STEP 6: INSTALL BODY STRAPS
Apply roof sealant at lag screw location, 1” from collector edge, 4” down
from the top header. Drive a lag screw through the base.
Orient the slot for the strap horizontally and tighten lag screw. Lay the
strap in the slot of the base and screw down the cap until tight. Install base
on opposite side of the three panels 1” from the collector edge. Stretch
strap across panels and screw down with cap until tight. Install another
base and cap between panels. Measure to center of collectors and install
a center body strap following previous procedure. Install the third collector
body strap 4” above the bottom header. Straps will allow for expansion
and contraction of the solar collectors.
STEP 7: INSTALL LOWER ROOF JACK
At the lower header end, diagonally opposite the upper outlet header end,
install the lower inlet header roof jack 4-6 inches out from the header, as de-
tailed in Steps 4 & 5 above. Note: This jack does not get a sensor.

Step 1: Attach bases to channels
Step 2: Determine layout
A. Place upper
header channel
against the lip of
the second tile
row down from the
ridge. Note; If in-
stalling a PV Panel
Kit above solar
collectors, place
upper channel against fourth tile.
B. Place the first body channel against the lip of
the next tile row down.
C. Measure down the roof from the first body
channel and place the bottom body channel
against the lip of a tile row at approximately 7’
for 8-foot long or 11’ for 12-foot long collectors.
(Measurement will vary with tile spacing)
D. Place remaining channel(s) in between, spaced
as evenly as possible.
The configura-
tions depicted in
the installation
sequence show
8-Foot Collectors.
Attach bases to
channels using
the large #14
screws. The up-
per header chan-
nel gets bases with slots aligned vertically for the
header straps. All body channels get bases with
slots aligned horizontally for the body straps.
