All length measurements are in inches. please contact the Authority /laving Jurisdic- tion IAHJI and review local, state, and national codes to determine the regulatory requirements governing shut-off rapacity in your region, as well as take into account other considerations such as extreme tank UK. Take the following measurements with the valve in- stalled in the tank: Distance from the 7150 inlet tube flange to the cost lug In the 71 SO body (see ftgures), uPPer tube length. Note: the Lipper Tube Length must be at least 16" to include the protective bend In the tube. (D)= Distance from the 71 SO inlet tube flange to the top and bottom of lower tube, valve length. (W = �f�_ (U)=fyl� __ Distance from the 7150 inlet tube flange to the bottom of the tank. Note: if a tank bottom protector is present it may be necessary to add this thickness to dimension (DPW 5111 & 61 TP models add GY) (B)= -/ -2 Lj - From the tank calibration [hart provided by tank manu- facturer find the dipstick number (Y) which corresponds to the 100% vc�l me. (Y) = �1_. 1. To determine shut-off percentage: Subtract upper tube length (p} from distance to tank bottoln (Bi (X) = (B) - (O] - 7" = ..J_ Using the tank oliibratlon chart provided by the tank manufacturer determine the tank capacity at the cal- culated (X) dimension and tate 100% volume (Y) tank Capacity.

If the overfill valve is set above the allowable shut-off percent- age the overfill valve must be removed and replaced.
