CAUTION

ALL PERSONS WORKING ON ROOFS SHOULD

HAVE SUCCESSFULLY COMPLETED A FALL SAFETY

COURSE AND SHOULD BE PROPERLY EQUIPPED

WITH THE APPROPRIATE SAFETY EQUIPMENT

WARNING

AFTER COMPLETION OF THE COLLECTOR
MOUNTING AND PRIOR TO SYSTEM CHARGING THE
COLLECTORS MUST BE COVERED BY A BLANKET OR
OTHER MEANS TO AVOID SOLAR RADIATION FROM
HEATING THE COLLECTORS. THE SURFACES OF THE
COLLECTOR CAN BECOME EXTREMELY HOT AND
COULD POSE A BURN HAZARD.

The most important structural consideration is to securely

anchor the solar collector and the mounting hardware to the
structural members of the roof with the stainless steel hardware
provided. The solar collector must be attached to the mounting
hardware as detailed in Figure 17.

Preserving the integrity of the roof membrane is the

mostimportantroongconsideration.Ensurethatallroof

penetrations required to plumb and mount the solar collector

areproperlyashedandsealedinaccordancewithstandard
roongpractices.

If the region is subject to hurricane conditions, additional
steps may be required to secure the collector and mounting
hardware to the structural members. In certain areas of the
country, local building codes may require collector wind load

testingorprescribespecicmountingprocedures.Consult

your local building department.

Install the collectors as described in the Tile Roof Mounting
instructions.

TILE ROOF MOUNTING / SPANNER MOUNTING

Although there are other installation methods for mounting
solar collectors, it has been determined that the spanner
mounting method is the most suitable for this application.
Consult with you installer if other mounting means are
required for your installation.

1. Locate the mounting points for the mounting brackets
per Figure 1 for vertical mounting or Figure 2 for
horizontal mounting and Table 1. Layout the roof as
specified.

Figure 4.

2. Determine which course of the roof you wish to
penetrate. It may be necessary to remove a few tiles to
locate the rafter locations. See Figures 3 & 4.

Figure 3.

Figure 5.

Figure 6.

3. Determine the location of the flashing and cut a slit in the
roofing paper so the upslope edge of the flashing can
slide under the paper when installed. See Figures 5 & 6.

4. Once the flashing location has been determined, mark
the position of the center of the flashing bushing on the
roof paper. Remove the flashing.

5. Drill a 5/16” hole between the rafters at the center mark
of the flashing bushing.

using a 2” x 4” or similar lumber. Spanners must be
long enough to span at least two rafters. In the attic or
crawl space drill a 5/16” hole through each spanner and
insert the all-thread through it. Secure each spanner to
the rafters with decking or wood screws. See Figure 16.

9. Fabricate spacer blocks, one for each mounting bracket,
using a 2” x 4” or similar lumber the same width of the
rafter next to each all-thread. Place spacer blocks next
to the all-thread between the spanner and roof. Secure
each spacer block to the spanners with decking or
wood screws. Spacer blocks are necessary to avoid
deformation of the roof. See Figure 16.

10. With a stainless steel nut, lock washer and fender
washer secure the all-thread to each spanner. Tighten
down until the compression bracket washer is tightly
secured to the roof and flashing (approx. 97 inch
pounds). Be careful not to over tighten and dish out
the roof underneath the mounting bracket washer and
flashing. See Figure 16.

Figure 7.

6. Slide the flashing back under the roof paper and position
it so that the center of the flashing bushing is aligned
with the center of the drilled hole.

7. A piece of 12” length of stainless steel 5/16” all-thread
is then inserted through the hole in the roof and the
flashing bushing. Attach the compression bracket
washer and 5/16” x 3/8” SS reducer coupler to the 5/16”
SS –all thread as shown. The all-thread should extend
about 4” below the roof rafters. See Figures 7 & 16.

8. Fabricate spanners, one for each mounting bracket,

Figure 8.

11. Install an Ice & Water Shield (not included) around the
flashing to provide a water tight seal. See Figure 8.
