the ridge brace. One more bolt is needed to
attach the eave 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. If you haven’t already done so you need to decide
now where your roof vents are going to be positioned so that you can work out the number of bolts in each
bar.
9. Now attach the bottom of the roof bars to the gutter bar using a 10mm bolt. Slot the bolt into the holes
in the upper flange (Diagram G-3). Start with the middle bars either side of the ridge.
10. 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 downward dip in the ridge.
11. You can now attach the braces (751) which bolt into the apex of the roof. Use the top bolt out of those
you have slid into each roof bar (Diagram G-1). Next you can attach the eave braces (753) between the roof
and the sides using the bottom bolt in your roof bar channels and the extra bolt you slid into the side sec-
tions earlier on (Diagram G-3) The remaining bolt in the roof bar is used to attach the vent slam rail in your
predetermined locations (note: the slam rails should be attached after the greenhouse has been glazed).
12. Once the frame has been constructed you can return to the Titan 79 instruction book and continue with
the assembly.
