How to Conﬁgure Your System

First calculate the spans and penetration count. See span tables in structured engineering letters under the resources tab of the SnapNrack website. Determine site conditions: general building height, array pitch, the wind speed, and snow load or topographical condition. Find appropriate railspan from table.

Span Table Example

Building Height 0 - 30 ft Array Pitch 16° 2012 IBC Wind Speed 120 mph Snow Load 8 lbs/ft Topo. Cond. None Rail Span 104" Rail Span on 24" spacing roof 96" (8 ft) Do edge/corner reductions apply Yes, shaded cell Edge Zone Span 72" (6 ft) Corner Zone Span 24" (2 ft)

Series 100 UL Roof Mounted System

Safety Guidance

- Always wear the proper OSHA approved safety equipment when working on a roof .

- Safety equipment should be checked annually for wear and quality.

- Always wear proper eye protection.

- When walking on the roof avoid walking on installed rails. If this is unavoidable check L-feet for fatigue before ﬁnal installation.

- Appropriate fall protection gear should be used. Extreme caution should be used when near the edge of the roof.

*CS-Consult Structural Engineer

Notes

- The UL Listing covers bonding for a load rating up to 45 psf.

- See Appendix A for the list of modules that have been tested with the Series 100 UL system.

- These systems have been evaluated for module to system bonding, only to the requirements of UL Subject 270.

- This system has also been evaluated for a Class A System Fire Classiﬁcation for a steep-sloped roof with Type 1 and Type 2 modules.

- Installing Contractor is responsible for veriﬁcation that attachments to roof framing are fully engaged into appropriate structural member and that structural member is adequate for support of roof mounting component and associated loads.

 Measure the roof surfaces and develop an accurate drawing, including any obstacles such as chimneys and roof vents.  If plans are available, check to make sure that the plans match the ﬁnal structure.  Review the shading pattern across the roof surface from the residence itself, from adjacent structures, and from other nearby features such as trees.  Identify any roof access areas or keep-out areas as required by the local jurisdiction.

 Conﬁrm roof construction, type, and condition.  Assess roof rafter size, material, and spacing to conﬁrm that the structure is

sound and can support the additional load of the array.  Identify any construction anomalies that may complicate the process of locating rafters from the roof surface.  If you ﬁnd structural problems such as termite damage or cracked rafters

Series 100 UL

that may compromise the structure’s integrity, consult a structural engineer.

Surveying and Layout

Develop a Layout

Using the information collected in the site survey and from the span tables, complete a system layout showing array location and distances from key roof features. Include any information necessary for the permitting process.

Typically, PV modules are installed in portrait mode, with the long side of the module running up the roof slope and the rails running horizontally across the roof perpendicular to the roof rafters, which commonly run down slope.

Arrays can also be installed in landscape mode, with the modules oriented so that their long edge runs horizontally across the roof and the rails run up the roof slope. Landscape mode is typically used in cases where the roof has been constructed with structural elements running horizontally across the roof, but can also be used on standard residential buildings for a variety of reasons including to facilitate a convenient layout. When laying out the array, be sure to leave space for the module clamps on the rails. Module mid clamps are installed between modules in a row and require 0.5" of space between the modules.

Adjustable end clamps require 1.5" of extra rail to extend past the end of the module frame. If using the Universal End Clamp, the rail is ﬁrst cut ﬂush to the module using the rail

cutting tool.

When installing multiple rows of modules, a minimum spacing gap of 1/8" should be used between rows.

Submit array plans to local permitting jurisdiction and proceed with the roof layout only when all permits for the project have been granted by the authority having jurisdiction.

Series 100 UL Surveying and Layout

Tips and Tricks

- Layout the entire array on the roof by drawing all of the corners of the modules on the roof with a roof marking crayon.

- Use a chalk line to help identify the rest of the roof penetrations

- When leveling rails, hand tighten the hardware to easily level and position the rails. Once rails are level, fully tighten hardware to speciﬁed torque.

Transfer the array layout to the roof using a roof marking crayon to mark the inside and outside corners of the array. Locate the estimated rafter positions and mark them in the array area with a roof marking crayon.

Transfer rail and estimated attachment locations to the roof, noting that attachments will be located at intersections of rails and rafters. Layout rails such that module frame ends do not overhang mounting rails by more than 25% of total module length.

Series 100 UL Universal Tile Roof Hook

Step-by-Step Instructions

1) Use pry bar to remove roof tile where the base will be installed. Locate the rafter underneath the decking of the roof by locating under the eave, in the attic, or by tapping the roof surface with a hammer.

2) Align the base over the rafter so the hook can enter at the valley of a tile and not extend beyond the edge of the base. Drill two pilot holes in the center of the rafter. If the rafter is not found then seal the pilot hole immediately with sealant.

) Apply rooﬁng sealant to the bottom of the base and directly onto each lag screw. Attach the base with two 5/16” lag screws with washers at a minimum 2 ½” lag shank embedment into the rafter. Tighten the lag screw to seat using a hand wrench.

