All length measurements are in inches. Please contact the Authority Having Jurisdic- <br />tion [AHA and review Iocal, 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 />Take the fallowing measurements with the valve in- <br />stalled in the tank: <br />Distance from the 71 SO inlet tube flange to the Cast <br />lug In the 7150 body (see figures), uppertube length. <br />Note: the Lipper Tube Length must be at least 16' to <br />include the proteecti-v�e bend In the tube. <br />(o)= <br />distance from the 71$0 inlet tube flange to the top and <br />bottom of lower tube, valve length. <br />[v1= nth -- <br />Distance from the 7154 inlet tube flange to the bottom <br />of the tank. Note: If a tank bottom protector is present it <br />may be necessary to add this thickness to dimension <br />(OPW 6111 & 61 TP models add 0.6") <br />(a)= /7 <br />From the tank calibration chart provided by tank manu- <br />factu rer find the dipstick number M which corresponds <br />to the 100%vgIVme. <br />tri = �1 <br />1.
