Header Inserts (Part #50055-1 for
1 1/2”; #50055-2 for 2”) are used
in special situations where
unusually high stagnation
temperatures are expected,
such as in a desert climate
or where abnormally high
system pressures may occur.
Use four (4) inserts per collector.

The Optional Supplemental Hurricane Collector
Hold-Down Kit (Part #12035-1 for 1 1/2”, #12035-2 for
2”) when used in addition to the basic collector installa-
tion kit, meets collector mounting standards in Florida
Counties requiring resistance to 120 mile per hour winds.
In regions where high winds are prevalent, special
mounting precautions may be necessary to secure
brackets to the mounting surface. One method, using
threaded rods, is shown here.

MOUNTING THE SOLAR COLLECTORS
Refer to Figure 1 throughout this section. When mounting
the collectors, always make provisions for inlet connec-
tions at the bottom header and outlet connections at the
top. The outlet headers must be pitched a vertical dis-
tance of at least 8” (20cm) above the inlet headers to
assure proper drainage and uniform flow. Plan the col-
lector location to allow at least one foot on all sides of the
row of collectors for mounting brackets and piping. The
outlet pipe for each row of collectors must be connected
diagonally opposite the inlet pipe. Refer to Figure 2.
