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 your installer if other mounting means are

required for your installation.
1. After locating the mounting points from Figure 1 for

vertical mounting, Figure 2 for horizontal mounting,

and Table 1, layout the roof as specified and drill 5/16”

holes between the rafters where indicated.

2. Insert the flashing so the top part is under the next row

of shingles and the flashing hole/grommet aligns with

the mounting hole. See Figure 3.

3. The compression bracket washer is positioned over the

flashing seal with the concave side towards the seal.

See Figure 4.

4. The mounting bracket is then placed on the compression

bracket washer.

5. A 12” length of stainless steel 5/16” all-thread is then

inserted through the hole and a stainless steel nut, lock

washer, and EPDM bonded washer secures the all-

thread to the mounting bracket. The all-thread should

extend about 4” below the roof rafters.

6. Fabricate spanners, one for each mounting bracket,

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 4.

7. 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 4.

8. With a stainless steel nut, lock washer and fender

washer secure the all-thread to each spanner. Tighten

down until the mounting bracket is tightly secured

to the roof (approx. 97 inch pounds). Be careful not

to overtighten and dish out the roof underneath the

mounting bracket.

9. Repeat steps 2-8 for the remainder of the mounting

bracket locations.

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 5.

Preserving the integrity of the roof membrane is the

most important roofing consideration. Ensure that all roof

penetrations required to plumb and mount the solar collector

are properly flashed and sealed in accordance with standard

roofing 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 specific mounting procedures. Consult

your local building department.
Install the collectors as described in the Spanner Mounting

instructions.

CAUTION

ALL PERSONS WORKING ON ROOFS SHOULD

HAVE SUCCESSFULLY COMPLETED A FALL SAFETY

COURSE AND SHOULD BE PROPERLY EQUIPPED

WITH THE APPROPRIATE SAFETY EQUIPMENT

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.

WARNING

The most important structural consideration is to securely

anchor the solar collector and the mounting hardware to the
