7) Proceed to the lower chalk line previously snapped on

the roof for the hold-down strap brackets. Mark a hole 2"

(5cm) to the side of the first collector and continue mark-

ing holes on the chalkline centered exactly between the

absorber surfaces until you reach the last collector.

Mark the last hole the same 2" (5cm) to the side of the

last collector. Drill a pilot hole and apply sealant at each

of these locations. Bolt the hold-down strap brackets on

the roof. Refer to Figure 6. It is OK to step on the col-

lectors as long as you stay one foot away from the top

and bottom headers. Mark the holes for the bottom hold-

down strap by measuring up 16" (40cm)from the outside

of the bottom header and again centering them between

the absorbers and 2" (5cm) away from the first and last

collector.

Figure 6

Slip one end of a hold-down strap through the slot in the

hold-down strap bracket at the end of the row, then through

the strap clamp and out through the other slot in the hold-

down bracket. Pull about 3" (7-8cm) of the strap through

Figure 7

and bend it back toward the clamp. Refer to Figure 7.

Slip the loose end of the strap through the strap clamp

and pull it tight. Clamp screw (A) should be tightened

securely, but not over-tightened to the point where the

clamp is distorted. Refer to Figure 8. Bring the remain-

ing strap end across the collector face, passing through

Figure 8

both slots in the bracket located on the other side of the

collectors. Pull the straps taut against the face of the

collector. Repeat this procedure for the remaining hold-

down strap. Refer to Figure 9.

8) Install the vacuum relief valve in the outlet header of

each row. This will be located at the opposite end of the

row that is connected to the collector outlet pipe. Refer

to figure 2, 11, and 12.

9) Install an end cap in the inlet header of each row,

opposite the end that is connected to the collector inlet

pipe. Refer to Figures 2, 11, and 12.

10) INSPECT THE INSTALLATION AND CHECK ALL

CLAMPS FOR PROPER POSITION AND TIGHTNESS.

Installation Over Roof Vent Pipes

Collector models with intermittent sonically welded plates

can be installed over or around different diameter roof vent

pipes or other obstructions up to 2" (63mm) in diameter.

After snapping the top chalk lines but before marking and

pre-drilling for your outlet header brackets, locate the seam

in the collector nearest to where the vent pipe is to come

through. Separate by pulling up on top plate, and pushing

down on the lower plate. Should the vent pipe protrude

near a sonic tack weld, it will have to be cut apart. Using a

sharp utility knife, cut through the weld while pulling the two

plates apart. Lay the collector over the vent pipe, keeping

the vent pipe at least 12" (30.5cm) away from a header. It

will be easier to complete an installation by mounting this

collector first and then working away from it.
