    6 Flat-roof mounting Flat-roof mounting With flat roof installation, the tube collectors are fas- tened to frames. The flat roof frames allow for a flexible installation with an angle of 30 °, 45 ° or 60 °. Also note that the height of the mounting rails is varia- ble, in order to compensate for small floor irregularities.
