Home My WebLink AboutInstallation InstructionsIVIN Xi -Steel Pier System Effective: August, 2007 ' Installation Instructions FLORIDA ONLY �= By Tie Down Engineering Installation instructions for longitudinal and lateral stabilization of manufactured homes set to specifications of the State of Florida. • Easy installation • 3 square foot pad and Xi -system replace standard support pier and base pad • Screw type pier adjusters... no need to use installation jacks to adjust home to system Steel Pier Systems P/N's #59321 Xi, 12" Pier #59314 Xi, 25.5" Pier #59317 Xi, 36" Pier #59315 Xi, 5' Lateral Strut #59318 Xi, 6' Lateral Strut Block Pier Systems P/N's #59319 Xi, Lateral w/5' Strut #59320 Xi, Lateral w/6' Strut REQUIREMENTS IVY Installation can be made in any type of soil, 4B or better • Florida requires 5' 4" anchor spacing for vertical ties • 4' ground anchors are used with the Xi -system in 4A and 4B soils, except at shear wall or marriage wall locations where loads exceed 3150 pounds. Florida requires that 5' anchors be used at these locations. • Center line or shear wall anchors, that may be required by specific manufacturers, are to be sized according to soil torque conditions. Follow all manufacturers instructions for anchor type and placement in addition to Florida regulations. • Maximum sidewall height is a 96" projection. Higher walls may be used, when the design loads are adjusted accordingly. . • Maximum roof eave is 16" • Main rail spacing must be 99.5" or less • Maximum pier height of the Xi -system is 48" • Instructions are not for use on "Exposure W homes within 1500 feet of the coastline Installation instructions are based on 4200# per pad longitudinal load and 6000# per pad lateral load with one diagonal tie/stabilizer. • Additional vertical anchor ties that are unique to a home's design may be required by the home manufacturer. These locations include shear walls, marriage line ridge beam support posts, and rim plates. P/N 15386 -`s Installation of Longitudinal System (Figure 1) 1. Identify the number of systems to be used on the home using the chart provided. 2. Identify on the location where the longitudinal systems will be installed. 3. Clear all organic matter and debris from the pad site. 4. Place pad centered under beam using the centering mark imprinted on the pad. 5. Press or drive pan into ground until level and flush with prepared surface. 6. Slide Xi -System pier feet into slots in pad so that the Xi -system pier is centered under the I-beam. 7. Raise telescoping extension post to contact the bottom of I-beam, secure with bolt provided, tighten bolt nut. (Figure 1) 8. Turn hex nut on pier height adjuster until Xi -System pier is rigid between pad and I-beam. 9. Install Gator Beam clamps to I-beam on each side of the Xi -System pier. Do not tighten nuts at this time. (Figure 2) 10. Connect struts (open side down) to each side of the.Xi-System pier using the U- bolt provided. Struts are attached to the upper hole in each pier leg and to the flanges on the beam clamps. (Figure 1) 11. Tighten all nuts and bolts on the struts and beam clamps. 1. 2. 3. 4. Installation of Lateral System (Figure 3) Assemble lateral strut by sliding smaller (1-1/2") tube into the larger (1-3/4") tube. Holes should be on the sides of the larger tube and the "flag" up on the larger tube. Attach the end of the smaller tube to the inside of the pan using u-bolts and nuts provided. Attach the flag end of the larger tube to the opposite I-beam using the "J" bolt over the top of the I-beam with the nut & washer provided. (Figure 4) Install a minimum of four(1/4"x3/4') self -tapping screws into the holes provided in the lateral strut so that the two tubes are connected together.

V- a ties areas uired on homes supplied with vertical tie con- nf ion points (per Florida reg tions). Typical Placement Single Section Double SeSpf Triple Section Up tcP16' Nominal t ominaI or Double w/tag up to 48' Nominal When the Xi -System is used only as longitudinal stabilization, systems must be as evenly spaced as possible, no more than 16' from the end of the home. Maximum roof slope for single units & double section is 5/12, for triple sections is 3.5/12, for the above number of systems. Combining Longitudinal and Lateral Stabilization for Florida • Sidewall anchors with vertical ties every 5' 4" per Florida requirements • Roof slope of 20 degrees or less. (See chart for 5/12 roof installat, ). • Single and double section homes require the same number of sys • Triple section homes and double section homes with tag units re ire ona nQdinalsys ems • Diagram represents single section up. to 16' width, double section up to 32' width, and triple section homes up to 48' width. • NOTE: Older homes without vertical tie attachments, require diagonal frame ties/anchors/plates every 5'-4" per Florida regulations Xi Block System Assembly Nut & Washer \ Beam Clamp �[ Bracket J-Bolt 1-112" Tube �o 1-3/4" rube 4 - 1/4"x3/4" -� Self Tapping Screws (2 per Side) Side View TIE DOWN ENGINEERING • 5901 Wheaton Drive • Atlanta GA, 30336 rjE www.tiedownt.com e (404) 344.0000 • FAX (404) 349.0401 , DOWN Longitudinal and Lateral Stabilization for Florida Xi Lateral Xi Longitudinal Xi Longitudinal System Stabilizer Plate & Diagonal C~ "0rilY " System "Only" System L. with Lateral Strut Combo Frame Tie Homes Up To 52' M] 1 p Single Up to 16' Width 2 Combo Systems 2 Lateral only E> a a E> Double Section Up to 32' Width 4 Combo Systems Homes a p i w a IN Triple Section or "Tag" Up to 48' Width 4 Combo Systems 2 Additional Longitudinal Xi Piers up to 80' 101 =V 0 0 0 K Single Double Section/ Triple Section or "Tag" Up to 16' Width Up to 32' Widt Up to 48' Width 2 Combo Systems 4 Co bo Systems/ ateral Only 6 Combo Syste s/2 Lateral Only 4 Lateral Only Note: 5/12 roo pi ch home requires 2 additional systems. 5- lateral systerns.up..to..52',..8.lateral. systems_up:.te.80':.., TIE iO, �. �s v
