Appendix 0 <br /> 71SO Overfill Valve in Tank Shut off Level Worksheet <br /> [:] 61 SO Overfill Valve In Tank Shut off Level Worksheet <br /> M2gM# It This is meantto be supplemental worksheet and not a substitute to fallowing the installation <br /> m <br /> janual instructions. All length measurements are In inches. Please contact the Authority Having Jurisdic• <br /> •tion (AW) 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 lift . <br /> Take the following measurements with the valve in - i <br /> stalled in the tank: w i `=S - <br /> Distance from the 7159 Inlet tube flange to the cast Y ` <br /> lug In the 71 SO body (see figures), uppef tube length . <br /> Note; the Upper Tube Length must be at least IV to in- f <br /> dude the protective bend In the tube, !! <br /> (D ) ( li <br /> DistarKe from the 71 SO Inlet tube Marne to the top and <br /> bottom of lower tube, valve length . <br /> ( W) = � ( �1 Upper <br /> (U ) tube <br /> Distance from the 7150 Inlet tube flange to lite bottorn <br /> of the tank.
