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 71 SO inlet tube flange to the cast <br /> lug in the 71 SO body(see figures),upper tube length. <br /> Mote: the Upper Tube Length must be at least 16"to in- <br /> clude the protective bend in the tube. <br /> Distance from the 71SO inlet tube€lange to the top and <br /> bottom of lower tube,valve length. <br /> (w)= 1 (D) <br /> (U)_ X112 Upper <br /> Tube <br /> Distance from the 7150 inlet tube flange to the bottom <br /> of the tank.
