Variations for Shallow Pitch or Flat Deck Roofs
On shallow pitch roofs (less than 8°) of
metal or fibreboard materials, the frame
may be installed without using the pipe
legs, provided that the inclination of the
solar collector remains greater than 8°.
On flat roofs, the assembled frame may
be installed without the baseplates.
Provided the roof material is structurally
suited, the frame may be bolted directly
to it.
