INSTALLATION, OPERATING, AND MAINTENANCE INSTRUCTIONS
Dear customer, thank you for having chosen a weka product.
Please read these instructions carefully, so as to avoid incorrect
installation or damage to the product.
IMPORTANT: Please check the consignment against the pack list to ensure
that your weka product has arrived safely and with all components included.
Do keep the pack list together with your receipt until the warranty period has
expired, as it enables you to identify parts.
This makes it easier for us to deal with any queries or complaints you might
have.
Please note that item numbers in the pack list do not correspond to the item
number in this document.
If you sell the product, please hand the installation instructions, the pack
list, and any other relevant documents over to the new owner.
These instructions and our products are subject to technical changes without
prior notice. Your product might differ slightly from that shown in the
illustrations.
Safety information
Foundation
The ground under the weka – product or patio roof must be level and firm.
If you wish to install your weka product near slopes or on top of a basement,
please consult a local builder for advice.
Risk of collapse!
Space requirements
The space required for your weka product depends on its size. As the product
should be accessible from all sides for regular inspection, keep a clearance
of approx. 1.0 to 1.5 m around the product.
Safety instructions and warnings
To prevent accidents during assembly and installation, keep children away from
the site.
Children under the age of 14 must at all times keep a distance of a minimum of
3 m from the installation site.
Observe all applicable accident prevention regulations.
For more information, please contact your builder.
To access the roof, always use load-distributing planks.
If you need to carry out work on the roof, use proper equipment (ladders,
scaffolding, fall arresters) as required under the
applicable accident prevention regulations.
For detailed instructions, contact your local builder or safety authority.
Always work in teams of at least two people!
For the packing of the timber elements and installation, we strongly recommend
that you wear safety footwear and protective gloves. When drilling and cutting
timber, always wear safety goggles.
Unless specified otherwise in the product data sheet or in static strength
calculations, the roof must be cleared in the event of a snow load of
0.68kN/m², which corresponds to approx. 34 cm of snow.
Instructions for installation and use
Transport and storage
The product is shipped on pallets.
After unpacking and checking the consignment according to the pack list, store
the components as follows:
Protect untreated timber against
Consequences of incorrect storage:
– Cracks
– Warping and buckling
– Rot and mold growth
Store the timber so that it is protected agains the elements and ensure
adequate ventilation!
Timber is a natural product. Differences in color, knotholes and minor cracks
are normal and do not impair the strength of the elements.
Extreme weather conditions, such as prolonged hot periods, can cause cracks in
the timber caused by shrinkage. These have however no negative effect on the
quality of the product but are a natural phenomenon. In many cases, these
cracks close again when the weather changes. Shrinkage cracks that are in the
direction of the grain of the timber have no effect on the strength of the
material.
Packaging
Do not dispose of the packaging through normal household waste! To protect the
environment, separate the paper, cardboard, and plastic packaging and dispose
of these materials through recycling.
Wood protection
The product is made from untreated timber. The material must therefore be
regularly treated with wood protection. For effective wood protection
treatment, please consult a specialist dealer.
The responsibility for proper wood protection lies with the customer.
If the timber is not properly protected, the warranty shall be voided.
Please observe the relevant clauses in our warranty terms and conditions.
If you wish to have your product installed by a weka installation team, ensure
that all wood preservation work is completed prior to the arrival of the team.
To be observed prior to installation!
Before erecting the construction, contact the local planning authorities to
find out whether you need planning permission for your carport on the patio
roof.
Check whether the foundation contains power cables or water pipes and locate
them.
Preparation
For correct installation, the proper embedding of the H-shaped post anchors in
the concrete foundation is indispensable. The post anchors are available as
accessories from weka.
The foundation plan is available from your specialist dealer!
The required roof pitch of a minimum of 1% (sloping towards the back of the
construction) is produced by adjusting the height of the post anchors.
Alternatively, shorten the posts accordingly.
After leveling the ground, measure the foundation (height, width, length) and
prepare it for installation.
To facilitate the exact positioning and alignment of the anchors, mark the
post positions on the lath and secure the anchors with screw clamps to the
lath.
Then position the anchors in the holes in the foundation, keeping a minimum
distance of 2 cm between the upper edge of the foundation and the upper brace.
Fill the holes with B25 concrete and let the foundation cure for a minimum of
3 days.
Where timber elements are placed directly on the foundation (e.g. rear walls,
equipment rooms, etc.), install a damping course (e.g. roofing felt) between
the foundation and the timber to prevent rising dampness.
The damp-proofing material is not included in the scope of supply.
To prevent wind damage, secure the floor joists and the vertical posts to the
foundation, using concrete anchors or steel brackets and heavy-duty screw
anchors. The anchoring materials are not included in the scope of delivery.
Patio roofs
Depending on the wall construction of the main building, choose a suitable
method to secure the base or coupling stringer to the wall. This construction
must be made with fixtures that are suitable as regards the static strength
requirements and the wall construction (see technical data of fixtures).
Permissible V=1.77kN/m. The fixtures to secure the timber elements to the wall
of the existing building are not included in the scope of delivery.
To be observed during installation!
For the installation of your weka product, you must work in teams of a minimum
of 2 people.
All screw connections must be pre-drilled to prevent damage to the timber
elements!
This symbol in the instruction document reminds you to pre-drill:
To ensure perpendicularity, measure the diagonals and correct the position until the measured values are the same.
Roof panels
Prior to installation, store the panels under a roof or keep them covered so
that they are protected from direct sunlight!
White foil has proven particularly suitable for this purpose. If several
panels are stacked one on top of the other, they might become deformed or
discolored due to excess heat.
The panels must be installed at a temperature between +5°C and 30°C.
To ensure that the roof is tight, seal the panels with silicon (not included
in the scope of delivery).
To secure the roof panels, pre-drill them with a 10 mm drill!
With two-colored roof panels, the dark side must be the bottom side.
Do not fully tighten the screws as the panels need to settle.
Important: Do not install a false floor or thermal insulation under the roof
panels, as this would impair proper ventilation!
To prevent heat build-up under transparent roof panels, paint the upper side
of the stringers with white dispersion or clad them in aluminum foil (not
included in the scope of delivery). Heat build-up can cause cracks in the
panels.
IMPORTANT! When installing additional partition walls, storage rooms, or
wall coverings at a later stage, always ensure that air circulation under the
roof panels is not in any way restricted, as this could result in heat build-
up and damage to the roof panels.
Above all walls, keep a gap of a minimum of 20 cm to the wall panels.
Roof boarding
Where the roof is clad with tongued and grooved boards, do not push the boards
together too tightly, as the boards will swell slightly when exposed to
moisture,
The roofing felt supplied with your product provides some protection against
the elements but is not suitable as a permanent roof cover. To make your
construction weatherproof, you must install a second layer (e.g. bitumen felt
or shingles).
Otherwise, your weka product will be damaged over time.
Note
Regularly check all screws and re-tighten them, if necessary. This product
consists mainly of solid timber elements. As timber is a natural product, it
might shrink, so screw connections become loose.
Tools
The following tools are required on-site prior to installation.
