Appendix B <br />(TYPE) AUTO LIMITER II Overfill Valve In Tank Shut Off Level Worksheet <br />Important: This is meant to be a supplemental worksheet and not a substitute to following the installation <br />manual instructions. All length measurements are in Inches. Please contact the Authority Having Jurisdiction <br />(AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off . <br />capacity in your region, as well as take into account other considerations such as extreme tank tilt. <br />F ,Take the following measurements with the Valve <br />Installed in the tank: <br />Upper tube to shut off point on valve. <br />(D) = 49 112 <br />(W) M 129 <br />(U) = 127 <br />Top of tube flange to tank bottom. <br />i <br />�'(B) = 932 <br />From the tank calibration chart provided by tank <br />manufacturer find the dipstick number (Y) which <br />corresponds to the 100% volume. <br />(Y) = 9,842 ^ <br />E <br />1. To determine shut-off percentage: <br />Subtract upper tube length (D) from distance to <br />tank bottom (B) <br />i <br />(X) _ (B) -- (D) - 2" _ (OPW) <br />(X) _ (B) — (D) = 82112 (Other) <br />Using the tank calibration chart provided by the <br />tank manufacturer determine the tank capacity at <br />the calculated (X) dimension and the 100% volume <br />(Y) tank capacity. <br />(X) tank capacity in gallons = 9,290 <br />(Y) tank capacity in gallons = 9,842 <br />SO% = (X) capacity 1(Y) capacity x 100 = 94% <br />FACILITY: (TANK 3 - REGULAR 2 - SOUTH) <br />;CHEVRON <br />6633 PACIFIC AVENUE <br />STOCKTON, CA 95207 <br />i NOTES, Valve was removed and functional <br />f <br />T, <br />AN <br />` y <br />(a) <br />Upper <br />Tube <br />(W) <br />Vatve, <br />Length, <br />bottom of <br />cut <br />( <br />ToTank � <br />i <br />i <br />Valve M <br />Length, Tank <br />II top of cut Chan <br />100% <br />Volume E <br />I Dipstick <br />Note: The overfill valve must be installed per AHJ <br />requirements and all applicable local, state, and national <br />codes. If overfill valve is set above the allowable shut-off <br />percentage the overfill valve must be removed and <br />replaced. For reference 40 CFR part 280 Subpart a Section <br />280.20 overfill valves should be set to a maximum of 95%. <br />
