Table 1.1  Collector types and article numbers

 

>

For the flat collector article number please see the 
identification plate on the upper collector edge.

Vaillant flat collectors are available in different versions: 
A variant for the horizontal collector position (VFK H) 
and a variant for the vertical collector position (VFK V).

The instructions apply to multi-row in-roof mounting of 
Vaillant flat collectors. In this instance, a collector array 
is integrated into the roof.

The collectors are arranged on top of and next to one 
another: 

 

– 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
