Installation

Multi-row in-roof mounting of Vaillant flat collectors is
always carried out in vertical rows. The flat collectors
have a horizontal orientation (VFK H) or a vertical orien-
tation (VFK V). They are arranged on top of one another
and next to one another in a collector array:
– 2 to 12 collectors next to one another
– 2 or more collectors on top of one another
(depending on roof height)
Furthermore, with the VFK H it is only possible to mount
two collectors on top of one another.
Generally, the installation steps and the instructions
described in this manual are valid for both collector
positions and for all array arrangements.
Any different installation steps are clearly pointed out:
w
Only for the horizontal collector position
s
Only for the vertical collector position
Only when two VFK Hs are on top of one
another
