2 . To determine lower tube distance from tank 4. To determine float alignment : <br /> bottom to bottom of cut . <br /> Looking into upper tube (see figure) the float should <br /> Subtract valve length (W ) from distance to tank be aligned along the length of the tank . If float is <br /> bottom ( B) not aligned properly adjustments need to be made . <br /> (V) = ( B) — (W) = 5 <br /> Note : Lower tube clearance must meet tank <br /> manufacturer requirements and all AHJ , local , <br /> state , and national codes . Typical clearance is <br /> about 4" . If lower tube clearance is not met valve <br /> must be removed and adjusted to meet these <br /> requirements . <br /> Cast lug <br /> in 71 SO <br /> body <br /> Float direction <br /> 3 . To determine lower tube distance from tank <br /> bottom to top of cut . <br /> Subtract valve length ( U ) from distance to tank <br /> bottom ( B) <br /> (T) = ( B ) — ( U ) = 5 <br /> Note : Lower tube distance from tank bottom to top <br /> of cut must meet all AHJ , local , state , and national <br /> codes . For reference per 40 CFR 63 subpart <br /> CCCCCC / NESHAP the lower tube can be more View into drop tube from above <br /> than 6" from the bottom of the tank . If lower tube <br /> distance is not met valve must be removed and <br /> adjusted to meet these requirements . <br /> RECEIVED <br /> JAN 17 2024 <br /> ENVIRONMENTAL HEALTH <br /> PERMIT/SERVICES <br />
