11.3 Vacuum tube 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
of 25 to 50° (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 a
fixed angle of inclination
(snow loads up to 1.5 kN/m
2
,
wind speeds up to 150 km/h):
Collector supports with mounting feet (see page 115 onwards).
For this version the angle of inclination is calculated from the dis-
tance between the mounting feet.
Cross braces are required for 1 to 6 collectors connected side by
side to secure the support.
