Installation manualApexIn most cases, the apex is supplied in one piece (attention: in some house options, the apex can compriseseveral parts! In this case, these parts will have to be screwed together prior to other actions). Having installedthe last wall logs, place the apex on the front and back walls and attach them with screws.The apexes have indents for the rafters. The rafters also have the corresponding indents, ensuring that theroof is placed firmly and in the right place.Now place the rafters in thecorresponding indents in theapexes.Make sure that the upper wall log,apexes and rafters are level. Havingfitted the rafters, screw them ontothe apex from above.Installation of rafters:ATTENTION: If the wall logs are not properly pressed on top of one another without gaps, the upper wall logmay not be on the same level with the apexes. In this case you should tap the wall logs downwards asnecessary or plane the apex or sidewall log somewhat lower.RoofBefore installing the roof boards, make sure that the house is completely level. Use the water-level tocheck all walls.ATTENTION: When placing the roof, use a stable ladder. Do not step on the roof as the structure issuitable to sustain only an even load (snow, wind, etc.), and not a point load!Begin the installation of the roof boards from the front edge of the roof. Tap the boards lightly andattach them from above and below with nails to the rafters and upper wall log.ATTENTION: Do not press the roof boards together too densely and you will avoid moisture-causingbulging! Leave an interval of about 1 mm between the boards to allow for swelling. During the whole process of installing the roof boards, make sure that their crest rafters coincideand the eave sides of the boards extend at a uniform distance. Verify this with a rope or the lateraleave lath that you may install for verification purposes. The roof boards must be even with the rafter ends in front and behind. If necessary, saw both lastroof boards so narrow that they are even with the rafter ends.
