Procedure:
1. Choose attachment site, allowing for subsequent pipe
penetration.
2. Ensure that two bolts are inserted into the channel of the upper
and lower profile rails, before the upper and lower riser struts are
bolted to the profile rails.
3. The distance between the collector support rails should be
slightly larger than the distance between the upper roof hooks / U
strips which have already been installed on the roof.
4. On the roof hooks / U strips, the long sides of the pivot brackets
are screwed into the middle drill holes. The short side should be at
the top.
5. On the lower roof hooks / U strips, the short side of the second
pivot bracket is bolted to the first pivot bracket.
6. Cut the riser struts of the standoff to the proper length for the
required angle. For 15° tilt, in the case of vertical installation (or
30° in the case of horizontal installation), only one strut is needed
for each pivot point. For 30° vertical installation, the riser struts are
bolted together as illustrated in Figure 28. For angles between 15°
and 30°, the struts may be bolted together through the intermediate
holes.
7. The upwards facing short side of the pivot bracket attached to the
upper roof hook / U profile is now bolted to the bottom of the riser
strut.

5.4 15-30° Tilt Mounting on a Pitched Roof
IMPORTANT: INSTALLED HEIGHT MUST NOT ExCEED 60 FEET.
Stiebel Eltron provides tilting frame mounting kits for both vertical
and horizontal collector layouts, part numbers SFT004 and SFT004H,
respectively.
Figure 26 shows the SFT004 kit and Figure 27 shows
the SFT004H kit. The SFT004 frame tilt kit (SFT004H in the case of
horizontal mounting) provides adjustment of the collector array from
15° to 30°). For mounting on a roof, two (2) tilt kits are needed per
collector frame, for either vertical or horizontal configurations.
Stiebel Eltron tilt mount kits are generally not recommended for
mounting upon flat roofs, walls, or the ground. Instead, the 45°
or 30/60° mounting systems are more appropriate for mounting to
structures other than pitched roofs.
