The Nature of Wood
The wood provided for your garden building is softwood which has been kiln dried and is pressure treated for
protection against fungal decay and insect infestation. Wood is a natural product which may have knots, knot holes,
imperfections, cracks and warping.
Due to the inherent properties of wood we make no guarantees with regards to the above, nor will replace any
lengths of timber for any of the following reasons:
•Any timber that contains knots where they do not influence the structural stability of the product.
•Cosmetic appearances - colour variations e.g. caused by the structure or age of the product.
•Timber that has shakes, cracks or gaps that do not influence the structural strength of the product.
•Any timber that has been covered or buried underground.
•Twisted timber that can be installed.
•Queries arising from a neglectful manner of construction be in the foundation or erection of the product.
•Queries due to modifications by the owner causing timber to deform.
Any valid queries will be satisfied by the exchange or replacement of the defective parts only.
Your Gazebo has been designed with the self build in mind. However, it is important that the assembly
instructions are followed carefully.
Precautions:
•Always use working gloves.
•It is essential to have an assistant.
•All screw holes need to be pre-drilled using a 3mm drill bit (not provided) to avoid timber splitting.
The Gazebo is pressure treated so you will not need to treat it immediately or apply a preservative.
Pressure treatment does not mean that the timbers are waterproof, so you may wish to apply water repellent.
Water repellent can also be applied to timbers treated with a preservative.
Colour Transfer
This product has been pressure treated with wood preservative and a brown colour additive. Consideration should
be given to the propensity of the material to stain light colour adjacent surfaces, such as paving flags, render or
coated timber surfaces. We recommend contact between the timber and these surfaces is limited, and careful
consideration to storing the product prior to assembly should been taken in order to prevent such discolouration.

•Fully cover the roof boards with the plastic
waterproof membrane, overhanging the roof
boards by a minimum of 30mm.
•We suggest to fix it using a staple gun.
Waterproof membrane
•Place and fix the first row of felt over the top
of the waterproof membrane, overhanging the
roof by a minimum of 40-50mm and spacing
clout nails approximately 200mm apart.
•Trim off any excess at the end of the row,
reusing offcuts where possible.
•Lay a second layer of felt on top of the first
row. Ensure the second layer overlaps the first
by a minimum of 200mm.
•Trim off any excess at the end of the row,
reusing offcuts where possible.
•Continue to lay felt in rows, overlapping each
row by a minimum of 200mm until you have
reached the end of the roof.
•Where the felt meets the wall, locate
the mortar in between the bricks
directly above the canopy gazebo.
•Remove the mortar to a depth of
approximately 20mm for the whole
length of the canopy gazebo.
•Insert the lead flashing (not supplied)
into the mortar aperture and form the
lead to match the wall and roof
profile.
•Once you have formed the lead,
secure it into position by using fresh
mortar or silicone.
•When your felt is fully installed,
continue by fixing your fascia.

•Trim off any excess at the end of the row,
reusing offcuts where possible.
•Lay a second layer of shingles on top of the
first row. Rotate this layer of shingles by 180°
so that the slots are running downwards.
•Trim off any excess at the end of the row,
reusing offcuts where possible.
•Continue to lay shingles in rows offset and
overlapping each row until you have reached
the end of the roof.

•Screw the running outlet to the fascia, ensuring the
downpipe will be in line with your post (Fig.A).
•Fix the support brackets to the fascia using two screws per
bracket and ensuring spacing of 400-600mm between each
support bracket (Fig.B).
•Slot one piece of guttering into the gutter union and then fix
to the fascia with one screw, ensuring that there is 1
degree of fall towards the running outlet to allow the
guttering to drain.
•Connect the next gutter section to the second union and
click this assembly into the first union and screw to the
fascia (Fig.C).
•Continue adding sections of guttering to fit the length of
your canopy gazebo, repeating the previous steps and
finish off by connecting the stop end to the last section of
gutter, trimming the guttering to the correct length where
necessary.
•The stop end should finish approximately flush with the end
of the fascia (Fig.D).
•Join together sections of downpipe and elbow pieces to
desired length, finishing with a shoe piece (ignore this step
if installing a water butt).
•To install the water butt, connect the downpipe sections and
elbow pieces to the running outlet and position the water
butt below the downpipe, with the lid removed.
•Mark and trim the downpipe so it extends into the water
butt by approximately 150mm.
•Note - the hole in the water butt lid will need to be cut out
to match the diameter of the downpipe.
•Once all the guttering components have been positioned
correctly screw the downpipe brackets to the canopy
gazebo post (Fig.E).
