Step 3: Snap chalk line Step 4: Remove tiles and drill holes
Step 5: Attach tile clips Step 6: Attach channels
Snap a vertical chalk
line down the roof for
aligning the channel
ends. Each channel
gets 3 tile clips for the
8-foot collectors; 2
clips for the 12-foot-
ers. If working with
curved tiles, the clips
go on the tile high points. Temporarily move the
channels aside.
A. Start with the clips
at the bottom chan-
nel, remove the tile
directly above each
clip. If the tile has a
short nail into bat-
ten strip, a nail bar
may be helpful.
B. Using a 1/4” ma-
sonry bit, drill out the existing high point nail
holes. (not the holes in the tile valleys)
A. Choose the tile clip
hole that will allow
the channel to be
mounted closest to
the tile lip.
B. Secure the clips
using the appropri-
ate length ¼” lag
screws.
C. Lag through the drilled tile hole, batten strip,
underlayment, and sheathing. Note: Snug only or
tile will crack.
A. Align the channel
end with the chalk
line and slide into
place under the
tile clips.
B. Secure channel to
clips with provided
#14 self-tapping
screws.
C. Repeat procedure for next channel up, work-
ing up the roof. Note: Install the upper roof jack
before the top channel.
Step 8: Mount Collectors Step 7: Lay corrugated sheet
Lay collectors on
substrate with top
headers hanging
over substrate.
Install and adjust
header straps so
that top headers
remain hanging
over and touch-
ing the end of the sheet. Install the body straps.
When installing additional collectors, the additional
channel ends should be aligned flush against the
others.
A. Lay two pieces
of the corru-
gated sheet on
the channels
with overlapped
ends. Adjust to
a total length of
94” for 8’ col-
lectors or 142”
for 12’ collectors and secure together with a
#6 screw. Slide sheet until the ends hang over
equally above and below the channels.
B. Center sheet equally side–to-side between the
bases. Drive a #6 screw into the channels at
every other valley. Clean away all metal shav-
ings.
