Notes on vent assembly
No silicone is used on the vent poly-
carbonate.
1. Fit either 201 or an autovent, if you
purchased one (see picture below), to
551 using the bracket & screws sup-
plied. Fig 3/8
2. Fit the vent sides 531 to the vent
hinge 541.
3. Slide in b7 (correct side to sun) and
attach 551 to the sides 531
4. Repeat the procedure for the other
vents.
5. Slide in the vents before you glaze
the greenhouse. Fig 4
6. Before you slide in a vent, slide in
one p3/a4. One of these needs to be
positioned on both sides of a vent to
stop it sliding sideways. Fig 6, 7
7. When the vent is in position and
opens and shuts nip up a4 so p3 re-
mains in position. Do this before you
glaze the roof otherwise you will not
be able to tighten a4 later.

The autovent fitted with 6mm bolts
before

den by polycarbonate.
