FAQ

Integrated Grounding

  • Is UL 2703 a new standard?

    UL 2703 is currently an Outline of Investigation, which means it has not yet been accepted by ANSI as a standard. However, while the acceptance process is underway, products can still be listed to the outline, and it's just as valid as a listing to an established standard.


  • How is the grounding different from WEEBs?

    The IronRidge listing covers both the modules and the rails. This means that the module frames and rails are considered an electrically continuous system, requiring fewer jumpers and lugs.


  • How many times can the clamp be loosened and re-tightened on the module?

    The Grounding Mid Clamp has been tested and certified to re-tighten a minimum of ten times.


  • Can an outdoor-rated bonding jumper be used instead of an IronRidge Grounding Strap?

    Alternative bonding jumpers are not included within the UL 2703 listing. Use of these products may cause concern with the Authority Having Jurisdiction (AHJ), and could lead to a failed inspection.


  • Does the module manufacturer need to list IronRidge as a grounding means in their installation manual?

    The UL 2703 certification process includes extensive testing of the IronRidge components with the module. These tests are identical to the tests performed in the module listing process (UL 1703). As a result, the UL 2703 listing covers both products, not just the mounting components.


  • Will it void the module warranty if the IronRidge clamp is not listed in the module's manual?

    The IronRidge System does not harm the module, but you should always confirm warranty questions with the manufacturer before installing.


  • Will piercing the module anodization cause corrosion in coastal environments?

    The UL 2703 certification process included extensive environmental and corrosion testing. The high quality stainless steel used in the IronRidge Grounding Mid Clamps does not cause significant galvanic corrosion, even in extreme environments.


  • Can microinverters or power optimizers be used with the Integrated Grounding System?

    The UL 2703 listing does not cover microinverters or power optimizers, but it may be possible to ground these devices to IronRidge rails. You must ensure the grounding method complies with the documentation provided by the manufacturer.

FlashFoot

  • What is the warranty of the product?

    The FlashFoot has a 20 year warranty. And, like all IronRidge products, the FlashFoot’s expected useful life is greater than 30 years.


  • Will it preserve the roof’s warranty?

    The FlashFoot is designed to work with all standard composition shingle roofs. However, you must review the roof manufacturer’s warranty information to ensure compliance. As well, you should contact the original roofer and work with them to preserve the labor warranty on the roof.


  • What is the minimum roof slope to use FlashFoot?

    The FlashFoot is designed for pitched roof applications, and can be installed on roofs with a slope of 7-27 degrees.


  • Is the product certified?

    FlashFoot is certified for compliance with the 2006 & 2009 International Building Codes (IBC) & International Residential Codes (IRC).


  • What is IAPMO-ES?

    IAPMO-ES prepared the Evaluation Report for FlashFoot. IAPMO-ES is an ANSI accredited provider of building product certification services per ISO/IEC 17065, making it capable of certifying products as compliant with multiple building codes.


  • How was FlashFoot tested?

    FlashFoot was tested for structural and waterproofing performance. Mechanical testing conformed to the standard for Testing and Analysis of Joist Hangers and Miscellaneous Connectors (EC002-2011), and rain testing conformed to the Underwriters Laboratory Standard for Gas Vents (UL 441-96 Section 25).


  • Why does the Load Distribution Plate stick out from the bottom?

    The Load Distribution Plate sits “proud” of the flashing layer by approximately 1/8” because this improves the FlashFoot’s ability to adapt to thicker shingle types and protect against deflection or deformation during installation.


  • Can the mounting rail pull out of the open-top L-Foot?

    No. If the attachment hardware is properly tightened, there is more than enough friction to prevent slipping. In addition, there is a lip on the top of the L-Foot to prevent loose hardware from slipping out.

Class A Fire Rating

  • What is the new fire rating requirement?

    New language in the 2012 IBC states that a roof mounted photovoltaic system must have the same fire classification as the roofing material the system is installed upon.


  • Where is this requirement listed in the code?

    2012 IBC: 1509.7.2 Fire classification. Rooftop mounted photovoltaic systems shall have the same fire classification as the roof assembly required by Section 1505.


  • What is the definition of “system”?

    The system specified in the code includes the roof covering material, PV mounting system and PV modules. Together all three are tested to determine the system fire rating.


  • What determines Fire Classification?

    Fire Classification refers to a fire-resistance rating system for roof covering materials based on their ability to withstand fire exposure.

    • Class A - effective against severe fire exposure
    • Class B - effective against moderate fire exposure
    • Class C - effective against light fire exposure


  • Where is Class A required?

    The general requirement for roofing systems in the IBC refers to a Class C fire rating. Class A or B is required for areas such as Wildland Urban Interface areas (WUI) and for very high fire severity areas. Many of these areas are found throughout the western United States. California has the most Class A and B roof fire rating requirements, due to wild fire concerns.


  • What roofing materials are covered?

    All fire rated roofing materials are covered within this certification including composition shingle, clay and cement tile, metal, and membrane roofs. The testing is conducted on a basic roof design that represents all listed fire rated roof constructions.


  • What if the roof covering is not Class A rated?

    The IronRidge Class A rating will not diminish the fire rating of the roof, whether Class A, B or C.


  • Do solar modules have a Fire Class rating? What is a “module type”?

    The new UL1703 standard with the updated fire test introduces the concept of a PV module Type that is based on 4 construction parameters and 2 fire performance parameters. The purpose of this classification is to certify a mounting system without having to test it with every module.


  • What attachments and flashings are deemed compatible with Class A?

    Attachments and their respective flashings are not constituents of the rating at this time. All code-compliant flashing methods are acceptable from a fire rating standpoint.


  • Are standard mid clamps covered within the certification?

    Mid clamps and end clamps are considered part of the PV “system”, and are covered in the certification.


  • Am I required to install skirting to meet the fire code?

    No, IronRidge achieved a Class A fire rating without any additional racking components.


  • What mounting height is acceptable?

    UL fire testing was performed with a gap of 5”, which is considered worst case in the standard. Therefore, the rating is applicable to any module to roof gap.


  • What Roof Mount configurations are covered?

    IronRidge is currently Class A certified for Flush Mount applications parallel to roof with Type 1 and 2 modules. Tilt Mount systems are certified with Type 1 modules.


  • What if I have a Class C roof, but the jurisdiction now requires Class A or B?

    Generally, older roofs will typically be “grandfathered in”, and will not require re-roofing. However, if 50% or more of the roofing material is replaced for the solar installation the code requirement will be instated.


  • What are the requirements for fire setbacks?

    Every jurisdiction enforces their own requirements related to fire setbacks for rooftop solar, and these requirements are not related to the fire rating of the system.
