10.4 Installing the collectors above each other
(installation height up to 20 m on tiled roof)
The following items are to be provided on site:
- For the lower row of collectors, materials in accordance with
chapter 10.3.2 are required.
- The upper row of collectors requires three additional roof
battens with the thickness of the existing roof battens and
the length of the collector array, plus 12 zinc-plated nails (1.5
x 20).
- Each collector in the upper row of collectors requires two
zinc-plated nails (1.5 x 20).
When installing collectors above each other, intermediate flashing
SOL AZ is required. Fit this at the transition point between lower
and upper collector.

f
Secure the lead flashing on to the two additionally installed
battens for the upper row of collectors. The lead flashing
should overlap the battens and the already fitted collectors
(lower row of collectors) by 100 mm.
f
Install the upper row of collectors in the same way as the
lower row. Start again with the right-hand collector array
end strip.
f
Fit the centre side flashing and the cover holder with the col-
lector on the battens. For this, use the six fixing points at the
upper end of the collector of the lower row of collectors. The
side flashing is only to be fitted once on the left and once on
the right of the collector array, not on each collector.
