Flashing refers to thin,continuous pieces of sheet metal or other impervious material installed to prevent the passage of water into a structure from an angle orjoint. Flashing generally operates on the principal that,for water to penetrate a joint,it must work itself upward against the force of gravity or in the case of wind-driven rain,it would have to follow a tortuous path during which the driving force will be dissi- pated. Unirac offers(lashings to be used specifically with Unirac standoffs. These flashings are collared,thereby eliminating the need for the use of sealant between standoff and flashing. The flashing slides over the standoff,under the shingle above,and over the shingle below. The following installation instruction provides an explanation of planning and installation of three different applications. i I Standoffs&Flashln s Installation Manual907.2 ; UNIRAC Planning and installation There are many possible configurations of standoffs and flashing.The three examples here illustrate major product varieties and installation settings.

SolarMotmt products(page 26). The installer is solely responsible for: Complying with all applicable local or national building codes, including any that may supersede this manual; • Ensuring that Unirac and other products are appropriate for the particular installation and the installation environment; • Ensuring that the roof, its rafters, connections, and other structural support members can support the array under all code level loading conditions (this total building assembly is referred to as the building structure); • Using only Unirac parts and installer-supplied parts as specified by Unirac(substitution of parts may void the warranty and invalidate the letters of certification in all Unirac publications); . Ensuring that lag screws have adequate pullout strength and shear capacities as installed; • Verifying the strength of any alternate mounting used in lieu of the lag screws; • Maintaining the waterproof integrity of the roof, including selection of appropriate flashing; • Ensuring safe installation of all electrical aspects of the PV array; • Ensuring correct and appropriate design parameters are used in determining the design loading used for design of the specific installation.Parameters, such as snow loading,wind speed, exposure and topographic factor should be confirmed with the local building official or'a licensed professional engineer. 2 SolarMount Unirac Code-Compliant Installation Manual :e'°U N I RAC Part I. Procedure to Determine the Design Wind Load [I.I.] Using the Simplified Method -ASCE 7-05 The procedure to determine Design Wind Load is specified for more clarification on the use of Method 1.Lower design by the American Society of Civil Engineers and referenced in wind loads may be obtained by applying Method Il from ASCE the International Building Code 2009.
