SM SYSTEM LAYOUT SOLAR MOUNT INSTALLATION GUIDE PAGE PLANNING YOUR SOLARMOUNT INSTALLATIONS The installation can be laid out with rails parallel to the rafters or perpendicular to the rafters. Note that SOLARMOUNT rails make excellent straight edges for doing layouts. Center the installation area over the structural members as much as possible. Leave enough room to safely move around the array during installation.
SM SOLAR MOUNT CODE COMPLIANCE NOTES C INSTALLATION GUIDE PAGE SYSTEM LEVEL FIRE CLASSIFICATION The system fire class rating requires installation in the manner specified in the SOLARMOUNT Installation Guide. SOLARMOUNT has been classified to the system level fire portion of UL 1703. This UL 1703 classification has been incorporated into our UL 2703 product certification. SOLARMOUNT has achieved system level performance for steep sloped roofs.
SM SOLAR MOUNT ROOF ATTACHMENT & L-FEET D INSTALLATION GUIDE PAGE ROOF PREPARATION: Layout and install flashing at rafter locations determined per Design and Engineering Guide. DRILL PILOT HOLES: Center the roof attachment over the rafter and drill a pilot hole(s) for the lag bolt(s). NOTE: Determine lag bolt size and embedment depth. FLASHING INSTALLATION: Insert the flashing so the top part is under the next row of shingles and the hole lines up with the pilot hole.

SM APPENDIX A SOLAR MOUNT A System Certification PAGE The SOLARMOUNT system has been certified and listed to the UL 2703 standard (Rack Mounting Systems and Clamping Devices for Flat-Plate Photovoltaic Modules and Panels). This standard included electrical grounding, electrical bonding, mechanical load and fire resistance testing. In conducting these tests, specific modules are selected for their physical properties so that the certifications can be broadly applied.
