Fla pp (_ 1 D31'� �a1G <br /> Appendix 8 <br /> 71 SO Overfill Valve in Tank Shut off Level Worksheet <br /> Important: This is meant to be supplemental worksheet and not a substitute to folloOng the installation <br /> manual instructions. All length measurements are in inches. Please contact the Authority Having Jurisdic- <br /> tion(AHJ)and review local,state,and national codes to determine the regulatory requirements governing <br /> shut-off capacity in your region,as well as take into account other considerations such as extreme tank tilt. <br /> Take the following measurements with the valve in- <br /> stalled in the tank: <br /> Distance from the 7150 inlet tube flange to the cast <br /> lug in the 71 SO body(see figures),upper tube length. <br /> Note: the Upper Tube Length must be at%east 16" to in- <br /> clude the protective bend in the tube. <br /> (o) _ Z <br /> Distance from the 71$0 iniet tube flange to the top a-,d <br /> IJ fl:::SSI VI IVVYCI L _ZYCIvC "moi <br /> = <br /> 3 <br /> (W) r r u7 ' <br /> upper <br /> Tube <br /> D stance from the 71 SO inlet tube Flange to the bottom <br /> of the tank.
