SCH Collectors Installation & Operation Manual

3 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).

8.Slide the square disk onto the hex bolt (see FIG. 3-23).

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.

11.Repeat Steps 4 - 10 until installation is complete.

Install hex bolt onto collector substructure (reference Section 4 - Collector Installation)
