Appendix A DEC 0 9 2P <br /> 7150 overfill Valve Upper Tube Calculation Worksheet F=NVIRONMENTA <br /> Important; This is meant to be supplemental worksheet and not a substitute to followiWokaillstrsif£ti6Ti^1'1" <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 governing <br /> shut-off capacity in your region,as well as take into account other considerations such as extreme tank tilt. <br /> Desired tank capacity for shut-off: SO%= <br /> Dipstick Number on Tank Chart that corresponds to SO%= <br /> Tank Diameter(100%volume) (Y) �X) <br /> Upper Tube Reference NumberZ=Y-X _ (Z) <br /> 2 <br /> Upper Tube Depth Inside Tank C=Z-2" 0 (C) <br /> Distance from top sealing surface for 71 SO Lip'to inside the <br /> z <br /> top of Storage Tank' A= <br /> For Non-Testable 7150 models only <br /> In all cases for non-testable 7150 models,the top of the valve body must protrude at least 6'/z"into the tank to <br /> provide a minimal clearance for proper operation?
