Important:
If you have ordered an impregnation, it is oil-based, so the top coat should also be
oil-based.
GreenLine Roll Observatories are now STANDARD with SLIDING DOORS, if
you want a hinged door please order specifically.
Please note: 10 planks are stacked on top of each other on the back.
First there is a starter board, then 9 wall boards with rounded heads on both sides.
- The last one has a flat top. The side walls each consist of 13 planks (including
starter). They differ from the rear wall in that only one end of the plank is rounded.
If you make sure that the holes in the boards always point towards each other
during installation, it will be easier for you to install the vertical rails from the back
wall later.
There are two support beams with holes going through just before the notches
(holes larger on the outside than inside). This is plank number 11.
You have a total of four guide rails: those pointing backwards, each with a built-in
pulley.
If you have ordered manual operation of the roof and shutters, two additional
rollers are installed at the end of the rear guide rail to accommodate a set of
counterweights.
(Tip: place a wooden board on the base frame, put the weight on it and attach it.)
After installing the weights, the two plywood panels are screwed on. They cover the
weights.
The best way to secure the roof and shutters is to get some window hooks or lock
the foils at your local hardware store to secure the shutter.
Storm protection / severe weather kit:
We offer an optional wind protection kit. Either pre-installed, or as a quick DIY
upgrade.

Assembly of the base frame:
Put the four painted squared timbers (4x6 cm) together to form a rectangular frame.
At this point it would be good to put a bitumen strip or something similar under the
base frame (moisture barrier). Now screw the corners together. The frame should be
centered on the concrete foundation. Before this frame is anchored to the foundation,
the diagonal must be checked in any case, as well as its straight alignment.
The frame is anchored with eight M10 concrete anchors (not included). It is also good
to countersink these anchorsin the base frame so they are not in the way of subsequent
assembly steps. After fixing the basic frame, you can start with the so-called starter
planks.
(Planks B1, D1)
6
FIRST STEPS ....
Now insert the wall planks one after the other.
(Please start with the smaller "starter" planks B1 and D1, then planks A1, C1 and E1)

Structure of the walls:
Place the first layer of wall planks (starter planks) and the first layer of log planks
on the base frame. Now screw the starter with the brackets on the frame (5x30).
Make sure that the wall planks lie evenly inside one another.
Walls & Door
General remark:
In the rear area, 11 logs are laid, one on
top of the other.
A starter plank and 10 logs with heads
rounded on both sides, here is also a log
that has no key at the top. The side walls
each consist of 13 logs (incl. starter),
they differ from the rear wall planks in
that only one end of the log is rounded.
The square ends point to the rear.
Now complete the walls by stacking the
remaining planks according to the photos.
Please check the walls regularly with a
spirit level!
Do not use force, if one or the other
planks does not immediately locks
into the next one.
Try to find the cause and fix it.

BUILDING THE WALLS
We color-coded the diverse building
components to more clearly show
what belongs where.
TYPES OF DOORS
Depending on what exactly you order,
you will either have a hinging door, or
a sliding door.
All standard GreenLine
observatories come with a
SLIDING DOOR.
Other doors are only on demand.
This sequence gives a good impression of all
the phases of your construction.

Guide bar
You have a total of four beams: two
sections with pulleys and pre-mounted
rails, which point to the rear wall, and two
more beams rails also pre-installed, but
without pulleys. These belong in the front
area and are held up by the two vertical
support beams.
Fasten the two left beam segments to form
a guide beam. The same for the right
beam segments. For this purpose, three
screws of the size 8x80 for each side are
included.
Place the rear beam elements on the left
and right (using the key and groove of the
wall planks) so that the outer edge of the
rear wall is flush with the timber of the
guide beam.
10
Roof & Guide Beams
Support and guide beams
Now place the two support beams in the
specified positions under the guide beams
and screw them tightly through the bar
from above. (Washer and M16 screw).
Fasten the cross beam between the two
guide beams. They are screwed with four
screws.
Always construct your guide beam / cross
beam and support beams with a spirit
level.
Also check the straight and parallel
alignment of the two guide beams.
Verification of all horizontal and vertical
dimensions is very important for smootly
running roof section.
We recommend size M8 concrete anchors
to fix the columns to the ground; available
in your local hardware store.

GreenLine MINI:
Diagonal bracing is done by means of steel cables.
Attach both steel cables for the diagonal bracing of the
guide beams. The ring fixtures are screwed into the beam,
then attach the pre installed terminators of the steel cables.
Both cables should be tense, but not overstretched.
11
Diagonal bracing
GreenLine MEDIUM & BIG:
In these bigger observatories diagonal bracing is done
with two rigid cross beams.
The two cross beams are fixed between the guide beams
and the cross bar with two screws each (8x140)

