11.2 Vitosol-FM/-F flat-plate collectors (on collector supports)
Observe the information on securing collectors on page 98.
Viessmann offers 2 collector supports for fixing the collectors:
■ With a
variable angle of inclination
(snow loads up to
2.55 kN/m
2
, wind speeds up to 150 km/h):
The collector supports are pre-assembled. They consist of the
base rail, collector support and adjustable support with holes for
adjusting the angle of inclination (see the following chapter).
■ With
fixed angles of inclination
of 30°, 45° and 60° (snow loads
up to 1.5 kN/m
2
, wind speeds up to 150 km/h):
Collector supports with footplates (see page 113 onwards).
For this version the angle of inclination is calculated from the dis-
tance between the footplates.
Cross braces are required for 1 to 6 collectors connected side by
side to secure the support.
