MAR 21 2019 <br /> Appendix C ( continued ) <br /> 7150 Overfill Valve in Tank Complete Shut Off Level Worksh9RONMENTAL H4=ACTH <br /> Important: This is meant to be supplemental worksheet and not a substitute to following fhe installajlo NI'T <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 g verni <br /> shut- off capacity in your region, as well as take into account other considerations such as extreme tank til <br /> Take the following measurements with the valve in- <br /> stalled in the tank: - -_ <br /> Distance from the 71 SO inlet tube flange to the cast <br /> lug in the 7150 body ( see figures), upper tube length . <br /> Note : the Upper Tube Length must be at least 16" to in - <br /> clude the protectivebendin the tube . <br /> ( D ) <br /> �� IJ <br /> Distance from the 71 SO inlet tube flange to the top and <br /> bottom of lower tube, valve length . <br /> (W) <br /> ( U ) <br /> Upper <br /> Distance from the 71 SO inlet tube flange to the bottom Tube <br /> of the tank. Note : If a tank bottom protector is present it - -may be necessary to add this thickness to dimension <br /> (OPW 6111 & 61T P models add 0 . 6") <br /> (B ) _ (W) Valve <br /> .1 <br /> Length, q <br /> bottom <br /> From the tank calibration chart provided by tank manu- <br /> facturer find the dipstick number (Y) which corresponds of cut <br /> to the 100°/A vof�ume .

If the overfill valve is set= above the allowable <br /> shut-off percentage the overfillalve must be removed <br /> and replaced . <br /> Note : ' his Appendix only applies to valves installed per Appendix C .
