SLOPING ROOF
ASSEMBLY INSTRUCTIONS
A suitable earth plant must be prepared by qualifi ed
staff according to standards in force before installation
of the panels.
The Extrafl ame PS AS1 collectors can be mounted on
the pitch of the roof facing south by simply removing
some tiles.
The collectors are mounted vertically and positioned
in arrays made up from 2 or more panels (see
“series/parallel connection layouts and panel arrays”
chapter).
All additional elements that are not envisioned in the
kit and supplied by the installer must be:
Perfectly insulated
Weather resistant (wind and water) and to the
penetration of humidity into the heat insulation
Resistant to UV rays
Resistant to the pecking of birds
type of roof and the climatic area where installation is carried out. The installation company is responsible
for respecting the standards in force and carrying out the job perfectly.
In the case of roofs with slopes less than 35°, particular attention must be paid to the currents that develop
at the ends and in the corners. Figure 5.2 supplies an indication of the lateral areas of the roof with slope
less than 35° where the panels must not be installed. The length a represents the smaller side of the roof
plan given by the length of the building plus the eaves, while b is the long side of the roof plan equal to the
length of the building plus the eaves. R is the lateral width on which the panels must not be installed.
For closed building, R must be greater than or equal to a/8.
The panels must also be positioned at a distance of at least 0.5 m from the ridge of the roof.
