All length measurements are in intoes. Please contact the Authority Having Jurisdic- <br />tion (AHA 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 />Tank ID: Prem(PREMIUM) <br />Take the following measurements with the valve In- <br />stalled In the tank: <br />E]istance from the 7150 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 <br />include the protective bend in the tube. <br />65.125 <br />Distance from the 71 SO inlet tube flange to the top and <br />bottom of lower tube, valve length. <br />(M=. <br />Distance from the 71 SO inlet tube flange to the bottom <br />of the tank.
