Roof Attachment Installation
(continued)
Install flat tile hook
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. Number two (2) tiles, one above the other. The top tile
will be removed to install the flat tile hook.
5. Remove the top tile from the roof (set aside for
reassembly).
6. Place the tiled roof hook over the roof batten of
the bottom tile (FIG. 3-11).
7. Place the metal sheet provided in the kit under the flat
tile hook (FIG. 3-11). Using the nails provided in the kit,
secure the metal sheet to the roof substructure (FIG.
3-11).
8. Secure the tiled roof hook to the roof substructure using
the screws provided in the kit (FIG. 3-11).
9. Replace the tile removed in Step 5.
Note: It may be necessary to grind the top tile to assure a
better fit (FIG. 3-12).
