(shown Above]) <br /> (For Steel Pier) 4V, C ?ivi"- 111'7 <br /> REQUIREMENTS <br /> • Install in any type soil, 48 (175 —275 lbs.) or better. <br /> • Main Rail spacing must be 75.5" —99.5", 112" exception with proper strut. <br /> • Maximum pier height at system is 48". Jan 22. 2018 <br /> • Wind Zones II & Ill require sidewall anchors for up lift. check <br /> manufacturers requirements. <br /> • Maximum vertical projection at sidewall is 9' wall and roof rim (9' wall and 12" eave). Higher walls <br /> may be used, when possible for design loads to be adjusted accordingly. <br /> • Longitudinal strut angles need to be no more than 50 degrees and no less than 25 degrees. See page 4. <br /> • The Xi2 ground pad is installed under, and serves as the Tooter for one of the piers required by the home <br /> manufacturer installations instructions. No other pad needed at this location. <br /> • Two systems designed to work in conjunction with each other must be placed as evenly as possible. Measuring <br /> from the center of block/pier on the Ground Pad, systems are to be placed no less than 2' and no more than 10' <br /> from each end of home. Components of the Xi2 system such as the longitudinal strut and connecting <br /> hardware may extend beyond the pier location. Additional systems per instructions, see page 4. <br /> • For roof slopes greater than 20 degrees, (4.37" in 12" Pitch) see page 4. <br /> • This System only replaces normal lateral frame tie and or longitudinal end tie anchorage. The home <br /> manufacturer may require additional vertical anchor ties that are unique to a home's design. These locations <br /> may include shear walls, marriage line ridge beam supports, and rim plates. Check the manufacturer's <br /> installation instructions for set-up requirements. <br /> Xi2 components exceed HUD code 3280.306 g `Anchoring equipment exposed to weathering shall have a <br /> resistance to weather deterioration at least equivalent to that provided by a coating of zinc on steel of not less <br /> ciitt <br /> than 0.30 ounces per square foot of surface coated. <br /> /3-2.��./(:J--7 c. yc;y. y/y• 7$4; <br /> =ti .5cNet • <br /> instruction NQ9108 <br /> TIE DOWN ENGINEERING • Atlanta, GA 30336 t TIE---- <br /> www.tiedown.com (404) 344-0000 DOWN <br /> l'ii,ill l MINI, <br />
