3 Prepare Installation Field
To warrant permanence of the installation, various prereq-
uisites have to be fulfilled:
●
A waterproof and diffusion reducing foil with at least 24
mm counter-lathing must be present to assure proper
ventilation If proper backside ventilation cannot be
provided via ridge and eaves, a venting tile must be in-
stalled, approx 90 cm above and below the collector
field (see also figure 8, lower part)
●
Keep a distance of at least 1m between collectors and
roof components or extensions like vents, turrets, chim-
neys or roof windows that emit humid air Otherwise ad-
ditional humidity might enter the collector vents at the
collector frame
●
There should be at least 2 rows of roof tiles above and
below the collector field
●
The roof tile row above the collector should extend for
at least 100 mm over the upper flashing sheets If re-
quired, the roof tiles have to be shortened
●
For best results properly utilize the flexible space below
the collector (distance to lower tile row between 60 and
130 mm)
Figure 7 Dimensions of installation field and positions of installation laths in mm. Choose lath thickness based upon existing laths.
Additionally required laths are coloured grey (5 pieces); lath length = A (width of installation field).
Installation field width = n x collector width + n x 5 mm (distance betw. collectors) + 2 x 15 mm (distance from edge)
Leave the existing roof battens in place as supporting
construction, and affix the additional laths required for the
installation according to the dimensions given in figure 7
and 8
Ideally determine the width of the collector field in such a
way that on one side the spacing between collectors and
roofing is approx 15 mm On the other side cut tiles to fit