5) Work channel nut into groove

7) Optional deck-level ﬂashing

6) Attach Tile Hook arm to base

8) Replace tile and install rail

4) Insert the top end of the arm into the groove at the top of the base. The arm will move freely in the base until the channel nut is tightened. Position the arm over the valley of the tile below, then lower the arm down.

5) As you lower the arm you can work the channel nut into the lower groove of the base without removing the channel nut.

6) Ensure the hook is aligned with the valley of the tile. Tighten the bolt in the channel nut and be sure the arm fully seats to the base. The arm will work in any position on the base independent of the lag screw location.

7) If deck-level ﬂashing is required, integrate roof felt or a ﬂexible ﬂashing with the existing underlayment and over the Tile Hook.

8) Replace the roof tiles and install SnapNrack Standard Rail directly to the available channel nut on the Tile Hook arm.

1) Prepare underlayment

3) Apply ﬂashing

2) Peel o backing

4) Roll ﬂashing

Series 100 UL Flat Tile Roof Hook Optional Deck-Level Flashing

Step-by-Step Instructions

1) Prepare the underlayment surface for adhesion. The surface should be dry, clean and free of any dirt, dust or foreign matter that may prevent adhesion. Clean the surface around the Tile Hook with a brush of medium-sti bristles. If necessary, prime the surface with compatible spray or paint primer.

2) Peel o the backing from a 9-in. square of ﬂexible ﬂashing.

) Apply ﬂexible ﬂashing centered laterally over tile hook and abutted to the tile hook arm. Ensure tape adheres to the corners between the edges of the Tile Hook and the underlayment as well as over the lag screw heads and tile hook surface.

4) Press and smooth out any creases or air bubbles with a roller to maximize contact of the ﬂashing adhesive to 100% of the surface and Tile Hook.

5) Peel o backing 6) Roll strip

5) Peel o the backing from a 4-in. by 1" strip of ﬂexible ﬂashing.

6) Apply the strip with 2" laps at the top and side edges of the square ﬂashing. Roll out any creases or air bubbles between the strip, the ﬂashing and the underlayment surface.

Notes

- SnapNrack recommends testing underlayment surfaces for adhesion. If adhesion is found to be marginal, then a primer is recommended to ensure optimal adhesion. Refer to ﬂexible ﬂashing manufacturer’s technical data for primer recommendations.

- SnapNrack recommends using Protecto Wrap Protecto Seal 45 waterprooﬁng membrane, or equivalent, as the ﬂexible ﬂashing and lap material.

Step-by-Step instructions

1) Set all of the rails into the attachments by snapping the channel nuts into the side channel of the standard rail. Connect multiple lengths of rail end to end with the SnapNrack splice.

2) Find the highest attachment point of the roof, and set that attachment point to the lowest adjustability. Level the bottom rail of the array to the roof by tightening attachment points. Torque silver hardware to 10-16 ft-lbs and black hardware to 8-10 ft-lbs.

) Using a string line or spare rails run from the bottom rail to the top rail and raise the top rail, then set the desired pitch of the array by adjusting the top rail. Add leveling spacers if needed.

5) Level remaining rails to pitch

6) Tighten hardware

4) Level the top rail by moving the string line down the length of the rail, matching pitch over the entire length of the array.

5) Level the remaining rails to the string line, working out from the middle rail. Add leveling spacers if needed.

6) Tighten all racking hardware, torque silver hardware to 10-16 ft-lbs and all black hardware to 8-10 ft-lbs.

Notes

- SnapNrack engineered systems should only be used with SnapNrack components and hardware. Any alternate application may void the warranty and structural calculations could become invalid.

- The minimum stando height between the modules and roof is as follows:

- REC Solar, Yingli, and Suniva modules: 4.00"

- ReneSola modules: .9"

- Trina Solar modules: 4.5"

Class A Fire Classifcation

The system has been evaluated for a Class A System Fire Classiﬁcation for a SteepSloped Roof using Type 1 and Type 2 modules. In order to maintain the System Classiﬁcation, modules must be mounted in the portrait orientation, and clamped to the mounting rails beween 0 and 12" from the top and bottom edges of the module.

Series 100 UL Installing and Leveling Rails

Step-by-Step instructions

SnapNrack Rail Splice

1) Align sections of rail so that ends butt up to each other.

2) Place rail splice assembly in to the side channel of rail making sure the base is seated all the way to the back of the channel and front of splice is up against upper lip of side channel with lower lip of channel in groove on lower edge of splice. Splice should be centered on gap where rails come together.

) Lift up on splice insert, either by lifting up on bolts or with ﬁngers on both sides of insert to make sure insert is as high in channel as it can go. While lifting up on insert, tighten bolts by hand to secure insert in channel. Note: loosening bolts prior to lifting up insert to engage it into channel will provide play between insert and channel for proper positioning.

4) Using a socket wrench, tighten up bolts on splice to secure splice to rails. Torque silver hardware to 10–16 ft-lbs and black hardware to 8–10 ft-lbs.
