Roof Attachment Installation
(continued)
Install flange plate shingle (standard)
1. Determine roof type. Inspect the structural integrity of
the roof and the durability of the roof materials.
2. Determine the number of collectors needed for the
installation and the number of required roof attachments
from Table 3B or 3C on page 11.
3. Determine collector connection points (spacing).
Measure the spacing of the rafters or trusses to confirm
the dimensions and prepare for the system layout
(reference the Roof Attachment Spacing Section on
page 12).
4. Caulk (field supplied) around the perimeter of the flange
plate (FIG. 3-22).
5. Using the flange plate as a template, place the flange plate
on the roof and drill four (4) 6 mm holes as shown in
FIG. 3-23. Install the larger screws provided in the kit
into the 6mm holes securing the flange plate to the roof
(caulk around screws before tightening).
6. Install the four (4) remaining smaller screws in the
perimeter of the flange plate as shown in FIG. 3-23 (caulk
around screws before tightening).
7. Cover flange plate with roofing material, sealing it to the
roof (FIG. 3-24).

9. Install the hex bolt with square disk attached into the
opening of the flange plate as shown in FIG. 3-23.
Note: Do not tighten hex bolt until ready to install on the
collector substructure.
10. Thread the hex nut (M8) and washer (M8) onto the bottom
of the hex bolt installed in Step 9.
