Appendix B (TYPE) AUTO LIMITER II Overfill Valve In Tank Shut Off Level Worksheet `'.Important: This is meant to be a supplemental worksheet and not a substitute to following the installation manual instructions. All length measurements are in inches. Please contact the Authority Having Jurisdiction (AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off, capacity in your region, as well as take into account other considerations such as extreme tank tilt. Take the following measurements with the valve Installed in the tank: Upper tube to shut off point on valve. (D) = 47 (VII) = 127 (U)= 125 Top of tube flange to tank bottom. (B) = 130 From the tank calibration chart: provided by tank manufacturer find the dipstick number (Y) which corresponds to the 100% volume. (Y) = 9,842------ 1. To determine shut-off percentage: Subtract upper tube length (D) from distance to tank bottom (B) (X) = (B) — (D) - 2" _ (OPW) (X) = (B) --- (D) = 83 (Other) Using the tank calibration chart provided by the tank manufacturer determine the tank capacity at the calculated (X) dimension and the 100% volume (Y) tank capacity. (X) tank capacity in gallons = 9,299 (Y) tank capacity in gallons = _ 9,842 SO% = (X) capacity I (Y) capacity x 100 = 94.4% FACILITY: (TANK 1 PREMIUM) iCHEVRON 6633 PACIFIC AVENUE STOCKTON, CSA 95207 NOTES: Valve was removed and functional. i I O i (a) Upper Tube i i (w) Valve,; Length, bottom of cut i r (g) To Tank ti (u) (Y) ll Valve Tank t I Length, Chartf top of cut _ 100% Volume Dipstick Note: The overfill valve must be installed per AHJ requirements and all applicable local, state, and national codes.
