All persons working on roofs should have successfully completed a fall-safety course and should be properly equipped with appropriate safety equipment.

WARNING

After completion of the collector mounting and prior to system charging the collectors must be covered by a blanket of 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

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 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.

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

Install the collectors as described in the Spanner Mounting instructions.

SPANNER MOUNTING

In spanner mounting after the mounting feet are positioned correctly, a 3/8” hole is drilled between the rafters (see Figures 15 and 16 for placement of drill holes). Roof sealant is applied between the hardware provided and the roof. The bracket is then positioned over the 3/8” hole using sealant between the bracket and the roof. A piece of stainless steel 3/8” all-thread is then inserted through the hole. A washer and nut secures the all- thread to the bracket (be sure to apply sealant/caulk underneath the washer and on top of the nut). The all-thread rod should extend about 4”

below the roof rafters. Drill a 3/8” hole in a 2” x 4” piece of lumber and insert the all-thread rod through it. The 2” x 4” should span 2 rafters. With a lockwasher and fender washer secure the all-thread to the 2” x 4”. Tighten down until the bracket is tightly secured to the roof. Be careful not to over-tighten and dish out the roof underneath the bracket. For best results insert a spacer block next to the all-thread that is the width of the rafter to avoid deformation of the roof. (See Figure 14)
