Appendix B H&S Energy#3035 Diesel Tank <br /> 71 SO Overfill Valve In Tank Shut Off Level <br /> Worksheet <br /> Important: This is meant to be a supplemental <br /> worksheet and not a substitute to following the <br /> installation manual instructions. All length <br /> measurements are in inches. Please contact the <br /> Authority Having Jurisdiction (AHJ) and review <br /> local, state, and national codes to determine the <br /> regulatory requirements governing shut-off <br /> capacity in your region, as well as take into <br /> account other considerations such as extreme <br /> tank tilt. (p) <br /> Up oer <br /> With valve installed in the tank take the following Tube <br /> measurements: Length <br /> Distance from the 71 SO inlet tube flange to the cast <br /> lug in the 71 SO body (see figures), upper tube <br /> length. Note: the Upper Tube Length must be at ( ) <br /> least 16"to include the protective bend in the tube. v ve <br /> (D) = 83.375 Len gth, <br /> bottc m of <br /> Distance from the 71 SO inlet tube flange to the top c At <br /> and bottom of lower tube, valve length.