How to mount the corner support
beams in your
GreenLine MINI:
Assemble the rear inner corner support beams
(labeled B / C, C / D) as follows: at the bottom
with a screw (8 x 80) in the downward facing stub.
Then fix it by a screw (8x180) from above through
the guide bar. The corner beam should fit "snug" in
the corner, if necessary use a clamp, to help it in.
The last action is to drive a screw (8x80) from the
outside through plank (B and D) #11. (you may
need add more)
A screw (8x80) is driven-in from the outside of the
starter plank on the two front corner bars (door
area) that are also on the inside. Then again from
above, through the guide bar (8x180). Here, too, a
screw is driven-in from the outside in plank #11.
The left bar is also the door post. This receives
three screws (5x60), ascending from bottom to
top, in the pre-drilled holes. Here, too, using one
or more clamps are very helpful.
12
Corner support beams
How to install the corner support
beams in your
GreenLine Medium and
GreenLine BIG:
Mount the corner support beams on the inside
(labeled A / B, B / C, C / D, D / E) as follows: at
the bottom with two screws (8 x 80) in the
downward facing stub. Then fix it by a screw
(12x200) from above through the guide beams.
The corner beam should fit "snug" in the corner, if
necessary use a clamp, to help it in.
The last action is to drive a screw (8x80) from the
outside through the planks (B and D) #11.
The first plank right next to the entrance on the
left is the door post, which is fastened at the
bottom with two screws (8x80). Then three times
(8x100), ascending from bottom to top, in the pre-
drilled holes.

Installation of the rails
That was all quite easy, wasn't it?
If everything went well, all the walls, the guide
beams, as well as the support columns are now in
place.
Your kit contains several rail elements. They are
marked either "roof" or "shutter".
Please attach the rails to the
guide beams, using the existing
holes (long rail at the back, short
rail at the front).
In spite of everything, make sure
that all rail segments follow a
straight line.
Take care not to cause any
dents or cuts in the rails. This
largely determines how well
your roof will later run over
both rails!

By the way ....
AGreenLine roll-off observatory is a fine thing. Did you know that the famous English astronomer Sir
Patrick Moore always had wooden observatories at his house? Many of his publications and books, which
inspired so many people to observe the heavens, were written there. The British television series "The
Sky at Night" hosted by Patrick Moore, showed time and again his green roll-off observatory in the
garden.
So, you are in good company when you have decided for one of our GreenLine roll-off
observatories .......

Roof assembly
ATTENTION:The roof roller system runs very smooth and easy. Do NOT forget to use
clamps to keep the roof section in place while you work at it!
Attach all rafters pairs to the two roller beams. Use the supplied 8x100 Spax The positions ar
indicated on the roller beam.
The rafters pairs with the front gable is for the entrance area, the pair with the smaller
triangular plates on the rafter heads should be at the backside of the observatory.
All positions are marked for this purpose. Note the outer cover of both the guide beams are pre-
installed in our factory to safe you time.
Remove the clamps to allow the roof to properly settle on the rails. Then lock it back with the
clamps so you can proceed with the roof construction
Make sure to use the ENTIRE contact surface when you attach the rafter pairs to the roller
beam. (See detail). The notches in the rafter pairs must fit perfectly around the edges of the
roller beam! Check this! Then using the supplied screw screw everything tightly together.
After successfully installing the rafters pairs, remove all clamps that secured the roller beams
and the roof during the assembly work. This is as good a time as any, to check if the roof
moves smoothly. If it goes well, secure the roof again with at least two clamps.
Roof and roller beams
Place both trolleys / sleepers with their rollers on the guide rails. Use at least two large clamps
to hold them in place after aligning them perpendicular to the rails. This is important.
Positioning tip: a piece of wood approx. 15mm fits outside between the guide bar and the
trolley. And the beginning of the trolley should be at the front gable.
The guide roller bar with the rack must be on the left (for Medium and Big, for Mini the rack is
on the right). Position both guide beams so that the steel cables will later point away from the
observatory. You can now start assembling and installing the rafters on the guide rollers and
attach all the connecting plates and all other components as shown in the drawing.

Please take care that the planks that cover the
sideward slits in the roof do fit smugly between the
rafters, to keep out insects, stray rain and drift
snow.

Assembly of verge boards
Screw the verge boards to the eaves boards so that the
underside is flush with the lower edge. This means that
they are approx. 2 cm above the roof covers plates
How to cover and protect your roof
The roof should be covered with asphalt, tar paper,
shindles, or a high quality PVS or ABS trapezoid roof
covering.
A provisional roof felt-cover is part of the delivery, but this
is NOT a substitute for a proper roof covering. You can see
this as temporary protection (max. three months) until
bitumen sheeting, trapezoid cover sheets or the like MUST
come on top of it.
If available: Roof panels / trapezoidal panels made of PVC
and with ridge cover (holes must be pre-drilled!) must
fastened with flat headed screws.
Make sure to seal the trapezoidal sheets on the downward-
facing side with silicone or SikaFlex.
18
The Roof
Assembly of the roof boards
Please note:
Rafters, edges, eaves and gable
boards must be nicely parallel! No slits
or open seams!
Always start attaching the roof plates
in the middle and then work outwards!
Due to the construction of roof frame,
there should be no seams, or slits in
the ridge area!
Check that there is roof overhang
before you start fixing everything in
earnest!

Movable rear wall (shutter):
Attach the two vertical shutter rails
with the enclosed screws, 28pcs.
(5x30).
Attach the guide rails from the top of
the wall, vertically (two photos's
below). The rails should be fixed
parallel to the rear wall. You must
determine the exact distance from
the rear wall by placing the roof in
the "closed" position. The two
triangular closing boards (roof, left &
right) should later coincide with the
shutter board.
With two people insert the shutter in
the rails from above. Place a short
square piece of wood under the
shutter, to keep it in place.
Make sure that all rollers engage in
the rails. You should check the gap
between the shutter and the outer
logs. If necessary, you can adjust by
changing roller distance. The brushes
attached to the side are only clamped
under the rollers.
