All length measurements are In Inlches. Please contact the Authority Harting Jurisdic- <br /> tion(AIHU)and review local,state,and national codes to determine the regulatory requirements governing <br /> shut-off capacity in your mg Ion,as well as take into account other considerations such as extreme tank tilt. <br /> Tank ID: PREMIUM(PREMIUM) <br /> Take the following measurements with the valve in- <br /> stalled in the tank: <br /> Distance from tha 7150 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 <br /> include the protective bend in the tube. <br /> (D); 62.5 <br /> Distance from the 71 SO inlet tube flange to the top and <br /> bottom of louver tube,vahre length.
